How to insulate plastic windows for the winter. Replacing the assembly seam, installing insulated slopes and window sills How to insulate plastic windows in an apartment

A seemingly perfect solution like plastic windows has a number of potential problems.

The room may not be warm enough and sometimes there are even drafts. When the window opening starts to blow, and the common cold becomes a constant companion, it’s time to address this issue. It is worth approaching this problem thoroughly, having previously purchased the necessary building material so that the insulation process does not smoothly turn into protracted unfinished construction or, even worse, into protracted treatment.

What materials and tools are needed for emergency elimination of drafts and subsequent high-quality insulation.

Polyurethane foam.
Silicone sealant.
Adjustment key for fittings.

Reasons for poor window insulation

On at this stage the cause of the draft should be determined.

The fittings are not working properly.
The sealing rubber bands of the sash and frame have dried out or do not press tightly.
The beads do not hold the glass tightly and do not press it.
It blows from under external ebbs, window sills or internal slopes.
The window opening was not well foamed and thermally insulated during installation.

Adjusting fittings

First, we determine the density of the window sash. This is done using a regular notebook sheet. We clamp the sheet with the window sash and close it tightly with the handle. Now we are trying to pull it out, if the sheet does not come out, or it comes out hard, in this case there is no need to worry, the sash has an excellent rebate. If the sheet comes out easily when the sash is closed, then we proceed to eliminate it. We open the sash and on the locks located on the sash fittings, use the adjusting key to set the winter position, turning it 90 degrees. This will ensure a tight seal. And again we return to our sheet.

Replacing rubber seals

If the sheet comes out easily again, then it’s all about the sealing rubber of the sash and frame. Over time they dried out and lost their elasticity. Replacement required. We cut out a small piece from the sash, also from the frame (they are different in volume), and go to the nearest retail chain of furniture fittings supermarkets, to the market, or contact installers. You need to measure how many meters of both seals you need.

Loose fit of glazing beads

Finding and replacing glazing beads is a rather tedious task; it is better to turn to specialists. Well, if you want, eliminate the draft, without replacing and on our own, then carefully remove the glazing beads from the landing grooves. This must be done using a special spatula, with short and sharp blows, at an angle of 45 degrees along the body of the bead. Be sure to hold the glass: with your hand, with your head, and ask your neighbor so that the glass does not fall out of the sash when removing the glazing beads. We load a bottle of sealant into a piston gun and fill the space between the glass and the sash, along the perimeter of the sash (frame, if the window is blind, without a sash). Using a rubber hammer, hammer the glazing beads into the grooves of the sash. You need to start with short beads and from the corner of the sash. Now there will never be any blowing in this place, even if the glass is not pressed tightly.

Blows from the street side from under the tides, cornice

In case of poor-quality installation of external flashings and cornice, unfilled cavities remain between them and the wall opening, in which correct installation, there must be heat-insulating material. It provides good thermal and noise insulation of the house. To eliminate this problem, you need to open the sash and carefully examine the places where the metal ebbs and cornices adhere to the wall.

If you find gaps, cracks, voids, you need to fill them polyurethane foam. To do this, we definitely need insurance. And by leaning half a length out of the window, you can easily reach places that are not filled with thermal insulation.

If your windows are not standard (stained glass, balconies, loggias), do not take risks! Contact the specialists.

Excess dried foam can be cut off after a few hours. When it is not possible to turn to specialists due to the banal lack of extra money, and at the same time there is no desire to be exposed to drafts, we abandon this idea until better times and carry out insulation from the inside.

Insulating the window opening under the window sill

If you find that the space between the cornice and the wall opening is not filled with foam, but with outside there is no way to fill it. Then we do it from the inside. Under the window sill there should be a distance to the opening of about 2 centimeters, filled with heat-insulating material. Using a screwdriver, knife or stiff wire, remove the foam to gain access to the unfilled voids under the street cornice. It is not necessary to select all the foam; you need to select enough to stick the nozzle of the gun through to evenly fill the voids under the eaves. We load the cornice so that the foam does not lift it.

We insure the cargo against accidental loss (there may be people below!)

We seal the joint between the window sill and the frame with silicone sealant from the inside and outside, and remove the excess with a wet rag.

Thermal insulation of a window opening

One of the reasons for drafts is insufficiently filled voids between the window (wall) opening and the window frame. Therefore, we look through it for the presence of insulation and check for the absence of drafts. You can check it using the flame of a lighter (candle), or with the palm of your hand.

To be completely sure, in the absence of a draft, you can ask someone to open and close the door to the room. While you smoothly carry the open flame of a lighter (palm) along the window opening. Air draft will definitely make itself felt if there are gaps in the opening.

After eliminating drafts, energy-saving film is used for more effective insulation and heat retention. The film is self-adhesive and to install it you need to remove the glass from the window. Remove dust and dirt, moisten the glass surface with soapy water. Apply the film, spreading it evenly. Use a rubber spatula to squeeze out the remaining solution. Use a utility knife to trim off excess film along the edges of the glass. Carefully insert into the frame (sash), hammer in the glazing beads with a rubber hammer.

With these practical tips, you can easily insulate your windows.

