How to insulate double-glazed windows with your own hands. Preparing plastic windows for winter

Master of Architecture, graduated from Samara State University of Architecture and Civil Engineering. 11 years of experience in design and construction.

Perhaps, main reason installation of plastic windows is their ability to retain heat well in the room. However, for various reasons (improper installation, long service life, etc.) this property may disappear. IN summer period This is not so scary, but with the onset of cold weather, poor thermal insulation can cause big trouble. In order to correct this situation, you can insulate plastic windows for the winter with your own hands.

The main causes of thermal insulation failure

Some people may find it strange that cracks and distortions appear in modern plastic windows. However, such a problem does exist and occurs quite often. There may be several reasons for this:

• shrinkage of the house;
• improper installation of windows;
• loosening of the mechanism;
• seal wear.

One of the reasons for the cold in the house is the old seal

Depending on the reason, it is necessary to carry out thermal insulation. It is advisable to start work on a dry day in the warm season. This will greatly simplify the process. However, problems can often be too serious to delay. In this case, it is better to carry out insulation immediately.

Identifying problem areas

Before you begin insulation, you need to find and identify all the places that need thermal insulation.. Special attention attention should be paid to the joints, as well as the junction of the walls and the frame. You should also check the slopes and window sill. To identify areas where cold air enters, you can use a regular lighter. It should be passed over all possible places of blowing.

Damage to thermal insulation can cause condensation to form on the glass.

Condensation, frost or drafts may also indicate an area that requires insulation. Depending on the cause of the thermal insulation failure, you need to think about how to fix it.

Work progress

It is worth immediately noting that if you insulate plastic windows for the winter with your own hands, the warranty on them will automatically disappear.

If the owner nevertheless decides to carry out the work himself, it is necessary to find a place for a draft. Sometimes it happens that it occurs due to depressurization of double-glazed windows. Unfortunately, in this case, it will not be possible to carry out high-quality insulation on your own. In most other cases this is quite possible.

Insulation of slopes

If voids appear under the facing of the slope, this means that it needs to be repaired.. Finding them is quite simple: this is done by tapping on the surface. There is empty space where the sound would be louder.

The old insulation under the slope lining needs to be replaced

In this case it is necessary to remove facing material. There will be insulation underneath. In most cases, foam serves as insulation. If the problems are not too serious, it is enough to simply add material to the places where the voids form. When the insulation has already served its purpose, it must be replaced. The material can be very diverse: basalt wool, polystyrene foam, foam, etc.

After replacing the insulation, it is necessary to check the facing material. If the sheet has cracks or other serious damage, it must be replaced. It is better to use PVC or a plastic panel as cladding. Such materials not only look good, but also provide excellent thermal insulation.

You can choose polystyrene foam as a slope insulator

Insulation street slopes carried out the same way. However, if the apartment is located above the second floor, you need to contact professionals. It will not be possible to carry out the work without special equipment.

Replacing seals

In plastic windows, one of the fastest wearing parts is the rubber seal. After several years of use, it loses its properties and ceases to perform its functions. To increase the service life of the seals, you can use a special silicone grease (this is done twice a year). However, if the material has already worn out, it must be replaced.

To replace it, you need to pry off the glazing bead that holds the glass unit. After this it must be removed. Now the rubber is easily pulled out of its groove.

Replacement sealing tape will increase the thermal insulation of the window

Should be cut off new material(it’s better to leave a margin of 5-6 cm and cut it to the desired length after installation). Before assembly, you must ensure that the site is free of dirt. If necessary, the seal can be fixed with glue.

Setting the pressure

In modern plastic windows, the window sash pressure can be adjusted. This is done by rotating the eccentrics (located at the end of the sash). A 4 mm hex wrench is used for adjustment. There is a mark on the eccentric itself that helps determine the adjustment. If it is located on the street side, the pressure will be weaker.

Modern windows allow you to expose the summer and winter mode pressing the valves

Setting the position of the sash relative to the frame

There is another mechanism in the hinges of the sash, with which you can adjust the sash. Adjustment is carried out by tightening the screws.

Insulation materials

For high-quality insulation may need to be used additional materials. Here are some of the most common insulation materials.

How to stick thermal insulation film

Most common type energy saving film is heat shrinkable. It needs to be heated to stick. The technology for applying such material will be discussed below.

Energy-saving film significantly reduces heat loss in the room

Important! After gluing, it is extremely difficult to tear off the film. Therefore, before starting work, it is necessary to weigh the pros and cons.

