How to install a plastic window with your own hands. Technology for self-installation of PVC windows How to install a plastic window yourself

Rice. No. 4

Mounting wedges are installed under all vertical elements of the window frame - these are vertical trims and vertical imposts. Distance (side) blocks are installed at a distance of about 200 - 250 mm from the corners of the window frame; the dimensions of the side blocks are selected similar to the dimensions of the lower support blocks. Installing spacer blocks in the very corners of the window frame is unacceptable, since the blocks will prevent thermal deformation of the window during seasonal and daily changes in the air temperature and the window itself.

10. Aligning the window block frame vertically and horizontally, temporarily fixing it in the required position

The frame of the window structure, together with the tapes glued to it, is placed in the opening and, using plastic wedges, is aligned vertically and horizontally and is pre-fixed.

11. Final fixation of the window block frame in the opening

Holes for fastening elements are drilled in the wall. The frame of the window structure is finally fixed to the wall with fasteners. When installing fasteners, be careful that the box is not stretched by the fasteners!

12. Gluing tapes at the bottom of the window structure

Carefully remove any dust generated when drilling holes in the wall. Prime those areas of the opening surfaces to which the tapes will be glued. Wait for the primer to dry. Vapor barrier tape “ROBIBAND VM V 100” is glued to the lower surface of the opening. When gluing, the tape should be directed towards the room. The length of the tape piece must be sufficient to cover the entire length of the lower horizontal assembly seam, taking into account the formation of overlaps or edges at the corners for reliable sealing of the corners. “ROBIBAND NL 120” tape is glued to the outer plane of the stand profile or the outer plane of the rebate intended for installing the drip lining with a narrow adhesive strip. When gluing the tape, it should be directed towards the street. The length of the tape segment must be sufficient to cover the entire length of the lower horizontal gap, taking into account the formation of laps or edges at the corners for reliable sealing of the corners.

13. Filling installation seams with polyurethane foam insulation

A container of polyurethane insulation (PPU) is prepared for use in accordance with the instructions for use of the specific foam. It is recommended to use polyurethane foam with high initial and low secondary expansion. Before filling the installation gap with polyurethane foam, it is necessary to moisten the surfaces of the installation gap with water by spraying. Do not wet the areas of surfaces to which the tape will stick, as nothing will stick to a wet surface! After moistening, the installation gaps are filled with polyurethane foam. The degree of filling the gap depends on the degree of expansion of a particular PU foam. Test releases are recommended. The amount of polyurethane foam in the seam should be enough so that the polyurethane foam, when it expands, pulls the tape, but does not tear it off.

Before gluing tapes onto wet foam, re-wet the surface of the foam, since otherwise large voids may form in the foam!

14. Gluing “ROBIBAND VM” tapes to the opening

The protective paper is gradually removed from the adhesive strip of the vapor barrier tape “ROBIBAND VM 120”, glued to the vertical and upper horizontal sections of the window frame, and the tape is glued to the surface of the window opening. Make sure that when gluing the mounting foam does not get between the tape and the surface of the opening. The protective paper is removed from the “ROBIBAND VM 100” vapor barrier tape located in the lower part of the opening, and the tape is glued to the front plane of the stand profile or to the front plane of the rebate intended for installing the window sill. Edges (sides) are formed in the corners of the opening to reliably protect the joint. The protective paper is removed from the “ROBIBAND NL 120” tape, and the tape is glued to the bottom of the window opening. Edges (sides) are formed in the corners of the opening to reliably protect the joint.

15. Installation of ebb and window sill

A sill and a window sill are installed on the window block. All operations must be performed carefully to avoid displacement of the window frame.

16. Hanging sashes and installing fixed glazing

The sashes are hung and fixed glazing is installed. The doors close. All operations must be performed very carefully to avoid the frame of the window structure from moving.

17. Quality control

Quality control is carried out after 24 hours. Quality control consists of checking the tightness of the tapes along the entire perimeter of the installation seam, both from the indoor and outdoor sides. If the tape is glued tightly, without peeling or gaps, then we can assume that the installation was done efficiently.

The PSUL tape should expand and completely cover the gap.

18. Finishing slopes

The finishing of the slopes is carried out in accordance with the adopted constructive and design decisions.

Plastic windows deservedly enjoy a reputation for functional, reliable, durable and aesthetic designs. They are becoming more and more popular and are confidently replacing the wooden windows that are familiar to many people.

Plastic windows have gained a reputation as strong, durable and reliable structures.

Their additional advantages include the fact that, with a strong desire, almost anyone can install plastic windows themselves. And this is a big plus, because... For installation, specialists ask quite a lot of money. In addition, having figured out how to install a plastic window, you will independently control the entire process and will be able to do everything in accordance with technology.

How to determine the size of a future plastic window

Before ordering plastic windows, you need to figure out what exactly the design should be. And this preparatory stage begins with taking measurements. When taking measurements independently, the home master should know that there are window openings without and with a quarter. The order in which two different types of openings are measured will also differ.

The quarter option involves taking measurements in the following order. First you need to measure the opening between the quarters at the narrowest point and add 3-4 cm to the resulting value. This will be the width of the structure. Additionally, make sure that the specified width of the future plastic window exceeds the largest distance between the vertical quarters. To determine the height of the future window, measure the distance between the bottom plane of the opening and the top horizontal quarter. This way you will determine the amount you need.

In the case when a plastic window is installed in an opening without the above-mentioned quarter, to determine the appropriate size, you simply need to subtract 5 cm from the height, and 3 cm from the width.

Additionally, determine what size the window sill and flashing should be if you plan to replace them. There should be no complications with this operation, you just need to consider the following important factors.

When determining the width of the ebb, future thermal insulation or cladding must be taken into account. According to the standards, the ebb should protrude from the vertical wall by 5-10 cm. The width of the window sill is calculated taking into account its future functional purpose. For example, if you want to install potted flowers on it, it is better to order a wider design. In most cases, when selecting a window sill, the calculation is carried out so that the free part of this element covers the heating radiators.

The length of the window sill should be 8-10 cm greater than the width of the opening. The edges must be recessed into the slope cavity by at least 5 cm.

Ordering a window and preparing for work

At the next stage, you need to go along with the obtained measurements to a company specializing in the production of plastic windows. By the way, if you don’t want to waste time on measurements or doubt that you can do everything correctly, order this service from the same company. Most companies offer it free of charge, provided that the window is ordered from them.

In addition to the window size, you need to determine the following parameters:

1. The number of cameras in a double-glazed window.
2. Number of cameras in the window profile.
3. Availability of fittings and necessary fasteners.

