What is the best way to insulate windows in winter? How to insulate plastic windows for the winter with your own hands - we will teach! We reanimate thermal insulation

Despite modern technology, wooden windows remain a popular element of window designs. This is primarily due to their environmental friendliness. However, their significant drawback is their weak thermal insulation properties.

But this problem is completely solvable. By insulating such a structure, you can protect the house from the entry of cold air into winter time year and thus provide warmth and comfort in the house.

What we insulate

Before the onset of cold weather, you should carefully examine the window for the presence of so-called cold bridges, the main ones being:

Window sills. The main heat loss occurs through this zone. There may be several reasons. One of them - the installation of the structure was carried out incorrectly. Perhaps the foaming was carried out poorly. Large gaps can occur in buildings with a fairly long service life.
Lintels above the windows - beams to strengthen the opening. This moment can be revealed only from the outside. Therefore, the insulation is made with outside walls.
Slopes. There may be gaps between the frame and the wall, the appearance of which cannot be avoided even with correct installation windows.
Glass. Thermal infrared radiation penetrates into the room through this element of the window. Therefore, their condition is very important. In addition, it is necessary to check the glass for cracks, chips.

If no visible errors are found, but the cold air coming from the window is still felt, it is quite simple to check exactly where the heat loss occurs.

By running your hand along the entire structure, you can easily feel the flow of cold air. You can use a lit candle - in a place where the flame fluctuates, insulation should be made.

material for insulation

Since ancient times, improvised means available in almost any home have been used to insulate windows:

Tapes made from paper or old newspapers are the most popular way to insulate wooden windows. It is quite effective, but has one drawback. At the end of the cold weather, it is difficult to remove the strips from the frame, and the paint can be damaged.
Strips of fabric and cotton. The slots are clogged with cotton wool and glued on top with fabric strips or special tapes. Heat losses are minimized, and removing them in the spring is quite simple without damaging the coating.
Foam and tape. This method of insulation is identical to the previous one and is used when there are large gaps between the frame and the wall. Foam rubber is glued around the perimeter of the frame. Tape is applied on top. This material is more durable, but, again, peeling off the tape can damage the paint on the frame. In addition, over time, the foam rubber begins to crumble.
Paraffin is used in the presence of small gaps. The advantage over other methods of insulation is that it does not need to be removed in the spring. It will serve well for several years.
Plasticine or window putty. The effect of such insulation is significant. But the problem is the subsequent removal of this material from the surface of the frame.

All of the listed materials do not require any costs or special skills for their use. But they all have almost the same drawbacks - fragility, moisture permeability, the need for dismantling.

Modern materials that act as insulation for windows can get rid of these problems. The main ones among them are:

Sealants silicone, polyurethane, butyl. This material is used most often for a tighter fit of glass to the frame;
are tubular gaskets coated on one side with a self-adhesive compound. They can be made from different material– PVC, polyethylene foam, rubber, polyurethane and foam rubber. But it is impossible to carry out work on warming with this material in winter, this must be done before the onset of cold weather;
The heat-reflecting film perfectly keeps heat in the room in winter time. At correct installation it does not affect visibility through glass in any way.

Besides, in summer period reflects the sun's rays, preventing the room from warming up.

Rules for warming wooden windows

Before insulating windows, it is necessary to inspect the entire structure for cracks, crevices, gaps, etc., and determine their dimensions. The heater is selected according to all these data.
When buying a material, you must carefully read the information on the packaging. It is extremely important to check its expiration date. This is especially true for self-adhesive seals. Material that has expired very quickly will fall off the frame surface. The same goes for sealants.
The sealant must be white color or transparent. As for seals, it is better to choose soft types which, when the pressure is removed, restore their shape.
Before starting work, ventilate the room, at high humidity paste over wooden frames pretty hard.
Next, you need to clean the places that will be directly insulated. This is especially important when working with sealants and sealants. On a dusty surface, the material will not adhere to the wood.
If windows in summer time open, then use fastening materials(mounting foam, silicone sealant, gypsum) at the junction of the valves is not worth it. The same applies to vents. Here you can use improvised home remedies.

