How to assemble a greenhouse from frames with your own hands. How to make a greenhouse from window frames

And even metal-plastic - what greenhouses are built from! Did you know that an inexpensive, easy-to-build, but very reliable and generally good structure can be built from old window frames remaining, for example, after replacing wooden windows?

Next detailed instructions will help carry out construction without any problems.

Making a foundation for a greenhouse

The finished greenhouse made from frames will weigh quite a lot, so it is necessary to make a separate foundation for it. We will build a full-fledged column-type support.

First step. Clearing the construction site. We remove garbage, uproot stumps and bushes, weeds, etc.

Second step. For convenience, we mark the site according to the size of the future greenhouse. We drive pegs into the ground around the perimeter and in the corners and stretch a rope between them.

Third step. In the corners and at three-meter intervals along each side of the greenhouse, dig holes half a meter deep. In a good way, the depth of each such hole should exceed the freezing level of the soil.

Fourth step. We fill the bottom of the holes with about a 10-centimeter layer of crushed stone and compact it thoroughly.

Fifth step. We make formwork. It is needed if the columns will be filled with concrete. The simplest option is to install a hollow pipe with a diameter of 10-15 cm in each hole (asbestos-cement pipes are suitable), level them, insert reinforcement, fix the structure (can be lined with bricks) and fill it with concrete.

Also, support pillars can be built from bricks or stones, using ordinary cement-sand mortar to fasten the elements.

Sixth step. We lay timber on top of the supports. At the corners we fasten the beams with iron plates. We attach the timber directly to the supports in a suitable way, for example, with anchors.

Building a greenhouse: a step-by-step guide

The structure in question can be built in different ways. First, we will describe the procedure for constructing a structure whose roof will be made of polyethylene, and at the end we will provide guidance on how to build a more durable frame. It can be covered with polycarbonate or other material.

The first stage - preparing the building material

Preparing window frames for work. We remove handles, hinges and other existing fittings.

We remove the old paint and treat the “bare” wood. At the same stage, it is recommended to temporarily remove the glass so as not to damage it during the process of fastening the frame elements.

We carefully seal the vents that will not be used in the greenhouse in the future. You can even dismantle parts of the frames with windows, if you like.

The presence of several opening windows is a big advantage - you don’t have to bother with arranging the ventilation system.

Stage two - laying the floor

We temporarily set the frames aside and begin arranging the floor. Our base is columnar, so there will be no difficulties in creating the floor.

First we provide drainage. If the water stagnates, the wooden elements of the structure will begin to rot.

To equip the drainage system, we dig a trench about 150 mm deep and fill it with fine crushed stone or gravel to about 5-7 cm. We fill another 3-5 cm of the trench height with sand and compact it thoroughly.

Important! The filling must be done so that the finished surface has a slight slope in the direction of the previously equipped drain hole.

To decorate the interior of the greenhouse, we install borders made of plastic or wood on the sides of the passages. Such a decorative element will simultaneously perform a functional task, preventing the earth from falling onto the path.

If desired, you can decorate the floor using other materials. There are several options.

Find out some interesting ways to do this from our new article.

The third stage - building walls

First we build a frame for attaching the frames. We use high-quality wooden boards with a thickness of about 50 mm, approximately corresponding to the thickness of the window frames. From such boards we make the lower and upper trim. When arranging the lower perimeter, we use boards in 2 rows. Thanks to this, the finished greenhouse will be slightly taller.

We make vertical posts from timber. The best option is elements with a cross section of 150x150 mm. Such beams are guaranteed to withstand the weight of frames and related materials.

We attach the vertical posts to the support posts using a suitable method. We lay the bottom trim boards between the posts. We fasten the boards to the posts with self-tapping screws. We attach the frames with their long sides to the posts and boards of the lower trim. We use self-tapping screws.

We lay the top trim boards along the upper edges of the frames and racks. We also fasten it using self-tapping screws.

We fill the gaps between the frames and frame elements with polyurethane foam. For greater stability, we nail support bars to the inside of the frames.

Advice! To make the entire structure more stable, we include vertical supports in its composition. It is better to do them while forming the frame. To do this, we dig holes, install supports in them (a section of wood that will be in the ground is first wrapped in roofing felt or tarred) and pour cement or concrete. We fasten the supports to the vertical support posts using nails.

We check the structure again for any cracks. If we find any, we blow them out with foam. Only the vents for ventilation can be left free.

We put back the removed glass. Instead of glass, you can use other material, for example, polyethylene or cellular polycarbonate.

Important! If you plan to make a polycarbonate roof, it is better to install the glass after the roofing work is completed.

Stage four - making the roof

Most often, summer residents cover greenhouse frames with plastic film. In such a situation, the load on the frame and base will not exceed permissible standards, and the greenhouse will last as long as possible.

We construct a light sheathing along the upper perimeter of the greenhouse. It can be made from wooden slats, metal profiles and even wire.

Having installed the sheathing, we stretch the film. To secure it, it is most convenient to use special clamps and clamps.

As an option: a greenhouse with a polycarbonate roof

If your budget allows you to purchase cellular polycarbonate for the roof, you can do it. Keep in mind that this design will require a fairly strong frame. For its manufacture, it is best to use profiled pipes, because... a wooden beam is unlikely to withstand such a load.

For more convenience, from pipes you can immediately make support pillars and a greenhouse frame. To do this we do the following.

In this case, it is also better to make the door from polycarbonate, having previously made a metal or wooden frame for its installation.

Helpful advice! To make the greenhouse look more attractive, you can paint its outer surface in the desired color. Interior painting is optional.

Greenhouse made of window frames and polycarbonate

Arrange it at your own discretion. You can equip it with water supply and drainage systems, provide light and installation of all kinds of shelving, racks and other supports for beds, etc. At this moment, all decisions are yours, because... only you can know what your greenhouse should look like from old window frames.

Happy work!

Video - Greenhouse made from old window frames

Greenhouse on personal plot- not a luxury, but a necessity. But what if the budget is extremely limited? Even in this case, a greenhouse can be built - with your own hands: it will not be difficult to build from old frames.

Nowadays, a lot of people are replacing old wooden windows with new plastic ones. In the vast majority of cases, old windows and glass are sent to a landfill. This trash is an excellent building material for building a greenhouse from frames with your own hands.

If you choose windows of the same size, then construction will not be difficult at all. If they are of different sizes, then you will have to try a little.

From old window frames you can build both a permanent and temporary greenhouse.

Temporary structure

Old window frames are wooden, so they will not last very long - 6-8 years. In order to build a temporary greenhouse from them, you do not need a special foundation.

It is enough to place a brick or wooden beam under them to prevent them from rotting too quickly. Our step-by-step instructions will help you assemble a temporary shelter.

Procedure

1. We take out all the glass from the windows and clean them of rags of old paint.. We clog up all the windows that we don’t plan to use.

Advice!
To slow down the decay process, it is worth drying the wood or painting it with oil paint.

1. Unscrew all metal parts(latches, hinges, etc.).
2. We calculate the dimensions of the future building based on the available number of frames.
3. We mark the boundaries of the future building using pegs and twine..

Advice!
Don't forget to check the markup.
The diagonals of the rectangle must be equal.

1. We dig in bricks along the string so that the top edge of the brick is raised above ground level by 2-3 cm. We choose the digging step so that each frame rests on three bricks.
2. We assemble the frame of the building from 50x50 mm timber. The height of the frame must be at least 170 cm. To reduce the cost of the structure, you can use a dry board with a thickness of at least 30 mm. The supporting columns of the frame should be positioned so that the joints of the windows fall on them.

1. We fix the perimeter windows. They need to be nailed to the frame as often as possible to increase the strength of the structure.

Note!
We install the frames with the windows facing outwards, so that they do not open in the wind.

1. Making the roof frame. Since we have a greenhouse without a cushion, it is not recommended to cover it with the same glass windows, so as not to increase the weight of the structure. There can be two roofing options - film or polycarbonate. Our structure is as budget-friendly as possible, so we are not considering the option of polycarbonate.
   The roof can be either single-pitched or double-pitched.

• Single-pitch. To install it, we increase one side row of frames upward by 60-100 cm, depending on the width of the building. To do this, you may have to cut the frames and knock together windows of the required size.

Note!
The height difference for a film greenhouse should be approximately 25-30 cm for each meter of run length.

After this, the cross beams can be laid. They can be made from solid timber section 50x50 mm. You can also splice disassembled parts of windows, but then you will need to install supports.

Note!
The installation pitch of the rafters should be such that it is convenient to tension.
For example, if the film meter width, then the rafter installation step is 90 cm.

• Gable. We lay crossbars made of 50x50 mm timber on top of the finished frame frame. From the same timber we make roof rafters, which we nail to the crossbars. The height difference from the roof ridge to the walls should be 50-70 cm. Along the top of the rafters, the rafters can be connected to each other with window trims.

Note!
To prevent the frame from moving apart under the weight of the roof and precipitation on it, it may be necessary to install supports under the cross beams.