Main mistakes during work

Many owners begin to carry out insulation work during the cold season. You shouldn't do this. And the reason is not only the inconvenience that such insulation will cause. Many formulations, the use of which may be required, require special temperature regime. Therefore, take care of how to insulate plastic windows for the winter, better in spring or in summer. If this does not work, you need to choose a windless and dry day for work.

Quite often, owners are somewhat negligent in searching for places where drafts occur. Under no circumstances should you do this. Even the smallest cracks and gaps can cause loss large quantity heat. Therefore, all of them must be eliminated.

When working with polyurethane foam, it is necessary to strictly maintain the thickness of the layer.

As you can see, insulating any plastic windows for the winter with your own hands is not so difficult. However, before starting work, you need to seriously think about whether it is worth doing at all. Most often, the cause of drafts and high heat loss is poor-quality installation of windows. If this is the case, then you need to contact the installer, who should correct the defects.

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 construction material so that the insulation process does not smoothly turn into protracted unfinished construction or, even worse, into protracted treatment.

Necessary materials

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

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

If the leaf comes out easily again, then it's all about sealing rubber sashes and frames. Over time they dried out and lost their elasticity. Needs replacement. We cut out a small piece from the sash, also from the frame (they are different in volume), and go to the nearest retail supermarket chain furniture fittings, 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

At poor quality installation external flashings and cornice, between them and the wall opening there remain unfilled cavities in which, when 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, or voids, you need to fill them with 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 a banal absence 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 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 silicone sealant inside and out, remove excess with a wet cloth.

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 along the window opening open flame lighters (palm). 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 soap solution glass surface. Apply the film, spreading it evenly. Rubber spatula squeeze out the remaining solution. Trim off excess film stationery knife along the edges of the glass. Carefully insert into the frame (sash), hammer in the glazing beads with a rubber hammer.

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

Warmth in a house or apartment is the key to comfort, coziness and well-being. To do this, we take you to our apartments central heating, we build heated floors and more. However, it is important not only to deliver heat to the house, but also to preserve it.

Most of the heat leaves our apartments through the windows, by insulating them you can significantly improve your living conditions during the cold season.

let's consider quick ways insulation of both modern plastic windows and old wooden ones. Let's start with the simplest and cheapest...

1. Do you want to insulate a window? - Wash him!

Heat leaves our apartments not only due to drafts, but also goes outside in the form infrared radiation.

Regular glass, being transparent to radiation of the visible spectrum, has low level transparency for infrared rays, transferring heat.

But contaminated glass, losing transparency in the visible part of the spectrum, significantly increases it in the infrared spectrum. Therefore, to preserve heat, it is enough to simply wash the window before the start of the cold season.

However, it wouldn’t hurt to do this in the spring either, so that less radiant heat penetrates into the apartment in the already hot summer.

The window should be washed inside and (necessarily!) outside with a product based on ethyl or ammonia. This will allow, firstly, to clean grease stains, which is especially important for the kitchen, and, secondly, to avoid stains left by dissolved salt in the water, remaining after the moisture evaporates.

In addition to the glass, we also need to wash the frames - we will glue seals, insulation, etc. on them. It doesn't stick well to dirt and falls off quickly. You don’t want to re-glue the seal in the middle of winter with the door wide open. open windows?

2. Traditional methods of window insulation

Effective way reducing heat loss is to install heat-shrinkable energy-saving film on inner side frames, parallel to the glass or double glazing.

This film has a double effect. Firstly, it prevents heat from escaping in the form of infrared radiation. Secondly, it creates an additional heat-insulating layer of air between itself and the glass. This usually gets rid of the " crying windows».

Installing thermal film is quite simple. On the frame, having previously cleaned and degreased it, glue it around the glass double sided tape. The film is usually sold folded in two layers. We separate the layers from each other and cut the film to the size of the glass, plus two to three centimeters from each edge.

We glue the film onto the tape so that its surface covers the entire glass. We try to stretch the film, but we don’t pay attention to the wrinkles. It is more important to ensure that the entire edge of the film “sits” tightly on the tape without “bubbles.” We direct hot air from a household hair dryer onto the film. Thanks to its shrink properties, the film itself will stretch and smooth out.

The view at the window with such a film, of course, is not so great, but it’s warm and dry.

New double-glazed windows do not heat. Why?

The seal on the frame is changed in the same way, after which the sash is installed in place.

The procedure for installing the sash is the reverse of the procedure for removing it:

The sash is placed on the lower hinge from top to bottom, then the parts of the upper hinge are connected away from you, the pin, lock washer and hinge cover are installed. We close the sash with a lock and check the quality of the work performed by testing the joint for drafts.

