Ideally, the insulation of window structures should be engaged in the installation phase. Of course, in this case, the total cost of each window will increase significantly (approximately a third), as the price will be added to it heat insulating material and work (if they do not work with their own hands). But the operational period of the entire design will be extended. Moreover, it is not necessary to subsequently dismantle the windows (from the inside and outside).
But if no one took care of the thermal insulation during installation, then you will have to do this very much. Therefore, today we will talk how to warm the double-glazed windows.
Any plastic window includes the following structural elements.
What is characteristic if a breakdown will occur with one of these elements, the window will blow.
For thermal insulation of modern double-glazed windows, it is preferable to apply the same modern materials. In this case, the insulation for the window structure may be postponed one of the following options:
Choosing one or another of them, it is necessary to pay attention not only to the properties of each of the materials, but also on the features of the installation and further use (external and internal). The most convenient option is, of course, the mounting foam, but under the influence of ultraviolet rays, temperature differences or even air it is easily destroyed. Therefore, external work is desirable to perform with the use of "warm" mixtures. And for waterproofing a solution for plaster, you can apply both staining and primer with moisture protection properties.
Note! The only disadvantage in this case is that it is difficult to choose a consumable insulation material, for the installation of which it would not be necessary to dismantle the slopes and other components. Only in such conditions can accurately determine what material should be and how much it will be necessary.
For sealing small slots in places where the window profile adjoins the windowsill and other elements, the sealant can be used. Even the usual household will cope with such work - you just need to follow the instructions for the use specified on the package.
The thermal insulation of double-glazed windows consists, as noted above, it is in the slopes. If we talk about other structural elements, then only troubleshooting will be required. For example, due to the profile, drafts never appear. And the modern technological plastic, which is used in the windows, it is no longer wood, it is unable to "move" or disappear.
Plastic windows lose thermal energy if certain parts of the structure are deployed. And if you do not want to penetrate the cold inside the room, then take care of the isolation of slopes, or do it search for the cause of problems. As, we proceed directly to how to warm the double glazing, but begin with the insulation of slopes of window structures.
7 ways to insulate windows for the winter
Earlier we gave several instructions on how and the best way to insulate the windows for the winter, in addition to this article we advise you to get acquainted with this information.
As you know, in metal-plastic windows, the slopes must be plastic. As a cladding should be plastic, and necessarily hard. What is it caused? The fact is that this material Ideal for additional thermal insulation.
And here the opening formed between window Rama and the surface of the wall, it is necessary to blend with the help of a mounting foam. Of course, there are other options - for example, insulating plates (they are produced from basalt fiber) or foamed insulation. Therefore, you can choose the material that is ideal for current purposes.
Both from the inside and outside the wall should be isolated. But in this case, the materials used will not only be warming up, but also to protect. The insulator itself is necessary to protect against all sorts of external negative factors.
As you know, in some cases, even plastic window structures can be satisfied. And with this, alas, nothing can be done. As a rule, from such a problem "suffer" mainly at home, which are built quite recently. And because of the shrinkage, respectively, the sash are slightly reversed, which has a negative effect on the thermal insulation characteristics of the structure. But this problem can be solved - for this you need to debug fittings.
Conditions of sash can be adjusted by the personnel with special eccentric. When the handle turns, they move for "Calling Square". Establish such elements is necessary throughout the perimeter of the frame. And to ensure the maximum dense clips, eccentric must be scrolled strictly clockwise.
Each of those mentioned above elements there is a special "drawing". If it is directed towards the street, it means that the clamp is weakened. But if this pointer is directed to the seal made of rubber, the window sash is perfectly pressed against the frame design.
Loop B. metal plastic windowslabor structures also have their own mechanism that is responsible for pressing. The device is adjusted using a special hexagon. It is followed here with one simple rule: if the tongue is greatly nominated, then the window flaps are tightly adjacent. To push this tongue, you need to scroll through the hexagon, heading against the clockwise. In case the loop in the window are located on the right, the hex manner is necessary to rotate reverse side. That is, here it is clockwise. It turns out that there is nothing difficult in this event - the elimination of the skew is performed easily and simply.