1. We hang entrance doors, fortunately there are enough various loops and latches exact amount.
2. Carefully seal all cracks. It will be used construction foam, silicone sealant and even ordinary clay. In the latter case, the clay should be mixed with fluffy tow as a binding filler.
3. Inserting glass into the side walls. If there is not enough glass, then these places can be filled with polyethylene or polycarbonate residues.
4. We stretch the film onto the roof.
   In order for the film to sag as little as possible, the order of its tension should be as follows:

• We cut pieces of film along the length of the roof with a margin of 40 cm;
• If necessary, cut the pieces lengthwise;
• We roll out the first piece over the roof so that the film hangs equally on both sides;
• We nail one edge through the slats (glazing beads, shingles);
• We stretch the film from the middle to the edges with a fold around the next rafter and fix it with nails or a stapler;
• We repeat the operation with the following pieces.

1. We fix the side edges of the roofing film through the slats.

The temporary greenhouse made from old frames is ready. This design is not suitable for use in winter period, so for the winter the film from the roof needs to be removed. Otherwise, not only the film may break, but the entire structure may collapse.

In order for a building to successfully withstand winter, a more serious approach is needed. The price of a capital structure is higher, however, the strength and reliability are several times higher.

Capital building

In order to build a permanent greenhouse from old window frames, you already need a foundation. A greenhouse made of frames standing on a concrete pad will last much longer, especially if you take care of the wood. Such a structure can already be covered with polycarbonate, or a roof can be made from the same window frames.

Sequence of work

There is nothing special about pouring the foundation for such a structure, so we will not dwell on it in detail. For a small greenhouse, a concrete pad the width and depth of a shovel will be sufficient. For a larger greenhouse, for example, 3x6m, the foundation depth is 45-50 cm, width 25-40 cm.

The edge needs to be raised above the ground by 10-15 cm. Pieces of corners along the long sides should be immediately concreted into it for subsequent fastening of the frames.

The corners should protrude from the concrete by 5-10 cm.

The foundation hardens in about a week or two.

After this, you can proceed directly to construction:

1. We lay out square columns 170-180 cm high from brick at the corners of the foundation. The same columns can be laid along the long sides of the building so that 2-3 frames are placed between them.
2. We prepare the frames for construction in the same way as in the case of a temporary structure.
3. In the middle of the brick columns we make the upper and lower frame frames from 50x50 mm timber or boards at least 30 mm thick. We screw the bottom trim to the foundation corners.

Note!
The timber of the upper frame should lie on top of the posts, and the bottom – directly on the foundation.

1. We assemble the side and end walls of the greenhouse in the same way as in the temporary shelter option.

1. The roof is arranged in the same way. In the case of a lean-to greenhouse, the side posts should be increased to the required height.
2. If the roof is made from old windows, then the distance between the roof rafters should be such that the glazing frames fit between them with a slight interference.
3. Next, we hang the door and seal all the cracks.
4. To make it convenient to walk, the central passage in the greenhouse can be deepened by 15-20 cm.

Summary

Thus, if you have the skill and minimum quantity money, a greenhouse of this kind can be built. To begin with, you can try to build a temporary structure, and then think about a more permanent one.

You can find out even more information by watching the video in this article.

Don’t worry about where to dispose of old wooden or plastic windows after renovation. Using this instruction and useful tips from summer residents, build a greenhouse or a full-fledged greenhouse from window frames with your own hands - and you will pamper yourself with early vegetables, and you will be known as a master among your neighbors. Study in detail how to make a structure reliable and airtight so that it solves the assigned tasks, withstands bad weather and lasts on the site for several seasons.

Pros and cons of a greenhouse made from old window frames

Does the prospect of getting a practically free greenhouse warm your soul? Don’t rush to rub your hands in anticipation of future profits from greenhouse farming - a cheap greenhouse has both advantages and disadvantages. For example, such a greenhouse cannot be made by yourself in no time, and both in person and in the photo the structures are significantly inferior in appearance to polycarbonate ones. You will understand whether this solution is right for you when you study other nuances.

Mini-greenhouse from an old window

Features of frame greenhouses

A greenhouse made from window frames, in addition to cost, has other advantages:

• windows, if they have retained their integrity, retain heat well;
• if there is glass, there is no need to spend money on covering material;
• the structure turns out to be quite light, and the soil quickly warms up;
• the window frames already have vents, which means the ventilation issue has been resolved;
• a leaky element can always be replaced with a similar one.

Greenhouse from a second-hand window

On the other hand, a self-made greenhouse made from window frames even in the photo looks, to put it mildly, unpresentable. If you approach the matter responsibly, its installation will take at least a week. Therefore, those who value their own time as worth their weight in gold or worry about landscape design of their own plot, they do not undertake the construction of a frame greenhouse.

The disadvantages also include a large number of joints and connections between frames that are often of different sizes. They all need to be sealed with sealant so that precious heat does not leak out into the cracks. Such a greenhouse will have to be greased, tinted, and repaired throughout its entire service life. Besides:

• a greenhouse assembled from “pieces” is difficult to dismantle and move to another place;
• glass breaks easily and when working close to the walls of the greenhouse, you need to be careful;
• the greenhouse turns out to be heavy - you can’t do without a foundation.

Window frames shade the greenhouse by 30%

We must not forget that under glass, which blocks ultraviolet B and C, which is beneficial for plants, crops grow more slowly than under a light-transmitting film. Is it worth abandoning the idea completely because of these features? Of course not, they just need to be taken into account in the design homemade greenhouse and take a responsible approach to choosing a place for it.

Selection of location and design

Before you make a greenhouse from window frames, decide where it will be located. The question is far from idle: not only its size and shape, but also the internal microclimate and productivity directly depend on the location of the structure. Of course, these recommendations are not feasible for every site, but if possible, try to follow them at least partially:

• so that the greenhouse is well lit and protected from northern winds, install it in front of tall buildings or plantings;
• erect the structure on the southeast, southwest or south side of the site;
• it’s good if there is a hill in this place, otherwise you will have to build a drainage layer;
• analyze the condition of the soil in the selected plot - if the soil is clayey, cover it with gravel and fill it with black soil;
• place the greenhouse for tomatoes as far as possible from the potato plantation - this is important for preventing the spread of late blight;
• Please note that the most successful direction of the roof ridge is considered to be south-northern - this is how the cultivated crops receive maximum amount sun rays from the east and south.

Location of the greenhouse on the site

If you want to extend the agricultural season, also consider the communications system - you will need to provide heating, lighting and watering. To make it easier to do all this with your own hands, it is important that the greenhouse made of window frames is located as close as possible to the energy source.

As for the shape of the greenhouse, choose it based on your goals:

• For a greenhouse nursery, a box-shaped structure tilted to one side is suitable. It is also convenient to organize temporary storage of root crops in the fall.
• It is convenient to grow greens and grown seedlings in a gable mini-greenhouse.
• To get a harvest of cucumbers or tomatoes, you need a greenhouse-house at least 1.8 m high with doors and vents.

The simplest greenhouse nursery

DIY construction stages

To figure out how to build a small but functional greenhouse from old window frames, study step-by-step master class, provided by an experienced vegetable grower, and a video describing the process. First, determine the dimensions based on the number of frames, and then draw a sketch of the greenhouse on a scale and decide on the type of foundation.

Which is better - a foundation or a foundation?

In order to simplify and reduce the cost of construction as much as possible, some summer residents are planning to do without a foundation and simply install the greenhouse on the ground. In professional construction, there is the concept of a foundation - a mass of soil capable of absorbing the load from a structure without deformation. But for this it is strengthened in various ways:

• pneumatic rammer;
• silicatization (introducing a solution of liquid glass into the soil layer);
• cementation (injection of liquid cement mortar).

It is unrealistic and unprofitable to create a foundation strong enough for a heavy greenhouse on your own and without equipment. Therefore, based on your own considerations and material capabilities, you need to choose the material for the foundation. The following options are usually considered:

• wooden beam;
• bricks or blocks;
• reinforced concrete.

Shell block construction

The timber is quickly installed, but it also rots quickly. It can and should be impregnated with resin or wrapped in roofing material, but these measures only briefly slow down the process. A base made of silicate or hollow bricks will not last long, and well-burnt clinker is expensive. It will not be much cheaper to buy foundation blocks, since the technology requires high-quality insulation and insulation, and this will also cost a pretty penny.

The timber lasts for 3–4 years

Some craftsmen manage to adapt railroad sleepers, car tires, and iron pipes into greenhouses. But shallow-depth is considered the most predictable and relatively cheap strip support made of concrete – service life at the right approach exceeds tens of years. To understand how justified such a structure is for a homemade greenhouse made from old frames, study the installation technology.

Tire base

How to pour correctly concrete foundation

Determine the width of the foundation strip according to the type of soil: 20 cm (for loams) or 25 cm (for sandy soils). At the previously selected location, remove the platform and mark:

1. Select the location of the first corner and, using a plumb line, vertically install a peg or piece of reinforcement in its place.
2. Pull the string from it at right angles and at the required distance determine the second and third angles - also mark them with pegs.
3. From the second and third corners towards the fourth, pull the string and, having adjusted the corner, set the last mark.
4. Check the resulting rectangle along the diagonals: they should be equal.
5. In a similar way, mark inner circuit foundation.