With the advent of metal-plastic windows, there is a tendency for their widespread implementation. In many matters, they are indeed more practical than wooden ones. Many users cite their tightness and lack of need to care for them, like wooden ones. But after a certain period of time they need maintenance, so it is important to know how to insulate plastic windows. The article will discuss the reasons for the need for such maintenance, as well as ways to identify problem areas.

Causes of problems

Consumers who choose plastic windows are mistakenly confident that they will be able to remain airtight throughout their entire service life. At first, such windows really reduce heat loss and coolant bills. Much depends not only on the quality of plastic windows, but also on the method of their installation. If the latter was done in violation of basic rules, then you may not see the difference with old wooden windows. In addition to errors that were made during installation, the following factors can worsen the situation:

wear of insulation;
detachment of linings from the glass unit;
changing the window geometry;
wear of shut-off valves;
wear of the PVC base;
improper installation of window sills;
violation of slope finishing technology.

Insulation in most cases is presented rubber gaskets, which dry out and become unusable due to constant changes in temperature and humidity. The consequence of this is drafts and loss of tightness. Problem areas are also the places where the glass unit is pressed against the window frame. If the slats begin to lag behind, this will lead to condensation and the appearance of ice on the window. In production, the angles of the window frame and sashes are made ideal, but their geometry can be disrupted by physical influence. For example, the shrinkage of a building can change the angle, causing a sash to leak or a gap to appear near the wall.

Metal fittings, which are used in plastic windows to secure the sashes, fail over time. In this case, the window cannot be pressed with the proper force, which is why problems arise. Each material has its own service life, this also applies to PVC profile. It may also be the reason that the window has lost its seal. It can leak from under the windowsill. If during installation the window sill was replaced with a plastic one, then errors may have been made during installation, which left a gap through which cold air enters. Slopes require compliance with finishing technology so that they can fulfill their tasks. If they are not sealed enough, then problems are bound to arise.

Resolving issues related to the repair or maintenance of plastic windows can be entrusted to a company that specializes in this. Usually in the arsenal of craftsmen there are components that often fail and require replacement. The work will be completed quickly, but it is worth considering that you will have to pay for such a procedure certain part budget. Therefore, it is easier to insulate plastic windows yourself.

Identifying causes

Before you begin to eliminate the problem that has arisen in plastic windows, you need to accurately determine its location. To do this, you need to carefully inspect the window frame for any defects. If you couldn’t identify them visually, then you can do this:

tactile;
using a lighter;
a sheet of paper.

If you wet your hand in warm water and bring it to the window, then you can immediately feel the place where the draft breaks through the gap. Sometimes this is not enough, then you can resort to using a lighter or match. It is enough to light a flame and hold it near the problem area of the plastic window; if there really is a defect, then the flame will deviate to one side, everything will depend on the direction of the air flow. To identify loss of tightness due to insulation, a sheet of paper is used. You need to open the window, place a sheet of paper and close the window. If the sheet is easily pulled out, then we can safely talk about a leaky seal.

When to carry out work

It is not always convenient to maintain and insulate plastic windows in winter. That's why best time there will be a spring-autumn period. This is explained by the appropriate air temperature, which makes it possible to freely open and close windows without fear of catching a cold or increasing the consumption of gas or other media for heating. Insulation of plastic windows may require the use of building mixtures. Most of them are used only at above-zero temperatures, which is also the key to proper drying. Excessive humidity, which may be present in late autumn and winter, is also an obstacle to normal work. At optimal temperature It is easy to carry out not only internal but also external work.

External window insulation

Proper insulation of plastic windows involves external and internal work. The first include:

finishing of external slopes;
insulation of ebb tides.

Each type of work requires its own approach, so it is important to consider them separately.

External slopes

Most often, during the installation of windows, the external slopes are not finished, so they are the first point that should be taken care of when insulating a plastic window. Without this event, you can do whatever you want from within, but it will not have any effect. Insulating plastic windows on the street side makes it possible to move the dew point. This way, moisture condensation will not occur on the inside of the glass. This often leads to the appearance of mold, which not only spoils the appearance, but is also harmful to health. Another factor that requires finishing of slopes is polyurethane foam. If it is not protected from ultraviolet radiation and precipitation, it will begin to crumble, which will only intensify drafts.

To carry out the work you will need insulation, glue and tools. It is best to use extruded polystyrene foam as insulation for slopes. It has minimal thermal conductivity and is easy to install. This insulation also perfectly resists moisture and is not susceptible to rotting. To secure it to the wall you will need dowels in the shape of umbrellas, as well as special glue.

Pay attention! If you want to use stone wool to insulate a slope, you need to take care of its high-quality waterproofing. If this is not done, then it will pick up moisture and lose its insulating properties, which will not solve the problem.

The first step is to clean it well window slopes from garbage. If there are sagging marks left on them from the old plaster, then they should also be knocked off with a hammer or a hammer drill with a chisel. If there are cracks or other damage, they must be repaired using tile adhesive or a similar solution. After this, the surface is covered with a deeply penetrating acrylic primer. If the first layer is absorbed too quickly, then you can apply another one and wait until it dries completely. Using a construction knife, the insulation is cut to the required size. An adhesive base is applied to it and it is placed in place. At the same time, it should fit tightly to the window frame.

