Do-it-yourself insulation of plastic windows step by step instructions. Effective ways to insulate windows for the winter with your own hands. Insulation of window openings for the winter

How to keep warm in the house? This topical question is asked by everyone - residents of urban high-rise buildings, the private sector, owners country houses and country cottages. AT winter period the cold strives to penetrate the rooms in any way. Walls, floors, doors and, of course, windows are the main channels through which cold enters the house. But the most vulnerable object is windows. Many are accustomed to solving the issue by installing airtight metal-plastic double-glazed windows. But enough adherents of traditional frames - wooden. With the onset of cold weather, the problem of how to insulate windows for the winter is updated and takes on special significance. High price energy carriers requires active action and bold decisions.

Video tips for choosing materials for thermal insulation of windows

Window insulation: the path of least resistance

Everyone remembers the times when any improvised materials acted as a universal insulation. For the winter, the frames were hammered with what they could - with cloth, rags, cotton wool. At best, they were caulked with foam rubber. From above, they were certainly pasted over with paper strips obtained from internal newspaper fields. Some used plasticine. In a word, everyone knew how to insulate windows.

Particularly advanced putty frames. But the quality of Soviet putties left much to be desired - the material peeled off safely.

Fortunately, today caring homeowners have at their disposal a whole arsenal of tools that easily answer the question: how to insulate windows with your own hands. The most common classic means:

foam rubber;
masking tape;
rubberized seal;
putty;
film.

One of the archaic methods of insulation: fabric or rags are caulked into the slots of the frames

With the help of these materials, it is quite easy to carry out work on insulation. They are also characterized by low cost. However, each method has its drawbacks, among which are the following:

fragility;
the need for dismantling;
foam rubber or adhesive tape will not protect against moisture.

A good option is rubberized insulation. It is a little more expensive, but does not let moisture through, protects well from the wind and is reliable in operation. But it is better to approach the solution of the problem in a comprehensive manner and save yourself from the annual work of tedious work for several years.

Leading group modern materials:

sealant;
silicone seal.

IMPORTANT TO KNOW: Pasting window frames with adhesive tape or paper tapes is fraught with peeling of the material in case of an increase in humidity levels.

Efficient heat preservation: little tricks

So, in order to decide how best to insulate windows, you must first perform a thorough examination of the frames. The main indications for creating a barrier to cold:

the presence of gaps between constituent elements frames;
loose fit of glass and glazing beads to the frames;
errors when installing windows - skewed construction;
insufficiently strong fixing of the block;
chips and cracks in glass.

However, the general diagnosis is cracks formed in one way or another. Most often you have to focus on their elimination.

Rubberized window insulation is an inexpensive and effective method. Service life - one season

The first stage of any construction and repair work is surface preparation. Starting to insulate windows, it is necessary to carry out measures to clean the tree:

wash the frames thoroughly;
wait for complete drying;
degrease with alcohol or gasoline;
let the vapors escape;
clean the surface of peeling paint, small chips.

In the process, it will just become clear how windows can be insulated.

If there are damaged glasses, they must be replaced. It is also recommended to check the suitability of the glazing beads. Over time, they become thinner, split. Another factor affecting the condition of the frames is frequent fluctuations in the level of air humidity: the frames either shrink or expand. This problem is typical for the private sector, especially if miscalculations were made when installing waterproofing.

IMPORTANT TO KNOW: If the air in the house is excessively dry, you can moisten the space by putting open container filled with warm water.

Outdoor work - how to insulate windows from all sides

It is desirable to carry out window insulation in two stages: from the outside and from the inside. As noted above, careless installation of windows with skew or insufficiently reliable fastening often becomes a source of problems. Or the frames are very dry, loosened.

All of these shortcomings can be eliminated. You can't say it's easy. But the result is worth the money and effort spent. The algorithm for performing work is approximately as follows:

examination of frames and side external slopes;
detection of cracks, voids, cracks;
removal of the plaster layer and release of the frame;
removal of crumbling fragments of the solution with which the block is strengthened;
void filling mounting foam;
after the foam has hardened, cut off the excess;
plaster.

if necessary, replacement of glazing beads;
filling cracks, gaps;
grinding;
staining.

IMPORTANT TO KNOW: Poorly protected windows are the main cause of heat loss (up to 50%).