Finished trench

Calculate the desired height foundation from the ground as the difference between the height of the window frames and the height of the greenhouse under construction along the floor beams. Mark the calculated size on the pegs and pull the string horizontally.

Now comes the turn earthworks. According to the markings, dig a trench 30 cm deep. The walls should be vertical; if the soil falls, install temporary supports. Check the bottom with a level and, at the slightest slope, level it to the horizontal. Pour sand into the finished trench in layers, pouring and compacting each layer. The thickness of the pillow is 15 cm.

1. Assemble formwork from edged boards and timber.
2. WITH outside install supports to prevent its deformation.
3. Attach reinforcing rods with a diameter of 8–12 mm to the walls of the formwork and tie them together with wire.
4. Mix cement grade 200 with sifted river sand in a ratio of 1:2 or 1:2.5 and dilute with water until it becomes liquid sour cream.
5. Fill the resulting solution with crushed stone - its quantity is the same as sand.
6. Mix the concrete and pour it into the formwork, compacting it in the process using improvised means, a hammer drill or a construction mixer.
7. Level the top layer with a rule or trowel and sprinkle it with concrete sifted through a sieve.

Pouring concrete

The resulting foundation can subsequently be used for more than one greenhouse.

Ready base

Installation of windows and frames

Dismantled windows should be prepared before reuse. Check their condition - dried wood cannot be restored and is not suitable for a greenhouse. Carefully remove old hinges, nails, latches from the frames - anything that is outdated or may interfere with installation. To avoid damaging the glass, temporarily remove:

1. Remove the glazing beads from the window frame, pull out all the glass, marking them according to each opening.
2. Wash glass panels with warm soapy water.
3. Replace cracked glass and add new glass to replace missing glass.
4. Use a blowtorch or paint remover to remove the old coating layer.
5. If necessary, fill the uneven areas.
6. Apply several layers of antiseptic and let the surface dry.
7. Paint the frames exterior paint light color.

Refurbished window frame

The most labor-intensive operation in building a greenhouse from old window frames with your own hands is building the frame. It is optimal if, after replacing the windows with metal-plastic double-glazed windows, the frames remaining are the same size. In this case, lay a sheet of roofing felt on the concrete foundation, and a beam of the lower trim on it. Then, one by one, use dowels to screw the frames to the foundation and tie them with posts and lintels for rigidity.

Plank frame diagram

When installing frames of different sizes with a frame structure, you will have to tinker a little more:

1. Place vertical pillars at the corners of the foundation same height, equal to the height of the largest frame and the width of the bottom trim beam.
2. Rigidly install the top trim around the entire perimeter.
3. Attach the first frame to it with three dowels, and leave its lower edge free.
4. Install the second frame in the same way, but on the other side.
5. Place the bottom beam into the gap between the frames and the foundation and attach it to the foundation and pillars.
6. Cover the remaining uncovered space with a board according to its size - due to their location at the bottom, such inserts will not shade the greenhouse.

The holes are covered with plastic film

Alternatively, the varying height of the frames can be compensated for by polycarbonate inserts, installing them in any location.

Wooden and plastic frames- advantages and disadvantages

The nuances of building a greenhouse from wooden windows, positive and not so good, are discussed above. But increasingly, it happens that pioneer homeowners who were once the first to replace wooden frames to metal-plastic double-glazed windows, we already have to change them too. This means that such material can also fall into your hands. Upon closer examination, metal-plastic in its new “role” has its advantages and disadvantages.

At first glance, the metal-plastic greenhouse is impeccable:

• the design looks modern;
• retains heat excellently;
• equipped with ready-made windows;
• resistant to wind and snow;
• durable and environmentally friendly.

Factory greenhouse made of metal-plastic

After looking at the new windows of the house, someone will even want to invest a sum of money in a capital greenhouse made of metal-plastic frames. However, not everything is so rosy - the windows are still intended for other purposes and have not been tested in greenhouse conditions. Especially many questions arise regarding recovery:

• depressurized frames (one of the common reasons for replacement) are also unsuitable for greenhouses;
• During installation, you cannot pull the glass out of the frames - there is a high risk of damage;
• if the top frame and greenhouse roof are installed incorrectly, an uneven load is applied to the window frame, and the glass unit bursts;
• It is impossible to replace broken glass “on the knee” - you need specialists and equipment.

Drawing of a homemade greenhouse

The greenhouse itself turns out to be non-demountable and heavy - moving it to a new place with your own hands will be extremely problematic. If you have free plastic windows, then why not build a greenhouse out of them. But don't be tempted to buy specifically for this purpose: for the money you can find better specialized solutions.

If you decide to use double-glazed windows, remember: they are installed on bottom trim simultaneously with the installation of frame racks made of wooden beams or steel profiles (the latter option is more reliable). During the process, plastic frames can be drilled with self-tapping screws; the main thing is to know where to do this so as not to damage the valuable material.

Greenhouse made of frames with a polycarbonate roof

So, the task of how to make a greenhouse with your own hands from old window frames is almost solved. All that remains is to cover the structure and thereby protect the plantings from precipitation. There are three ways to do this:

1. Using the same frames as for the walls is only acceptable for greenhouse boxes, since placing a heavy structure with glass over someone’s head is unsafe.
2. Covering with film or spunbond is a simple and affordable solution. True, you will have to build a roof frame and remove the material for the winter.
3. Install polycarbonate sheets - if there are no stocks. This option requires material costs, but no hail is terrible for the greenhouse, and it can be used indefinitely.

Arched greenhouse under polycarbonate

Decide on the shape of the roof - will it be arched or gable. An arched one lets in more sunlight, covering it with film or polycarbonate is a pleasure, but you need to stock up on a metal profile bent on a pipe bender. If you or someone you know does not have this device, switch to a gable roof, especially since you almost never need to remove snow from it.

To build a load-bearing roofing system with your own hands you will need:

• ridge beam 5x5 cm of the same length as the constructed greenhouse;
• timber 15x5 for rafters;
• fasteners and consumables;
• tools - hammer, saw, electric drill, tape measure, axe, plumb line.

Gable greenhouse

The work algorithm looks like this:

1. Treat lumber for roofing with impregnation. Dry.
2. Based on the dimensions of the greenhouse and the pitch between the rafters (60–80 cm), calculate the required number of roof trusses. The roof inclination angle is 25–30 degrees.
3. According to the dimensions, make the first truss from two rafter legs and lower screed. Make all the other trusses using the template.
4. Install the trusses one by one on the top frame frame and secure them firmly on both sides with corners and self-tapping screws.

Wooden truss

Now cut the polycarbonate and, having correctly oriented the canvases (with the stiffening ribs vertically and the side protected from UV rays up), secure them to the rafter system.

Fastening the rafters

Finally, ensure the tightness of the greenhouse you built yourself:

1. Install window panes and secure them with glazing beads (if the old ones are no good, you can buy new ones or replace them with colorless sealant).
2. Hang doors - use balcony doors, just cut them to height first.
3. Seal large holes with polycarbonate remnants, and small cracks with polyurethane foam.
4. Check how the windows close and open, install hinges and hooks to secure them.

Perhaps some points remain unclear - look at the selection of videos to see how homemade summer residents get out of various situations. If you make a greenhouse from window frames, as shown in the instructions, it will serve faithfully for many years.

Video 3: Greenhouse under polycarbonate

With the arrival of spring, every owner of a summer cottage is faced with the choice of buying or building a greenhouse for seedlings. Stores offer the most various options, ranging from simple arched structures made of arcs coated with agrofibre to complex structures made of polycarbonate. But the goal of any summer resident is to grow crops at the lowest cost, which is why greenhouses built from old window frames can increasingly be found on plots. Fortunately, modern windows made of PVC profiles have replaced wooden ones and frames that have served their purpose are dismantled.

Advantages and disadvantages of window frames as a material for greenhouse construction

Prefabricated greenhouses and greenhouses offered by stores are easily installed according to the diagrams supplied with them. But if you have a sufficient number of old window frames and minimal construction skills, almost anyone who knows how to hold a hammer and use a screwdriver can build a greenhouse. Like any material, frames have their advantages and disadvantages.

A small greenhouse can be built from old window frames

Advantages of window frames

This material has the following advantages:

1. Availability of material and its low cost. Old frames can be obtained when dismantling and replacing windows for free or for a small price if you purchase them from an organization engaged in this work.
2. The possibility of constructing a greenhouse in a relatively short time. The frames are easily mounted on a pre-prepared foundation.
3. Long service life. At proper preparation frames and constant care for them, a greenhouse can last about 10 years.
4. Not required special tools and devices. To install a greenhouse, all you need is a hammer, a screwdriver and a building level.
5. Installation on various types of foundation. Depending on the weight of the frames, a strip or column foundation can be poured to build a greenhouse, but you can get by with a simple strapping.
6. The glass maintains the optimal temperature for plants and transmits the maximum amount of light. In case of damage, the glass can be replaced with plastic film.
7. Possibility of combination with other materials. A frame greenhouse can have a roof made of polycarbonate, film or other suitable covering.

A greenhouse made from old frames will last long enough

Plastic, metal-plastic and aluminum frames will last longer, but the cost of the greenhouse will be significantly higher.