Ways of warming with improvised means

At work, you may need:

Thin spatula.
Soft cloth.

Having prepared in this way, you can proceed directly to the warming procedure. It can be produced in different ways:

Using a thin spatula or knife, plug all the cracks with cotton wool. Glue the top of the frame with paper strips 4-5 cm wide. Glue is prepared as follows: in 1 glass cold water dilute 2 tbsp. potato starch. Then gradually add 1 liter of boiling water to this mixture, stirring constantly until the mass thickens. As glue, you can use a sugar solution - 2 tbsp. for 1 glass of water. Instead of stripes, it is used and masking tape.
Rags or plain paper are dipped in a soap solution, the liquid is allowed to drain and dried a little. Then, with a knife or some sharp object, the gaps are filled with the prepared material. Masking tape is glued on top to prevent drafts.
You can insulate windows with paraffin or wax. To do this, it must be melted and then poured into the slots with a syringe. This method is quite reliable and long-term.
Often, ordinary putty intended for wooden surfaces is used to insulate windows. It can be used for painting.
Another pretty simple one. It is fixed with outer side windows all around. Fastening is carried out with a construction stapler. The only nuance in this case- the film must be well stretched, otherwise it can be torn off under the influence of wind.

Seals

The main advantage of the seal is that it does not need to be dismantled, it can last for more than one year, reliably protecting the room from the penetration of cold air through the window. It is laid around the entire perimeter of the window at the joints of the box with the frame.

Most often, seals have a self-adhesive surface on one side, with which they are attached to a wooden base. In the absence of such a surface, a special glue is used. The type of seal is selected according to the size of the slots.

First of all, the frame must be washed and dried well. Freshly painted frames can be pasted over only after two weeks.

Measurements are taken with a strip of sealant, and it is very important not to stretch it. Both ends are cut at a 45 degree angle. After removing a small piece of the protective layer, the sealant is applied to the upper edge of the frame and further, gradually removing protective layer, glued to the bottom edge.

Then the horizontal joints are glued in the same way. At the corners of the frame, it is precisely due to the angle of 45 degrees, under which the seal was cut, that the junction of the horizontal and vertical segments must be made. For greater reliability in these places, the sealant is fixed with a construction stapler.

Mounting foam

This material is used to fill large gaps between the wall and the window structure. The frames should first be strengthened with spacers, since the foam expands during application and the window structure can warp. Next, you need to sprinkle the gap with water.

Foaming is done, starting from the bottom and gradually rising up. The gap is filled with foam to 1/3 of the depth. Then it is necessary to treat the applied foam with water from a spray bottle. Apply another layer if necessary. The excess is trimmed with a sharp knife.

Some time after the foam has completely solidified, the surface must be covered with putty, paint. If the foamed surface is not treated, over time it begins to crumble under the influence of ultraviolet rays. In addition, it is susceptible to moisture.

When working with mounting foam some rules must be observed:

Gloves must be used during work.
The room must be well ventilated.
The air temperature should not be lower than +5 degrees.
During operation, the foam bottle must be shaken periodically.
Hold the balloon upside down.

Sealant insulates the place of contact between glass and window frame. To do this, stock up on new glazing beads and a mounting gun.

The sequence of work in this case is as follows:

Old glazing beads must be carefully removed. The lower glazing beads are removed first, then the side ones, and only then the upper ones.
Remove glass carefully.
Clean the areas of the frame where the glass has been installed and dry.
Fill these places with sealant.
Replace glass.
Install neatly glazing beads

Installation of heat reflective film

This material for warming wooden windows has appeared recently. It is a multilayer film 30-35 microns thick coated on one side with metal (chromium, nickel, silver or gold).

Its advantages are undeniable:

The film is absolutely transparent, its presence on the glass does not distort visibility.
Heat loss is kept to a minimum.
Due to its reflective properties, it prevents the passage of harmful ultraviolet rays.
Protects glass from damage, fogging.
Easy to install.
Wear resistant and durable.
Serves as protection of the dwelling from electromagnetic radiation.