Using a hammer drill, several holes are drilled in the insulation and the wall. A small amount of foam is blown into them and plastic umbrellas are clogged, which will additionally press the insulation to the wall surface. All remaining gaps that may exist between the insulation and the plastic window are sealed with glue. The insulation is covered with a small layer of glue. After this, a reinforcing mesh is mounted on it, which increases the strength of the slopes. Using a spatula, the mesh is pressed against the insulation so that the glue spreads evenly onto its surface. After grouting and drying, you can begin finishing work. You can watch a video about insulating window slopes below.

Working with tides

Insulating the ebb of a plastic window is not a difficult task, so it can be easily done and will not require large amounts of money. It is important to carefully inspect the space and eliminate all the gaps that exist between the wall and the window. A metal strip is mounted on the low tide, which covers part of the opening and prevents it from getting wet. Under the bar you can place a small piece of insulation, which is firmly glued to the surface. All cracks are additionally filled with sealant.

Internal insulation of windows

The process of how to insulate windows with your own hands also includes interior decoration some nodes. These include:

internal slopes;
insulation;
windowsill.

Insulation will require special patience and care.

Internal slopes

The process of how to insulate the slopes of plastic windows from the inside is very similar to what was described above. Internal slopes require careful processing to achieve a pleasant appearance. It must match the chosen interior. The first step is to cut off the protruding foam, and also add it in those places where cracks have formed. The old finishing that was near the old windows is completely removed. The surface of the slopes is treated with a deep penetration primer and left until completely dry. The next step is to install drywall, plastic panels or putty and plaster.

Pay attention! After finishing, the slopes can be painted using water-based paint or finish decorative plaster, which is better than using plastic panels.

Windowsill

The window sill is an integral part of the window. For plastic windows, PVC window sills are used, which can be various sizes and execution. But we must unite them correct installation. First of all, you need to find out where the heat loss is going. The gap can be between the window and the window sill, as well as the window sill and the concrete part. In the first case, it is necessary to seal the gap with sealant. For a white profile, you can purchase white sealant, and for other colors, transparent is perfect if the required color is not available.

If it blows from under the window sill, then certain mistakes were made during its installation. In cases where complete dismantling of the window sill is impossible, there is an option using foam and try to blow it out problem areas. After the procedure, it is advisable to place something heavy on the windowsill so that the foam does not deform it and lift it up. If you have the opportunity to remove the window sill, you can additionally foam the junction of the window and the wall. A small layer of insulation is also placed under the window sill.

Advice! Insulation can be done using a special film. The process of such insulation is shown in the video below.

Insulation

In some cases, it may be necessary to replace the insulation on the window sash and frame. In plastic windows, replacing insulation is a simple matter. The use of adhesives is not required here. The rubber base is fixed in special grooves that are located on the plastic profile. The old insulation is disposed of. To make it easier to insert the insulation into the grooves of the sash or frame, it can be slightly moistened with soapy water. It is worth remembering that it must be laid in one contour. To do this, it is important to measure everything correctly and make a small reserve. It is better to opt for black insulation, which is also made of PVC. Insulation materials painted in a different color have a less durable structure, which leads to their rapid wear. In some cases, it is necessary to replace the rubber seal that holds the glass unit in place. To do this, you need to remove the retaining strips and the glass unit itself. The junction points are cleaned of dust and other dirt, after which the insulation is installed and the glass unit is installed.

Advice! Before replacing the insulation on the window, you need to try to adjust it or change it to winter mode. The illustration below shows how this can be done.

Resume

As you can see, plastic windows also require insulation. If, after calculating the costs of time, effort and money, it becomes obvious that during self-insulation You can earn a large sum, then it is better to hire specialists who will do everything themselves. When working to insulate a window, you must be extremely careful and follow safety rules, especially if the window is not on the first floor.

Ideally, insulation of window structures should be done at the installation stage. Of course, in this case, the total cost of each window will increase significantly (by about a third), since the price will be added to it thermal insulation material and carrying out work (if it is not done with your own hands). But the operational life of the entire structure will be extended. Moreover, you will not have to subsequently dismantle the windows (inside and outside).

But if no one took care of thermal insulation during installation, then you will have to do it yourself. Therefore, today we will talk about how to insulate double-glazed windows.

Design features of PVC windows

Any plastic window includes the following structural elements.

Profile.
Slopes.
Seals made of rubber.
Windowsill.
The glass unit itself.
Regulating fittings.

What is typical is that if a breakdown occurs with one of these elements, the window will blow out.

What materials will be needed?

For thermal insulation of modern double-glazed windows, it is preferable to use the same modern materials. In this case, one of the following options can be used as insulation for the window structure:

expanded polystyrene;
some “warm” mixture;
mineral wool;
polyurethane foam.

When choosing one or another of them, it is necessary to pay attention not only to the properties of each material, but also to the features of installation and further use (external and internal). The most convenient option is, of course, polyurethane foam, but under the influence of ultraviolet rays, temperature changes or even air, it is easily destroyed. That's why external works It is advisable to perform using “warm” mixtures. And to waterproof the plaster solution, you can use both painting and a primer with moisture-proof properties.