The cost of the structure will be significantly higher than that of a greenhouse made of wooden frames

Disadvantages of the material

The disadvantages include:

1. Difficulty in preparing frames for installation. It will require thorough cleaning of old paint, treatment with an antiseptic and fine painting.
2. Requires constant care. During operation, gaps may appear between the frames that will need to be sealed.
3. The fragility of glass. If the foundation subsides or is hit, the glass may crack and will need to be replaced.
4. Limitations on service life. Depending on the material from which the frames are made and their proper processing, a greenhouse can last for several years.

The frames can be painted in one color to make the finished structure look more aesthetically pleasing.

Preparatory work: dimensions, diagram, drawing

On how correctly they are produced preliminary calculations and the installation diagram is drawn up, it largely depends on how much time will be spent on installing the greenhouse. In this case, there will be no need to urgently purchase missing material or make adjustments directly on the site.

Choosing a location for installation

One of the most important factors when building a greenhouse is the choice of location. The future harvest depends on this. It should be level and well lit throughout the day, located away from buildings and trees, and not be in a low area so that water does not stagnate. The greenhouse should be located in the direction from north to south. Based on the site plan and the location of trees and buildings, you can select the installation location and determine the permissible dimensions of the future greenhouse. After this, it is worth starting a more detailed study.

The greenhouse is installed away from the house and tall trees

Preliminary calculations, drawing

Determine the exact number of frames available, write down their size. It's best if they are the same. This will avoid additional height adjustments. After this, you can draw up a diagram according to which the installation will be carried out. This will help determine the installation sequence and mark the location for doors and windows.

On the drawing, indicate the required dimensions and location of the frames

Depending on the exact size of the frames, necessary adjustments should be made. If you need to increase the height of the walls, the windows can be positioned horizontally, attaching them above the main frames.

The height of the walls is increased due to the vents horizontally located above the main frames

Depending on the weight of the frames, you should decide on the type of foundation on which the greenhouse will be installed. If you plan to do gardening quite long term, it is better to install the greenhouse on strip or columnar foundations. If it is planned for 1–2 years, a base made of timber, previously insulated with roofing felt or treated with an antiseptic, will be sufficient.

A greenhouse made of frames can be installed on a columnar foundation

The roof in a greenhouse can be either single-pitched, gable or arched. This largely depends on the material from which they decided to make it. This can be an arched polycarbonate roof or a structure made of frames covered with plastic film.

To fasten polycarbonate, a metal profile and screws with thermal washers are used

Roofs made from glazed window frames are less common. If the slope is insufficient, there is a possibility that in a snowy winter the glass may break under the weight of the snow.

Frames without windows were selected for the roof

You should first draw up detail drawing roofs and consider mounting options.

Tips for choosing window frames and preparing them for installation

When constructing greenhouses, wooden frames are most often used. They are affordable and with the right preliminary preparation can last a long time. Before installation, you need to carefully inspect all frames, putting aside those that have defects. If they become numb during use, they will show signs of rotting - flaking paint, darkened wood color, change in structure. Frames with a high degree of damage should not be used for installation.

You need to choose frames based on their size and condition wooden frame

Frames with minor defects may last for some time. When drawing up a drawing, you need to take this point into account and, if replacement is not possible, provide for installation in such a way that the areas with defects are located in the upper part, near the roof itself. This way they will be less exposed to moisture and will increase their service life.

Due to subsidence of the foundation, the glass in the greenhouse may crack

When preparing for installation you must:

1. Remove all unnecessary hinges and handles from the frames.
2. Using sandpaper or a sander, remove layers of old paint down to the base.
3. To protect against rotting and damage by pests, treat the frames with an antiseptic.
4. Remove the glass so that it is not damaged during installation if assembly is carried out using nails and a hammer.
5. Fix the windows that will be used in a convenient way so that they do not open during the greenhouse assembly process.
6. Vents that are not planned to be opened should be sealed with nails or sealant.

Before installation, the frames are freed from unnecessary parts and cleaned of old paint.

Calculation of the required amount of material

We make all preliminary calculations based on the previously drawn up drawing. You need to calculate the number of frames depending on the size. At standard size frame 1200x900 mm, the length of the greenhouse will be a multiple of 90 cm, and the height will be 120 cm + foundation height + roof height. Taking into account that the optimal width of the beds is 1 m, and the distance between them varies from 40 to 60 cm, the most convenient width of the greenhouse will be 2.7 m, i.e. 3 frames. If the windows are larger, two frames may be sufficient.

The length of the greenhouse is a multiple of the number of frames

Hinged windows are large in size and significantly fewer of them will be required.

If there are few frames, you can make a greenhouse with a pitched roof, attaching it to a house or other building on the south side.

Besides required quantity frames, you will need:

1. Entrance door. You can use standard balcony door, if necessary, shortening it, or you can make it yourself according to the size of the opening.
2. Bars for building a frame. For a small greenhouse you will need 4 bars of length equal to the height of the building. If a long structure is planned, support beams can be used to strengthen it.
3. Foundation materials. For strip formwork, you will need formwork material - posts and boards, a mixture of concrete, crushed stone and cement, reinforcement or large stones. For an ordinary wooden foundation, you will need a beam 15x15 cm long, equal to the perimeter of the greenhouse, and roofing felt for waterproofing.
4. Anchor bolts, screws.
5. Wooden bars for rafters. Depending on the type of roof, their number will vary significantly. The largest quantity will be required for gable roof.
6. Roofing material. This can be polycarbonate with a thickness of at least 6 mm or polyethylene film.

Tools required for work

During the installation of a greenhouse you will need:

• cord and pegs;
• hammer;
• screwdriver;
• a circular saw;
• building level;
• drills of various diameters;
• square;
• roulette;
• shovel;
• polyurethane foam.

During work, it is convenient to use a tool with a battery or a power tool

Detailed instructions for making a greenhouse

When constructing almost any greenhouse, the main steps are:

1. Marking the installation site. Using pegs and a cord, we mark the place where the greenhouse will be installed. If a strip foundation is planned, we determine the width of the formwork and, by marking it, dig a trench about 40 cm deep.

   For a strip greenhouse you need to dig a trench

2. Construction of the foundation. For the strip foundation we install formwork from boards. We strengthen their rows with pegs and place reinforcement or large stones inside. Then we fill the channels with pre-prepared cement mortar. Drying time is about 5 days. Only after this can you begin further work.

   Pouring is done into pre-prepared formwork

3. To install the corners of a columnar foundation, you can use a metal pipe, brick, gas silicate blocks. The timber crown is mounted at the installation site. The bars are fastened with metal corners, and a rod is driven into the ground at the corners for reliable fixation. To prevent rotting, paving slabs or other material can be placed in the corners and in the center of each side of the base.
4. Making beds. Before installing the frame, it will be convenient to make beds and design paths between them. Depending on the location of the entrance to the greenhouse and their number, there may be different options for the location of the beds.

   When arranging a greenhouse, it is important to position the beds correctly

   5. There are many types of path design. These can be paving stones, paving slabs, bricks or stones, which are laid in a pre-prepared trench 10–15 cm deep with a sand cushion 5–7 cm high. Alternative option- backfill path made of sand and gravel.

   To design the paths, small trenches are pre-dug

   6. Sand or gravel is poured into a trench 5–10 cm high. It is permissible to use wood mulch or straw at your discretion.

   Paths can be mulched with sawdust, straw or other material

   7. Installation of the frame and fastening frames to it. We cover the foundation with strips of roofing felt and, using anchors, install beams for the lower frame on top of the roofing felt. For structural strength, we connect these elements together with steel corners. After this, we make markings for installing vertical supports. Using steel corners, checking the accuracy of the vertical lines using a level, we fasten the corner posts, and then, if necessary, install intermediate ones.

   The greenhouse frame is prepared for installation of frames

   8. Using bars, we make temporary fixation so that the racks do not bend from their own weight. After installing all the vertical elements on the racks, we attach the upper frame using corners - it will not allow the elements to tilt under their own weight. Only after final installation frame, we remove temporary supports. Metal pipes buried in the soil can be used as racks. To attach the frames to the frame, it is best to use self-tapping screws or self-tapping screws. This will eliminate the possibility of damage to the glass. It is optimal to attach the frames directly to the timber in the holes that are already in the frames.

   Frame mounting points can be sealed with foam

   9. After completing the installation, the gaps that have formed between the racks and frames must be sealed with polyurethane foam. This will prevent drafts and cold air from entering the greenhouse.

   The gaps between the frames and the frame are sealed with polyurethane foam

   10. Construction of the roof. The frame of a gable roof consists of two vertical gable posts, a ridge and rafter legs on either side of it. First of all, the racks are installed, then the beam is thrown from one rack to another - it will act as a ridge. The rafters are attached to it.

   For a long greenhouse you need to install additional racks

   11. If the greenhouse made of frames is long, then we install additional ones between the main rafters. The frame is mounted using steel angles and self-tapping screws. Attached to the finished frame roofing material. If it is polycarbonate, then we install it using a special profile and self-tapping screws with thermal washers; if it is a polyethylene film, we install it using wooden slats.