The consultant will tell you in detail about the features of each option. You can prepare in advance. So, if winters in your region are not very cold, and the street outside the window is not very noisy, a window with two glasses and a profile 60 mm wide will be quite sufficient. Next, focus on the climate and environment.

To install a plastic window yourself, you will need the following:

To install windows you will need: a hammer, a drill, a screwdriver, a building level, etc.

1. A gun for polyurethane foam and the foam itself.
2. Drill with variable speed control and perforation mode.
3. Small ax and hammer.
4. Metal scissors.
5. A sharp knife, a stationery knife will do.
6. Building level.
7. Chisel.
8. Sander.
9. Nail puller.
10. Jigsaw. If you don't have one, you can use a hacksaw with fine teeth.
11. Putty knife.

Additional materials you can buy:

1. Multi-purpose construction adhesive.
2. Wooden beam with a total length of 150-200 cm and dimensions of 2x4 cm.
3. Dowels.
4. Plastic corners and panels made of the same material.
5. Self-tapping screws of different sizes. Typically used are 6x40, 2x16, 2x80.
6. Solvents.
7. Mix for plaster.
8. Silicate glue.

Do-it-yourself dismantling of an old window

At the very initial stage of changing windows, it is necessary to dismantle the old window structure.

If there are already windows installed in the room, then before you begin installing a new window, you need to get rid of the existing structure. If you don’t plan to install the old window anywhere in the future, you don’t have to try to be careful, but caution won’t hurt. Do everything possible to avoid getting hurt or dropping the window outside. The last rule is especially relevant for apartments in multi-storey buildings, because a window could fall on someone or damage someone else's property. And even in a private house, cleaning glass will not give you any pleasure.

First, remove the opening windows and sashes. Remove all glass from the structure, first removing the retaining beads. Take a grinder with a concrete wheel or a hacksaw. Using the tool, make cuts along the horizontal and vertical elements of the window frame.

Using available tools - a pry bar, a crowbar, or a hammer - remove the product from the opening. In some cases, when the owner wants to preserve the old window, the structure can be removed without deformation or damage. But this will require much more time and certain skills.

At this stage, both the external ebb and the window sill are dismantled. At the end, the window opening is thoroughly cleaned of dust and all kinds of construction debris.

Step-by-step instructions for installing a plastic window

Gradually you have come to the main stage of the work - installing a new window. This work requires careful and consistent implementation of a whole list of various activities.

First, the window is prepared for further installation. At this stage, you need to attach mounting plates to the end of the top and sides of the frame. In the future, it is thanks to them that the structure will be held in the required position. Quite often, installers replace plates with hangers, which are usually used when installing various plasterboard structures. But when installing a plastic window, it is much more advisable to use plates. They are stronger than pendants.

The planks must be securely fixed to the end of the frame. During installation, the fasteners will need to fit into the body of the metal profile of the block. And this should be done in such a way that the glass unit does not deform. Fastening is done using self-tapping screws. Select the diameter of these products taking into account the size of the window. Standard-sized structures are usually installed using self-tapping screws with a diameter of 4 mm. For larger blocks (from 2x2 m), it is best to use larger self-tapping screws - 5-6 mm in diameter.

Attaching the anchor strips to the end of the frame should be done so that they are installed in increments of 6-8 cm at a distance of 10-15 cm from the corners of the product.

After this, you need to correctly position the prepared window structure. At a superficial glance, this procedure may seem quite simple, but take it seriously. It is best to enlist the help of an assistant at this stage. One of you will support the block, and the other will level it.

Place the block in the opening and adjust its position using pre-prepared wedges. It is important to position the block strictly vertically and horizontally. At this stage, follow the recommendations:

1. Wedge the module not only from below, but also from the sides.
2. Make sure that all vertical frame elements are in the same plane.
3. If there is an impost, place wedges under it as well.

Check that the unit is installed evenly using a level. If there are the slightest deviations, correct them. And only after that proceed to fixing the module. To do this, use anchor bolts or dowels to fix the anchor plates to the opening cavity. It is important that the elements are attached strictly to the enclosing structures. To do this, it may be necessary to remove a layer of plaster where the anchor plates are attached.

After you securely fix the module, seal the seams using foam specially designed for this job. It is important that the material is intended specifically for the installation of plastic windows. Carefully read the instructions and make sure that it can be used at the humidity and temperature where the module is installed.

Before applying foam, moisten the joint surface with water. If you need to fill an area wider than 3 cm, do it in 2 stages with a half-hour break.

Relatively recently, all residential buildings had ordinary wooden windows, which had to be sealed for the winter. Today it is almost a relic of the past. And most people strive to replace such windows with modern plastic window structures, and they are especially interested in installing plastic windows with their own hands.

This desire of the consumer is quite understandable - plastic windows not only have an aesthetic appearance, but also serve as interior decoration. They are also much easier to use, last an order of magnitude longer, and are significantly cheaper than their wooden counterparts.

If you have a desire to replace the old windows in your apartment with modern double-glazed windows, then you will certainly ask yourself whether it is possible to install a plastic window yourself. How difficult is it to install plastic windows, and can you do it yourself without the help of specialists?

Yes, it's quite possible. In order to install a plastic window with your own hands, it is not necessary to have a construction specialty. With certain skills and good tools, anyone can install a plastic window with their own hands.

Let's figure out how to do it right.

What does a plastic window consist of?

First, let's look at the design of a plastic window. Without this, you will not understand the installation process itself.

Plastic windows are made from a special material called PolyVinyl Chloride. That’s why plastic windows are called PVC windows in short. Like any window, the main element of a PVC window is a frame made of a profile consisting of cells. The more such cells in the frame (also called chambers), the warmer the window will be.

Typically the frame color is white. Although plastic can be black, brown, and even colored. The most common and most budget option is white plastic windows.

In addition, the window consists of an opening part (sash) and a stationary part, which is called a “capercaillie”. The glass unit is directly inserted into these parts of the window, which is pressed against the frame with a special plastic strip. For tightness, a black rubber seal is placed.

Special mechanisms are installed on the window sashes, with the help of which the window opens and closes.

In addition, on the outside the window has a so-called ebb - a small board with the help of which precipitation is removed, and slopes - plates that seal the side and top parts from the street side.

Stages of installing plastic windows with your own hands

All stages of installing plastic windows with your own hands come down to the following:

• careful measurements;
• dismantling old window structures;
• preparation of window openings;
• DIY PVC window installation.

Taking measurements

Before ordering and, accordingly, installing a plastic window, you need to make several measurements. Moreover, how carefully they are done will determine how your structure will fit into the window opening. Remember that accurate measurements are almost half the battle. If you take the measurements incorrectly, when installing plastic windows yourself, the structure simply will not fit into the opening. In addition, the windows may begin to freeze.