Pay attention! The only drawback in this case is that it is difficult to select consumable insulation material, for the installation of which it would not be necessary to dismantle slopes and other components. Only under such conditions can one accurately determine what the material should be and how much of it will be required.

For filling small cracks in areas where window profile adjacent to the window sill and other elements, sealant can be used. Even an ordinary housewife can handle this kind of work - you just need to follow the instructions for use indicated on the package.

What is the essence of thermal insulation?

Thermal insulation of double-glazed windows consists, as noted above, precisely in the slopes. If we talk about other structural elements, then only troubleshooting will be required. For example, drafts never appear due to the profile. And modern technological plastic, which is used in windows, is no longer wood; it is incapable of either “moving out” or drying out.

Plastic windows lose thermal energy if certain sections of the structure become depressurized. And if you do not want the cold to penetrate inside the room, then take care of insulating the slopes or start looking for the causes of the problems. Well, let's proceed directly to how to insulate double-glazed windows, and let's start with insulating the slopes of window structures.

7 ways to insulate windows for the winter

Previously, we gave several instructions on how and what is the best way to insulate windows for the winter; in addition to this article, we advise you to read this information

We are engaged in insulation of slopes

As you know, in metal-plastic windows the slopes must be plastic. The lining must be plastic, and it must be hard. What causes this? The point is that this material ideal for additional thermal insulation.

And here the opening formed between window frame and the surface of the wall, it is necessary to blow it out using polyurethane foam. Of course, there are other options - for example, insulating boards (they are made from basalt fiber) or foam insulation. Therefore, you can choose the material that is ideal for your current purposes.

The wall must be insulated both from the inside and outside. But in this case, the materials used will not only insulate, but also protect. The insulator itself is necessary to protect against various kinds external negative factors.

Correcting skewed sashes

As you know, in some cases even plastic window structures can shrink. And, alas, nothing can be done about this. As a rule, houses that were built most recently “suffer” from this problem. And due to shrinkage, accordingly, the sashes are slightly warped, which has a negative impact on the thermal insulation characteristics of the structure. But this problem can be solved - for this you need to debug the fittings.

What tools will you need?

The pressure of the sashes can be adjusted manually using special eccentrics. When the handle is turned, they move beyond the "calling areas". Such elements must be installed along the entire perimeter of the frame. And to ensure the tightest possible pressure, the eccentric must be turned strictly clockwise.

Each of the elements mentioned above has a special “picture”. If it is directed towards the street, this means that the clamp is loose. But if this pointer is directed towards the seal made of rubber, then the window sash is perfectly pressed against the frame structure.

A little about loops

Hinges in metal-plastic window structures also have their own mechanism, which is responsible for pressing. The device is adjusted using a special hexagon. Here you should be guided by one simple rule: If the tongue is pulled out strongly, the window sashes fit tightly. To extend this tongue, you need to twist the hexagon, while going counterclockwise. If the hinges in the window are located on the right, you need to turn the hexagon in the opposite direction. That is, here it is clockwise. It turns out that there is nothing complicated in this event - eliminating the distortion is easy and simple.

Pay attention! If the manipulations described above did not bring any results, and cold air continues to penetrate into the apartment, then, most likely, the problems are more serious. Here all you have to do is turn to specialists for help.

We continue to talk about how to insulate double-glazed windows. Now let's find out how to prepare windows for winter.

Changing the rubber seal

What is a rubber seal? Its main function is to ensure the tightest possible fit. window frame and shutters. To make it more reliable, it is made of rubber, so it does not allow cold air to pass through even if it is closed.

Given that proper care and periodic treatment with special mixtures, the sealant will last quite a long time. But only some owners of double-glazed windows do this, because this element is almost always hidden behind the doors. Well, only a few people know that the seal should be periodically treated with something.

For this reason, after about five years, the density of the element is lost. When the seal becomes unusable, it must be replaced. To do this, the windows are removed from the sashes, then the glazing bead is removed and the sealing material itself is removed. Replacing the latter is not difficult: the old seal is removed, and the new one is placed through the groove. If desired, the element can be fixed with glue. There is no need to worry about the difference in colors - the element can be either gray or black, but there are no special differences between them.

Pay attention! Extreme care should be taken when removing and installing the bead. The fact is that it is extremely fragile, so it is quite easy to break it. And if the bead is broken, the structure cannot be put back together.

What other insulation options are there?

It is worth noting that there are other ways to protect your home from the cold. Let's take a look at some of them.

Method number 1. Wool blinds

A non-standard method of thermal insulation of a window structure, but quite effective. Ordinary blinds must be wrapped with strips of woolen fabric, which will prevent the cold from entering the room.

Method number 2. Window sill insulation

Cold air can also penetrate through the joints between the elements of the window sill. Therefore, these joints should be carefully sealed. In addition, in case of improper installation, “black holes” may appear under the window sill itself, which means that the element must be dismantled, and the gaps between the block and the slab must be carefully processed.

For this purpose, the plugs are opened, the window sill is unscrewed with a screwdriver, and there you will find all the cracks (if any) that allow cold air to pass through.