Note! If the manipulation described above did not bring any result, and the cold air will penetrate into the apartment, then, most likely, problems are more serious. It remains here only to seek help from specialists.
We continue to talk about how to warm the double-glazed windows. Now find out how the preparation of windows by winter is being done.
What is the seal made of rubber? The main function is to ensure the maximum dense fit of the window frame and sash. So that it was more reliable, it is made of rubber, so it does not miss the cold air even if it is closed.
Given that proper care and periodic processing with special mixtures The sealer will serve for quite a long time. But only some of the glass owners do it, because this element is almost all the time behind the flaps. What is already there, only some know that the seal should be periodically to handle something.
For this reason, after five years, the density of the element is leaking. When the sealant comes to unsuitability, it must be changed. For this window, the windows are removed from the sash, then the stroke is removed and the sealing material itself is removed. Replacing the latter nothing difficult: the old seal is removed, and the new one is placed by the groove. If desired, the element can be fixed using glue. It is not necessary about the difference in colors in colors - the element can be both gray and black, but there are no special differences between them.
Note! Limit caution should be shown when removing and installing the stroke. The fact is that he is extremely fragile, so it is pretty easy to break it. And if the stroke break, then the design is no longer installed.
It is worth noting that there are other ways to protect your housing from the cold. We will get acquainted with some of them.
A non-standard method of thermal insulation of the window structure, but quite effective. Ordinary blinds must be wrapped with woolen cloth strips, because of which they will prevent the penetration of the cold into the room.
Through the junctions between the elements of the window sill, the cold air can also penetrate. Therefore, these joints should be carefully close. In addition, in the case of illiterate installation, "black holes" can occur under the windowsill themselves, and therefore the element must be dismantled, and the gaps between the block and stove are carefully processing.
To this end, the plugs open, the windowsill is unscrewed with a screwdriver, and there you will find all the slots (if any), transmitting cold air.
The glass can be insulated with the use of heat-saving film - cheap, but at the same time effective material. It must be glued in such a way that there are no air bubbles under it, because not only the aesthetic indicators of the entire design will depend on this, but also thermal insulation properties.
And if you decide to use such a film, it is better to take care of it to go even before the installation of the glass accessories themselves. Although, in principle, this can be done upon completion of the installation.
This may sound ridiculous, but in another way of how to warm the double-glazed windows can be curtains. These elements perform the feature of the air barrier, which means that it does not miss it in winter (if it penetrates through the window designs). Moreover, the air that passed through the curtains is slightly heated.
Thanks to the correct activities aimed at thermal insulation of window glass windows, will allow to get rid of all errors that were allowed at the stage of installation work. If you want, you can even make some constructive changes in the windows - for example, install the window, replace the sash that opens, on the deaf or vice versa, make adjustments to functionality, so on. And where does the thermal insulation procedure be started? First of all, with the choice of one or another technology, consumables, with the study of a detailed plan further workAnd so that all this is done correctly, it is necessary to objectively assess the overall condition of the window system.
Note! Despite the fact that work on thermal insulation of plastic windows can be performed almost at any time of the year, it would be correct to do this in the warm period. In addition, there is another important condition - the weather should be dry and windless.
But, by the way, in the frost it is extremely easy to detect where the slots are located through which the cold penetrates inside the room. Now consider which "weak points" are available in all without exception of metal-plastic structures. These places include:
In addition, it is mandatory to pay attention to what the windowsill width. The fact is that it should not cover the heating radiators that are under it. Yes, of course, the wide window sill is extremely convenient, but from a technical point of view it is not entirely correct.
There are a number of defects, the correction of which is preferable to entrust to those skilled in the art. These defects relate directly to the design of metal plastic and include the following.
The first point: it will take insulation of sings and slopes of plastic windows outside to do, and it is, of course, not so simple, especially if we are talking about the apartment above the second floor. Second: Power 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 moment: When performing repair work, professionals will use native fittings and window materials.