First you need to carefully examine the opening. If the part of the window that is smaller on the outside, then measurements are taken at the narrowest point. Moreover, it is highly advisable to make several of them, because window openings are rarely perfectly smooth. Find the smallest measurement value and add 3 to it. Measure the height, leave its value as it is.

If the window is the same size both inside and outside, measurements are taken slightly differently. You need to measure the width and height. Then you need to subtract 5 cm from the height, and 3 from the width. This will be the full size of your window, with width and height. We subtract the values ​​in order to leave gaps for installing the window sill and special mounting foam.

Each owner chooses the window sill according to the size he wants. Some like wide window sills, some like narrow ones, and some make them at wall level. This is individual, and there are no rules here. This applies to width.

The length of both the window sill and the ebb should be taken with a margin - about 10 cm wider than the window opening.

Getting ready for installation

Do-it-yourself installation of plastic windows always begins with dismantling the old window. As a rule, even novice builders find dismantling particularly easy.

After you have broken out the old window, you need to carefully inspect the opening and remove anything that may fall off later. If some parts of the opening protrude from the walls after dismantling, they must also be removed and the surfaces smoothed. Potholes, if any. It should be sealed with cement mortar.

When installing PVC windows with your own hands, you must take into account the following circumstances:

• the plastic window structure should be carefully secured;
• the window structure must be leveled both horizontally and vertically, otherwise in the future it may simply warp;
• It is necessary to plaster the mounting foam on all sides, with which the structure is attached, also in order to avoid future problems such as deformation.

Plastic window installation technology

Install a plastic window with your own hands as follows:

• The structure should be fixed on four sides using wedges, and it should be determined how accurately the frame is positioned relative to the opening;
• secure the frame with special bolts;
• attach the structure with screws to the wooden part;
• seal the plastic structure using polyurethane foam, spreading it over a surface slightly moistened with water.

You need to start with the fact that there are two different ways to install plastic windows with your own hands.

The first method is to drill holes in the window frame for special anchors, which are driven into the wall. This is a rather complicated method, but a more reliable fastening.

The second method is that metal plates are first attached to the frame from the outside, and only then these plates are attached to the walls. This is a much simpler and faster method, but such fastening is not reliable. The frame can simply warp even in strong winds. Therefore, if you nevertheless decide to make your life easier and install a plastic window with your own hands using the second method, use thick and wide metal plates. In this case, you can give your plastic structure greater reliability. However, if your city is very windy, this method is definitely not suitable for you.

Direct installation

Installing a plastic window with your own hands using the first method with reliable fastening is carried out as follows.

First, you should check whether the structure and the window opening are compatible. If everything is in order, we proceed directly to installation.

First you need to remove the window sash. For this:

• turn the window handle down, placing the window in the “closed” position, and use a screwdriver to remove the trim from the hinges;
• pull out the pin, which is located on the top hinge;
• open the shutter by turning the window handle to a horizontal position, after which, by lifting the window sash, you can easily remove it from the lower pin.

After you have removed the sash, you need to remove the double-glazed window on the capecaillie. For this:

• insert a small spatula or something similar, strong enough, thin and not wide, into the gap between the frame and the bead;
• move the glazing bead with a spatula, going along the entire length, and remove it from the frame.

After this, you can easily remove the glass unit itself. The main thing is that it does not fall out of the frame after the glazing beads you removed are no longer holding it. To avoid this, the window should be tilted.

The frame is freed from the glass unit, and now it should be covered around the perimeter with special tape. This tape is needed to keep the window warm.

As a rule, white self-adhesive protective tapes are glued to the frames. It is also advisable to remove them, because later, when they heat up in the sun and stick to the frame, fused with it, this will be difficult to do. In the meantime, the tapes are very easy to remove.

Now the frame needs to be inserted into the window opening. To do this, you will need mounting wedges, which are placed in the corners (this is a mandatory requirement), as well as in other places where you deem it necessary.

Using a drill and a drill bit, special holes are made into which the fasteners are inserted. The first hole is drilled at a distance of 1.5 - 2 cm from the top edge. The bottom hole should be approximately the same distance from the bottom corner. The gap between two fasteners should not be more than 5-7 cm.
The anchor is hammered into the hole and then tightened. At the same time, you must tighten the anchor carefully, trying not to overtighten, otherwise the profile will bend, and this cannot be allowed. This operation - tightening the anchors - is continued as many times as necessary.

After this, ebb tides should be installed outside. Before installation, self-adhesive waterproofing should be applied to the part of the frame that is located outside. Grooves are made in the side openings (the edges of these ebbs will need to be inserted there later).

On that part of the opening where the ebb will rest on the wall, a special profile is installed, to which the ebb will then be attached. If the height difference is small, you don’t have to install the profile, but simply apply a layer of polyurethane foam. Then the ebb should be placed under the ledge of the frame and attached to it with self-tapping screws. Along the lower edge of the ebb, you also need to fill it with polyurethane foam.

Now let's take a closer look at the second method of installing plastic windows with your own hands - using plates.

This method is much simpler, although, as we have already said, it is less reliable. Installation using this method involves installing thick metal plates.

They should be installed at the same distance as the anchors in the first installation method - approximately 2 cm from the edge, and no more than 7 cm between those in the middle. The metal plates are simply screwed to the profile using self-tapping screws.

In all other respects, do-it-yourself installation of plastic windows is completely identical to the first installation method. In the same way, the window is leveled in three planes, after which all actions are identical. Simply, unlike the first method, they attach not the frame itself, but metal plates, and attach them to the so-called dowel-nails. The peculiarity of the fastening is that they first drill a hole, then bend the metal plate, insert a dowel into the hole, put the plate in place and tighten the dowel.

The main mistakes when installing plastic windows with your own hands

If you install plastic windows incorrectly, this can lead to the fact that the house will be cold; water will flow into the room through improperly installed ebbs. And the expensive structures themselves will quickly become unusable. And if professional installers sometimes make mistakes when installing PVC windows, then, of course, an amateur who installs plastic windows with his own hands is not immune from them.

Let's look at the 10 most common mistakes made when installing plastic windows.

The window size is incorrect

This is usually a consequence of incorrect, careless measurement of the window opening, and, accordingly, the manufacture of an unsuitable window structure. And in case the window is too large in size. And if the size is very small, it is simply impossible to install such structures.

