How to insulate a plastic window. How to insulate plastic windows Technology of insulating plastic windows

In this article we will figure out how to insulate plastic windows for the winter with your own hands in order to enjoy a pleasant temperature in the house during frosts.

What determines the need for insulation?

By installing polyvinyl chloride (PVC) windows, which are modern high-tech structures, many consumers are confident that such products are guaranteed to protect their homes from the cold. Theoretically, this is how it should be. Properly installed plastic windows perform their task for a long time - they retain heat. But even the best PVC profiles lose their properties over time performance characteristics and the level of thermal insulation of the room decreases. If plastic window structures were initially installed in violation of technology, problems with them will begin quite quickly.

Insulation plastic windows any manufacturers for the winter is usually required due to:

  • natural wear of the seal;
  • linings extending from the glass unit;
  • violations of the geometry of windows caused by shrinkage by the wall of a residential building;
  • loose adjustment locking elements PVC structures;
  • wear and tear of the materials from which the products were made;
  • improperly installed window sill or slopes.

Problems with polyvinyl chloride structures are solved in two ways. You can call specialists from a company that deals additional insulation, sale, window repair. And they, in a short time, professional level will do everything necessary work. Comfortable? Without a doubt. But the problem is that the cost of the services of such specialists is often similar to the cost of purchasing a new PVC profile. Not every person will agree to pay that kind of money. In this case, it makes sense to figure out how and with what to insulate plastic windows. And try to complete all the activities yourself.

What kind of work can you really do yourself?

At home, it is impossible to eliminate serious defects in plastic windows. With your own hands you can insulate only the following elements of a PVC product:

  • internal slopes;
  • contour window frame;
  • ebb and window sill outside the room.

At the same time, you should not forget about safety precautions. For example, it is undesirable to carry out external work in cases where windows are installed in apartments above the second floor of the building. Important nuance. Insulation should be done exclusively in warm weather. Choose a dry, windless summer or spring day, understand the technology for performing the work in advance, and stock up the necessary materials and tools. And only after that begin to restore the operational properties of the windows.

At the first stage, you need to clearly determine which areas of the window structure require insulation. Bring the lit lighter to the window profile and begin to move it around the perimeter of the PVC product. In places where the flame begins to fluctuate, insulation needs to be done. The most vulnerable areas are the joints of the frame and wall surfaces, slopes and ebbs. If there are significant leaks, you won't even need to use a lighter. The wind blowing will be felt with an open palm.

You should also analyze the condition window fittings. It often causes the seal of a plastic structure to break. If you see any defect or malfunction on the fittings, simply install a new part. You may not need to take any further steps after this.

Be sure to examine the condition of the profile clamping mechanism. It is this that ensures the tightness of the window. Pay attention to the rubber seal. During operation, the gasket installed on the PVC structure loses its density (the phenomenon is due to climatic conditions and mechanical stress). This leads to a significant reduction in the volume and thickness of the elastic. If the gasket has cracks, gouges, or wrinkles, it should be replaced immediately. In the next section we will describe in detail how to restore the tightness of a window profile.

We reanimate thermal insulation - the procedure for different situations

Let's start by replacing the worn-out sealing gum.If this is the reason (the gasket has become thinner and lost its original elasticity), proceed according to the following scheme:

  1. 1. Dismantle the glazing bead along the area of ​​the structure with the detected flaw.
  2. 2. Remove the linings and carefully remove the glass unit.
  3. 3. Pull out the old seal and install a new one. The length of the latter should be 40–50 mm longer than the initial piece. You will cut off the extra centimeters after installing the new elastic band. Its installation should be done without tension or excessive force.
  4. 4. Install previously dismantled parts (glazing beads, linings, package) in reverse order.

Before installing a new gasket, remove dust from the window grooves, wash them thoroughly and dry them. Then installing the seal will not cause any difficulties. He will stand up like a glove.

In cases where the seal looks intact, proceed to adjust the clamping mechanism. To perform this operation, you need to stock up on a special window key. First, inspect the glass unit. Lightly press it and release it. If it does not wobble too much, strengthen the clamp with silicone sealant. Such a composition should not include acids that can adversely affect rubber compressor. If the double-glazed window is noticeably wobbly, you will need to adjust the special. with a trunnion key - metal cylinders fixed in slots. Loosen any existing bolts. And then tighten the hooks that hold the cylinders.