But if house master It has sufficient experience and knowledge, he will only need quality instructions on how to warm the double-glazed windows in order to choose the most appropriate technology for specific conditions. As for the thermal insulation of the window frame contour, then with this procedure it is possible to cope with your own hands. Moreover, it is possible to isolate theft, slopes and a windowsill. Today we will find out how to do it, but for starters, let's take care of all the materials necessary for work.
As a result, I would like to emphasize your attention on another simple thing: if due to the glass package is lost thermal energySo one of constructive elements Systems failed. And if you eliminate the problem, the window will "get lost again" with previously lost characteristics.
In fact, as already noted above, the insulation of window structures should be engaged in the installation phase. Of course, in this case, the total cost of each window will increase significantly (approximately a third), since the price of thermal insulation material and work will be added to it (if they are not carried out with their own hands). But the operational period of the entire design will be extended. Moreover, it is not necessary to subsequently dismantle the windows (from the inside and outside).
As for the full thermal insulation, it is necessary only for slopes and maybe the windowsill. No other events for the isolation of the window in this case are not needed. Double-glazed windows and so can boast high-quality protection from the cold, since initially calculated to ensure a comfortable microclimate in the room.
Defining factor for the replacement of old wooden windows On new, metal-plastic or PVC, is their ability to keep heat in a house or apartment. Naturally, when installing double-glazed windows, few people were interested in how they would behave in the future. Will the cold be skipping, is it possible to insulate the plastic windows if necessary and should it be done? If so, how to prepare windows by winter and the better to ensure the thermal insulation of windows and openings.
Plastic or metalplastic window, like any composite design, has weaknesses. They are the potentially possible "gates" for heat leakage from the room.
To understand why the PVC window is blowing, you need to see the nodes, and for this you need to know the constructive principle of the window block device.
The presence of a defect in one of the components of the window block leads to the fact that with plastic windows blows. To determine the exact location of the heat loss of metal-plastic windows can be three ways:
Clear business, eliminate the source of drafts. From a practical point of view there are two simple options - Call the wizard for repairing (expensive) windows or make your own hands (cheap).
The desire to close all the gaps on their own by hand-made means is reduced to no, because: first, not aesthetic, secondly, no guarantees.
However, often the cost of attracting specialists equals the cost of installing a new window, and this fact makes it more profitable to carry out work on insulation with your own hands.
Repair and insulation need to be engaged before the onset of cold weather. This is due to such requirements as:
The selection of the insulation depends on the place of puff.
To insulate the opening of the windows, you can use different materials and methods:
Note. The hard insulation is used in the thickness of the mounting seam no more than 3 mm, in other cases it is better to give preference to the Minvat.
Council. It is not recommended to use the usual greasy or window tape, after sticking it on the plastic of the window frame, low-apparent traces remain, which are difficult to remove without damage to the facial coating.
After the question is resolved than insulation, we will deal with the question of how to insulate the glass, frame, plastic, aluminum profile, etc.
Outdoor wind insulation is performed in the following areas:
The first step towards improving the thermal insulation properties of the window. Whatever insulation measures have been taken in the house until there are slopes from the street, the cold will still come inside. In this case, outdoor insulation makes it possible to shift the dew point, which will prevent the appearance of dampness and the development of fungus. The magazine of the slots is a temporary measure, because Over time, the layer of plaster will begin cracking and revealed mounting foamwhich under the influence of atmospheric phenomena collapses. But as protection for insulation, plaster is an excellent solution.
Procedure for performing work:
Council. When installing the insulation, you need to monitor that it overlaps the part of the window frame and completely closed the mounting seam.
To insulate fits enough to fit all the slots or put in them the heat-insulating material. To avoid water from entering the heat insulation material, a metal plank is installed on top of it. The bar is installed at an angle (at least 5 o), its horizontal edge comes out of the facade (by 20-30 mm), and the side edges wrap up. The place of adjoining the plank to the surfaces is recommended to be treated with sealant.