Sealed from the inside: maximum sealing for insulation

Sealant is one of the effective answers to the question of how to properly insulate windows. This material, due to its penetrating and binding properties, connects adjacent surfaces almost perfectly. Careful sealant treatment of each frame joint - the basis reliable protection windows. However, we must not forget that such a procedure requires certain skills. It's best to do it this way:

using a flat paint brush completely clean the previously prepared surface from the smallest specks;
use to apply sealant construction pistol;
make sure that the material lays down in an even layer;
avoid interruptions in the squeezed out "sausage";
be sure to let the sealant dry completely before cutting off the excess.

Do-it-yourself window insulation will give effective result. The service life will be 15-20 years. The subtlety and laboriousness of work is more than offset by durability. However, sealing in this way cannot be carried out when frost is on the way. The temperature of work performance is from +5 °С to +40 °С. That is, in frost you can only work with internal frames.

IMPORTANT TO KNOW: It is recommended to use gasoline to remove sealant from glass - it will dissolve the material and leave no residue.

There is a similar method that has also gained popularity - the use of a silicone rubber seal. It is distinguished by a tubular profile and the possibility of choosing a material of a suitable diameter - depending on the size of the slots. Insulation of windows for the winter performed in this way is considered effective, but requires certain skills.

Another important factor- tightness of glazing beads. Most often they are nailed with small carnations. But this element is perfectly fastened with a sealant. As in the case of external insulation, window painting or varnishing plays an important role.

The silicone rubber seal must be carefully pressed against the surface to be insulated at the junction of the frame parts.

Traditional methods: features of materials

If you carefully protect the windows with modern techniques, pasting and other traditional techniques are losing their relevance. However, not everyone has the opportunity to overhaul windows. Also, if the frames are reliable enough, the tape for window insulation is quite effective remedy.

For many years, foam rubber has not lost its position. This material can caulk all the cracks. Adhesive-based strips are easy to mount to the surface and provide a good seal.

But there are also obvious disadvantages. The main one is a spongy structure, which entails the absorption of moisture and freezing during the onset of severe frosts. At the same time, the main function is lost - the foam rubber for window insulation ceases to protect against exposure to cold air, and the cold sneaks into the house.

To stick the film on the window, you should use double-sided tape

Another "old-fashioned" method, which, however, can be given modern features, is a window insulation film. Previously, dense polyethylene was mounted with outside frames, which significantly reduced the level of illumination of the premises. Modern films are thin, transparent and easy to install: they are simply glued to the glass from the inside using double-sided tape. But you need to be prepared for the fact that with high humidity adhesive tape may fall behind.

However, experts will help to protect housing from the cold really effectively. Professionals thoroughly understand the intricacies of painstaking work that requires high precision and smart approach. They will also select suitable materials for window insulation and carry out the practical implementation of advice and recommendations.

Per last years popularity plastic windows has increased significantly. In spite of this wooden windows are still quite common. Therefore, the question of how to insulate wooden windows for the winter remains relevant to this day.
In winter, up to fifty percent of heat is lost through old windows. There are 7 ways to insulate windows for the winter.

Heat transfer mechanisms

There are three main mechanisms for heat transfer:

direct heat transfer (heat conduction) through windows, walls, doors, ceiling and floor;
infrared radiation through;
convection - heat escapes through porous materials, cracks and cracks.

Traditional ways of warming

If the budget is limited, then we often insulate wooden windows for the winter with improvised materials. Short review budget ways insulation:

If the windows do not close tightly, then use self-adhesive rubber seals of suitable thickness. You can buy them in any hardware store. There are times when the glue does not stick well. In this case, use a hair dryer or fan heater.
Toilet paper is soaked in water, squeezed and stuffed into the cracks. Glued on top
With the help of cotton wool, foam rubber or tow, the joints between the frames and sashes are clogged, after which they are sealed with adhesive tape.
Relatively cheap but reliable material- self-adhesive foam rubber, or polyethylene foam. It simultaneously possesses the properties of insulation and adhesive tape. Sold in rolls like tape.
The cracks are covered with plasticine or ordinary window putty. But the method has a big minus - it is difficult to remove them from the window in the spring. This method is used only in extreme cases.

Use of heat-saving film

One way to insulate wooden windows for the winter is to use heat-saving film. If in winter condensation and frost appear on the inside of the window glass, this is a sign of low thermal insulation properties. The problem is inherent even in modern double-glazed windows. The film is installed on inside frame, parallel to the glass.