Poor preparation of the window opening

If the surfaces are poorly cleaned, there is construction debris, dust, potholes left on them, or, on the contrary, parts of the wall protrude on the surface of the opening, the polyurethane foam will not fit as tightly and evenly as is necessary for high-quality installation of plastic windows with your own hands. In addition, this kind of pollution absorbs moisture very well, and it will soon end up inside your apartment.

Ignoring wall insulation

If a plastic window is installed without taking into account the thermal insulation of the wall, then cold air will penetrate into the apartment at the joints. Therefore, it is imperative to take into account the layers of walls when installing plastic windows. If the wall consists of one layer, the window should be placed exactly in the middle of the wall. If the wall is double-layered, the window should be installed at the very edge, as close to the insulation as possible. And if the wall is three-layer, then it is necessary to install a PVC window directly in the plane of the wall insulation, in order to avoid heat loss.

Incorrect distance between the window frame and the slope

If the window frame is located too close to the slope, the seal in this place will be of poor quality, and moisture will begin to appear and accumulate in these places. If, on the contrary, the frame is located too far from the slope, then there is a risk of deformation, since the load on the anchors or metal plates is too great.

Incorrect size of window sill

The window sill should be slightly narrower than the window frame itself. If it is a different size, or they decide not to install it at all, then water will penetrate under the window frame due to the lack of a normal seal in this place, and as a result, the wall will constantly be wet. Metal parts can simply corrode after a certain time.

Poor quality fastening of PVC window to the wall

If you skimp on dowels or anchors and there are too few of them to attach the window structure to the wall properly, over time the position of the window will change, the frame will become deformed, and it will be difficult for you to tear off and close the window.

Not enough polyurethane foam

Polyurethane foam is practically the only material for insulating a window structure and the wall itself to which it is attached. If there is not enough foam, the heat will escape. Therefore, the gap between the slope and the window frame must be filled properly, not sparing the mounting foam.

No insulation tape

If you decide not to use the insulating tape required by GOST on the inside and outside of the window structure, be prepared for the fact that the thermal insulation will gradually become worse and worse. Accordingly, the windows will deteriorate much faster than you would like.

Therefore, if you decide to install a plastic window with your own hands, try to go through all the necessary steps and perform all the necessary actions efficiently, carefully and slowly. Then your beautiful plastic windows, installed by yourself, will delight you and your household for many years.

To independently install a plastic window in your apartment or house, you do not need to have any special skills or special tools. Even a self-taught installer can insert it correctly into the opening and secure it with anchor bolts. It is enough to know how to handle a building level and a hammer drill. Only the installation must be carried out strictly according to the rules prescribed in GOSTs and instructions from manufacturers of PVC window products. Otherwise, this transparent structure will not last long.

Required tools and materials

Installation of a plastic window is carried out in five stages:

1. Removing the old window frame.
2. Preparing the opening.
3. Installation and level adjustment of a new frame with sashes.
4. Fixing the drainage system on the outside of the window.
5. Foaming the installation gaps and installing a window sill with slopes.

In addition to a hammer drill and a level, to install a window you will also need a hammer, a screwdriver, a water sprayer, a spatula, metal scissors and a pry bar. Consumable materials must be purchased in advance: polyurethane foam, silicone, anchor bolts or metal plates with self-tapping dowels and plastic construction wedges (or prepare small pieces of wood).

Required tools for installation

You will also need vapor-permeable self-adhesive and waterproofing tapes. Plus, the PVC window kit should include slopes, a stand profile, a window sill and a metal sill. If all this is available, then you can begin installation.

Dismantling an old PVC window and preparing the opening

To get rid of an old wooden or plastic window, you need to remove the sashes and make a cut on the side of its frame with a hacksaw. Then, using a pry bar, one of the resulting parts is pulled back and, by hand, pulled out of the wall together with fasteners. Afterwards, the procedure is repeated with all remaining fragments of the deleted window. Then the insulation is removed from the opening (if it is there) and everything that can fall off (for example, mortar).

Sectional design of plastic windows

As a result, only bare and even ends of the walls made of brick, concrete or wood should remain. If these surfaces have chips, cracks or potholes with a depth and size of more than 1 cm, then they must be repaired with concrete mortar. There is no need to do anything special to align it with the new plastic window; all the same, then the small cracks and recesses will be filled with polyurethane foam. However, it is not worth leaving deep noticeable defects without repair.

Possible errors with measurements

Before you continue to work and install a plastic window with your own hands, you need to remove dirt, dust and oil stains from the surfaces in the opening. If you have to install a window structure in winter, you also need to remove snow and frost, and then warm the ends of the wall with a hair dryer to remove moisture.

Window installation

Installation of PVC windows with fixation in the opening can be done in two ways:

1. Anchor bolts through the frame profile.
2. Plates secured to the side of the frame with self-tapping dowels.

The first option is more reliable. However, with this technology for installing plastic windows, the frame profile turns out to be drilled through. As a result, its thermal insulation efficiency decreases. If a window unit needs to be installed in a building erected in a region with a cold climate, then it would be best to abandon this method.

The second option for fastening plastic windows is considered less reliable and is not recommended in the presence of strong wind loads. But in winter, the heat will definitely not escape from the house through the holes in the profile into the street.

Installation of windows with different slope options

Holes for fastening PVC windows are drilled in the wall with a distance of 15–25 cm from the corners of the opening. Plus one or two more holes on the sides, bottom and top are made in the middle with a step of no more than 70 cm between them.

The new window is directly positioned in the opening using the stand profile and adjusting wedges. Plus, you will need to glue a vapor-permeable gasket (PSUL) around the outer side of the frame in advance. And you should not tighten the bolts or screws all the way immediately after leveling the structure in the opening using a level. First, you also need to secure the ebb and flow to drain rainwater and waterproofing.

How to position the window frame correctly

Drainage

The next step in installing a plastic window with your own hands is to attach the drainage system. It must be installed in any situation. Without this external element of the window unit, all the rain water will fall onto the foam and under the frame. The inevitable result will be the destruction of the installation seam and the formation of gaps between the profile and the wall.
The ebb is fastened with self-tapping screws not to the window itself, but to the stand profile under the frame. In this case, the waterproofing tape is first laid. And then a drainage system is placed on top of it and fixed in place. Then foam is sprayed under this metal strip.

How to position the drain correctly

By the way, if you don’t yet have electricity in your country house, we recommend reading the article about gas generators for your home, as well as the benefits of a gasoline generator for a private home.

Assembling a plastic window

Before installing a plastic window into an opening, all opening sashes must be removed from it so that they do not interfere with the installation work. Plus, the double-glazed window from the blind part of the structure is also removed. To do this, you need to pry up the plastic beads with a spatula and knock them out of the groove.