Method No. 3. Application of heat-saving film

A double-glazed window can also be thermally insulated using heat-saving film - cheap, but at the same time effective material. It must be glued in such a way that no air bubbles remain under it, since not only the aesthetic indicators of the entire structure, but also the thermal insulation properties will depend on this.

And if you decide to use such a film, then it is better to take care of gluing it before you begin installing the double-glazed windows themselves. Although, in principle, this can be done after installation is completed.

Video - Gluing heat-saving film

Method number 4. Curtains

This may sound ridiculous, but curtains can be another way to insulate double-glazed windows. These elements act as a barrier to air, which means it does not let it through in winter (if it does penetrate through the window structures). Moreover, the air passing through the curtains even warms up a little.

Where does insulation begin?

Thanks to correctly carried out measures aimed at thermal insulation of double-glazed windows, you will get rid of all the mistakes that were made at the installation stage. If you want, you can even make some design changes to the windows - for example, install a window, replace the sashes that open with blind ones or vice versa, make adjustments to functionality, etc. And where does the thermal insulation procedure itself begin? First of all, from the choice of one technology or another, consumables, from developing a detailed plan for further work, and in order to do all this correctly, it is necessary to objectively evaluate general condition window system.

Pay attention! Despite the fact that work on thermal insulation of plastic windows can be carried out at almost any time of the year, it would be correct to do this during the warm period. In addition, there is another important condition– the weather should be dry and windless.

But, by the way, in cold weather it is extremely easy to detect where the cracks are located through which the cold penetrates into the room. Now let’s look at what “weak points” all metal-plastic structures without exception have. Such places include:

seal of the sash that opens;
emptiness under the slopes and window sill;
bead location area;
the place where the window frame adjoins other structural elements of the entire structure;
window fittings (all).

In addition, you should definitely pay attention to the width of the window sill. The fact is that it should not cover the heating radiators that are located underneath it. Yes, of course, a wide window sill is extremely convenient, but from a technical point of view it is not entirely correct.

Hire specialists or do everything yourself?

There are a number of defects, the correction of which is preferable to entrust to specialists. These defects relate directly to the metal-plastic structure and include the following.

Defects in the sealing material in the sash that opens.
Defects in thermal insulation along the contour of the entire window.
Malfunctions of window fittings or mechanisms.

The first point: you will need to insulate the ebbs and slopes of plastic windows from the outside, and this, of course, is not so easy to do, especially if we are talking about an apartment located above the second floor. Second: hand-made insulation will be a direct violation of the warranty conditions of both the manufacturer and the installer. Third: the quality of work will be guaranteed by hired specialists. Finally, the fourth important point: when executed repair work professionals will use “original” fittings and window materials.

But if the home master has sufficient experience and knowledge, then he will only need quality instructions regarding how to insulate double-glazed windows in order to select the most suitable technology for specific conditions. As for the thermal insulation of the window frame contour, this procedure can be done with your own hands. Moreover, you can insulate ebbs, slopes and window sills yourself. Today we will find out how to do this, but first, let's take care of all the materials necessary for the work.

As a conclusion

As a result, I would like to focus your attention on one more simple thing: if due to a double-glazed window it is lost thermal energy, then one of structural elements system has failed. And if you fix the problem, the window will again “acquire” the previously lost characteristics.

In fact, as noted above, insulation of window structures should be done at the installation stage. Of course, in this case, the total cost of each window will increase significantly (by about a third), since the price of thermal insulation material and work will be added to it (if they are not done by hand). But the operational life of the entire structure will be extended. Moreover, you will not have to subsequently dismantle the windows (inside and outside).

As for full thermal insulation, it is only necessary for the slopes and, perhaps, the window sill. No other measures to insulate the window are necessary in this case. Double-glazed windows already boast high-quality protection from the cold, since they were originally designed to provide a comfortable microclimate in the room.

Insulation of plastic windows can become a pressing issue if the room is not warm enough, it is necessary to improve its ability to keep it inside warm air and don't let cold stuff in. Usually you should start with the windows and insulation targets that have formed during the operation of the room. You can find information on how to do this in this material.

When might window insulation be necessary?

Plastic structures are usually sealed themselves and do not require any modifications, but the problem may arise for the following reasons:

The window was installed incorrectly, as a result of which gaps formed and the frame could become warped. If you notice this right away, you can contact the installer, but most often the defect is discovered after some time, and they no longer want to fix it for free. Special seals can help, but they are quite expensive. Knowing how to insulate plastic windows , you can do it yourself without spending additional funds for the services of masters.
The plastic window was damaged mechanically. Most often, when dealing with this problem, it is impossible to get by with improvised means, and the window has to be replaced. Insulation of the structure is a mandatory step in this procedure.

What time should I choose to carry out the work?

You can do the insulation with your own hands at any time convenient for you, but it is most comfortable to carry out such work in the spring or summer. The day should be dry and without wind: such weather contributes to better quality work, drying of consumables, and when opening the doors the living space will not freeze.

Advice: if you notice a draft or heat loss in the autumn or winter, do not postpone work until spring. Insulation and repair of plastic windows can be carried out as soon as possible if necessary.