It simultaneously performs two actions: it prevents the loss of heat in the form of infrared radiation and creates a heat-insulating layer of air between the film and glass. It makes it possible to avoid the effect of "weeping windows".

Thermal film installation is quick and easy. First of all, the frame is cleaned and degreased, and glued around the glass. The usual film is sold folded in two layers (the layers are separated before use).

The film is glued to the adhesive tape so that it covers all the glass. It is pulled on, not paying attention to the wrinkles that have formed. When doing this, make sure that the edges of the film are securely seated and no bubbles form. After that, the hot air of their hair dryer is blown onto the film. Under its influence, it stretches and smoothes.

Window insulation with paper and soap

This method is one of the oldest and is rarely used. Paper from newspapers is torn into pieces, moistened in water and all the cracks between the frames are sealed with the resulting mass. Before insulating wooden windows for the winter with your own hands, you should prepare necessary tools: knife, flathead screwdriver or metal ruler. When all the cracks are sealed, strips of paper and adhesive tape are glued over them. You can also use fabric. Strips of paper must first be lubricated with moistened soap, which will allow them to be securely attached to the surface. The method is relatively cheap, but has one serious drawback - it is problematic to remove the paper without damaging it. Windows often have to be repainted.

Window insulation with foam rubber

This type of insulation is similar to the first. The difference is only in the material used, that is, foam rubber is taken instead of paper. You need to familiarize yourself with the installation technology before insulating wooden windows for the winter. Expert advice is not at all obligatory, since the technique is quite simple, and any errors are easily eliminated.

Foam rubber strips are sold at any hardware store. Compared to paper, their dismantling is simple. On top of them, you can also stick strips of paper, pre-lubricated with soap.

Foam insulation

The best advice on how to insulate windows for the winter, of course, will be given by experts. Using mounting foam is one of the most effective ways. In recent years, it has become widely used in construction work, as well as in everyday life. blow out all cracks, chips and other defects. After the cavity is filled with foam, it is allowed to dry. The excess is cut off with a regular knife.

When foam is applied outside, all places in without fail plastered. This must be done because the foam crumbles in the sun and turns into dust. In general, the material is reliable and durable.

How to insulate windows for the winter: instructions and step-by-step technology

The silicone-based method requires more effort than conventional gap filling, but it is also the most effective. This is due to the fact that the method allows not only to minimize heat loss and improve the overall sound insulation of windows.

The technology is as follows: glass attachment points are insulated with silicone. First of all, the frames are removed from the hinges and placed on the floor, after which the glazing beads are dismantled. You will need a flathead screwdriver for this, but a knife will do. It is important to be extremely careful, as the glazing beads can break. It is advisable to buy spare parts in advance. After their dismantling, the glass is removed. All work should be carried out with gloves, as there is a high probability of cutting yourself.

The place where the glass was previously located is cleaned of all kinds of contaminants and filled with sealant. On next step the glass is put back, after which they pass the sealant a second time and clog the glazing beads back. At the end of the work, the frame is hung back. In parallel with the insulation, it is recommended to repair the frame: remove old paint, fill cracks, put high-quality constipation. In the question of how to insulate wooden windows for the winter, every little thing plays an important role.

Tip: It's best to use clear sealant as it won't be visible if it gets on the glass.

Elimination of cracks

Under the influence of different temperatures wooden frames often crack. Before insulating wooden windows for the winter, all these cracks should be sealed.

For this, the following materials are used:

melted paraffin;
sealant;
a mixture of sand and flour in a ratio of one to three.

There are other methods, but they are less common. When using any of them, the windows will have to be repainted.

Insulation of windows along the perimeter of the frames

In the general case, window insulation is the sealing of cracks where the window sashes adjoin the window frame. The tightness of the joints can be achieved with the help of rubber tubes with an adhesive base, foam rubber tubes, polyurethane foam and other materials.

One of the most effective ways to place a sealant is to stick it to the window transom along its entire perimeter. When the window is closed, the seal will bend and block the cold air flow from the street. At the same time, it is important to ensure that the frame bends the seal, and does not slide on it.

If the frame is wide enough, then the sealant is glued in several rows. To make it securely fastened, it is nailed along the edges with small nails. This will prevent the material from peeling off. It is important to carefully inspect the frame before insulating windows for the winter. Insulating wooden windows with a sealant can cause them not to close. Therefore, the frame sometimes needs to be hemmed so that the seal does not move the sash forward, as a result of which the window does not rest against the adjacent sash.