   The film is attached to the rafters using wooden slats

   12. Lastly, install the door and sew up the gables.

Different types of greenhouse foundations

To build a greenhouse, depending on the weight of the frames, you can choose several foundation options. Some of them are easy to install and do not require much time, while others may take several days to erect.

Ready-made greenhouses from stores, made of cellular polycarbonate and aluminum profile, very beautiful. It’s hard to argue with this, but, unfortunately, you have to pay a lot for such beauty. The cost of ready-made greenhouses is too high, so not every gardener, even a very avid one, can afford to make such a purchase. There is a way out - to make a greenhouse yourself. This will require ingenuity, desire and skillful hands.

Let's consider a method for making a greenhouse from window frames. For work you will need whole wooden frames, without broken glass.

Advantages of greenhouses made from window frames

Having a greenhouse will improve the harvest. A greenhouse is especially helpful in the cold spring, when it is not yet possible to plant plants in open ground. When planting seedlings in a greenhouse, the plants will begin to grow and develop quickly, and will bloom with the arrival of the first warmth.

Most city residents are replacing old wooden window frames with modern plastic windows. After replacement, old frames are usually disposed of. And in vain, because not everyone knows how to use this spent material. If you have old window frames, you can build a good greenhouse. Glass in this design helps maintain optimal temperature regime for growing various types vegetable crops. Using wooden frames will create a durable frame that will support the structure for many years.

Greenhouse made of wooden window frames

Window vents can be used to provide ventilation in the greenhouse. They can also be used to regulate the temperature. Building a greenhouse will not take you too much time. This is a simple process, the main condition for success in which is following the step-by-step instructions.

Preparation of materials

The work will only require a few window frames, so finding materials should not be too difficult. If you don’t have old products lying around in your garage or on your balcony from the time you replaced your windows, then contact your neighbors or friends. Some of them definitely have the necessary frames at home. At worst, you can contact representatives of the company that installs plastic windows. After completing the repairs, they throw the old window frames into a landfill. By reaching an agreement with them, you will solve the problem of preparing the material.

There shouldn't be any problems finding old wooden windows.

Having collected a sufficient number of products, it is necessary to estimate the location of each frame in the design of the future greenhouse. After this, you can begin the creative process. If the dimensions of the frames are not the same, then they can be adjusted using sealant, polyurethane foam, and self-tapping screws.

Construction stages

Before starting construction work, you need to consider optimal location window frames so that during installation the greenhouse will be level and symmetrical. It is advisable to use frames of the same height, because this will simplify preparatory work(no need to adjust sizes).

DIY greenhouse from old windows

Next you need to calculate the width of the greenhouse. To do this you need to draw up a drawing future design. When creating a drawing, do not forget to take into account the number of beds and their location. The standard width of beds in greenhouses is 100 centimeters, and the width of the passage is 50. The width between the beds should be selected so that a person can easily move between them with a small wheelbarrow.

Construction of the foundation

This process begins not with digging a pit, but with searching suitable place.

When choosing a location for the foundation, you must adhere to the following requirements:

• protection from strong winds;
• good lighting of the area;
• no shading due to tall trees or buildings;
• location (it is desirable that the greenhouse be located from north to south).

Important! Soil also plays an important role when choosing a location. Wet or swampy soil will lead to subsidence of the building, so dense and dry soil is necessary for construction.

Concrete and brick foundation for a greenhouse

It’s great if there is a sand layer under the earthen layer. If it is missing, you can make a pillow for the foundation yourself. To do this, it is necessary to evenly cover the clay soil with a layer of gravel. After this, apply a layer of sand on top - no more than 20 centimeters. Before construction, it would be a good idea to check the location groundwater. If they are located at a depth of one and a half meters or less, find another place to build the greenhouse.

Step-by-step construction of a strip foundation

Step 1. Dig a shallow trench according to the drawing. Its depth should be about 40 centimeters.

Foundation trench

Step 2. Make formwork. To do this, you need to place the boards along the edges of the dug trench, securing them with wooden pegs. You can also secure it using conventional electrodes bent in two. It is advisable to cover the boards with film so that they do not stick to the cement.

Wooden formwork

Step 3. If possible, install reinforcement along all dug channels. If there is no suitable wire, place large stones at the bottom of the trench.

Step 4. Fill the trenches with prepared cement mortar, adding a little crushed stone to it. Make sure there are no voids in the foundation. The cement grade M-200 or M-300 is suitable for the solution.

Pouring the foundation

Important! It will take you approximately 14-20 days to build a foundation for a greenhouse, so you need to calculate the time frame before starting work.

Step 5. After the cement has hardened, the formwork can be removed. Then, using roofing felt, perform waterproofing.

Step 6. If small cavities have formed along the edges, they need to be filled with wet sand and compacted well.

Preparation of building material

Completing the preparatory work will strengthen the frame of the future greenhouse and facilitate further construction. It is likely that in the process of preparing the material you will have to remove some parts of the frames if they are broken or rotten.

Preparing old wooden windows

To give unattractive window frames a “fresh” look, you need to:

• get rid of handles and hinges that you don’t need;
• remove old layers of paint; to do this, use a grinder or a regular scraper;
• treat the structure with an antiseptic (this will protect the wood from rot, mold or small pests);
• remove all glass for safety;
• fix the windows with tape or self-tapping screws.

It is necessary to prepare the window frames taking into account the fact that the height of the walls of the planned greenhouse will reach 1.7 meters.

Flooring

Before laying the floor, it is necessary to resolve the drainage issue. Otherwise, there is a risk of water accumulating in the structure, which can lead to rot. To perform drainage, you need to dig a trench no more than 15 centimeters deep, then fill it with crushed stone or gravel. A dense layer of sand is applied on top of the gravel.

Forming beds in a greenhouse

We arrange the beds

Careful and competent design of the interior space of the greenhouse will improve it appearance. When creating passages, it is advisable to fence them off with low plastic borders. This will prevent the fertile layer of soil from getting onto the path.

To decorate the floor of greenhouse paths, in addition to concrete, the following materials are used:

• sawdust;
• wooden boards;
• porcelain stoneware;
• brick.

This variety will allow you to design the inside of the greenhouse to suit every taste.

Sawdust paths

Path made of boards

Let's consider each material separately.

Table. Materials for design of greenhouse paths.

	Excellent moisture absorption. Pleasant to the touch. Sawdust is a very cheap material.	It is difficult to move large items along sawdust paths. The material quickly spreads throughout the greenhouse. Needs regular cleaning.
Porcelain tiles	A wide variety of shapes and shades, easy care.	Installation takes a lot of time. The material is quite fragile. High price.
	The material can last for a long time. Easy to install.	Additional treatment with antiseptic agents and varnish is required. The material is large, so when working with it additional difficulties arise.
	The material is very strong and durable. Beautiful appearance of the finished path. Easy to install.	The bricks are quite heavy, so a special vehicle is needed for transportation. High cost compared to sawdust or timber. Only solid bricks will do; broken pieces will ruin the appearance of the greenhouse path.

What exactly to use as the main material for laying the floor is up to you. After selection, the material is laid on a pre-prepared bed consisting of sand and gravel.

Construction of the frame

It is recommended to use boards for this purpose. This is an excellent material with a huge number of advantages. The thickness of the boards used should not exceed 5 centimeters. The harness is built from them (its upper and lower parts).

Making the base

When creating the lower perimeter of the structure, it is advisable to lay two rows of boards - this will increase the height of the future greenhouse.

Greenhouse frame made from window frames

For vertical posts you also need to use 5 cm boards. Window frames located vertically to the ground are attached to them. Self-tapping screws are used for fixation. Polyurethane foam is suitable for treating gaps formed at the joints of structural elements. For reliability, you can strengthen the window frames from the inside using additionally installed support beams (their thickness can be less than 5 cm).

To make the structure more stable, you need to make vertical supports. They are fixed in cement mortar and attached to the posts using nails or self-tapping screws.

Vertical posts attached to the base

All holes and cracks formed during work must be treated with polyurethane foam. Pay special attention to this, since there should be no draft in the finished greenhouse. The only entrance for the outside wind is the vents that you left for ventilation.

Erection of the roof

Initially, you need to decide what type of roof you prefer - gable or single-pitch. It is worth noting that to erect a gable roof you will need much more prepared parts.

The roof is covered with plastic film

This type is considered the most suitable for all types of structures. Moreover, the material for the roof does not play a big role. Installation of a gable roof is quite simple: nail the frame blanks and cover them on top with a plastic or wooden ridge. At the same time, watch for the appearance of cracks. They will provoke the formation of an unhealthy microclimate inside the constructed greenhouse, so they all need to be sealed. The coating material used is polycarbonate or greenhouse film. Glass is the leader in quality and properties, but it is very expensive. In addition, during installation you can easily break everything.

The complete process of building a greenhouse using wooden windows

If you do not have enough material to build a roof, you can choose a lean-to type. The procedure is practically no different from the previous one, with the exception of one thing - the roof will not rise in the center, but only on one side.

The construction of a greenhouse does not require large investments; for this you just need to approach the matter wisely. And you will definitely succeed!

Construction of a mini-greenhouse

Having completed the construction of a “frame” greenhouse, you can practice a little by creating a mini version.