Warming of windows from the inside of the room is carried out in the following directions:
Internal slopes are less susceptible to the influence of external factors, but put forward more requirements for the aesthetic component. Therefore, it is important to know how to insulate the slopes of plastic windows without losing the attraction of the window.
Order of work:
The slots between the wall and the windowsill are one of the places of substantial heat loss. Before deciding how to insulate the windowsill of the plastic window, it is necessary to determine its weak point, i.e. Where does it blow? For example, purging is possible between the plastic parts of the window and the windowsill. In this case, it is recommended to use sealant.
Also possible heat loss between the windowsill and the wall. In this case, the insulation is performed until the windowsill installation by laying the layer of thermal insulation material. And also after its installation - by faving the distance between the windowsill and concrete wall or brick masonry.
To reduce heat loss, you need to adjust the accessories (components) of the window block.
The elimination of plastic windows is possible by replacing the rubber seal. You can change the sealer with your own hands, everything is simple there - it is enough to pull the old seal and insert a new one into the groove (groove).
What sealant is better? Please note on the market there are window insulation black and gray colors. Black seal more plastic, but, attractive light color, caused by various additives that reduce the cost of the seal for windows, and at the same time, worsen its properties (tightness of pressure).
Winding winds often negatively affects ventilation indoors. Full tightness is protection from the cold, but it is a fogging of glasses, which leads to the destruction of slopes and the appearance of fungus. The problem is solved by periodic air ventilation, micro-taking, installation of forced ventilation, etc.
The appearance of drafts in the house is always unpleasant, especially if such a problem appears in the cold season. Replacing old windows to new - perfect solutionIf your windows do not provide sufficient heat and noise insulation and deliver a lot of trouble. Modern windows from high-quality materials installed in compliance with all installation standards do not require additional insulation.
The reason for such defects is poor-quality material from which the product is made.
A temporary solution in this situation will be the stuffing of damaged elements by polymer glue, but the long service life of the window is possible only after replacing the damaged profile or glass package.
Often there is due to the large weight of the sash or errors when installing. Also, this problem appears on frequently used windows.
Usually such a problem is solved by adjusting the accessories.
The reason may be the incorrect installation of sealing rubber, lack of care for the seal or the expiration of its term.
Replacing rubber and adjusting accessories in this case will make the warmer window.
The reasons are two: either it is cheap, or it is incorrectly used.
In the first case it is worth replacing it, in the second - it is enough to adjust. The insulation of old windows is recommended to start with the replacement of accessories.
Plastic windows include very reliable products, but they do not always fully protect you and your accommodation from unfavorable weather conditions. There are many reasons for this. One of them is the wear of some elements of the window, for example, sealing rubber. The seal requires constant care and regular replacement at least once every 5 years. To avoid savings, you need to regularly configure accessories.
In the main aspects, insulation of plastic, aluminum and wooden windows is similar. However, it is necessary to remember that aluminum is a bad heat insulator. Therefore, aluminum windows are not recommended for residential premises.
Aluminum systems are used for facade glazing of buildings, including residential. Solve the problem with thermal insulation in this case will help the installation of the second glazing circuit or replacement of flaps on plastic or wooden.
There are windows intended for cold glazing (Provedal). Such constructions are mainly used for glazing balconies, loggias, terraces and veranda. Their insulation will not bring tangible benefit.
If you value with your old windows, but you are not satisfied with regular drafts, we recommend paying attention to the insulation of windows by swedish technology. In fact, such technology implies a full-fledged wind reconstruction.
First, checks on the correct operation of the sash. If problems are revealed at this stage, then further resort to adjustment or replacement of accessories. Next, remove all the flaps and moving elements. A paintwork is cleaned with frames and sash, eliminate all wood defects and then color. At their perimeter, seals are fixed. The final stage is the installation of elements of fittings and sash.