This method is most effective when used in conjunction with window seating with silicone sealant. One of the main advantages of the method is that with the departure of winter it is not necessary to dismantle the entire seal, so it can be used for several years.

Finally

Wooden and plastic windows have their advantages and disadvantages. They are distinguished by their soundproof and thermal insulation characteristics and require completely different care. In our climatic conditions, the issue of window insulation still does not lose its relevance, therefore, it requires careful and in-depth consideration.

Having studied the mechanisms of heat transfer from the apartment to the outside, as well as the design features of the building, it is possible in the shortest period of time with minimal cost qualitatively and reliably insulate the room. Windows play perhaps the most important role in this. Therefore, they are engaged in warming in the first place. The article described the main options for how this can be done efficiently and professionally. We hope these tips are helpful to you.

A third or even half (depending on the area of glazing) of heat loss in the house falls on the windows, so with the approach of cold weather, you need to take care of thermal insulation. Consider effective and inexpensive ways how to properly insulate old wooden windows for the winter with your own hands.

Despite the widespread replacement of wooden windows with plastic and metal-plastic ones, they retain a part of the market. Despite the fact that from the point of view of heat-saving properties, PVC windows are more preferable, a number of users, according to different reasons, continues to exploit the old wooden windows.

There are several explanations for this fact:

the high cost of plastic windows (which may also require insulation);

environmental friendliness of wooden windows and their ability to maintain an optimal microclimate in the room due to natural ventilation;

there is no desire to make repairs after replacing windows;

distrust of plastic structures;

accommodation in a hostel or rented apartment;

the need to insulate windows at work, in educational institutions etc.

With all the advantages of wooden windows, they do not match modern requirements for energy efficiency and heat saving (except for wooden windows with double-glazed windows). So the owner has to think about how to insulate wooden windows so as not to blow.

Any insulation of old wooden windows provides for blockage (sealing, putty) of all cracks that can potentially be a source of heat loss.

Due to the fact that wooden windows have been in operation for more than one century, and users have always faced a lack of tightness, they have invented a lot of ways to insulate and. After all, heat loss through a window exceeds heat loss through a wall of a similar area, which means it will be right to find out how to insulate wooden windows for the winter.

How to start window insulation

Work begins with finding out the place of blowing. In the case of wooden windows, these include:

slopes (external and internal), incl. beams to strengthen the opening;
ebbs and window sills;
junction of the sash to the window frame;
frame wood;
glass.

How to insulate wooden windows for the winter with your own hands

To begin with, we note that all existing ways insulation can be divided into two directions - external and internal, which means that the technology of warming wooden windows will be considered in two directions.

1. Insulation of wooden windows for the winter outside

External insulation is carried out with outer side windows from the street. It is much easier to perform this type of work in a private house than in a multi-storey one. However, in the apartment and in the house, the following options are available for execution:

Insulation of window slopes from the outside

thermal insulation window slopes a mandatory step, since insulation from the inside does not exclude the possibility of heat loss from the street. As a heater, polyurethane foam or rigid insulation is used.

How to insulate slopes from the street:

inspect the window along the perimeter of the frame, remove all elements that do not adhere well (old putty, mounting foam, insulation, plaster, paint, etc.);

prime the surface of the slopes;

blow out all the cracks with mounting foam and / or stick the foam on the slope. In the process of installing the foam, you need to make sure that the sheet goes on the frame;

if only foam was used, it must be cut off after complete solidification and sealed with plaster. If foam plastic was used, it must be covered with a polymer mesh, a perforated tape should be installed in the corners and the slope should be plastered;

after the plaster has completely dried, the slope is primed and painted.

Note. External insulation works are carried out at temperatures up to +5 °C. At low temperatures foam and adhesive mixtures lose some of their characteristics and properties.

Window flashing insulation

Low tide is the lower part of the slope. Here it is recommended to blow out all the cracks with mounting foam and install a low tide bar on top. It is necessary to provide an opportunity to drain water down (the ebb bar is set at an angle), wrap the side edges up to avoid water leakage, bring the bar 20-30 mm beyond the edge of the masonry, seal all joints of the bar and the slope or frame with sealant.