Reinstallation of sashes and double-glazed windows in plastic windows is carried out before foaming the gaps around the frame. If they are not put back in place, then the foam cannot be blown out. After spraying, polyurethane foam expands 1.5–2 times. Moreover, this happens with the creation of quite strong pressure on the frame profile. It can easily be bent so that later it is simply impossible to insert the sashes back.

Window sill installation

Installing a window sill on a window largely follows the same technology as installing a drainage system. Only instead of a waterproofing tape, a vapor barrier is used indoors. If the waterproofing on the outside prevents moisture from entering the assembly seam, then the vapor barrier on the inside is designed to evaporate it into the house.

Installation of windows with and without waterproofing

The foam in the gap should not get wet or freeze; this will instantly destroy it. The window sill is laid on wooden guide supports located perpendicular to the window and along its entire length in steps of 30–40 cm. In this case, an inward slope of 2–3 degrees must be maintained. This is necessary so that the resulting condensate drains from the window sill and does not stagnate in the corners.

After alignment and alignment of the window sill, it is inserted with pressure under the lower edge of the frame. Then the gap is foamed from below and a weight is placed on top of the plastic plate. Once the foam has hardened, it is securely fixed in place.

To prevent the installation of plastic windows with your own hands from ending in alterations, you should:

• make the PVC window sill a couple of centimeters shorter in length than the window opening (a centimeter of free space on each side should remain to compensate for the thermal expansion of the plastic);
• squeeze the foam out of the container evenly and without excess, otherwise when it expands it will deform the frame profile, as well as the slope and window sill plates;
• The final tightening of the bolts (self-tapping screws) should be carried out immediately before re-installing the sashes into plastic windows and foaming the installation seam;
• Before foaming, wet the surfaces of the opening and frame with a splash of water so that the foam sticks to them more firmly.

Where to use insulating materials when installing windows

Conclusion

Installation of PVC windows can be done independently. The main thing is not to overdo it with foam; if there is too much, it easily squeezes out the plastic. Compared to other construction work around the house, installing a roof or caisson for a well is much more difficult. With window structures everything is much simpler.

Self-installation of a plastic window - detailed instructions

Until recently, exclusively wooden window frames were used in the glazing of residential buildings and industrial buildings. Today, many consider them relics of the past and are in a hurry to replace them with modern metal-plastic structures. Indeed, in addition to high performance characteristics, they are much cheaper than wooden frames. To install plastic windows with your own hands, you don’t need to have superpowers. Almost any person who can hold a tool in their hands can cope with such a task.

However, do not forget that each job requires certain skills and craftsmanship. Lack of experience in installing windows can lead to a number of troubles. These are systematic breakdowns, loose fit and high throughput of street air into the apartment.

To avoid the above points, in this article we will provide step-by-step instructions that will help you install your windows correctly and efficiently. If you still decide to trust professionals, know that some of them are not really professionals, and for a number of reasons they openly neglect certain stages of proper installation (some save time, others save money). Having an idea of ​​the work being carried out, you can easily exercise independent control over the entire process. And subsequently you will enjoy the high-quality operation of your windows, which will bring joy to all family members.

The main stages of installing new windows:

• taking measurements;
• dismantling old windows;
• preparing openings;
• installation of a metal-plastic structure.

Not everyone knows that the manufacturer gives absolutely no guarantee for their services if they install windows on their own. Therefore, if various troubles arise during the installation process, you should not hope for a return or replacement. All metal-plastic structures are manufactured strictly according to pre-agreed dimensions. If you make a mistake, the window may not fit in the opening or may end up being much smaller. And it will only be your fault. The company's employees are solely responsible for the implementation of each stage of product installation.

Also, any inaccuracy made when installing a metal-plastic window will deprive you and your loved ones of all the advantages of a modern design and the expected level of comfort.

Window measurements

When taking the necessary measurements, you need to pay attention to the fact that window openings exist with and without a quarter. Accordingly, their formulas for calculating sizes are different.

For the first case, we must measure the width of the opening between the existing quarters, this is done at the narrowest point. And then add 3-4 cm to the resulting figures - this will be the width of our plastic frame. In addition, it is important to check: the largest distance between the vertical quarters should not exceed the design width of the block.

The height is determined by measuring between the top quarter and bottom surface of the window opening.

If the window opening is without a quarter, the required values ​​can be obtained by subtracting 5 cm from the vertical dimension (to place a window sill) and 3 cm from the horizontal dimension.

When determining the size of the window sill and ebb, it is worth considering the following details:

1. Often the size of a window sill is chosen based on its functionality. It should cover the heating radiators and house flowers should be placed on it;
2. The length of the window sill is taken to be 8-10 cm longer than the window opening, its edges should be recessed into the cavity of the slope by approximately 4-5 cm;
3. The dimensions of the ebb are calculated taking into account the planned insulation. It is recommended to leave it protruding 5-10 cm from the wall.

Features of measuring balcony windows

When calculating the width of balcony windows, the length of the parapet is taken as a basis; the entire structure will rest on it. Also, on both sides it is necessary to subtract 6-7 cm, which will be needed for installing the corner profile; it is used to connect the window blocks of the front and side parts. The distance from the roof to the railing, with the exception of the difference of 2.5-3 cm, which is important to set aside for gaps for fastening, will be the height.

Regarding the side balcony frames, their dimensions are determined in the same way. The only thing is that you need to subtract 6-7 cm from the width to install the corner profile, as well as 2.5-3 cm for the gap from the wall to the window.

Features of window measurements in private houses and old buildings

When taking measurements of windows in private houses and old buildings, it is recommended to first knock off part of the slopes on both sides (in the measurement areas). This is done in order to see what the space occupied by the window opening is like. It often happens that there are dilapidated cement mortar and various insulation materials that can crumble during the process of dismantling the existing window. The positive point here is that the new plastic structure can be slightly enlarged by expanding the cleaned window opening.

Ordering a metal-plastic window

Before contacting a company with an order, you should think about what type of double-glazed window is right for you. It can be one-, two- or three-chamber. As for fittings and fasteners, you can also choose them yourself.

The manufacturer's consultants will help you understand the technical characteristics of plastic windows that will be preferable for your home at the time of ordering.

Some important points during installation

When installing windows yourself, you should pay attention to the following:

• the metal-plastic structure must be well secured;
• The mounting foam used to fix the windows must be plastered on both sides (this will prevent it from sagging and deforming the frame in the future);
• It is very important to align the structure vertically and horizontally using a level (this will help avoid warping).