To install it, you need to prepare a set of tools, which include:

Scissors.
Plastic spatula.
Stationery knife.
Spray.
The adhesive tape is double-sided.

In addition, you will need a clean rag, soapy water, and rubber or cotton gloves.

First of all, you need to thoroughly wash the windows and let them dry well. Then release the structure from the fittings - handles, etc. Next, the window is measured, for fixing it is necessary to leave a small allowance of about 2 cm. Cut the film with scissors according to the measurements made.

Before gluing the film, the glasses are wetted with soapy water, wooden elements window construction need to be degreased. Then, along the perimeter, the frame is pasted over with double-sided tape, on which a film is then applied. In doing so, care must be taken to ensure that the metal coated was outside. With a spatula it is necessary to smooth it over the glass, removing air. From above, the edges of the film are neatly fixed with glazing beads.

Then the fittings are installed in place, the adhesive tape is removed. If there are small wrinkles, they can be removed by gently heating the film with a hair dryer. Under the influence of hot air, it will take the necessary shape.

When working with a heat-reflecting film, it is necessary to ensure that dust, dirt or water does not get on it, otherwise it will lose its properties.

Warming is usually done inside outer window frame. The only exceptions are lintels above the windows. They can be glued construction foam outside.
It is impossible to work with sealants in winter, the most suitable time is the beginning of autumn.
Material for insulation should be purchased with a margin. During operation, small flaws are possible, leading to the unsuitability of the material.
In the process of home insulation, windows are given the most important role, since they can cause drafts. Therefore, this issue is resolved, as a rule, in the first place.

Insulating windows for the winter is an invariable ritual that is carried out by the owners of wooden frames before the onset of cold weather, which allows you to increase the temperature in the room by 5-10 degrees and reduce heating losses. There are many ways to insulate windows for the winter, both with the use of special sealants and sealants, and with the help of improvised means available back in the days of our great-grandmothers.

Principles of window insulation

The meaning of insulation is to create the most airtight internal air space between the frames. As you know, air is an excellent heat insulator, provided that it is enclosed in a closed space. This space is the distance between the outer and inner frame. It turns out that in order to insulate windows, it is necessary to eliminate the gaps that allow cold air flows from the street to penetrate.

When insulating wooden frames, three methods are usually used: sealing gum is used, the gaps between the frames are sealed and they are glued with strips of paper, adhesive tape or fabric. At the same time, it is not recommended to seal the outer frame with vapor-tight tape - this will lead to their strong fogging, and in cold weather - to freezing. Internal frames, on the other hand, are best sealed to prevent moisture from penetrating into the space between the frames.

Between the frames, it is desirable to lay an adsorbent - silica gel, Activated carbon, soda or salt. So that they don't spoil appearance windows, they are placed in small white paper bags. However, in a city apartment with normal humidity can be dispensed with without adsorbent. If the humidity is high, it is better to sacrifice the appearance of the windows: moisture, condensing on the glass, flows onto the wooden frames, as a result of which the paint peels off and the frames begin to rot.

Before the start of insulation, windows and frames must be washed and wiped dry, check for large cracks, as well as the tightness of the glass. Poorly fixed glass not only allows cold air to pass through, but also rattles in the wind. If necessary, glass can be strengthened, how to do this is described below.

Glass repair and sealing

It happens that even insulated frames do not protect the apartment from drafts, and most often the problem lies in poorly fixed glass. Previously, glasses were framed on window putty, which looked like dirty gray hardened plasticine. Over time, due to temperature and humidity changes, the putty begins to dry and crumble, and after a few years or decades it does not remain at all. At the same time, the glasses begin to rattle, and large gaps are obtained between them and the frame. Silicone sealant will help to correct the situation.