Elimination of cracks

Do not forget that wood is a breathable and non-hygroscopic material, so the outside of the window needs to be painted or varnished.

Advice. If detachment of the existing paintwork it must be removed with a building hair dryer and a new layer applied.

2. Insulation of wooden windows for the winter from the inside

Consider the main methods internal insulation windows (thermal insulation from the side of the room), which can be conditionally divided into temporary and conditionally permanent. The first group of activities includes those that are performed during the cold season and are cleaned in the spring by washing frames and windows. To the second - those that ensure the tightness of windows for a long period.

How to insulate old windows

paper;
cotton wool;
foam rubber;
rubber or polymer seals;
mounting foam;
acrylic or silicone sealant;
hard or soft insulation;
paraffin, alabaster, etc.

How to insulate wooden windows with paper

This is the first option that comes to mind if you need to quickly and inexpensively insulate old windows. Of course, the aesthetics of the window suffers from this method, but the level of tightness is quite high. The material was prepared for the site www.site

To make paper putty, you need to grind paper (it is better to take old newspapers), soak it in water, wring it out, add 1 part of clay or 2 parts of crushed chalk to the mass, and seal all the cracks with the resulting mass. The putty is plastic and easily clogged even in small cracks. To apply the mass, a knife, screwdriver, metal ruler or other suitable tool is used.

To cover the paper putty, window tape or special paper with adhesive properties (such as masking tape), window tape or fabric strips are usually used. Cloth and paper are smeared with soap dipped in water and glued over the cracks.

The insulation is kept until the onset of heat, and then removed. At the same time, unattractive streaks remain on the window that need to be washed off.

Note. If decorative coating does not hold well on the window, you need to be prepared for the fact that some part of it will be removed along with adhesive tape or paper and painting will be required.

How to insulate wooden windows with wool

The method is similar to the first, but instead of paper putty, cotton wool is used, which is also covered with strips of paper / fabric.

Insulation of windows with a sealant (regular or tubular foam rubber)

Ordinary foam rubber is placed between the frame doors and closed. Foam rubber distinguishes low price and availability. As well as the possibility of reuse next season.

The tubular foam rubber is glued to the sash of the window frame from the inside with adhesive tape. The advantage of this method is the ability to use the window - open / close (for example, ventilate the room). The seal is securely held on the sash and does not interfere with the operation of the window. In addition, it can be glued in several rows, which increases the tightness of the fit of the window sash to the frame.

A good option is a self-adhesive window tape made of rubber, polyurethane or polyethylene foam, made in the form of adhesive-backed tubes.

The choice of sealant depends on the temperature, the quality of the material, the size of the gaps. Learn more about window seals in the video

Insulation of wooden windows using Swedish technology

This is one of the effective ways of insulation using a sealant. The difference lies in the technology of its installation. In this case, before installing the seal, you need to make a groove in the frame and place the seal in it.

As you can see, the Swedish technology is, in fact, a partial restoration of a wooden window. And, in terms of their heat-saving properties, ordinary wooden frames are close to metal-plastic ones.

Why insulate plastic windows? This reasonable question arises, for sure, among all owners of modern hermetic structures, because manufacturers sold us a perfect product with perfect thermal insulation. Installation errors, improper operation, house shrinkage and time can play a cruel joke even with the highest quality windows. Do not rush to change the entire structure - you can try to insulate plastic windows with your own hands. It's easy and short. Dealing with weak points modern windows and learn how to fix them.

No. 1. Why plastic windows need insulation?

Qualitatively made and installed plastic windows for the first years will certainly reliable barrier cold air, drafts and noise. Over the years, of course, problems can appear, and often the user himself is to blame. With dishonest installation, various defects can make themselves felt in the first season.

The most common reasons for additional thermal insulation of plastic windows:

installation performed in violation of technology;
shrinkage of the building, which is especially typical for;
wear of rubber insulation. Responsible manufacturers and installers inform the user about the rules for caring for a rubber seal, but few people follow the rules and regularly inspect the condition of this structural element. Lack of proper care leads to an accelerated process of rubber thinning and drying, the appearance of microcracks in its structure, the result is a decrease in the fit to the frame and deterioration of thermal insulation;
incorrectly installed slopes.

Window of poor quality or with inappropriate climatic conditions technical characteristics will also not be able to provide normal thermal insulation, therefore it is so important to be able to correctly and immediately determine the appropriate one.