In some cases, it is necessary to adjust the adjusting locks on the windows. Two screws should be found in the area where the plumb lines are located for the PVC structure. One of them is responsible for the level of pressure on the sash, the second holds it in a given position. Take a screwdriver, loosen (completely) the fixing screw, and then gradually tighten the clamping element (clockwise). After tightening, close the window, arm yourself with a lighter, and check the structure for drafts. If the flame fluctuates, slightly tighten the adjustment screw again. Carry out the specified sequence of operations until you are sure that there is no draft.

Insulation for PVC windows – which one to choose and how to use?

Additional thermal insulation of plastic window designs can be made with different materials. As a rule, for these purposes they use:

  • Mineral or stone wool. Slightly outdated, but quite effective heat-insulating materials for plastic windows (especially their window sills).
  • Construction foam. This insulation should be used with caution. It cracks and then collapses under the influence elevated temperature and the rays of the sun.
  • Silicone sealant. Easy-to-use material with high energy-saving properties.
  • A primer with water-repellent characteristics (for example,). An additional layer of paint must be applied to it.
  • Styrofoam. Used for filling gaps in slopes.
  • Heat-saving film. Modern way insulation plastic structures, which is quite popular among home craftsmen.

Let's see how to use energy-saving film. This insulation option guarantees high-quality results with little effort. You will need a hairdryer, tape (required double-sided), sharp scissors, or better yet, a stationery knife. Insulate the window using a simple algorithm. First, remove dirt and dust from the metal-plastic structure using a damp rag, and degrease the cleaned areas. After this, cover the window frame with double-sided tape.

Cut the energy-saving film to the required dimensions using a stationery knife. Attach the resulting strips to tape. All that remains is to spray the glued insulation with hot air from a hairdryer and, if necessary, remove air bubbles from under the film (carefully pierce them with a knife). Described technique for owners plastic products is the most profitable in terms of financial expenses.

Internal and external slopes of windows are insulated, as noted, with foam plastic, as well as three-layer special panels, pieces of extruded polystyrene foam, and fiberglass materials. Small cracks (up to 4 cm wide) can be sealed with polyurethane foam. Internal slopes They are insulated with polystyrene foam like this: treat the problem area with a primer, plaster the surface, install a foam sheet using mounting adhesive, wait for the insulation to set, then apply a layer of putty on top. Some home craftsmen additionally cover the thermal insulation layer with plasterboard sheets.

Outside, the slopes are insulated a little differently. Treat them with a primer. In this case, it is necessary to use formulations with antibacterial additives. Then you plaster the surface (if it is smooth, you can do without this step). Cut a slab from a piece of polystyrene. It should cover the entire slope. Mount the slab using metal corner and dowels (in addition, you can use mounting adhesive). Install a fiberglass mesh over the resulting structure. It is usually placed on an adhesive composition. After the slope has dried, you need to paint it with water-based paint.

Preparing a window sill for winter is a simple matter!

Separately, I would like to say a few words about how to insulate the window sill of a plastic window. If this element of the PVC structure is installed poorly, there is a high probability of the formation of a wide and deep crack.

Also, illiterate installation causes the appearance of relatively small gaps between the contacting parts of the window sill, under which it is often placed. In both the first and second cases, cold air will begin to penetrate into the home. This cannot be allowed. Do the following:

  • carefully open the special plugs on the windowsill;
  • use a screwdriver to unscrew the fasteners;
  • remove the window sill.

All problem areas that were not previously visible under the dismantled structure will open before you. Seal small gaps silicone sealant or polyurethane foam. Large holes should be filled with stone or mineral wool, covered with a plastic sheet on top and secured with the latter. After this, put the window sill in place. Now your home will be much warmer.

If the cold enters the house through a plastic window, do not rush to call the specialists. As you can see, many jobs can be easily done with your own hands, achieving good results. Try to bring comfort and warmth back to your home yourself!

Over time, even PVC windows begin to lose their airtightness. Therefore, in Russian winter conditions they need additional protection and adjustment. In this article we will look at how to insulate plastic windows for the winter with your own hands.

Before insulating windows with your own hands, you should identify “problem” areas. Over time or if installed incorrectly, metal-plastic structures can begin to let in cold air. This is most noticeable in winter, so identifying the causes of cold air is easier at this time of year.

Cold air can enter the room through:

  • Accessories.
  • Places where frames adhere to slopes, walls or window sills.
  • Rubber seal (between frame and glass).
  • Fastening strip (“glazing bead”).