Repair and insulation technology:

Assess the condition of the glazing beads - rails that hold the glass in the frame. If they are rotten, stagger and crumble, it is better to immediately buy new ones in the required quantity.
Gently pry the glazing beads and pull them out along with the nails. Take out the glass.
Clean the frame from the remnants of old putty and excess paint at the place where the glass was installed.
Remove putty residue from glass with an alkaline solution such as soda ash. It is not recommended to scratch the glass with a knife, as this will leave scratches that cannot be removed.
The frames are wiped dry and smeared around the perimeter with a transparent silicone sealant, after which the glass is installed.
The glazing beads are nailed into place using window nails. This must be done very carefully, trying not to pinch the glass, otherwise it will crack when the temperature drops.
The remaining cracks are also smeared with sealant, removing its excess with a damp cloth. Let it dry for 2-4 hours. After that, the windows are wiped using a window cleaner and the frames are insulated.

Window insulation materials are sold in hardware stores; they are a narrow sealing tape with an adhesive layer of foam rubber or soft polymer. Sealing tapes made of polymer materials can be used for several years, while you can open windows, wash them without removing the tape. The foam insulation gets wet when it gets wet, so it is better to remove it annually.

How to glue sealing tape? This process is very simple: a sealant is glued around the perimeter of the open window sash with an adhesive layer applied to it, after which the frames are carefully closed with locks. This is done with both external and internal frames; with large gaps, windows from the inside can be additionally glued with masking tape - it is also sold in household goods stores.

Insulation of windows with large gaps

If the frames are too old or severely skewed, they may have huge gaps that cannot be covered with sealing tape. In this case, you will have to caulk the cracks with cotton wool, foam rubber, rags or paper, or putty them with special mixtures. It is done like this:

Window insulation with putty

A more radical method, which allows you to qualitatively insulate not only windows, but also cracks in window sills, is to use building mixtures. For this purpose, putty can be used on glue base, a solution of alabaster mixed with chalk in a ratio of 1: 1, as well as window sealants.

The selected mixture is applied to the cracks with a metal spatula, leveled and left to dry completely. It should be remembered that the removal of such putties can lead to peeling of the paint, so this method must be used carefully. However, it is very effective for old frames that are supposed to be replaced soon - it is often impossible to insulate them with a sealing tape, and putties and alabaster mortar perfectly seal the space between the frames.

You can also use moisture-resistant sealants for outdoor use, while choosing white or colorless. The sealant is applied directly from the tube, smearing all the cracks with it, as well as the joints of the glass and the frame.

Cardinal method of window insulation

If you don't plan to ever open a window, you can use foam. The cracks are filled with it, they wait for it to expand and solidify, after which the excess is cut off with a sharp knife. To avoid yellowing and destruction of the foam, it is covered with ordinary white enamel for outdoor use.

In practice, this method is used extremely rarely, and mounting foam is usually used for insulation. window frame, filling her gaps between her and the walls. This operation is performed at the stage of installing windows, but if you think that heat loss occurs precisely for this reason, you can open the window sill, window slopes and ebbs and foam window frame.

Video - how to insulate wooden windows for the winter?

Greetings. In this article I will talk about how and how to insulate wooden windows for the winter. There are many ways to make old windows more airtight, but, as practice shows, not all of them are equally good. Consider those methods that you can apply on your own and decide which one is the best.

Ways to do it yourself

Among the methods suitable for thermal insulation of windows, I note the following:

Filling gaps with mounting foam;
Sealing technological gaps with window paper or adhesive tape;
Pasting of glazing with thermal film;
Installation of a sealant on an adhesive basis along the line of the porch;
Sealing glass in the frame using sealant;
Installation of the seal along the line of the porch into a milled groove.

The listed methods of insulation provide the greatest efficiency if they are used not separately, but in a complex.

Method one - use mounting foam

This method is suitable for you if the windows are old, and with the onset of warm weather, they are supposed to be replaced with new double-glazed windows. The fact is that having processed the technological gaps with mounting foam, it will then be impossible to open the sashes.