In winter, you need to identify all the places where windows are blown out.

In winter, it is quite possible to carry out insulation work; the difference will only be in the complexity of its implementation. For example, at sub-zero temperatures, you will not be able to use sealant outside, as it simply will not dry.

Advice: if there is an urgent need to carry out work in the cold, a construction hair dryer can help out, which will need to thoroughly warm up the applied sealant seams. You can get by with frost-resistant polyurethane foam, and when it gets warmer, cover the seams with a sealing compound.

When working, you will inevitably have to open the window; in winter, this is associated with inconvenience for the occupants of the rooms, since the room will immediately become cold.

Using a hair dryer

How to insulate a window yourself?

It is worth paying attention that, even knowing how to insulate with your own hands , You may not be able to carry out some types of work yourself: for example, if the plastic of the window is severely damaged or work is required at a high altitude. In these cases, a wiser decision would be to invite a specialist who has the appropriate equipment to carry out the work.

You can independently carry out the following types of work:

Insulate from the inside. This can only be done from the outside if the window can be reached from the ground using a ladder or you have a balcony overlooking a window that requires insulation. In other cases, the services of climbers will be required.
Please note that when independent work you will void your warranty if it applies to windows.

You need to start work by insulating the contour of the frame, then insulate the internal and external slopes, the window sill and ebbs.

How to determine where it's blowing from?

The entry of cold air into a room is especially noticeable in winter, but finding exactly where it is coming from is not always easy. The following items should be inspected first:

Place for fastening the bead. It can move away and let the cold through.
A seal connecting the frame and the glass unit.
Accessories.
Window sill, slopes, place of contact between frame and wall.

To make sure you have found the crack correctly, you can use a lighter. When you bring the flame to the crack, you will notice its oscillation, which means that air enters the room from the street in this particular place. You can check this with your hand - bring your palm to plastic construction: You may feel a draft on your skin.

How to choose material?

Polyurethane foam

There is a variety of insulation available for plastic windows, so you should be careful when selecting it. Almost all insulation materials have approximately the same properties, the difference lies in price, ease of installation, strength, and some features. The following materials can be used as insulation:

Polyurethane foam. It is applied quite quickly and conveniently, reliably insulates cracks and joints, but has a drawback: it is susceptible to exposure to the sun and moisture, which is why it needs additional protection, for example, it can be covered with siding.
well suited for insulating slopes and window sills, it is quite soft, does not burn, but is afraid of moisture and requires protection of hands and respiratory tract when working with it.
Silicone sealant reliably seals cracks, protects against moisture and does not require additional protection. Useless if the gaps are very large.
Heat-saving film can be used in conjunction with any insulation and is suitable for all types of glass. Applied directly to glass and helps retain up to 80% of warm air.
– inexpensive option, which is convenient to work with. It holds its shape, does not allow moisture to pass through, but requires additional protection with siding, plaster, or any hard materials, since it is easily destroyed by physical impact.
Window slopes can be protected with construction tape. It insulates cracks well, but does not look aesthetically pleasing.
For outdoor and interior works often used cement mortar or special mixtures based on it or from gypsum. It is also advisable to cover them with a layer of plaster or water-repellent paint for additional protection and to create an aesthetically attractive design.
Special mixtures for outdoor use, containing substances that can repel moisture. They protect cracks well, blocking the access of cold air into the room, reliably insulate windows, repel moisture, and therefore do not require additional finishing.

Conclusion: insulating the window sill of plastic windows, slopes and eliminating cracks will help make the room warmer and save on heating. You can do the work yourself, but if you lack experience and equipment, you can contact construction companies, specializing in finishing window and door openings.

Heat losses in the house affect both the comfort of life in its monasteries and the payment of heating bills. Energy efficiency issues are also a priority in construction today modern buildings This aspect is given special attention. However, entering new apartment You can find some shortcomings, even in plastic windows, which are reliable.

When analyzing the condition of an old home for cold penetration, you can probably find more than one source of heat loss. This problem becomes especially relevant on the eve of winter. Ineffective home protection may be caused by design or installation errors.

Information on how to insulate plastic windows yourself will help you save on this operation without calling a professional, whose services can be expensive for the family budget. To repair, you only need desire and knowledge. When working you can use simple tool, which is found in the house.

You can analyze the condition of your apartment in preparation for winter for heat-protective efficiency at home, without turning to specialists for help. It is better to do this in cold or cool seasons when there is no wind outside. Why is this best way checking the window structure?

Because the difference in temperatures in the home and outside creates the prerequisites for the convection of air masses, which will help to correctly diagnose the problem and decide how to insulate plastic windows for the winter with your own hands. To identify hidden sources of cold penetration, you can create additional draft by opening front door or by turning on the exhaust ventilation.

An open flame is used as an indicator. You can take a lighter and matches. It's even better to use a candle. A stream of smoke reacts more subtly to air movement. Incense sticks, in extreme cases, a lit cigarette will become an accurate tool for searching for the smallest defects, poorly insulated areas through which the cold creeps into the home.

Carefully and slowly examine the following areas in front of the windows:

connection of the double-glazed window to the supporting profile;
sash vestibule to the impost and frame;
the connection point between the window system and the opening;
windowsill.

