Window structures made from polyvinyl chloride are self-sufficient products that do not require additional thermal insulation.

If you are increasingly thinking about PVC, because in winter they still allow the cold to pass through, then there is definitely something wrong with some of the structural elements. Let's look at this issue in more detail.

What does a PVC window consist of?

Any plastic window structure includes the following components:

profile;
rubber seals;
glass unit;
adjustment fittings;
there is a window sill at the bottom and slopes on the sides.

If a breakdown occurs in one of the listed components, there will be blowing.

What does thermal insulation come down to?

Insulation of plastic windows consists of slopes. In the context of other elements, this is only about troubleshooting. Due to the profile, for example, drafts never occur. Modern high-tech plastic is not wood. The material cannot dry out or move.

Double-glazed windows lose heat if depressurization occurs in certain areas of the product. If you don’t want the windows to let the cold in, insulate the slopes or look for the cause of the breakdown. Let's start looking at the insulation of window structures with slopes.

Protecting slopes from the cold

For plastic windows, it is advisable to make slopes from plastic. It is best to line them with hard plastic. Why? The material is excellent for additional thermal insulation.

In this case, the opening that appears between the wall surface and window frame, filled with special foam. Other options are foam insulators or slabs made from basalt fiber. Choose a material that suits your current tasks.

External and interior wall also needs to be insulated. Only this time the materials are no longer insulating, but protective properties. From negative impact various external factors protects the insulator directly.

Elimination of sash misalignment

Window and wall structures sometimes shrink. Unfortunately, nothing can be done about this. New buildings especially suffer from this “illness”. Shrinkage, in turn, leads to a slight distortion of the valves, which negatively affects the thermal insulation of the structure. The solution to the problem is debugging the hardware.

Tool

You can adjust the pressure of the shutters yourself using special eccentrics. When turning the hand, they go behind the “calling pads”. These elements are installed along the frame perimeter. To ensure tight pressing, the eccentric is rotated clockwise.

Each element described has a risk. When she “looks” towards the street, this indicates a weakening of the pressure. If the pointer is facing the rubber seal, the sash is pressed well against the frame structure.

Loops

The hinges of a plastic window also have their own mechanism responsible for the pressure. The device is adjusted using a hexagon. The rule is simple: a strongly retracted tongue means a tight fit of the sash. To extend it, you need to turn the hexagon counterclockwise. When the loops are located with right side, the turn is made in the other direction. This time clockwise.

As you can see, there is nothing complicated - the misalignment of the valves is eliminated easily and simply.

If the described actions do not help, and the cold does not go away, it means that more serious problems have arisen. In this case, you will have to contact the experts.

Preparing the window for winter:

Replacing the rubber seal

What is a rubber seal? Its main task is to ensure a tight fit of the sashes to the frame. For greater reliability, it is made of rubber and does not allow cold to pass through when closed.

If you properly care for it and regularly treat it with special compounds, the seal will last quite a long time. However, few owners of PVC windows take care of the element, which is almost always hidden by the sashes. Many people don’t even know that it needs to be lubricated with special mixtures.

So it turns out that in about five years the rubber seal loses its density. And when a product becomes unusable, it must be replaced.

To perform the replacement, the glass unit is removed from the sash. We remove the glazing bead and take out the required element. Rubber compressor changing is simple: the old one is removed, the new one is inserted through the groove. If desired, secure the product with adhesive. Don’t be confused by the color difference - insulation is made from black and gray rubber, but there are no differences.

Attention! Be extremely careful when removing and inserting the bead. The element is easy to break as it is very fragile. If the glazing bead becomes unusable, it will not be possible to install the double-glazed window back.

Alternative insulation methods

In addition to all the methods listed above, some tricks can help prevent the cold from getting in. Let's look at a few of them.

Wool blinds

It's slightly unconventional, however effective method insulating windows with your own hands. Regular blinds are simply wrapped in strips wool fabric, thanks to which they become reliable protectors from the cold penetrating through the windows in winter.

Heat-saving film

Insulation of plastic windows can also be done with heat-saving film - quite inexpensive and at the same time effective option. But you need to glue the film so that there is no air left under it, that is, “bubbles”; not only will this depend on appearance windows, but also the quality of thermal insulation.