Warming instructions are as follows:

We open the inner and outer sashes, and clean the perimeter of the porch from dirt - the area where the sash adjoins the frame;

Lightly moisten the perimeter of the porch with water from a spray bottle;
Carefully apply foam from the balloon around the perimeter of the porch, while trying not to get on the glass and on the windowsill;

We close the sashes by turning the handles all the way and inserting the latches;
We perform a similar procedure with the porch window;

After the first row of glazing is strengthened, we wait for the foam to dry and cut off its excess;
If necessary, we carry out insulation on the second - the inner row of glazing.

Even one row of glazing after processing with mounting foam will not only be insulated, but also isolated from noise. After the second row of glazing is insulated, the window will not see through at all and let in sounds from the outside, since there will be no gaps at all.

Please note that a window insulated with mounting foam will not be suitable for ventilation. Therefore, you will need to take care of others no less effective ways ventilation.

Method two - seal with tape or paper

This method of insulation is the simplest and probably the most budgetary. To seal windows, you will need a regular (not masking) wide adhesive tape or special paper tapes for pasting windows. If you decide not to spend money at all, you can use old newspapers cut into strips as a material for sealing gaps.

Why do I recommend using ordinary tape instead of masking tape on old windows? Ordinary plastic tape is completely sealed, unlike the paper counterpart. In addition, ordinary adhesive tape adheres much better to various surfaces and better hold on them.

The gluing instruction involves cleaning the perimeter of the junction of frames and sashes from dirt and flaking. Then the adhesive tape is glued at the beginning of the gap, gradually unwound and glued along the entire gap. It remains to carefully iron the perimeter of the gluing with your own hands so that the adhesive tape adheres well to the surface, and the work can be considered finished.

If there are cracks in the old glazing, do not be too lazy to immediately seal them with wide adhesive tape from the outside and from the inside.

With newspaper strips or with special paper, everything is a little more complicated, since you have to pick up glue or prepare a paste. For these purposes, leftovers are suitable wallpaper glue or paste from a small amount of flour diluted with water. If newsprint is used, you can make a thick soapy solution and glue wetted strips onto the frame.

The method is good because its price is cheap, but there are a couple significant shortcomings. With the onset of the warm season, when dismantling the strips, fragments may come off along with the insulation paintwork. Mold or fungus may appear on strips of paper glued with flour or starch paste.

Method three - gluing thermal film

The use of heat-saving film is not new technology. AT country houses, many years ago, a translucent oilcloth was stuffed from the inside of the frames through a glazing bead.

As a result, more or less isolated additional air chamber. The disadvantage of the solution was low visibility through a translucent oilcloth and a low degree of light transmission.

The modern version of mounting the film on the windows is preferable, because the polyethylene is absolutely transparent and even. And, most importantly, during installation, you can do without a glazing bead and not spoil the frame.

Installation instructions for a thermal protective film purchased in a special kit are as follows:

Remove the handles from the inside of the window sashes;
If necessary, we pass with fine sandpaper, removing protruding irregularities from the surface of the valves;
We clean the prepared surface from dirt and dust;
We glue double-sided tape along the perimeter of the wings, carefully pressing it so that it does not move away from the surface anywhere;

After the tape is glued, carefully remove the outer protective film from it;

We straighten the thermal protective film, apply it to the frame and glue it to the adhesive tape;

With a household hair dryer, we heat the glued film around the perimeter of the frame so that it aligns and better sticks to the adhesive tape;

With the same hair dryer, we heat the main surface of the film and disperse the remaining wrinkles;
We fasten the handles in place and along the edge of the glued adhesive tape, cut off the excess film.

Method four - the use of a rubber seal

In this instruction I will show how to glue the tubular insulation along the porch line. However, using a similar instruction, you can paste over the frame with solid rubber seals and foam rubber.