No. 2. We identify weaknesses

To spend effective insulation plastic windows, you must first figure out in which places the tightness is broken. Immediately, only the frame can be deleted from the list of suspects: multi-chamber plastic is a good heat insulator, it does not dry out, unlike.

Cold air can penetrate through such structural elements:

A double-glazed window rarely causes a violation of thermal insulation (an exception is its depressurization), but it can also be additionally insulated. "Extra" heat in winter does not hurt.

Detect leaky items window simple - just run your palm along and across the entire structure, and you will feel that in some places it is blowing decently. Some advise using a lighter for this purpose. If you light a flame and run it around the perimeter of the window, maintaining a safe distance, then it will tilt in those places where there is even a small draft. Be extremely careful with this method!

As a rule, work on the insulation of a plastic window can be done by hand. The exception is when it is necessary to insulate from the outside, and the apartment is located above the second floor. You need to be prepared that complex insulation may be needed if several zones of warm air leaks are found, but first things first.

No. 3. Debugging the clamping mechanism

Shrinkage of the house and weather factors can lead to a slight misalignment of the window sashes and slight deformation. sealing gum. This leads to a deterioration in thermal insulation, but in this case, returning to its former tightness is a matter of a couple of minutes, however, knowledge of the design of the plastic window and skills in working with tools will be needed.

Presser adjustment can be carried out with the help of special eccentrics located along the perimeter of the wings. To make the sash fit tighter, the eccentric must be turned clockwise using a 4 mm hex wrench. Focus on the serif located on each such element. When it is directed towards the street, the clamp is loosened, towards the seal it is strengthened. Everything is well shown in the video.

Sometimes a simple window helps to insulate a plastic window. loop regulation, which also have their own mechanism responsible for the pressure density. Here the regulation is carried out using a hexagon. You should be guided by a simple rule: if the tongue is strongly advanced, then the sash fits well. To pull it out, you need to turn the hexagon counterclockwise if the hinges are on the left, and clockwise if on the right.

Things are even easier with glazing bead. It is enough to pry off the old departed glazing bead with a thin spatula, and install a new one in its place, which can be bought from the same company that sold and installed the windows for you.

After adjustment, check whether the tightness of the structure has improved, with the palm of your hand or with a lighter. If everything is done correctly, and the draft is still walking, then you will most likely have to change the seal.

No. 4. Seal replacement

Perfectly rubber compressor can last a long time, but for this it is necessary to comply with certain conditions. According to the rules for the operation of plastic windows, the seal must be regularly lubricated with special substances, but which of us does this? So it turns out that after 5 years the rubber dries out and begins to let in a cold breeze from the street. The problem may be in the seal, which is located under the glass, or in what is located along the contour of the sash. Replacing the seal in a plastic window is not as difficult as it is responsible. If you doubt your skills, it is better to call a specialist.

Procedure for replacing the glass seal:

May need to be replaced sealant, which is located along the contour of the sash. In this case, it is better to remove the sash. First, the decorative trims are dismantled from the hinges, and then with the help of the mounting handle or the pin is pulled out of the hinge. It remains to carefully remove the sash, and only then it is very easy to remove the old seal from it. It is better to start installing a new seal from the top of the sash, gently pressing it, but not stretching it. It is better to fix the beginning and end of the sealing tape with glue. Everybody! It remains only to hang the sash back: the pin can be installed with bare hands, and then the decorative trim can be returned to its place. The video is very well shown and described.

No. 5. window sill insulation

The installation of a plastic window is often associated with decent destruction, they are especially significant in the area between the wall and. Some installers fill the gaps with cement and construction waste. There are no comments here. It is better, of course, when the space under the windowsill is flooded, but this option is not ideal either. Foam can shrink or even dry out over time, decent gaps are formed through which cold air enters the house.

To insulate a plastic window, you will have to get rid of the old foam and fill in a new one. Keep in mind that it tends to expand when solidified. After complete solidification, the excess is cut off; some builders recommend additionally filling small cracks with silicone sealant. After that follow plastering work and decorative coating.

If possible, the window sill area can be additionally insulated from the outside. For this, mounting foam is also used, but sometimes it is also used. From above, everything is on the grid and gets off.