Having discovered places where the fire or a stream of smoke begins to fluctuate, mark them. Having completed the examination, a visual inspection begins. This will help to compile a list of works, and how to insulate double-glazed windows, slopes, and window sills will be discussed below. In some cases, the causes are easily identified. Simply replacing the seal is enough.

Plastic windows often need adjustment. But sometimes it is difficult to understand why it is blowing in this place, although external conditions are not visible. In some cases, the plastic window structure will need to be partially disassembled before insulation.

Reasons for heat loss through window systems

When replacing old wooden windows with modern plastic analogues, the installers promised that all problems were a thing of the past. But in practice it turned out that the apartment did not become significantly more comfortable. The vaunted sound insulation turned out to be not so effective, and is not much different from the time when they stood wooden windows. The inspection revealed places through which heat leaks out of the room in winter.

Before you start insulating plastic windows with your own hands, you need to identify the reasons:

If a heat leak is detected through the joint of the double-glazed window and the profile, then the problem is in the seal. The two contours of the gasket must form a sealed volume, the outer one is installed on the profile, and the inner one on the bead. The factory dimensions of the seats for plastic and metal-plastic windows are accurate and designed for the recommended thickness of the glass unit. Penetration of cold in this place means one of two things - incorrect dimensions of the double-glazed window or failed seals.
If heat escapes through the junction of the sash in the design of the window system, then there are 3 possible reasons. The first is the incorrect position of the sash, when its parallelism relative to the supporting frame is not maintained. The second is incorrect adjustment of the fittings. The locking mechanism does not provide pressure, leaving a gap that reduces the level of thermal insulation of the home. The third is a failed seal.
The penetration of cold through the cracks between the load-bearing structure of the wall and the window is one of the most common causes of heat loss. Incorrect installation, ignorance of the features of installing plastic windows leads to the fact that in the very first year of operation, the insulation loses all its declared qualities. There can be many reasons for unsatisfactory thermal insulation of windows. This includes poor-quality sealing of the technological gap, incorrectly made slopes, both inside and outside, the use of materials not intended for this type of work, and failed insulation for plastic windows. The coefficient of thermal expansion of a plastic structure is several times higher than that of a wooden analogue and metal-plastic system, therefore, such windows are installed taking this feature into account.
There are frequent cases of heat leaks in the window sill area. Often cracks and gaps in this area are hidden and difficult to detect, although they can be a powerful source of cold penetration into the home. The reasons could be: incorrect installation, as well as the quality of preparation of the seat, in particular additional bricklaying or installation of a special structure to obtain the required dimensions of the opening, into which plastic windows are then installed, the repair of which will subsequently become a labor-intensive and costly operation. Often the source of cold is under the windowsill.

Many of the above reasons can be eliminated independently with existing skills and experience. home handyman. When we insulate the window area ourselves, it is not necessary to have professional tool, specialized knowledge and skills. It is enough to approach this problem responsibly and carefully and correctly decide how to insulate plastic windows in a particular case. What materials to choose? What technology to use to ensure maximum thermal insulation for housing.

Technologies and methods of insulation of plastic windows

Having identified the causes, you can begin to eliminate them directly. How to insulate a plastic window quickly, effectively and inexpensively? If it is better to choose a cool time to search for places of depressurization, then repair and restoration procedures are carried out when the temperature environment allows the use of materials for which frost and humidity are unacceptable.

On the packaging of building mixtures and sealants, conditions of use are indicated that must be strictly followed in order to achieve desired result. It is better not to carry out repairs and insulation of plastic windows in winter, with the exception of some emergency operations, adjustment of mechanisms and when replacing seals.

The best double-glazed windows for plastic windows are made from energy-saving glass, but they also cannot cope with the task when gaps arise. The reason for this is the seal that has lost its quality. To replace it, it is better to remove the sash and carry out operations in a horizontal position.

In order to understand how to insulate plastic windows with your own hands, you need to familiarize yourself with the procedure:

the glazing beads are carefully dismantled;
the glass unit is removed;
old seals are removed from the grooves on the profile of the window system and glazing beads;
V seat a new elastic insulator is installed;
the glass unit is inserted into place;
when installing glazing beads, there should be pressure from the seal on the glass, that is, they are mounted with an interference fit;
The fit of the elastic elements along the entire contour on both sides is checked, and if vibration or movement of the double-glazed windows inside the sash is observed, then the wrong seal has been selected. In rare cases, a manufacturing defect may occur. The thickness of the glass unit is less than the permissible standards and will need to be replaced with a new product;
When the visual tightness test is passed, the sash is installed in the window block.

If the window uses non-energy-saving glass, and replacement is impossible due to certain circumstances, then you can increase the efficiency of double-glazed windows yourself. For this purpose, a special film with reflective properties is purchased. Insulating plastic windows in this way is economically and technologically justified. Following installation rules and recommendations, the film is glued to the surface of the windows from the inside, thereby significantly reducing heat loss.

Incorrect adjustment of the window system also causes many problems. Before doing it, you should make sure that the structure as a whole has the correct geometry, otherwise the work will be useless.