The installation instructions for the seal are as follows:

We open the sashes, in the porch of which we will carry out gluing wide open;

With a chisel or knife, we clean the remnants of old seals from the porch or simply level the surface so that there is a protrusion with a right angle along the perimeter of the frame;
Next, knead the usual plasticine into balls with a diameter of 2 cm;

We glue plasticine balls into the porch around the entire perimeter at a distance of 30 cm from each other;
We cover the sash until it stops, and then open it;

We remove the lumps of plasticine one by one and examine how deformed they are;

The recess on each of the plasticine lumps is the degree of pressing the sash to the frame. That is, the side of the recess is equal to the thickness of the seal to be selected. Therefore, we examine the removed lumps, determine the smallest value and select the sealing cord from it.

We transfer measurements from lumps of plasticine to paper for calculations, which cord and in what quantity to buy in order to ensure a tight porch of the sash;

From the end of the cord, we separate the protective tape and apply it to the frame from the corner;
Gradually removing the protective tape, apply and level the sealant;

We insert the edges of the tubular seal into each other so that they do not stick out and do not peel off.

Method five - sealing the glass in the frame with a sealant

Another problem with old windows is that the glazing bead around the perimeter of the sash does not press the glass tightly enough. As a result, when opening and closing, a bounce is heard. But it’s not so much the rattling that is terrible, but the fact that the gap between the glass and the glazing bead lets cold air in from the outside and contributes to the formation.

You can completely dismantle the old glazing bead and install a new one. If long-term window repair is not your plan, I recommend using a sanitary silicone sealant.

By pressing on the glass, we squeeze out the sealant so that it enters the gap from the tube spout. After walking along the perimeter of the glazing bead, stop pressing on the glass and gently wipe off the excess sealant that will squeeze out from under the glazing bead.

Method six - warming in Swedish

Insulation of windows using Swedish technology is the same use of tubular insulation. But, unlike the previous instructions, the sealant is not glued to the wood, but inserted into a special milled groove and held there by spacers or seals on the edge.

Swedish window insulation technology is not limited to installing a cord. In addition, the sashes are adjusted to the frame so that there is no distortion and gaps, and if necessary, the old fittings are replaced with new ones.

Instructions for warming according to Swedish technology are as follows:

Along the perimeter of the narthex, a groove is cut with a milling cutter (depth 8 mm, width 3 mm);
Starting from the corner of the sash or from the beginning of the mounting plate, insert the cord into the groove with the mounting edge forward;

We roll the cord with a special roller, gradually inserting it along the entire length of the groove.

The advantage of the technology is that the cord is firmly held in the groove, which means that it will not move away from the sash longer, unlike the glued seal. There is also a drawback - for warming according to Swedish technology, you need a special tool.

Agree that it is unprofitable to purchase a milling cutter and a pressure roller for performing one-time work.

Conclusion

From the article you learned how to insulate windows for the winter, and you can choose the method that is suitable for self-fulfillment. I also recommend watching the video in this article. If you have any questions about the proposed instructions, write about it in the comments.

How to keep warm in the house? This topical issue everyone is asked - residents of urban high-rise buildings, the private sector, owners country houses and country cottages. In winter, the cold strives to enter 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 sealed 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. The high cost of energy 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 universal insulation any improvised materials acted. 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 the level of humidity.

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 - 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 placing an 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;
filling voids with 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 a construction gun to apply sealant;
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 an 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 is the tightness of the 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 using modern techniques, gluing and other traditional techniques lose 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 on the outside of the frames, which significantly reduced the level of illumination of the premises. Modern films are distinguished by thinness, transparency and ease of installation: 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 pick suitable materials for window insulation and will carry out the practical implementation of advice and recommendations.

Wooden windows are replaced with new ones made of PVC or metal-plastic, for the reason that they lose their ability to retain precious heat in an apartment or house. When installing a double-glazed window, few people are interested in how it will behave in the future. Will it let the cold through, is it necessary to carry out insulation, how effective is it.

Many consumers are wondering how to insulate a plastic window. Like any other design, metal-plastic or plastic system has weaknesses. They act as a direct way for heat to escape from the room.

Why is it blowing? This is a question often asked by homeowners. If you are also one of them, then you should consider the main nodes and deal with design features window block. The most common places to inflate are:

rubber compressor;
perimeter window frame;
window glazing bead;
window fittings.