All problems with old windows can be solved by ordering new ones. At the same time, it is necessary to carefully consider both the choice of configuration of products and the choice of the installation of the installation. The following scheme will help you choose new windows:
The cost of insulation of windows in Moscow varies within different limits. For example, replacing a glass package or restoration of windows in Swedish technology will cost much more expensive than adjusting the accessories or replacing the sealing rubber.
As winter is approaching, and the weather becomes colder, you notice a draft, walking around the apartment. Having placed her hand near the window in a windy night, you find a source of painful coolness. Stop it to endure and sleep under three blankets! There are many ways to insulate the windows. They range from simple to complex, from almost free to pretty expensive, from the "grandfathers" methods to modern technologies. In this Longrid, we tried to collect the most effective methods.
Before making decisive actions, let's consider possible reasons A draft emanating from the windows. It would seem that wooden windows at the expense of their material retain more heat, and plastic - relatively new achievement of science and technology - are simply intended for heat and sound insulation. Then why can they miss drafts to our house?
It is reasonable to start with the diagnosis of the situation. Determine the most critical places from which the wind blows. Where does the cold come from: from the windowsill or window sash? Maybe the problem in the wear seal or poor-quality slopes?
To determine the exact place from which the cold air is blowing, you can simply spend your hand over the surface of the window block. If this way to identify the problem fails, burn the candle or lighter and take them around the frame - the fire is more sensitive to the draft.
Look at the windows when it rains. Moisture accumulated in a certain place will indicate the gaps and cracks. When the humidity accumulates in the corner of the window or along one of its edges, the problem probably lies in the joints. Moisture that accumulates in the middle of the window panel may indicate some type of crack in the glass.
Perhaps the wind blows due to the poor-quality seal. Try to put the paper sheet in the open window and completely close the window. If the paper is easily drawn, barely pulled the sheet of sheet, it means that the sealant is poorly pressed against the frame.
Before you choose a method of insulation from affordable, it is worth thinking on the objectives of insulation. It is clear that temperature regulation is the main task, but what kind of compromises are you ready to go? Will you be able to refuse to refuse cheap beautiful view, limit the influx of light or block access to the window?
It is also necessary to take into account the cost. Some materials are almost worth it: let's say, the sealant can be bought for a couple of hundred rubles. More reliable and durable decisions will be more expensive and may require a specialist help, but in the future there may be worthy investments.
To insulate the windows, you have, in general, only two options: do all the work yourself or contact a professional. It is enough to simply warm the windowsill, the contour frame, the window opening indoors or replace the seal. If some defect manifested itself during the warranty period, the installer will have to eliminate all problems. In addition, it is necessary to resort to the help of installers, if work on outer insulation is required, and the window is located at a considerable height - its replacement or repair work can be associated with an increased risk, and experts know exactly how to warm the plastic windows outside.
It is worth remembering that it is better to warm up the windows before the onset of winter - then the conditions for work will be more comfortable. In addition, sealants and some other building materials can only be used in a certain temperature range, otherwise they lose their properties.
If you need to insulate the window opening, then the mounting foam is suitable. Expanding, it fills emptiness in the opening and prevents air movement. However, foam - short-lived material exposed to low temperaturesand suitable with a small gap. Also, a popular insulation is a mineral wool that has heat and sound insulation. It is stable to high temperatures And convenient in the installation.
Hold insulation window Rams Silicone sealant will also help. It is best when working with it take advantage of an inexpensive tool - a lever syringe. The sealant blocks and moisture, making windows resistant to mold and fungus. It is also worth choosing a transparent sealant - so it will not be noticeable with random hit on the glass.
Before applying sealant or expansion foam, it is worth checking how exactly they expand - to determine this, apply a small drop into the angle of the window.
Another way from the category is "cheap and angry" - shut down the slots in the windows of the technical wool, and then take the painted scotch tape. Previously, tissue or paper strips with a hubber from the household soap were used instead of Scotch. But when using such an option, its briefness is obvious, and he will not be completely out of purge.
A good and inexpensive insulation for plastic windows - Porolaton: Cash costs will be minimal. Remove the film from the glue surface of the insulation and press the foam insulation for windows to the necessary places. With the onset of warming it is very easy to remove. However, when moisture gets, the insulation may lose tightness.