How to install metal-plastic windows with your own hands

Before starting installation, prepare everything you need for work:

1. Window frame with fasteners;
2. Building level;
3. Polyurethane foam;
4. Mount;
5. Bulgarian;
6. Windowsill.

The process of preparing a window block

Window preparation is an important stage of installation work that you carry out yourself. If necessary, the double-glazed windows and hinged sashes themselves are dismantled from the window structure. To release the double-glazed window, a chisel is used; very carefully, you need to use it to pick out the glazing bead (fastening) and after a light blow on the tool it will come out of the grooves. Then the vertical fasteners are removed, top and bottom. The released glazing beads will need to be marked; sometimes their sizes can differ significantly, which will lead to the formation of gaps of several millimeters. The glass unit will come out of the grooves on its own if you tilt the frame a little. Gently lean it against the wall, creating a slight angle.

Decorative plugs must also be removed from the swing doors, then unscrew the clamping bolts. If there is a transom opening system, release the top of the sash by turning the handle to the center and remove the hook from below.

Ultimately, you should end up with a free frame, on which there are only lintels separating and reinforcing the sashes. On the inner surface of the plastic frame, holes are cut along the contour for mounting anchors. The minimum number of such holes should be three for the sides, two for the lower and upper ends. For drilling, use metal drills, because the window is made of metal and plastic, and inside it has a metal inclusion for strength characteristics.

To fix the frame, it is preferable to take anchors with a diameter of 0.8-1 cm and metal drills of the same size.

Comfort and coziness for you and your loved ones with new windows installed by yourself!

How to install a plastic window with your own hands?

Buying and installing new windows is not a cheap pleasure, and a significant portion of the costs comes from installation fees. You can reduce costs by doing this part of the work yourself. We will tell you how to install a plastic window yourself, providing step-by-step instructions with photos.

Measurements required for the manufacture of a plastic window

The ease with which you will succeed or fail will subsequently depend on how correctly you take the measurements. After all, having made a larger window block, you will be forced to increase the opening, and if you make a smaller mistake with the dimensions, you will be forced to increase it.

It is necessary to determine the dimensions of the future frame based on the type of windows, which are:

• with a quarter, i.e. with a half-brick protrusion, which is located outside the opening and against which the window frame rests. Such windows are present in almost all typical buildings;

• ordinary, i.e. without protrusions. This design is used in buildings constructed according to individual projects.

Measurements of a regular window

Using a tape measure, measure the length and width of the window opening, add 5 cm to these indicators (per polyurethane foam) and write down the data obtained. In addition to the dimensions of the window frame, you need to measure the depth of the slopes, as well as the depth and length of the window sill. The last parameter is calculated based on the distance between the boundaries of the vertical slopes, to which 8-10 cm are added.

Quarter window measurements

In this case, you will have to measure the distances between the horizontal and vertical edges of the protrusion and add 5 cm per polyurethane foam to the resulting figures.

The video will tell you more about the nuances of measurements:

When ordering a metal-plastic window, do not forget to discuss with the manufacturer the number of double-glazed windows and the profile size, as well as the list and quantity of fittings and fasteners. If the climate of your area is not severe, and the windows do not face the roadway, feel free to order two double-glazed windows and a profile 6 cm wide. The lower the temperature outside the window and the more noise on the street, the greater the number of double-glazed windows and the size of the profile.

The procedure for dismantling the old frame

To install a plastic window yourself, you need to get rid of its wooden predecessor. Dismantling should be done carefully so as not to dismantle half of the wall, which will then have to be restored, wasting time, money and effort. At the same time, remember about safety precautions, because working with glass is very dangerous, and the slightest mistake can land you in a hospital bed.

First, remove the opening parts of the windows from their hinges. Remove the glass by first removing the glazing beads. Using a grinder or hacksaw, make cuts in the frame and other parts of the window unit.

Using a pry bar, remove the elements of the old structure from the opening, which is then thoroughly cleaned of construction debris and dust.

Now it's time to find out how to install a plastic window yourself.

Installing a plastic window with your own hands: instructions

To install a plastic window yourself, prepare the tools and materials you will need during installation:

• self-tapping screws (4x35 mm, 4x25 mm);

• screws (5x60 mm, 3.8x25 mm, 3.9x25 mm);

• anchor plates;

• polyurethane foam;

• waterproofing and vapor barrier tapes;

• mounting wedges;

• low tides;

• windowsill;

• plumb line;

• level;

• PSUL;

• perforator;

• screwdriver;

• screwdrivers;

• a hacksaw with a fine tooth for cutting the window sill;

• tin snips to trim the flashing.

Before installation, remove the sashes from the window block.

Install the mounting plates. The procedure is as follows: place the plate along the end of the window block, then turn it with the other end towards the room, fix it with a self-tapping screw (4x35 mm).

Please note: the distance between the plates should not exceed 600 mm.

Before you begin installing the structure in the opening, you need to apply marks for fasteners and PSUL. Align the position of the structure in the opening (this is why a plumb line and level are needed), taking into account the following: the maximum deviation from the horizontal or vertical should not be within 1.5 mm per 1 m of the structure, but not exceed 3 mm over the entire length or width of the product. Secure the frame using mounting wedges.

Bend the plates and mark with a pencil the places on the slope where they will be attached.

If your window is a quarter window, then mark the outline of the adjacent opening on the outside of the frame.

Remove the frame and drill holes in the places you marked, where the anchor wedges will then be inserted.

Drive dowels into the resulting holes.

Use a brush and vacuum cleaner to get rid of dust. Apply sealing tape to the frame. In the case when you are dealing with a quarter window, the tape is glued to the outer part of the frame at a distance of 3-5 mm from the previously outlined opening contour.

In windows without a quarter, the outer seam is insulated using special moisture-proofing sealants after the structure has been installed.

Secure the window block in the opening using mounting wedges and remembering to check the correct position.

Fix one top side plate at a time and measure the diagonals of the window block. Their difference should be within the following limits:

Screw on the remaining plates and remove the wedges, leaving only the bottom and diagonal ones, then proceed to foaming.

Trim off the excess foam and stick a vapor barrier tape on the side of the room, overlapping the wall by 10-20 mm.

Attach waterproofing tape to the outside.

Set the tide. Insert it into the groove and screw it using self-tapping screws (4x25 mm).

Hang the shutters and then install the window sill. Adjust the handles if necessary.

You see, install a plastic window yourself not that difficult. The main thing is to have the desire and follow our advice.

Greetings, my hands!

How to install plastic windows yourself- we will try to get an answer to this question in this article.

With the onset of spring, many of us have itchy hands, sweaty feet and a suspicious itch in one place! No, this does not mean that hands are starting to sprout from this place, although it may well be - most likely this is an aggravation of the spring hands-on. So it’s time to break, destroy, repair, build, and of course, get hands-on!