No. 6. Slope insulation

Today, often when installing plastic windows, slopes are additionally installed, even, beautiful, made of dense plastic. It often happens that there is a large crack between the decorative strip and the wall, which perfectly conducts cold and wind into the apartment, therefore, to improve the thermal insulation of plastic windows, it is recommended to insulate the slopes from the inside or outside.

The procedure is as follows:

dismantling of unnecessary parts of the mounting foam;
if the surface is very uneven, you can plaster it;
slope treatment with a primer, antibacterial compounds can be used to prevent the development of mold;
a fragment corresponding to the slope is cut out of the foam plastic. To better adhere to the surface, with reverse side it can be slightly scratched. It remains to apply mounting adhesive and press firmly against the surface of the slope; for a guarantee, several dowels can be installed;
it remains to mount the corner, putty the surface and fix the trim.

No. 7. What else can be done to insulate a plastic window?

The above methods will allow you to reliably insulate plastic windows and get rid of all the cracks, but it is possible to make the structure even warmer - it will not only not let the cold into the apartment, but will also prevent warm air from leaving the apartment. This is not magic, but reality, which is achieved through the use of:

heat-saving film;
window heating;
woolen blinds and curtains.

Heat-saving film- a thin transparent material that does not change the optical properties of glass, but reflects thermal energy back to the apartment. The effect is achieved due to the presence of a thin metal layer. Of course, when it comes to plastic windows, it is better to use a special heat-saving double-glazed window - its efficiency is many times higher than any film, but if a regular double-glazed window is installed in existing windows, then additional insulation will not be superfluous.

You can easily handle the installation of the film with your own hands:

the surface of the glass and frame are thoroughly cleaned;
double-sided tape is glued around the perimeter of the box;
the necessary fragment is cut off from the film roll, it is better to cut with a margin;
the film is glued to the previously attached double-sided tape, its surface is blown warm air from a hair dryer. It is necessary to act slowly so that the result is neat, there are no distortions and bubbles. A properly glued film is almost invisible.

Glass heating it is already more difficult to equip, it is better to do this at the stage of window installation, but most window companies can install such a system already at installed window. Heating is carried out at the expense of the electric heating spiral which is built in glass.

And finally, the most banal, simple and universal ways make the window a little warmer. it thick curtains and woolen blinds. The latter can be done by wrapping ordinary blinds with a woolen cloth.

It is better to carry out work on the insulation of plastic windows on a warm, dry day, since it is no longer possible to work with many materials at temperatures below +5 ... +10 0 С, and you can let the cold into the apartment. In order to face the problem of warming as late as possible modern window, it is worth taking the choice of a window manufacturer as seriously as possible, paying attention to the selection of optimal specifications depending on the climate of the region. It is also important to choose a responsible installer and remember to properly maintain the window.

It often happens that colds come unexpectedly and sunny days are replaced by chilly winds and rains. Therefore, you should take care of the weather in the house in advance and you need to start with the windows. If you make the right choice when deciding how to seal windows for the winter, you can keep up to 2/3 of the heat in the room.

Contrary to popular belief that only wooden windows need to be insulated with one's own hands, plastic structures also often need to improve their heat-saving qualities. This happens if the life of plastic windows has ended or the structures were installed in violation of the technology.

To insulate windows for the winter with your own hands, you need to create the most airtight space between the frames, since the air in the closed space has excellent heat-insulating properties.

To obtain comfortable temperature in the room, you need to eliminate the gaps through which cold air enters.

To insulate wooden frames, one (or both) of traditional ways: gluing sealing gum, sealing gaps with cotton wool, glue and paper strips, fabric or tape. An adsorbent can be placed between the frames - a substance that absorbs moisture, for example, Activated carbon, silica gel, soda or salt.

Preliminary preparation of wooden windows

Before starting work, wash and wipe the windows, inspect the gaps between the frames and glass. Such gaps appear when the frames dry out, and the window putty in which the glass is installed crumbles.

Repair stages

Check the condition of the glazing beads - long wooden slats, with the help of which glass is strengthened in the window frame. It is better to immediately replace rotten and cracked elements with new ones.
Pull out problematic glazing beads and nails. Take the glass out and clean it of putty residue with alkaline products, such as soda ash diluted in water.
Clean the frames from putty and paint in places where the glass is inserted, wipe dry and treat with transparent silicone sealant.
When installing glass, try not to pinch it. Secure the glazing beads with window nails.
Coat the remaining gaps with the same sealant, let it dry for 2-4 hours and wipe the windows with a special detergent.