For insulation of slopes of plastic windows, you can use the most different materials - Sandwich panels, plasterboard, foam or expanded polystyrene. However, the foam is the most fragile of the listed materials and has an accumulation of moisture. If you need to warm up the window, you will help dry mixes to finish the slopes.
At first, it is necessary to thoroughly process the gaps - eliminate possible pollution and remove the old mounting foam. If for the insulation of slopes you have chosen drywall, then the sequence of actions is as follows:
Exterior warming work is carried out at temperatures up to +5 ° C, otherwise building materials may lose part of the properties.
You can take advantage of a special heat-saving film for wind insulation. She skips light inside the room and at the same time does not "produce" infrared radiation. Such a film not only protects the warmth of our house, but also helps to get rid of the effect " crying windows", That is, from. Also, the windows on which the heat-saving film is pasted are characterized by greater strength. Before starting work, it is important to wash the glass, to be treated with a degreasing composition and rub dry. Next, it is necessary to stick the film so that its "metal" side looked outside. The film is pasted not only on the glasses themselves, but also with the flax on the frame. Some manufacturers make films on a self-adhesive basis, but for some types of film requires adhesion. To prevent bubbles and folds on the film, use household hair dryer.
Simple and inexpensive Lifehak, which will help cope with a draft, - attach to the window bubble, or "pupil" film. Choose a film with large bubbles, as it is usually better coping with cold air. Cut the bubble film so that it goes slightly on the window frame. Sprinkle with water on the window from the sprayer, then "glue" a sheet of a cut wrapping film on a wet glass. You can strengthen it with bilateral scotch. The "pupil" side must be addressed to the glass. The film should be fixed without difficulty and staying in place for several months. If you wish, you can apply a double layer of film for better thermal insulation. The only minus is such a way blocks the view from the window, but the light will nevertheless fall into the room.
Sewing simple fabric so that it corresponds to the width of the window. Fill it with any bulk dense substance, such as sand, rice or polyester, then place it along the bottom of the window. Heavy materials (jeans fabric, velvet) in this case will keep cold air more efficiently than lightweight materials (cotton, knitwear, etc.).
If the problem is in the worn seal, it can be replaced by it yourself, like a suitable in a construction store. Also, the seal is better to choose black: black color - natural rubber color, and impurities of other colors can spoil the quality of the product. After the old seal is removed, it is necessary to clean the grooves from dust and dirt, treat the corners of the frame with glue and crop over with scissors. The resulting joint also needs to be treated with glue.
People enjoy wooden windows for a very long time, so the question "how to insulate old wooden windows?" There are many answers.
The correct installation of windows traditionally causes a lot of issues from developers. The most narrow places are the "cold" and blowed by the wind of the window adjoining window to the wall and the surges in the winter of slopes, on which mold may appear. You can solve these problems by doing so-called. "Warm" installation of the window, about what we will tell in this article.
Winter plastic windows in winter - a negative phenomenon familiar to many urban residents and owners of private houses.
Condensate dropped on the window.
The second trouble is mold, which appeared on the slopes or the windowsill.
Damp leads to the appearance of fungus at the bottom of the window.
How to avoid this? To answer this question, you need to figure it out in the mechanism of this phenomenon. With a classic heating scheme and natural ventilationThe radiators are taken from below under the window.
The radiator captures the cold air and raises the preheated stream up. Near the cold window, in winter, part of this stream is cooled and go down.
There is a constant mixing of warm and cold air masses in the window zone.
Modern plastic windows, in contrast to old structures, through which the cold dry air from the street constantly penetrated, hermetic. If there is a wide window sill (overlapping radiator), or the radiator is mounted in a niche.
This prevents the natural stirring (exchange) of the air masses and near the window it is formed by the stagnation area.
As a result, blowing the glass is broken. A warm air saturated with water steam comes into contact with a cold double-glazed window, cooled and condensed. This moisture flows down the window. Drips the windowsill, accumulates in the corners, etc.