Not long ago I decided to do a budget renovation in my daughter’s room. And since the room is “dead,” I decided to make an opening in the wall and install a plastic window in it. Why metal-plastic? Yes, because thanks to such properties as: heat protection, tightness, easy installation - metal-plastic windows have firmly entered our everyday life. The slogan is: set it and forget it! I won’t argue that good old carpentry is much more environmentally friendly - it really is, but that’s not what we’re talking about today!

My handymen, I must warn you that self-installation has one negative nuance - this is that the warranty of the company where you order the product is lost. My advice to you is that you shouldn’t be afraid of this, since you can fix the window yourself.

Companies selling plastic windows provide installation services and often keep silent about the fact that you can refuse to install them. To correctly measure and install a PVC window, you don’t have to be a professional. This work, although painstaking, is not too complicated; special knowledge is not needed here. It is advisable to know how to handle a hammer drill and have straight hands. And in addition to invaluable experience, you will also save a lot of money!

Tool

Necessary tools and materials for work:

1. Screwdriver
2. Mount
3. Building level
4. Hammer
5. Hammer
6. Dowels
7. Anchor plates

If all of the above is available, then you can proceed :)

Removing an old window or preparing an opening

As I already said, usually in apartments and houses plastic windows are installed instead of old wooden ones. Removing a wooden window is relatively easy. First you need to remove the sashes with glass. To do this, they need to be lifted and removed from their hinges. It is often impossible to lift the frame by hand, so it is better to use a pry bar here, unless of course you are Arnie Schwarzinger!

A window without sashes looks like a wooden frame with a vertical crossbar in the middle. This crossbar should be sawed in half to make removing the frame easier.

Before removing the frame, you need to remove the window sill. In multi-storey buildings, old window sills are usually reinforced concrete. They are not easy to take out. Here you need a sledgehammer, with which you need to break the window sill from the bottom up, and then pull it towards you. If it doesn’t help, then drill a small hole and lay in dynamite. We light the wick, wait for the old window sill to disappear. Guys, if anything, then I was joking :), otherwise you never know?!

When dismantling a window unit, you must first loosen and break out the sawn vertical crossbar. After this, the window frame is removed in parts, starting from the top. When dismantling is completed, you need to clear the window opening of construction debris and insulation. It is also advisable to remove small debris and dust using a brush around the perimeter of the entire window opening.

This is about removing an old window, but I had to make the window opening from scratch. To do this, in the wall into which daylight would soon spill, I had to mark out the future dimensions of the window. Usually they take measurements first, but for me it’s the other way around - I adjust the opening to fit the future window :)

Using a hammer drill, I hollow out the opening (sorry about the quality)

Then I reinforced the window opening with metal lintels

I plastered all the irregularities and the opening is ready!

Preparing a plastic window for installation

So, here, in fact, is the hero of the occasion.

A window from some Turkish company, purchased in Leroy for 4,500 rubles. Dimensions - 1200 mm by 800 mm.

To facilitate installation, it is necessary to remove the glass unit from the window. Usually, when purchasing new windows, the manufacturer deliberately does not hammer the glazing beads in too tightly so that they can be easily removed, but if you do not see any cracks, then a spatula is in your hands. Be careful not to leave any chips or dents on the window itself. By lightly tapping the glazing beads should come out freely.

Due to the fact that I have a window with only one sash, I decided not to remove the double-glazed window, but simply remove the window sash from the hinge. To do this, I carefully knocked out the rod in the top hinge and simply removed the sash from the bottom hinge.

Friends, if your window is not very large, then it is better to insert it using anchor plates, so as not to once again violate the integrity of the factory assembly.

Do-it-yourself installation of plastic windows

There are two ways to install metal-plastic windows.

Most often, plastic windows are installed on canopies. The second method, called anchor installation, involves removing the double-glazed windows from the window block, and then drilling the plastic block from the inside and securing it to the window opening using anchors. Awnings are much easier to install; in this case, there is no need to disassemble the window.

So, let's look at both methods in more detail.

• Installation of windows on anchor plates

So, this is perhaps the most popular installation option.

The canopy is a bar with a locking mechanism and holes. Awnings are mounted directly on the window every 50 cm and with a distance of 20 cm from the edges. They are also called anchor plates.

We place the window in the opening, having previously placed wooden blocks under it, the width of which should be slightly larger than the width of the future metal-plastic window sill. Naturally, we don’t forget about the level.

We wedge the window with wooden “bogs”, and if there are plastic ones, then it’s generally good.

Mark the drilling points for the canopies with a pencil or marker. Then remove the frame and drill holes.

We put the frame back and attach the fasteners.

As you can see, in the absence of anchor plates, I attached ordinary construction hangers. Many will criticize me, but I want to make a reservation right away - I am not a supporter of anchor plates at all, since all sorts of wind loads and the like occur. Therefore, for the correct installation of a plastic window in a brick house, I subsequently reinforced the window with anchors.

We fasten the hangers by pre-drilling holes - a hammer drill will help you.

We foam the window, after wetting the walls for better adhesion of the foam and the wall.

After complete drying, cut off excess foam.

• Installation of windows on anchors

This method is considered more primitive than installation on awnings, since there is a high risk of damage to the window.

Friends, if you have large windows, then only anchor installation is suitable for you, as it is the most reliable and durable.

So, let's look at all the installation steps step by step:

• First, you need to remove the double-glazed windows from the window.

• We install the window in the opening, having previously placed bars or special plastic “bobs” under it.
• We set the window level - first horizontal, then vertical. This is the most important step in the installation - treat it with the utmost care.
• After this, we preliminary mark the future holes for the anchors and use a metal drill to make holes.
• Insert anchors and secure the window
• After the window is placed on the anchors, it is necessary to assemble the window in the reverse order. First we insert double-glazed windows, then we insert glazing beads - first horizontal, then vertical. In order for them to fit tightly into the grooves, we tap them with a rubber hammer.

After the window is assembled, it must be foamed. All further operations on cutting foam and installing window sills are absolutely no different from installing metal-plastic windows on canopies.

A newly installed window should not be used for about a day to prevent distortions.

How to install a plastic window with your own hands - video

That's all guys - I hope I was able to give you an answer to the question - how to properly install plastic windows in a house. All that remains is to install the window sill and mount the ebb.

When purchasing a window, we plan that it will be able to serve well for many decades. However, this is only possible if the window is installed correctly. Almost all specialists have their own methods and secrets, but there are also special fixed standards - GOST and SNiP. It is the installation of PVC windows in accordance with GOST that can give the highest quality results.