You can determine where the gap is located in the old proven way: take a lighter (a simple gas lighter) and bring it to all of the above elements. The flame will begin to fluctuate as air leaks. The main thing is not to bring it too close to the frames, so as not to melt the plastic.

Main scope of work

Preparing plastic windows for winter with your own hands includes replacing damaged elements. Many Russian manufacturers don't spoil high quality consumables (seals, etc.). Therefore, they have to be changed regularly in order to block cold air from entering the apartment.

We replace the glazing bead

If an air leak is detected in the bead area, it must be replaced. This is done very simply:

  • Using a narrow spatula (or, in extreme cases, a knife), pry up the glazing bead and carefully pull it out.
  • We buy a new one. It is necessary to select it according to the size of the window.
  • We put the glazing bead in place of the old one and rubber mallet, lightly tapping it in.

The cost of this element is low - in the range of 100-200 rubles, but it determines whether street air will enter the room.

Replacing the fixing pad

The lining loses its elasticity during use. This is primarily due to temperature changes. Replacement is carried out as follows:

  • We remove the glazing beads (side ones first).
  • We take out the linings.
  • We dismantle the double-glazed window.
  • Remove the old tape.
  • Cut out a new one. In this case, you should leave a margin of a few centimeters.
  • We lay a new tape. There is no need to put in any effort.
  • We collect all the dismantled elements.

We eliminate leaks in the frame area

If there are leaks in the frame area, then the problem lies in the clamping elements. There are two possible reasons for this.

  1. The sash is not pressed well. To fix this, you need to use a hex wrench (or a screwdriver with an appropriate attachment) to tighten the flaps more tightly. Simply insert the hexagon into the corresponding slots and scroll until the frame is properly pressed.
  2. The seal fits poorly. In this case, we proceed as follows:
  • Remove the layer of old sealant.
  • We clear the installation site of all kinds of debris.

Tip: if there are glue residues or other stubborn stains, use a special PVC surface cleaner.

  • Place the seal strip in the appropriate grooves. The length of the cut piece should be perfect in size.
  • Lightly pressing the strip, glue it.

It is better to purchase the seal from the manufacturer or window installer. Buying low-quality models will make insulating plastic windows a pointless task.

Additional scope of work

Other effective measure- sealing existing joints and seams with heat-insulating material. She happens to be the only solution, if the double-glazed windows are installed incorrectly.

We study materials that can be used

There is diversity in this market segment. You can insulate plastic windows for the winter using the following materials.

  • Polyurethane foam. It is most popular due to two advantages: affordable price and high installation speed. However, it quickly deteriorates as a result of temperature changes and exposure to UV rays.
  • Mineral wool. It is fire resistant and environmentally safe. It is usually used to insulate a window sill or large gaps between a window and a wall.
  • Silicone sealant. Pros - low price and reliability. The downside is poor thermal insulation.
  • Special film. It is transparent and is glued onto the glass unit itself, which allows you to retain more heat (up to 70% of it sometimes escapes through the glass).
  • Polystyrene foam is the cheapest option. It can be used to seal seams in slopes.
  • Construction tape. It is usually glued over sealant or polyurethane foam in order to improve thermal insulation characteristics.
  • Warm mixtures. Used for external sealing of seams and joints.

Film

Cover the glass with the above-mentioned film. It is sold in rolls, so it is convenient to cut. We do everything in this sequence:

  • We clean the windows.
  • We cut the film to the size of the window. You need to leave an allowance of 1-2 cm for each side.
  • Filming protective layer.
  • We wet the glass and film.
  • Glue and level it using a plastic spatula.
  • Trim off the excess with scissors or a cutter.

Exterior works

Before the onset of cold weather, the outer part of the facade should also be prepared. To do this, we seal the external slopes and cracks (if any) using a warm mixture. This can only be done at positive temperatures.

Sealing seams and cracks

If even small cracks are observed, they must be sealed with any of the materials listed above. It is better to first plug large joints with cotton wool (or similar material) and fill with foam on top.

Conclusion

The problems listed in this article can only arise if the double-glazed window was installed incorrectly. The exception is if you have had them for a long time (more than 10 years). Therefore, if problems arise in new windows, first of all call the installer - he is obliged to correct his shortcomings.

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 of infrared radiation.

Regular glass, being transparent to radiation of the visible spectrum, has low level transparency for infrared rays that transmit 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 it 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. After cleaning and degreasing the frame, apply double-sided tape around the glass. 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 pressed from top to bottom onto bottom loop, then, moving away from you, connect the parts of the upper hinge, install the pin, lock washer and hinge cover. 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 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 plaster vertical surface walls will be easier. 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 facing 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, produced in Sweden, although analogues produced in other 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 the fitting 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.