To ensure that the seal on a plastic window does not have to be changed every two to three years, this part requires proper care. The seal must be cleaned and lubricated at least once a year, but preferably twice, before the start of the cold season and at its end.

We wipe the seal on the sash and frame with a dry fluffy cloth to remove accumulated "rel="lightbox" href="/images/stories/kvartira/7-sposobov-uteplit-okna-na-zimu_8.jpg"> mud. Then wipe the seal with soapy water better cleaning and degreasing and wipe it dry. Apply silicone grease to a cloth (it can be purchased at any auto store) and rub it into the seal. This simple procedure will protect the seal from drying out in the heat and “stiffening” in the cold, allowing it to retain its properties for a long time.

6. We insulate slopes and window sills

For some reason, some people forget that a window is not only glass, frame and sashes, but also slopes and window sills. What's the point, from the very better window, if from under the window sill it “siphons” all the way? Of course, it’s better if, along with replacing the window, you also replaced the slopes and window sills with modern designs made of PVC, however, it is during their installation that installers often “slut”, knowing that the customer will pay the main attention to the frames.

Inspect the places where the slopes meet the concrete. If large cracks are found, we fill them with tow or foam rubber and cover them with alabaster on top, or fill them with polyurethane foam, which will need to be straightened and sanded with sandpaper after drying. We finish sealing the cracks with construction sealant.

If the initial inspection reveals nothing, perform a more thorough test using a burning match or a wet finger. If “cold bridges” are detected, you need to “tap” the cladding layer. A dull sound compared to neighboring areas will indicate the presence of voids under the cladding layer. In this case, remove the cladding and seal the cracks using the method described above. Do it, really" rel="lightbox" href="/images/stories/kvartira/7-sposobov-uteplit-okna-na-zimu_9.jpg"> , should be done in the warm season, because polyurethane foam and finishing construction mixtures do not work well in the cold.

You can make slopes yourself from inexpensive materials at hand, for example, from polystyrene foam, while saving on PVC slopes and the services of installation companies. To do this, you will need foam panels at least three centimeters thick, foam glue (for example, “ceresit”) and cement mortar.

This work, however, is not the easiest, fastest and cleanest. You should think twice about whether it would be better to invite a professional. But if you decide for yourself, then in brief the following awaits you:

The sides of the window opening and part of the adjacent wall should be opened to the base - brick or concrete. This is done in order to embed the insulation layer into the wall. A lot of surprises can await you here, in the form of boards walled up by builders, tow rolls and other “insulation materials”. The holes will be impressive. A fair chunk of the adjoining wall's plaster may even fall off, so be prepared for plastering work of an appropriate scale. To ensure reliable adhesion of the future slope to the base, you can secure the reinforcing network with dowels (plastic - so as not to conduct the cold).

Having mixed the cement mortar, we apply a layer of plaster to the window opening and to the wall, to the width of the future slope (about 20 cm) from the opening. You can add clay to the solution. This will give it additional viscosity, and it will be easier to plaster the vertical surface of the walls. We achieve a smooth surface and let the plaster dry well.

However, if you are confident in the reliability of the existing layer of plaster, then you can simply carefully scrape off the wallpaper, paint, or other decorative coating walls, prime and level the surface with a small layer of putty.

" rel="lightbox" href="/images/stories/kvartira/7-sposobov-uteplit-okna-na-zimu_10.jpg"> Next, apply glue to the foam panels with a notched trowel and press the panel to the surface, holding for 10-20 seconds until the glue “sets.” First, we glue the foam to the vertical part of the wall and slopes. The seams between the panels are carefully covered with the same glue. Similarly, we install the panels on the horizontal part of the slope in window opening.

As an alternative, you can use polyurethane foam. It fills the voids in the slopes well, holds tightly to the base, and the insulation itself can be reliably “glued” with it. It’s just that it’s a little expensive, and you need a lot of it (a large bottle for a double-leaf window may not be enough).

You can cover the foam with plasterboard or thin plastic panels, placing them again on glue.

I repeat, the surfaces are complex, there are many angles. Professionals use other insulation materials and install special cladding panels. But if you need to save money or want to do everything yourself, you can definitely try it.

7. Window insulation using Swedish technology

If installation modern window from a PVC profile is too expensive for you, or is not suitable for some other reason, insulate the usual wooden window possible using newfangled Swedish technology. This sonorous name was given to the technology of window insulation using a Euro-strip grooved seal, Swedish made, although analogues produced in countries have already appeared on the market of Eastern Europe.