Over time, this will lead to the appearance of mold and damping finishes.
You can solve the problem like this:
If a single-layer wall is very wide (in cold regions), the window shifts inside by increasing the thickness of a quarter. Thereby decreases the width of the windowsill, the stagnation zone is minimized and blowing the glass is improved.
The distribution schemes of air flow and internal air temperatures in the location zone of PVC profiles at different depths of their installation in the thicker outdoor Wall;
Quarter (from above and from two sides on the sides of the window design) protects the window of the window-wall from blowing the wind.
Also in modern PVC windows The valve for microwave (air inflow, ventilation and additional blowing of the window zone) cold period time.
Described above, only part of the solution to the problem. Often, in addition to the "crying" windows in the house, the slopes are molded.
For example, there is a wall made from aerated concrete. There is no insulation of the facade. Outside the house minus temperature, and indoors - plus. Suppose on the street - 26 ° C, and indoors + 20 ° С. Installed window.
In this design, the window (even high-quality with several cameras and energy-efficient) is a cold bridge. Those. At the installation site of the thermal contour window, the wall is weakened, and the effective thickness of the aerated concrete (which affects the thermal resistance of the entire structure) is actually reduced, and the slope is freezing. It can be clearly imagined:
Temperature fields (isotherms) in a single-layer design.
Isotherm is a line connecting points with the same temperature.
Changing isotherm in the installation site of the window.
Because of this, part of the slope with the window box turns out to be in the zone of the so-called. Dew points. This in turn leads to the condensate in this place.
The problem is exacerbated by the fact that the slope is not closed with vapor-permeable material. Warm water vapor contained in the air of the dwelling, seeks to exit the outside and freely penetrates into the cold slopes, and the conditions for moisture condensation are created in the design. The slopes are moistened and mold and fungus appear on them.
Exit - It is necessary to insulate the slopes with a steamproof material, for example, an EPPS (extruded polystyrene foam) with a thickness of 3-5 cm.
Thus, although the conditions for condensation of moisture in the wall are, but there is no water vapor in a colder zone. The wall remains dry and "healthy" Even at negative temperatures.
The technology of insulation of slopes by extruded expanded polystyrene foam is great for the usual country house. But, to install windows in energy efficient homes, a more advanced option is required. Improve the thermal characteristics of the wall-window node can be used by the so-called system. "Warm" installation.
The main principle of "warm" installation of the window - the entire window structure around the perimeter window Piece It is installed only in the steamproof insulation.
It can be EPPS, PIR-stove, foam glass. Technology "warm" installation windows with facial brick masonry Next, you need:
Scheme: "Warm" window mounting.
Thus, the window is completely cut off from the cold wall.
Now we will stay in more detail on the lower heat insulating part made from EPPS. The nuance in the following - the window should be based and transmit a load on its weight to the reliable rigid base. When installing the window on aerated concrete, brick, concrete, or a wooden jumper in the framework of problems does not occur.
The window is mounted so - under each vertical element of the frame, support pads / wedges are made, made of durable plastic, and not put on, how do some "masters" make wooden sins or trimming from the boards that come to hand.
But extrusion polystyrene foam, although relatively durable material, (it is laid under the foundation, for example, UCH) poorly withstands the local crum. Those. Point load from the support pad.
If you install a window on an EPPS or foam, then these materials can occur with the time under the weight of the window. As a result, the frame can skew, and the double-glazed car will crack.
To set the window on the technology of "warm" installation:
The base scheme from EPPS under the "warm" window mounting.
Thus, tight reference pads under the pads / wedges are formed, which are not sold under the weight of the window.
The height of the EPPS inserts, is chosen in the thickness of thermal insulation. Installation sites inserts - where the support wedges are put. Next, the window is mounted as usual and fixed by mounting / anchor plates to the wall.
"Warm" installation of the window is not a fashionable mesh, but one of the typical nodes of the energy-saving home and a method for reducing the cost of heating and energy expenses.