How to insulate wooden frames

Window structures made of wood are usually insulated with:

Modern profile seal

Window seal profiles

This material is sold at any hardware store and is a tape, with or without an adhesive layer. Such a seal is also called a tubular profile and is made of the following materials:

foam rubber
rubber
polyvinyl chloride;
polyethylene foam;
polyurethane

Adhesive-based seals are more popular. But their disadvantage can be considered that they cannot stick as securely as their self-adhesive counterparts.

The foam rubber seal absorbs moisture, so it must be replaced annually. The polymer tape is water resistant, which significantly increases its service life.

The sealant is easy to use: the tape is glued on open sash around the perimeter, inside and out. To eliminate especially large gaps, you can additionally use masking tape.

For gluing a sealant without an adhesive base, it is best to use a transparent silicone adhesive-sealant.

improvised means

The method is suitable for insulating old wooden windows for the winter. , as it is designed to eliminate too large gaps . They can be filled with cotton wool, rags, paper or foam rubber. A special putty for wood is also suitable.

Stages of warming:

firmly tamp the cotton wool or other material into the slot using, for example, a wide screwdriver;
glue strips of fabric or paper over the material.

Glue for these purposes can be made from a soap solution or two components - water and starch. The recipe is simple: pour a heaping tablespoon of starch with one 200 ml glass of water, bring to a boil, stirring constantly.

Instead of starch, you can use sifted flour. After cooling the paste, proceed to the insulation.

Paraffin can be purchased at any hardware store.

This method was widespread several decades ago among housewives who knew exactly how to insulate wooden windows for the winter, as they allowed them to big gaps quickly and at no cost.

Melt the paraffin candle in a water bath and pour the hot mixture into a preheated syringe. With this device, you need to quickly process all the gaps.

Putties

Insulating windows for the winter with special mixtures or something similar with your own hands is an effective, but radical method. Removing such insulation often damages the paint, so this way suitable for old windows that you plan to replace soon.

Adhesive putties, a solution of alabaster and chalk 1: 1, special sealants for window seams are suitable as a heater. The mixture is applied to the gaps, leveled with a spatula and left to dry completely.

Heat-saving film is an effective way to avoid heat loss

This method is suitable for warming wooden window structures and PVC windows.

In hardware stores you can find a special protective film, which has universal properties - in the summer it protects the room from sun rays, and in winter it raises the temperature to 5 degrees.

Material the right sizes glued to the frame glazing beads with double-sided adhesive tape and blown with air from a hair dryer to level and make it transparent.

Additional cold bridges

Be sure to check jumpers above the windows, as they often serve as a place for heat leakage. Jumpers are insulated from the outside by alternately applying facade expanded polystyrene, reinforcing mixture and plaster.

Also conductors of cold can be slopes. For thermal insulation, the side surfaces are sanded, then primed and PVC panels are installed. If voids have formed inside, it is necessary to fill them with tow or polyurethane foam.

Windowsill, incorrectly treated with foam, are insulated by attaching a piece of PVC panel under it, adjusted to size. The voids are filled with the same materials as in the case of slopes.

How to insulate plastic windows yourself

To improve the thermal insulation qualities of plastic windows, it is imperative to use a heater. This can be a traditional mounting foam or a sealant suitable for this purpose:

polyurethane sealant. Experts consider this material ideal for sealing deep cracks, since the mass after hardening increases its volume several times and penetrates far deep into the gap.
Silicone sealant. This is the most popular and affordable means of getting rid of unwanted sources of air entering the room. The sealant tightly fills the gaps and has a high elasticity, which makes it easy to use.
acrylic sealant. Differs in elasticity and ease of use - its excess can be easily removed during application, unlike silicone sealant. But given material has one drawback - a short time exploitation acrylic sealant changes color from white to grey. This is due to its ability to attract dust and dirt to itself.

When insulating plastic windows, follow the main steps:

Clean the cracks with a stick or brush from crumbled mounting foam or debris.
Thoroughly go over the slopes, frames and window sill with a degreasing cleaner.
Fill the gaps with mounting foam or sealant, depending on the material chosen.

Summing up

If the budget does not yet allow you to replace old windows with new ones, do not despair. A variety of materials for their insulation will allow you to choose something for yourself based on the financial condition and the characteristics of the work.