Large heat losses during the cold season make you think about how to insulate plastic windows for the winter with your own hands. In many cases, it is worth inviting professionals to do this, but there are problems that can be easily fixed on your own.

In contact with

Why do you need insulation?

Most of the heat loss in the house occurs through window openings. The roof, floor and walls are significantly inferior in this indicator.

Low temperature is uncomfortable, significantly reduces the quality of life, not only the same home comfort. Along with the heat, money spent on utilities or heating natural resources also leaves the home.

Therefore, practical owners think about plastic window structures in a timely manner. This will reduce housing maintenance costs, will make life more comfortable.

  • plastic effective material;
  • affordable price;
  • ease of use;
  • susceptible destruction under the influence of ultraviolet light, needs protection with facing material;
  • budget option for insulation;
  • over time it collapses and “sags”, is sensitive to temperature changes;
  • better choice of material high density, it is more resistant to destruction;
  • low safety class; reliable cladding is required.

Basalt (stone, mineral) wool:

Penoplex:

  • a modern version of insulation made from extruded polystyrene foam, endowed with excellent properties;
  • superior to foam both in characteristics and price.

A new inexpensive, easy-to-use material is gaining popularity - thermal insulation. film for insulation of plastic windows. It is glued directly to the glass and allows you to effectively insulate damaged double-glazed windows in any plastic windows. Energy-saving properties are provided by a special metal-containing coating that reflects infrared radiation and does not release heat. Strengths:

  • electrostatic (does not attract dust);
  • tolerance to household chemicals;
  • transparent, thin, invisible canvas;
  • does not glare;
  • good size range;
  • affordable price;
  • ease of application.

Among the few disadvantages is a short service life; after 2 years it will require replacement.

A new inexpensive, easy-to-use material is gaining popularity - heat-insulating film for insulating plastic windows.

How to stick film

With the help of energy-saving film, you can achieve noticeable results in heat conservation. Let's consider the algorithm for applying this material to a plastic window:

  1. You will need a film slightly larger than the window block.
  2. For fastening take a special transparent Double-sided tape, cut off with a small margin.
  3. Thoroughly clean and wash the surface of the glass and plastic elements of the window.
  4. Place a strip of adhesive tape around the perimeter of the frame.
  5. Straighten a piece of film (cut with an allowance of 1.5-2 cm on each side).
  6. Remove the protective layer from the tape on the top bar.
  7. Apply the top edge of the film to the tape.
  8. Stretch the coating so that it does not come into contact with the glass; make sure that the tension is not too strong - the film breaks.
  9. Starting from the top, gradually remove upper layer from the adhesive tape, apply the film to it.
  10. Secure the bottom edge of the covering.
  11. Using a regular hairdryer, heat the film evenly over the entire area.

Cover a large window area with new material using two people. Remember, during the process of sticking the film should not come into contact with the surface of the glass unit, it should not be stretched too much to avoid tearing.

As a result of the last manipulation, the film is stretched, leveled, and becomes transparent and matte. So in a simple way Any owner can insulate double-glazed windows in plastic windows.

The film should not come into contact with the surface of the glass unit.

Main mistakes

When carrying out work on sealing plastic windows that have lost their heat-protective properties with their own hands, inexperienced owners make typical mistakes:

  • dismantle, change structural elements, components and fittings during the manufacturer's warranty period and installer; V guarantee period Invite specialists to eliminate defects;
  • when replacing mechanisms and accessories, “non-original” repair kits are used;
  • begin to eliminate defects with the onset of frost; it is better to do repairs in the warm months or, at least, on a dry, windless day;
  • show negligence in identifying gaps and voids, seal seams and voids poorly.

Important! Failure to comply with the technology for insulating plastic windows and the use of low-quality materials leads to constant problems and discomfort for residents.

Useful video: insulating a plastic window using a special tape

Take care of the “health” of your windows. The weather in the house will always be good if its thermal protection is in order. Any, even the smallest crack will cause a large heat leak. Conduct a timely audit and eliminate defects, following simple but very important rules.

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. Therefore, it is advisable to carry out external work 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 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 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 the window frame and the wall surface must be blown 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 too far, then 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 between the window frame and sashes. 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 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, 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 must 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” everyone without exception has. 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 of window fittings or mechanisms.

The first point: it will be necessary 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're talking about 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.