Preparatory stage

If, when creating a regular greenhouse, you use window frames as walls, then for mini-greenhouses the frame plays the role of a roof. Wooden planks are used to construct the walls. During the day, the roof opens to ventilate the planted plants. When calculating the size of the future building, take into account the width of the window frame. It must match the dimensions of the greenhouse. The shape of a mini-greenhouse is usually made in the form of a rectangle rather than a square. To do this, the roof is laid out from several windows.

Greenhouse made from window frames in the country

To build the frame, you will need boards. For racks, use wooden beams (4 pieces). Dig the prepared beams in the corners, and you need to build special shields from the boards. The height of the shields should be different so that precipitation can roll off the sloping roof. To do this, nail one more board on one side than on the other. Make sure that the roof fits tightly against the panels. Trim off the excess edge of the board. Secure the boards to the beams with nails.

Old windows are very practical in the household

Erection of the roof

The assembly procedure for a mini-greenhouse is simple, so there is no need to remove the glass from the window frames.

Greenhouse made from window frames

You can begin installing the roof right away.

Step 1. Position the window frames perpendicular to the long side of the greenhouse.

Step 2. Secure them to a high wall using window hinges.

Scheme of a greenhouse made from window frames

Step 3. There is no need to connect the frames together. This will allow you to ventilate the greenhouse by opening one part of the roof. All parts of the roof must fit tightly to each other.

Step 4. Screw special handles to each frame so that they (the frames) can be easily opened.

Step 5. Install the clamp on the short shield.

Step 6. Cut a special strip that you will use to support the open frame.

At this point, the construction of the mini-greenhouse is completed. You can plant seedlings there and pamper your family with fresh vegetables.

To arrange your summer cottage and build a greenhouse, you can use ready-made solutions, which are available in a sufficient variety on the market, can be used expensive materials. The true skill of a thrifty owner lies in the ability to use available resources and carry out most of the work independently, spending a minimum of money.

An inexpensive example of using scrap materials is a greenhouse made from old window frames. For successful construction, you will need the remaining frames with glass that were left over from home renovations, some knowledge and enthusiasm.

Construction stages

To fully realize your idea, you need to understand what you have to do. The procedure in most cases is as follows:

• preparatory stage;
• foundation installation;
• floor arrangement;
• construction of the frame;
• construction of walls;
• roofing device.

Having gone all the way, you will become the happy owner of a greenhouse made by yourself and will be able to independently give advice to those who want to know how to build a greenhouse from window frames on their own.

Preparatory stage

Any construction begins with a design and calculations. Before getting down to work, it’s worth looking at photographs of the most successful greenhouse models, finding finished project or make your own, draw up a drawing, calculate the amount of material required, decide on the location of the future greenhouse.

These preparatory works will make the task easier and save time in the future. The greenhouses made from window frames shown in the photo will help you make your choice.

Foundation structure

Frames with glass are quite heavy, so you can’t do without a solid foundation if you want the greenhouse to last a long time. The area needs to be cleared of debris, stumps and stones removed.

Mark the perimeter with pegs in the corners and, for convenience, tighten the rope. Then you need to prepare the locations of the supports. In the corners and along the perimeter, holes are dug every 2-3 meters, the bottom is filled with crushed stone and compacted tightly.

The depth will depend on the degree of winter freezing of the soil. These pits are needed to install the formwork support pillars.

One option is to install hollow reinforcement with wooden blocks driven into it, to which the timber will then be attached with anchors.

The supports are filled with cement mortar and left for 1-2 weeks until completely set. The final stage of constructing the foundation will be the installation of timber, which is attached to the supports and fastened in the corners in any suitable way.

Floor arrangement

When building any greenhouse, you need to take care of the microclimate, so making greenhouses from window frames requires arranging a drainage system.

At the construction stage, it is necessary to mark the locations of future beds and paths and, depending on their location, dig a drainage trench that will ensure the removal of excess moisture.

The bottom of the trench is filled with crushed stone, then sand and filled with cement. You can read about the options for the location of paths and the use of material for their design in one of the articles in the section.

Erection of frame and construction of walls

Old window frames that will form the walls of the greenhouse must first be prepared. Remove old paint, sand, remove fittings and impregnate with antiseptic solutions and varnish to maintain strength and extend service life.

Check the glass for cracks and replace it if necessary, and remove it for the period of construction work. It is quite possible to leave the windows; this will solve the ventilation problem in the future greenhouse.

Depending on the size of the structure and the availability of building material, the frame can be made of wood or metal. A wooden frame for a greenhouse will be much cheaper and easier to work with fasteners.

It is better to make corner posts from timber, and lintels and vertical posts from boards, sized according to the thickness of the window frames.

Using self-tapping screws, we attach the frames to the base and vertical posts, and then the top frame, which will form the base of the roof. We fill all the cracks, gaps and gaps with construction foam.

Roofing device

The last stage remains, and the greenhouse made from window frames with your own hands is almost ready. The greenhouse roof can be made from the same window frames or using polycarbonate film.

The main condition during construction is to provide a slope for water drainage and snow removal.

When making a roof from a film, a thin sheathing is installed and the polycarbonate is stretched tightly.

If window frames are used in construction, you can make a roof with two slopes or a single slope.

Further arrangement of the greenhouse may include various options for equipping with drainage systems, drip irrigation and air conditioning, lighting and heating.

To give a finished appearance, the greenhouse can be painted and decorated to your taste.

Photo of a greenhouse made from window frames

A spacious, “growth” greenhouse for growing early vegetables and seedlings is the dream of every gardener. Unfortunately, most often this desire does not coincide with the financial capabilities of the owners suburban areas - high prices on factory products, as well as the cost of building materials, can cool the ardor of even the most avid summer residents. To avoid unnecessary expenses and get a reliable and durable structure, just pay attention to old window frames - an excellent solution for making a greenhouse with your own hands.

Window frames as a building material: pros and cons

What home craftsmen come up with, breathing a second life into seemingly useless and unnecessary things. Today it is impossible to say who first came up with the idea of ​​building a greenhouse from used window frames, but the genius and simplicity of this solution deserves respect and admiration. Old windows are an almost ideal option, because they have a number of advantages over other building materials:

• tightness ensured design features frame;
• high degree of light transmission due to the large glazing area;
• mechanical strength;
• rigidity;
• the presence of vents for ventilation;
• installation speed;
• the possibility of building a greenhouse without the involvement of assistants;
• ease of repair in case of damage;
• low cost.

The demand for plastic windows simplifies the search for material for building a greenhouse

Although the use of window frames has so many undeniable advantages, this material should not be idealized. The weight of a wooden frame is, in fact, small, but when assembled with glass, the structure becomes heavy and requires arrangement solid foundation- otherwise, ground movement may cause the structure to shift and damage the glass. Over time, the joints between individual elements dry out and require sealing, and the wood itself needs protection from the harmful effects of a warm and humid environment, so you need to be prepared for minor repair work at the beginning of each season. However, these shortcomings are not so significant as to refuse such a simple and accessible way construction.

Design and design features

Like other similar structures, a greenhouse made from old windows is installed on a solid wooden or concrete base. The choice of foundation depends entirely on the frequency of use of the structure, the structure of the soil, the topography of the site and other natural factors. On strong earthen soils, it is sufficient to use 50–60 mm thick hardwood boards as support, while sandy or sandy loam soil, as well as the risk of flooding by groundwater, will require thorough concrete work.

In some cases, without durable concrete base not enough

Of course, individual window frames can be attached directly to each other, but in order to obtain a strong, reliable structure, you must first assemble a frame from wooden slats with a cross-section of at least 50x30 mm. This solution will significantly increase the rigidity of the structure, which means that the risk of damage to windows when frames are deformed during installation and during operation will be reduced. Another factor in favor of a wooden frame is the ease of installation of doors and a significant simplification of the roof structure, so it is not worth giving up a solid frame in order to save money - in the future this decision will justify itself many times over.

Greenhouse frame construction from used windows

Some home craftsmen also use window frames as roofing material, arguing that the light transmission of the greenhouse increases and the structure becomes truly monolithic. However, this is not recommended for several reasons:

• moisture flowing into cracks and gaps between the glass provokes increased rotting of the wood;
• possibility of roof damage from hail;
• low structural stability under snow load;
• an increase in roof mass reduces the stability of the greenhouse;
• It is impossible to predict how old window frames will behave over time, so such a roof is considered potentially dangerous.

At the same time, for the construction of not a greenhouse, but a greenhouse, the use of window frames as roofing material is more convenient and practical.

One of the greenhouse options for a suburban area

An important issue that should be decided at the design stage is the type of roof. Gable or arched structures, although more complex, resist winter drifts very well - snow rolls perfectly along their inclined surfaces. Concerning pitched roof, then it is much easier to install and requires less building materials, but you will have to pay for this by reducing the reliability of the structure.

An arched roof copes best with snow and rain

To connect individual frames and building elements to each other, you can use furniture corners and metal strips, which are fastened with self-tapping screws. Of course, preference should be given to parts made of galvanized metal - we should not forget about high humidity, which provokes rapid corrosion of fasteners.