The technology requires the use of a rather specific tool, which not every home craftsman has, and experience in handling it is also required. So for this service it is better to turn to 7 ways to insulate windows for the winter: Photo 11" rel="lightbox" href="/images/stories/kvartira/7-sposobov-uteplit-okna-na-zimu_11.jpg"> specialists. But all the work is done quickly, so this method is quite suitable if winter “suddenly crept up unnoticed.”

To install the seal, the window sash must be removed. In the place where the sash adjoins the frame, a groove is made with a milling cutter, into which a tubular profile is placed with a special roller, which takes the shape of the groove. Additionally, the connection is sealed with silicone sealant. If desired, insulation using a Swedish profile can also be done inside a double frame. The balcony door is insulated in the same way.

7 ways to insulate windows for the winter: Photo 12" rel="lightbox" href="/images/stories/kvartira/7-sposobov-uteplit-okna-na-zimu_12.jpg"> « Swedish technology» also includes adjustment of sashes, frames and balcony doors, however, this must be done in any case, regardless of the installation of Swedish seals.

The effectiveness of such insulation is little better than traditional sealing, but it allows you to freely open windows and vents during the winter for ventilation.

We looked at the most common methods of insulating windows that do not require major repairs. I hope our tips will help add a little warmth to your life.

It's no secret that it goes through the windows great amount heat from the premises - this is especially noticeable in winter period. Consequently, it is these structures that need protection, and the sooner it is done, the better. Fortunately, similar works You can easily do it yourself, and if you don’t have time for it, just hire specialists. Even our distant ancestors were aware of how to properly seal cracks in window structures - their houses were warm even in severe frost, but little wood was required for heating. However, insulating plastic windows for the winter is somewhat different from the traditional solutions that were popular decades ago; the technologies are different nowadays, and modern approaches to solving problems are also chosen.

We insulate plastic windows

First of all, you should know that when performing insulation, you may need to do it yourself. Such a task can be completed without problems, especially if you take into account the recommendations and tips on the topic. However, first things first. Despite the fact that manufacturers always assure the reliability of their products, even quality window Insulation may be required.

Most cheap way to protect yourself from the cold - cover the opening with some dense material that can retain heat. Previously, for example, blankets were used for this, but today such a solution can only be applied to wooden windows. Modern remedy for double-glazed windows - special colorless polyethylene film, which is fixed to your structure. This method guarantees effective insulation making plastic windows with your own hands, you don’t need to dismantle anything when working, which is very convenient.

Blinds and insulation

Some people choose blinds to minimize heat loss through double-glazed windows. are not affected. An important point - if you insulate plastic windows for the winter using this method, you should definitely stick strips on the blinds wool fabric, this is the only way to achieve the desired effect.

Electric glass heating

If cheap options are not satisfied, it’s time to pay attention to an expensive means of insulation - installing a system that will provide electric heating to the windows. Today, you can buy many different heaters specifically for double-glazed windows - they are installed on window sills. There are also special incandescent coils (they are glued directly to the glass). The right way Don’t worry about the cold weather - install a metal-plastic window in your apartment, the design of which consists of at least three glasses. One of them will definitely be energy saving. It is beneficial to use such glass - the heat-saving characteristics of the entire system are significantly increased. If you do repairs and insulation of plastic windows this way, your double-glazed window should have thermal break elements, which should also have metal inserts. The space between the glasses is usually filled with krypton or argon. In general, this is a very expensive solution, but you can forget about drafts and frosts for a long time (of course, if there are no more vulnerable spots in the house).

Why do you need to insulate slopes?

When old wooden windows are replaced with modern plastic, they usually expect excellent protection from various negative factors: dust, noise, cold. Indeed, the PVC profile pays off at first, but then it still begins to let in moisture and cold. This happens due to wall subsidence, as well as depressurization of seams. Of course, this situation will not make your home comfortable, and you will have to insulate the slopes of plastic windows. What is typical is that these works are performed both inside and outside the premises. For everything to go well, you need to install additional thermal insulation and protective layers. For this you need some materials:

• extruded polystyrene foam;
• Styrofoam;
• mineral wool;
• isover (fiberglass);
• sandwich panels.

These materials are usually sold in the form of slabs. One more question - which one is better to choose if you do the insulation of plastic windows yourself? It all depends on the size of the gaps. For example, if they are at least 0.4 cm, fiberglass is also perfect, the thickness of which is usually in the range of 20-30 mm. When the gap is narrow, choose polyurethane foam or mineral wool.

Plastic windows are not the most difficult task, if you have at least minimal construction skills, there will be no problems.