Deviations from the vertical of the side power profiles should not exceed 1.5 mm per meter. When measuring diagonals, the critical value defined by GOST R 52749-2007 is a difference in size of no more than 8 mm. Herself window design cannot have bends or deformations.

This is being checked building rule, metal ruler, straight line. The tool is applied to the horizontal parts of the structure. If both ends are tightly pressed to the profiles of the window block, and there are no gaps along the length of more than 1-2 mm, then the plane meets the standards. Otherwise, plastic windows will need to be repaired or reinstalled.

Now you can begin to adjust the position of the shutters relative to the frame. The window is slowly closed, making sure it touches the profile. If it occurs simultaneously along the entire length of the vertical line, then this position is considered correct.

Then check the size of the gap around the perimeter of the sash. It should be the same. If the conditions are met, but the window continues to blow, then most likely the problem is a worn seal, which is changed in the same way as during a similar operation with a double-glazed window.

If deviations are noticed, adjust the loops. Depending on the manufacturer's standards, the window adjustment screw may be a Phillips or hex screw. Use a screwdriver or wrench to adjust the window to a satisfactory condition.

Adjustments to the shutter mechanism of Euro windows are of no small importance. When the handle is moved from the “open” to the “closed” position, the sash should press tightly against the frame. The lever operates in a range of about 2 mm.

If, when closing the handle, the sash remains motionless, this means that the seal is in best case scenario only touches the box, although it should be slightly deformed, ensuring tightness.

The pressure is adjusted by an eccentric at the end. Use a wrench or a screwdriver to set the desired position. It is recommended to adjust plastic windows for winter every season.

Insulation of slopes

Window openings when installing plastic windows have some nuances. Since they provide greater thermal expansion, it is recommended to use only technologies that can withstand these changes. Filling the technological gap between the frame and the wall with concrete is not advisable even for a metal-plastic window, which has a lower coefficient of thermal expansion.

It is better to do this with polyurethane foam, which is also a good insulation material. This method of fixing a window system requires reliable protection from external influences, so special attention is paid to finishing on the outside. The sun and freezing destroy the structure of the foam. The slopes must overlap the profile of the window block. This promotes better insulation.

For quality thermal insulation protection Euro-windows subject to repair remove old materials.

Under new decorative finishing An additional layer of insulation is laid on the outside:

Mineral wool. The material requires additional protection from moisture. When insulating with mineral wool, a waterproofing layer is required;
Foamed polymers based on polypropylene or polyethylene. It is important to insulate PVC windows with these materials, leaving no cracks or gaps, eliminating the occurrence of cold bridges;
Composite materials. Sandwich panels are modern products, the production of which takes into account external influences. Additional materials no need for insulation. Composite panels will be good thermal insulation for finishing external slopes.

A metal-plastic euro-window on the inside requires rather decorative finishing. Having provided external protection, the opening with the block will become an insurmountable barrier to the penetration of cold into the home. The slopes are finished with insulating materials from the inside in cases where there is no sufficient thermal protection on the front side.

The sealing performed with waterproofing agents is not sufficient to create a comfortable environment in the house. Understanding the principles of installation of the system, a decision is made on how to insulate metal-plastic windows optimal method.

Window sill insulation

Inexperienced craftsmen do not pay close attention to this part O equestrian structures, assuming that insulation in this place is not necessary. The result of this error will be cold indoors in winter. Outwardly everything looks reliable, the window sill fits tightly to the plastic profiles.

The window slopes have been insulated, but cold air currents continue to penetrate the room. The reason may be an insufficient level of thermal insulation of the window sills below. The viewing location is not convenient; it is difficult to determine the source of heat leakage there. It is not for nothing that during the initial analysis of the condition of the home, it is strongly recommended to do a full inspection of all obvious and hidden defects.

Troubles can occur due to insufficient water protection on the outside. The leakage of water under the box and its subsequent freezing destroys the heat-protective layer, so the insulation of the window sill of plastic windows begins to be done from the outside. If necessary, remove worn-out materials and install new ones. But you don’t have to be satisfied with just replacing the thermal protection.

The layer should be reliably protected from moisture penetration. First, they insulate, then cover the material with a waterproofing material and install decorative trim or ebb. It is advisable to purchase a finished product for drainage. Such ebbs will become reliable protection on Euro-windows from getting wet and freezing of the openings in the lower part. Easily attaches to metal-plastic profile using sealants and screws.

If cracks have formed on the window sills with the frame, then repairs should be made. Having insulated problem areas, it is necessary to protect them. It is advisable to use plastic materials for this purpose, for example, silicone sealants. Then the windows will be insulated, waterproofed and not susceptible to the formation of new gaps due to the elasticity of the polymer.

Seal cracks dry construction mixtures inappropriate. They do not adhere well to a plastic surface, unlike wooden frame, where their use is justified. For the same reason, many masters get rid of old decoration traditional materials, preferring to decorate slopes with modern products.

If you insulate window unit mineral wool, then it is impossible to plaster on it without reinforcement. It is preferable to use sheet materials. The final decision on how to insulate the window sill of a plastic window is made based not only on technological, but also on aesthetic considerations, using similar techniques used when decorating the interior of the room.