Corners and metal perforated strips from the nearest building materials store are suitable for attaching window frames.

Most likely, the frames intended for the construction of a greenhouse will differ in size. To simplify the work, you will need to take the dimensions of the windows and number them, and then make a small sketch indicating the sizes and installation locations of individual mounting blocks. Of course, it is better to use windows of the same height - in this case it will be easier to install them, and the greenhouse will turn out not only even and symmetrical, but also beautiful.

When drawing up a working drawing, be sure to take into account the recommended sizes of beds and passages between them

The length of the structure can be any - it all depends on personal preferences, availability of space and building materials. But when calculating the width, it is necessary to take into account the location and number of beds, as well as the paths between them. To make it convenient to work in the greenhouse, its passages are taken equal to 0.5 m - this will allow you to move around with a small wheelbarrow. The width of the beds must be at least 1 m, otherwise the plants will not have enough space for normal growth.

Tip: a larger greenhouse can be built from the same amount of material if it is built as an extension to one of the outbuildings located on the site.

Getting ready for construction

At the very first stage, a place for a greenhouse is selected, the site is cleared, and building materials and tools are prepared.

Choosing a place

The success of the entire event depends on how correctly the location for future construction is chosen. Firstly, the structure should be illuminated for as long as possible sun rays, so shaded areas near tall buildings or trees should not be considered. Secondly, it is better to install the greenhouse in places with minimal movement of atmospheric layers - reducing the wind load affects the stability of the structure and reduces heat losses. Thirdly, the fertility and condition of the soil must be taken into account. On bulk and unstable soils, it will be necessary to build a columnar or strip foundation, otherwise the walls will warp and the glass in the frames will crack.

The construction site should not be located in lowlands. Even if it is possible to avoid flooding or silting of the beds, the high groundwater level will have a detrimental effect on the plants.

Before starting to arrange the foundation for the greenhouse, stumps are removed at the construction site, the area is cleared of debris, and cleared of weeds and bushes.

Scheme for choosing a location for installing a greenhouse or greenhouse

What you need to build a greenhouse

Depending on the chosen greenhouse design, in addition to the window frames themselves, the following materials will be needed for construction:

• roofing felt;
• sand and crushed stone;
• cement;
• steel pipes with a diameter of at least 100 mm;
• hardwood boards 50–60 mm thick;
• timber 50x50 mm;
• slats 20x40 mm;
• metal corners;
• self-tapping screws;
• polyurethane foam;
• polyethylene film or polycarbonate sheets;
• protective and antiseptic agents for wood processing.

You can’t do without polyurethane foam when building a greenhouse from window frames - it reliably seals all joints and gaps

It is better to prepare the tools in advance, otherwise the process of pleasant creation may turn into a tedious search. Here's what you might need while working:

• angle grinder (“grinder”) with cutting disc for metal work;
• sledgehammer;
• shovel and bayonet;
• containers or stretchers for carrying bulk materials;
• wood hacksaw;
• a set of screwdrivers or a screwdriver;
• hammer;
• drill with a set of drills for wood and metal;
• roulette;
• building level;
• pencil.

If you plan to install the greenhouse on a solid foundation, then you should take care in advance about how the concrete solution will be prepared - you will need a metal vat or a concrete mixer.

Preparing window frames

To build a spacious greenhouse you will need a lot of window frames, so it is better to look for materials for construction in advance. Of course, you can ask friends and acquaintances about their availability, but it is best to look through newspapers for free advertisements or contact one of the companies that install plastic double-glazed windows - where you can buy old windows for a nominal fee.

You can use a hair dryer to remove old paint.

Before starting construction, future Wall panels should be prepared. This will increase their service life and make the structure more attractive. To tidy up old window frames, you need to:

• dismantle fasteners and fittings (handles, latches, latches, hinges, etc.);
• with help grinding machine or scrapers to remove any remaining old paint. In some cases, you can use a special remover, for example, the compositions “Antikras-Sprint”, “Zebra SP-6”, “Household” and others;
• treat the frames with antiseptic agents that can protect the wood from fungi and insects;
• Secure unused windows with self-tapping screws. Gaps on mating surfaces should be repaired using sealant or putty.

Some online resources suggest exposing glass from frames, arguing that it may be damaged during installation. We do not recommend doing this under any circumstances. Most likely, the glass will require replacement just after unsuccessful dismantling, especially if during its installation wooden glazing beads were used, mounted on ordinary enamel or oil paint.

Step-by-step instructions for building a lean-to greenhouse from window frames with your own hands (without a foundation)

We offer you an algorithm for building a spacious greenhouse from old window frames. Its installation does not require a solid concrete foundation, so installation can be completed within two weekends. The structure has a pitched roof and is distinguished by its simple and undemanding design - any home craftsman can replicate it.

Base installation

A properly arranged wooden base will last at least 10 years only if certain conditions for its protection are met. Otherwise, the wood will rot much faster - a humid environment and contact with soil do not contribute to the safety of the boards.

So, you will need a beam with a cross-section of at least 100x100 mm made of larch, oak, acacia and other sustainable types of wood. It must be treated with several layers of antiseptic agents and then tarred.

The place where the base will be laid must be prepared in advance. To do this, a trench up to 20 cm deep is dug along the perimeter of the structure, in which a sand and crushed stone cushion is installed. The drainage layer will remove excess moisture and promote durability wooden base. To achieve its maximum durability, the trench is covered with a layer of roofing material and only after that the timber is laid.

The wooden base of the greenhouse is protected from moisture in any available way.

The individual elements are fastened together end-to-end using metal strips and corners, as well as using the “half-tree” method. To do this, indentations are made on the mating parts using a saw, hammer and chisel, after which they are connected to each other using nails or self-tapping screws. As a rule, additional fastening of the base to the ground is not required - the mass of the window frames will be enough for the structure to successfully withstand the wind. However, to be on the safe side inside Each corner can be driven into the ground with sections of pipes 0.5–0.6 m long, attaching them to the beam using metal strips.

One of the ways to attach a wooden greenhouse base

For significant differences in height, as well as in lowlands, a columnar foundation is used. It is equipped using metal pipes large diameter or by pouring concrete blocks. The boards laid on such posts are secured with dowels or metal corners, and the gap between the base and the surface of the area is covered with clay and carefully compacted.

Walling

The assembly of the greenhouse begins with the construction of the frame. To do this, a lower frame made of timber is laid on the base. You can use any type of lumber, it is important that their cross-section approximately matches the thickness of the frames. Most often, they take inexpensive pine beams with a cross-section of 50x50 mm, the individual elements of which are fastened with furniture corners or the “half-tree” method.

The frame of the greenhouse made of window frames includes vertical posts and horizontal lower and upper trim

Vertical posts are installed at the corners of the frame, as well as every 2–3 m (the distance depends on the width of the window frames). Their length is chosen taking into account the height of the windows, as well as focusing on one’s own height - it must be comfortable in the greenhouse, otherwise work “for the soul” will turn into punishment. The greenhouse has a pitched roof, so the posts on one side should be 0.5–1 m higher - this will provide the roof with the required slope.

For small greenhouse vertical posts installed at the corners of the structure will be sufficient

At one end of the greenhouse, vertical posts are installed so that the resulting opening can serve as a door frame. Perhaps the width of the structure will not be enough to cover the remaining space with window frames. In this case, the space between the door and corner posts covered with plastic film.

From above, the vertical structural elements are connected to each other by horizontal strapping using the same self-tapping screws and metal corners. Unlike greenhouses covered with plastic film, structures with walls made of windows do not require reinforcement of the frame. The structure will acquire the necessary rigidity after the wooden frames are installed in place. However, there is no need to rush to install them - you should first make the roof.

Frame assembly

Roof arrangement

The construction of a pitched roof for permanent structures is shown in the figure. In our case, there is no need to install additional racks and rafter legs - they, like ceiling beams, will be needed only in greenhouses more than 6 meters wide. In the greenhouse under consideration, the roof support in the lower part is the upper frame frame, so all that is needed is to attach the timber to the ends of the long posts and install the rafters. The best material for them it is not timber, but a board installed “on edge” measuring 50x100 mm. It will not allow the roof to sag even with a significant snow load.

Shed roof design

If the greenhouse will be covered with film, then the rafters should be sanded and then covered with fabric or foam rubber. They will protect the roofing material from damage.

The rafter legs are mounted to the horizontal frame in the places where the racks are installed, at a distance of no more than 1 m from each other. For fastening polycarbonate sheets 20 mm thick slats can be laid perpendicular to the rafters, while polyethylene film does not require additional sheathing.

One of the ways to attach a rafter leg

We have already said above that it is not recommended to use window frames as a roof - film or polycarbonate is much safer, and they are also easier to install. When choosing polyethylene fabric, preference is given to heat-stabilized materials - they are practically not susceptible to the destructive effects of ultraviolet radiation. The best option is considered to be a special reinforced film for greenhouses. As a rule, such coverage is enough for 2-3 seasons.

It is convenient to use thin slats or window beads to attach the film.