Regulations

Installation of PVC windows in accordance with GOST will guarantee its long and trouble-free service. Today, all types of work related to this area are regulated by four main standards:

• GOST 30674-99. It contains general information on the issue and basic requirements for windows. There is practically no mention of the installation process itself in this GOST.
• GOST R52749-2007. This standard focuses on the process of installing windows using vapor-permeable, self-expanding sealing tape.
• GOST 30971-2012. This document contains the most detailed information on the issue. It also contains exact requirements for window sizes, device parameters and joint filling materials, methods of fastening structures and similar information. It also describes the requirements for regulatory documentation, some warranty obligations of the work contractor and general requirements for the performance of work. This standard was introduced at the beginning of 2014 and replaced the outdated GOST 30971-2002 for window installation.
• SNiP 02/23/2003. The standard sets the parameters for thermal protection of premises. Suffice it to mention that it requires the installation of a 3-chamber double-glazed window for most climatic zones of Russia and a 5-chamber double-glazed window for Siberia.

The standards take into account the climate zone in which the plastic window will be installed

All of the above regulatory documents are valid, but not mandatory. The only exception was various requirements related to safety in one way or another.. Compliance with GOSTs only helps to achieve the highest quality window installation.

Preparing for installation

The installation of plastic windows according to GOST is not much different in general terms from the usual installation of a PVC window. The main differences lie in the nuances and compliance with a number of requirements. The technology for installing plastic windows is as follows:

Measurements

Before starting work, a number of measurements should be taken. The dimensions of the window are set as follows: the width of the window is the width of the window opening, from which the double width of the installation gap (which will be on both sides) is subtracted, the height is the same. According to GOST, the minimum width of such a gap is 2 cm, and in calculations the figure most often used is 2.5-3 cm.

When installing a quarter window, measurements are taken from the outside

If we are talking about installing a window in an opening with an external quarter, then all measurements should be made from the outside. The width will be the distance between the quarters, increased by the size of the frame plant per quarter, which ranges from 2.5 to 4 cm. The height is determined in the same way.

Preparatory work

After the windows have been manufactured and delivered to the customer, work should not begin immediately. It is recommended to first prepare the room: clear the space near the window for convenient work, remove unnecessary things and furniture, cover the walls and remaining objects with film or thick fabric. The doors are removed from the frame, and the cavity of the stand profile is filled with heat-insulating foam. It is recommended to do the latter one day before installation.

Particular attention should be paid to the opening itself - it must be cleaned of dirt and dust in advance. If there are noticeable irregularities, they are leveled with putty.

Fastening

GOST stipulates two main types of window fastening. The first is done in the mounting plane - self-tapping screws are attached directly through the frame. This option is used most often, but requires that the door leaves and double-glazed windows be removed from the frame in advance. The advantage of this method is the ease of installation in the opening.

Most often, self-tapping screws are used for fastening

The second option is based on the use of reinforcement mounted in the frame during production. The entire structure can be mounted. It should be noted that its weight will be quite large, so the process will require certain efforts and skills.

Installation work

Installation of plastic windows according to GOST provides for one important point: the frame is not installed on a bare brick or similar base. Instead, small wooden blocks impregnated with solutions are placed. They will help in aligning the window.

After this, either a separate frame or the entire structure is placed on them, which depends on the preferred type of fastening. For greater stability and reliability, the supports are left as part of the structure, and wedges are knocked out between the window and the wall on top for fixation. After this, the frame is attached from the sides in the same way. By controlling the process with a level, the frame is leveled, and adjustments are made by adding substrates.

The frame can be fastened, according to GOST, through pre-drilled fasteners. You should start from the bottom, gradually moving higher. To top it off, the structure is additionally checked for horizontalness and all screws and anchors are tightened.

Drain installation and window assembly

Most often, a special groove is provided on the outside of the window into which the drainage system is mounted. GOST states that during installation it must be foamed. If you need to create a more durable structure, the drainage system is additionally secured with screws.

The drainage system is mounted in a special groove on the outside

Upon completion, another control check of the entire structure is required: for strength, verticality and horizontality. After this, all that remains is to assemble the window. The assembly process takes place in the reverse order of disassembly: during the process, stops, handles and other accessories are returned to their places.

Filling gaps

GOSTs pay special attention to filling gaps. This procedure is almost always performed using polyurethane foam-based polyurethane foam. This material has been tested over years of work, but still has a number of disadvantages. First of all, its resistance to environmental influences and ultraviolet radiation leaves much to be desired. That is why GOST standards require maximum insulation of all seams on all sides - this will avoid destruction of the insulation, which can result in loss of tightness, fogging of windows and the penetration of cold from the street into the house.

The insulation procedure is as follows: waterproofing tape for PVC windows is glued from the inside around the entire perimeter. The tape must also have vapor-tight properties. A strip of foil is glued at the bottom, which will subsequently appear under the window sill board. They pass along the outside in a similar way. Adhesive strip PSUL (moisture-resistant and vapor-tight). This membrane film can allow steam to pass out.

Installation of windows in accordance with GOST requires mandatory waterproofing of gaps

Both mentioned materials are characterized not only by the fact that they are not difficult to find on the construction market. They also differ in accessibility, that is, the final price of the work will not increase that much, but the quality will increase significantly. In addition, the structure mounted in this way will last several years longer.

To fill the gap when installing PVC windows according to GOST, the strips are slightly bent and the surface is wetted from the inside. Apply the composition using a pistol. Foam is used as a filler, intended for use all year round. According to GOST, ordinary foam can also be used, but only at temperatures up to 30 degrees below zero. Considering the conditions in most regions, such seam insulation in Russia turns out to be of little use.

Window sill installation

At the last stage of the work, the window sill is installed. This process is considered quite simple - you just need to adjust the size and, if necessary, trim the finished window sill so that it fits perfectly under the frame. According to GOST 30971, it is allowed for the window sill to extend onto the walls at a distance of 5 to 10 cm. Pegs are used to create a level, after which the cavity under the board is sealed with polyurethane foam or mortar. Experts recommend making a slope of 1-2 degrees towards the room during installation.

When installing a window sill, it is necessary to adjust it to the correct size

To decorate the window sill, plastic panels are used, which are attached to the initial profile using a clip. The casing, which wraps around the corner, is secured with self-tapping screws and covered with decorative film on top. All that remains is to put on the end caps and seal the seams with sealant.

Many construction companies interpret GOST and SNiP standards as they wish and can simply ignore them, and there is no need to say again what the consequences of incorrect installation are. There are two ways out: either carefully monitor the installation process and immediately notice violations, or install windows according to GOST on your own.