In order to determine where the air is blowing from the plastic window, you must run your palm over the surface of the block. You can also use a lighter. The last procedure is very simple. It is similar to the previous one. The fire will be sensitive to drafts, so you can detect blowing.

Before insulating a plastic window, you can take a sheet of paper and clamp it in the sash. If you pull on the corner, you can easily pull out the sheet. In this case, we are talking about insufficient sealing of the double-glazed window. This indicates that the seal is poorly pressed against the frame.

Why is it blowing from the window

Many consumers eventually wonder why it starts to blow out of a plastic window. There can be many reasons. Among others, it should be noted:

installation error;
skewed double-glazed window;
physical wear of window components;
violation of the rules of operation.

The most common cause is an installation error. It may be due to non-compliance with technology. Sometimes it happens that the window is simply skewed. This problem remains relevant for residents wooden houses and new buildings.

Window components may experience physical wear and tear. This is especially true for rubber seals. In order not to decide over time the question of how to insulate a plastic window, you must properly operate it. The seal must be washed and treated with glycerin from time to time. Such care will prevent loss of elasticity and cracking of the material.

What can you do yourself

If you want to solve the issue of blowing, then you can replace the seals with your own hands, insulate the contours of the frame, and insulate the window opening and window sill. It is necessary to do this work before the onset of cold weather. This is due to more comfortable conditions for work, optimal humidity, material requirements, lack of drafts and reduced risk of getting a cold. When it is warm outside, you can perform not only outdoor, but also internal insulation.

If you are thinking about the question of how to insulate a plastic window, then first you need to choose a material. For this, they are usually used:

mounting foam;
mineral wool;
Styrofoam;
expanded polystyrene.

The first option allows you to fill all the voids around the perimeter of the opening. This approach will eliminate the movement of air. Foam is 90% air, so it will be an excellent insulation. But in a frozen state, it must be protected from ultraviolet radiation, low and high temperatures.

The mineral wool will great solution for thermal insulation of internal slopes and window sills. It has a limited range of use for insulation. As for the foam, it is widely used for slope insulation. Rigid insulation is advisable to use when the thickness of the mounting seam is not more than 3 mm. In all other cases, it is better to purchase mineral wool.

If you want to solve the problem of how to insulate plastic windows for the winter, you can consider silicone sealant. It will eliminate the blowing between the elements of the double-glazed window. Dry mixes for slopes are also widely used. With their help, you can also carry out thermal insulation from the outside. But if you purchase construction tape, then it will need to be glued on top of the sealant. Sometimes it is used as an independent heater.

Preparation for thermal insulation of the window unit

In order to insulate window block you need to prepare:

sealant;
sealant;
construction tape;
heat-saving film.

The latter is also called energy saving. An excellent way of thermal insulation will be mechanical methods. This should include adjusting fittings.

External slope insulation

Quite often, owners of houses and apartments are wondering how to properly insulate the slopes of plastic windows. The first step on the road to improvement thermal insulation properties design becomes dew point offset. This will eliminate the appearance of dampness and the development of fungus.

You can cover up the cracks, but this measure will be temporary, since over time the plaster will crack and open the mounting foam. The latter, under the influence external factors will start to break down. Plaster can cover the insulation, protecting the layer from atmospheric phenomena.

First you need to prepare a hard insulation and clean the surface of the slopes from protruding parts and dirt. The base is primed. On the adhesive solution or foam insulation is installed. It is better to use foam, as it eliminates the need for wet work and sets in a short time. With it, you can strengthen the insulation sheet as firmly as possible.

If you are faced with the task of how to insulate the slopes of plastic windows, then you will need to seal all the cracks with glue, install a perforated corner, a polymer mesh and finish the surface with plaster. When installing a layer of thermal insulation, it is necessary to ensure that the material overlaps part of the window frame and protects mounting seam.