Mount roll material with a little tension, so this work is best done together with a partner. To attach the film, wooden planks are used - they provide sufficient pressure and prevent damage to the polyethylene. An overlap is made on both sides of the greenhouse, which will be sufficient to eliminate the gaps between the frame framing and the longitudinal beams of the roof. The gable openings are also covered with polyethylene or triangular polycarbonate panels. By the way, the latter option is more preferable due to its durability - it will not be necessary to renew the coating for many years.

Fixing window frames and installing doors

After constructing the frame and roof, they begin to install the window frames, checking with the previously developed drawing. The windows are installed on the outside of the frame, after which they are fixed to the beams and to each other using nails, self-tapping screws, furniture corners and perforated metal strips. During installation, the frames are oriented so that the windows open outward. Excessive vibration that occurs during nailing of frames to the frame threatens to crack the glass. To reduce the impact load, through drilling is performed in the right places. Their diameter should be 0.5–1 mm smaller than that of the nails used - a slight tension will only benefit the connections.

The gaps between the individual elements of the greenhouse are filled with polyurethane foam. After hardening, excess polyurethane sealant is cut off flush with the frames, after which it is plastered or covered with thin wooden planks. This will protect the sealing layer from the harmful effects of ultraviolet radiation and excess moisture.

A greenhouse made from old window frames is ready for use.

The door frame is made of wooden beams and attached to the frame using ordinary metal hinges so that the door opens towards itself when visiting the greenhouse. Considering the increased operational load, it is better to sew up the sashes not with film, but with a polycarbonate sheet. When building a large greenhouse, you can use a ready-made balcony door. Of course, in this case doorjamb must be reinforced, so it is made from a 50x100 mm board with a selected quarter.

Latch bolts and stops are installed on the door and vents, which will allow them to be held in the open position to ventilate the interior space.

The success of a mini-greenhouse farm will depend both on the quality of the structure itself and on its internal contents. A properly equipped greenhouse will make it possible to work easily and comfortably, while maintaining a positive mood. And this, as you know, is half the success in any business.

One of the most important stages in the construction of a greenhouse is the construction of beds. If the site is located on fertile soil and is not subject to flooding, then it is enough to install fences and pour a mixture of humus, peat and black soil inside. If there is a danger of flooding, as well as in places with high level groundwater, paths and beds are made only after drainage is installed on the floor.

Arranging beds in a greenhouse

For these purposes, soil is removed to a depth of 20 cm, after which the floor is covered with a 10-centimeter layer of fine crushed stone or granite screenings. The remaining space is filled with sand and compacted thoroughly. After this, the beds are formed by installing a border strip or strips of flat slate along their perimeter, creating frames from boards or making brickwork. The internal space is filled with a fertile mixture. Its thickness must be sufficient for growing selected garden crops, so this parameter is not standardized. For some, a layer of 20–30 cm is enough, while others prefer not to bend over, creating so-called raised beds up to 70–90 cm high.

The paths inside the greenhouse can be covered with crushed stone or sawdust - this will effectively remove moisture. The disadvantage of such a coating is that it creates difficulties when moving greenhouse equipment and complicates cleaning. It is best to spend a little money and lay out the paths with paving slabs, concrete or make a boardwalk. In the latter case, oak logs and hardwood boards are used. Before laying, the supporting elements of the structure must be tarred, and the platform itself must be treated with an antiseptic and coated with oil paint.

In a properly equipped greenhouse, work is a pleasure

In order for the greenhouse to be not only a functional unit, but also have a finished appearance, everything wooden parts should be painted inside and out. This will not only make the structure more attractive, but will also make it more durable.

Video: features of building a greenhouse from old windows

Building a greenhouse from old window frames is not difficult at all. For this you will not need either expensive materials or a specific tool - only your desire and imagination. By equipping it with a drip irrigation system, installing heating and lighting, you can achieve excellent results in growing early garden crops and get fresh vegetables on the table at any time of the year.

How to make a greenhouse with your own hands from old window frames?

The short summer season is sometimes accompanied by cool weather and prolonged rains. However, the desire to receive good harvest, regardless climatic conditions, is preserved by all summer residents. . A properly organized greenhouse is able to accumulate heat and maintain the desired microclimate inside the space.

Some people turn to specialists in this matter to create a greenhouse, others boldly get down to business and build the structure with their own hands. When performing work independently, other technologies are also used. However, such a greenhouse made from old frames is considered the most simple option, it is quite simple to build. Due to its properties, glass is better suited than film for a greenhouse with vegetable crops. It not only allows the sun's rays to better penetrate the greenhouse, but also keeps it inside longer.

Important points during construction

Let's look at some details that are important to know in order to build a greenhouse from old wooden beams Right:

• In addition to a suitable place for construction on a summer cottage, the dimensions of the greenhouse also determine the size of the existing old window frames;
• If you need reliable design, which is designed for long-term operation, it is better to make the frame of the greenhouse permanent. An excellent option for creating a solid foundation would be brickwork. The roof for the greenhouse can be made as a separate removable element, which is dismantled during winter and snow loads. If the brick version for the frame does not suit you, you can build a base using boards;
• When building a greenhouse from unnecessary old windows, the upper part of the frame can be made with one or two slopes. To tilt the roof in both directions, you must first lay a ridge beam in the middle. If a lean-to greenhouse is planned, its location should allow for maximum sun exposure during the day. This condition will have a beneficial effect on the condition of the plants;
• If there are a lot of old windows, it is better to make the entire frame entirely from them, because such greenhouses from frames let in much more light, promoting the active development of vegetable crops during the growth period. However, you need to be careful not to damage the integrity of the mounted glass in the side part;
• Do not forget that your structure must be airtight. In addition to the fact that assembling a greenhouse requires care and precision, you also need to take care to eliminate gaps between the elements. You can fill the seams yourself using sealants and special putties. The better the space is isolated from the inside, the better for the plants;
• Provide several supports that can support window frames while you need to work in the greenhouse, caring for vegetable crops;
• Choose a place for a greenhouse made from old window elements that is as windless as possible. It is desirable that a water supply be provided to the building for convenient watering. An excellent option is to build a greenhouse by connecting it to another existing capital structure;
• If the frame is made of wood, take care to protect the structure from rotting. Before installing the frame, you must first distribute roofing felt around the perimeter, and impregnate the lower part of the supporting structure of boards with resin. If these measures are observed, the base of the greenhouse made of window elements will last a long time;
• In order for the service life of a greenhouse made from old wooden beams to be impressive, it is better to build a brick base to support the frame.

Consistent actions during the construction of a structure

Preparatory stage:

• Measure all the window frames you have. Most often, the elements of old frames differ from each other in size;
• Knowing the dimensions, you can understand which option for distributing elements along the frame is the most optimal. If all the elements for the greenhouse are the same, the difficulties in their distribution will be minimal;
• Record your decision after the calculations in the drawing, at least schematically. This way, you don't have to do the same work several times, remembering the final version. On the drawing, fix the entrance door and the places allocated for the beds, mark the distances between them. Don't forget to make handles later. .

Determining the optimal location

You need to be very careful when choosing a location, since proper placement of a greenhouse on a site is one of the main components of a successful harvest. In order for the sun to warm the soil of the greenhouse from the window frames for as long as possible, choose an area near which there will be no tall bushes and trees. It is also advisable to move away from buildings on the site that cast an impressive shadow. The area under the greenhouse must be protected from drafts caused by the wind.

The plot of land for the greenhouse must be level. The reference point for placing the structure is from north to south. Choose loose soil for installing the greenhouse. Avoid proximity to groundwater when placing the structure; it is better that the soil is moderately dry.

We install the base with our own hands

It is quite simple to build a foundation for a greenhouse from old frames, since this structure does not create much pressure on the base. The foundation can be strip; for this, a depression is made in the ground around the perimeter of the greenhouse and filled with concrete mixture. The base is also made of brick and wood. Brick and concrete options are more durable.

There is a base made of metal; it is also used for the frame of the greenhouse from window elements. Such a foundation is mounted strictly under the support pillars.

– this corresponds to the level. Monitor this parameter with a special device.

Preparing window frames

This stage involves dismantling unnecessary parts from frame elements: fasteners, hinges, window handles, etc. Next, sand the surface of the frames, removing the old layer of paint. Subject to these conditions, new paint will be distributed evenly and form a reliable protective layer that prevents the process of decay. Additional treatment of wood against rodents will not be an unnecessary undertaking.

We mount the frame with our own hands

Before installing wooden window frames, it is necessary to build a frame for the future greenhouse. Its construction is not particularly difficult; you must be guided by the dimensions of the drawing when preparing bars of the required size. The elements are assembled together using special screws and nails.

Fastening elements to the frame structure

In order for the structure to be stable and last for many years, it is better to install the frames using screws and self-tapping screws. These fasteners are no more reliable than nails, however, they can reduce the likelihood of glass damage. We seal the space between the elements with sealants or foam, depending on the size of the gaps. Thus, the necessary conditions for the tightness of the space will be met in the greenhouse.

Roof structure

The best option is considered to be a gable roof with a ridge beam arranged along the greenhouse. . It is better not to use the material for the greenhouse roof; choose a lighter material. Great solution the roof will be made of polycarbonate, its cost per square footage of the upper part of the greenhouse structure is quite acceptable.