In what cases is it necessary to insulate slopes?

If the walls in your room are multi-layered and carefully laid with various insulating materials that reach window box, insulating plastic windows for the winter is not mandatory procedure(if there were no precedents). This wall structure is reliable protection from freezing. But if they are single-layer or the house is made of panels with stiffening ribs, you will still have to make thermal insulation - there’s nowhere without it. Special thermal liners are placed along the slopes.

How slopes are insulated

The material chosen for thermal insulation is fixed to the surface of the window opening. The seam that is created during installation must be closed, and the window frame must be partially covered. Drywall is installed on top of the material, its surface is first puttied, then painted - to achieve maximum effect. If you use extruded polystyrene foam, it is not necessary to use gypsum board.

Sheets of insulation are glued along the top of the slopes; moreover, they should be secured on top plaster mesh. On her thin layer apply cement-sand mixture, then - produced finishing putty to consolidate the result.

Foam insulation

Another technology that deserves attention if you are insulating plastic windows for the winter is the use of foam plastic. When the frame has already been installed, the opening is plastered using a cement-sand mixture. It is important that the surface is well dried - after that a layer of foam plastic is glued onto it, the thickness of which does not exceed 5 mm. Afterwards everything is puttied and painted. This technique provides excellent protection from cold air - now it will be much more difficult for it to get into living rooms from the street. The window opening is often insulated using expanded polystyrene using the same method, and plaster is applied to it - a very decent result is obtained.

Swedish technology

IN Lately many choose for home Swedish insulation windows The name of this method arose due to the material used in the work. The tubular seal is made of silicone rubber - it is made in Sweden. As the manufacturers say, this material very durable - up to twenty years, while it does not lose performance characteristics even over a wide temperature range. It is not afraid of the effects of paints and dirt.

Performing Swedish window insulation yourself is not the best simple task. You can’t do without professional skills here; you should also have at hand special tool. It is difficult to make a cut around the perimeter with a milling cutter, especially if the result is to get a groove for rolling up the seal - so that over time the material does not peel off or fall out. It is best when specialists insulate plastic windows in your home using this method. The price may vary - it all depends on the region, but the result of the work is worth the money. In addition, the price includes various services: sashes, adjusting the groove for the seal, placing tubular silicone in it, and, if necessary, adjusting the plastic window. Not everyone can do all this with their own hands, only an experienced builder.

When to make adjustments

The insulation of plastic windows for the winter has been completed, now is the time to think about adjustments. When it is necessary?

• If the window sash sags (due to this plastic frame touches the sash bottom). You need to adjust the vertical or horizontal plane.
• Due to the displacement, the middle sash part touches the frame. To get rid of this, the problematic part is evenly shifted to one side.
• When air enters through the seal. In this situation, the sash pressure is simply adjusted.
• If the handle is loose. If this problem occurs, turn the plate located at the base, then tighten all the screws.
• The handle turns too tight. Setting up is easy - for this purpose use machine oil. Cotton swabs, as well as any brushes, are perfect for lubricating eccentrics, hinges and clamping mechanisms.

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.

1. Profile.
2. Slopes.
3. Seals made of rubber.
4. Windowsill.
5. The glass unit itself.
6. 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 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.

Note! The only drawback in this case is that it is difficult to select consumable insulating 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 sealing small cracks in places 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 is known, in metal-plastic windows slopes must be plastic. The lining must be plastic, and it must be hard. What causes this? The fact is that this material is ideal for additional thermal insulation.

And here the opening formed between window frame and the surface of the wall, you need 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 influence 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 reverse side. That is, here it is clockwise. It turns out that there is nothing complicated in this event - eliminating the distortion is easy and simple.

Note! 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.

Note! 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.

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 double glazed windows, will allow you to get rid of all the mistakes that were made at the stage installation work. If you want, you can even add some design changes– for example, install a window, replace the doors that open with solid 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, Supplies, from developing a detailed plan for further work, and in order to do all this correctly, it is necessary to objectively evaluate general state window system.

Note! 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 spots» available to everyone without exception metal-plastic structures. 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 point is that it shouldn't cover heating radiators, which are located under 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.

1. Defects in the sealing material in the sash that opens.
2. Defects in thermal insulation along the contour of the entire window.
3. Malfunctions window fittings or mechanism.

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: by doing repair work professionals will use “original” fittings and window materials.

But if House master has sufficient experience and knowledge, then he will only need high-quality instructions on how to insulate double-glazed windows in order to select the most suitable for specific conditions suitable technology. 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.