Thermal insulation of ebbs

If you want to insulate the ebbs, then it will be enough to fill the gaps with foam or place heat-insulating material inside. In order to protect it from contact with moisture, it is necessary to mount a metal ebb bar on top. It is at an angle of 5°. The horizontal edge must extend beyond the facade by 30 mm. The side edges are wrapped up. The place where the bar will adjoin the surfaces must be treated with a sealant.

Internal thermal insulation

If you are among those who want to insulate a plastic window inside, then you should take care of the slopes, which are not so affected by external factors, but can still become a place through which heat escapes. It is important to keep the slopes aesthetically attractive.

First you need to process the cracks, remove dirt and old foam. A primer is applied to the surface. The slots are filled with mounting foam. Its excess after drying should be removed. Next are installed thermal insulation materials. They can be cotton wool or polystyrene. On the next step you can start installing drywall. It is important to produce finishing its surface, covering with putty and painting.

Window sill thermal insulation

If you want to insulate plastic windows for the winter with your own hands, then you can also do a window sill. The gaps between it and the wall are a place of significant heat loss. Before starting work, it is important to determine weakness this part of the window block. Blowing can be between parts of the window and the window sill.

In this case, a sealant is usually used. Heat can go to the place between the wall and the window sill. In this case, thermal insulation should be carried out before installing the window sill by laying an insulating layer. After finishing installation work distance between concrete or brick wall and window sill can be filled with foam.

Warming by adjustment method

If you want to resolve the issue of how to insulate plastic windows with your own hands, then you can act in a comprehensive manner. For this, in addition to the above methods, adjustment is usually used. You can eliminate the skew of the sash.

Some property owners change the seal. You can do it yourself. old material is pulled out, and a new one is installed in the groove. Before that, you must decide which sealant to choose. After reviewing the assortment, you will understand that black and gray seals are on sale. The former are more plastic, while the light shade is due to the presence of additives that reduce the price and worsen the properties. The material is not so tight at the moment of pressing.

Alternative ways

If you still cannot decide for yourself the question of how you can insulate plastic windows with your own hands, then you can use more simple methods. To do this, many use thick curtains that retain the ability to retain heat indoors. Sometimes improvised means are also used, but some of them can spoil the appearance of the double-glazed window.

As a heater are used:

window tape;
soaked paper;
foam rubber;
strips of white fabric.

You can purchase heat-saving film, which is also called energy-saving. It is glued to the sash. It is important to exclude the formation of air bubbles and the formation of folds. The film can reduce heat loss by 75%.

If you want to understand how to properly insulate plastic windows, you can use electric heating. In this case, a heating cable is located around the double-glazed window, which will heat the spiral. Sometimes it is installed on the window oil radiator. Most in a technological way is the electric heating of the double-glazed window.

You can install heated windows. This technique used during production. It provides for the installation of a conductive film on the inside of the glass. It is transparent and contains conductive threads. In this case, the glass is heated from the inside. If you still have not decided how to insulate plastic windows for the winter, you can use an integrated approach. It is the most appropriate in a private house or apartment, as it allows you to eliminate possible reasons heat leakage.

Using a special tool

For insulation, you can use the method of adjusting the pressure of the valves. For this, an eccentric is used. Elements are installed around the perimeter. To ensure a tight clamp, the eccentric scrolls clockwise. There are risks on the elements. When they are facing the street, this indicates a weakening of the pressure. If the pointer is facing the seal, you will ensure that the sash is well pressed against the structure.

It is also important to pay attention to the loops. They have their own mechanism. It provides grip. When adjusting the device, you will need to use a hex key. By sliding the tongue, you can ensure a snug fit of the sash. To extend, turn the hex counterclockwise. When the loop is on the right, the rotation is carried out in the other direction - clockwise. It is very easy to eliminate the skew of the valves.

Finally

Now you know how to insulate the slopes of plastic windows inside. For an integrated approach, it is necessary to pay attention to the window sill. Experts do not recommend other works on thermal insulation.

You should also be prepared for the fact that insulation can adversely affect the ventilation in the room. Full tightness is not only protection against cold, but also fogging of glasses, which causes the destruction of slopes and the occurrence of fungus.