This is the most modern way insulation of the room. With such a system, it is placed on the windowsill oil heater, and an electric heating coil is installed in the glass itself.

But if you decide to use just this heating method, then it is better to complete the installation while the double-glazed windows themselves are still being installed, but you can do this later by purchasing the system in a specialized store.

Curtains

It may sound strange, but curtains can protect you from the cold. They serve as an effective barrier to air and keep out the cold in winter if it does penetrate through the windows. In addition, passing through the curtains, the air, although not significantly, warms up.

Window sill insulation

Cold air can also penetrate through the joints between the adjacent parts of the window sill. They need to be sealed well. Also, if the work is done poorly, “black holes” may remain under the window sill itself, so it must be dismantled and the joint between the slab and the window block must be further processed.

To do this, we open the small plugs on the window sill, unscrew it with a screwdriver, and all possible cracks are revealed to us from where cold air can come.

Results

Remember one simple thing– if a plastic window loses heat, there is a problem with one of the elements of the system. Eliminate the problems, the structure will regain its lost properties.

The only thing that requires full insulation is the slopes and, possibly, the window sill. No other thermal insulation work is required. PVC windows are already protected from the cold to the highest level, as they were originally designed to create a comfortable atmosphere in any room.

It is no secret that a huge amount of heat escapes from rooms through windows - this is especially noticeable in winter period. Consequently, it is these structures that need protection, and the sooner it is done, the better. Fortunately, such work can be easily done on your own, and if you don’t have time for it, just hire specialists. Even our distant ancestors were aware of how to properly seal cracks in window structures - their houses were warm even in severe frost, but little wood was required for heating. However, insulating plastic windows for the winter is somewhat different from traditional solutions, which were popular decades ago, the technologies in our time are different, the approaches to solving problems are also chosen by modern ones.

We insulate plastic windows

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

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

Blinds and insulation

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

Electric glass heating

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

Why do you need to insulate slopes?

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

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

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

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

In what cases is it necessary to insulate slopes?

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

How slopes are insulated

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

Sheets of insulation are glued along the top of the slopes; moreover, a plaster mesh should be secured on top. A cement-sand mixture is applied to it in a thin layer, then finishing putty to consolidate the result.

Foam insulation

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

Swedish technology

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

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

When to make adjustments

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

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

Now many people are changing wooden windows to plastic ones. However, during operation their tightness may be compromised. People are faced with the question of how to insulate plastic windows so that the violation of integrity is corrected, and air from the street penetrates less into the room. It is important to understand what is the cause of the problem and solve it, and then do the insulation.

Why does it blow from plastic windows?

Before you begin to correct the current situation, you should find out why the blowing occurs and whether there is fogging. There are many reasons, but there are several main ones:

Defect in production.
Low-quality plastic was used to make the windows.
Poor fittings were installed.
Errors were made during installation.
Poor quality of seal material.
The slopes were not properly insulated.

How to determine the cause

First, let's make sure that there is definitely a breeze from the window. To understand this, you can hold a lit candle or lighter to the junction of the window sash and frame. If the flame fluctuates, it means it is blowing from the window. Then the candle should be drawn around the entire perimeter. The problem often occurs at the junction window frame and slope. This indicates poor installation, so you need to contact the company and demand that the work be corrected (if the warranty period has not expired).

The reason may lie in incorrect adjustment of the fittings or lack of installation on winter mode. To do this, try opening the window and looking at the lock. Not everyone can independently determine the problem and make adjustments, so it is better to call a specialist. Sometimes the reason is a violation of the window geometry. In this case, there is poor pressing of the sashes, and drafts arise due to this connection. A complete reinstallation of the glass unit will be required.

Another diagnostic method is to check the condition of the seal. It probably causes moisture to blow in or leak (condensation forms) if Bad quality or very dirty (remove all dust). When exposed to low temperatures, it loses its elasticity. You should touch it with your hands, checking for elasticity. If the reason is wear and tear of the insulation, then it needs to be replaced.

The next step is to pay attention to the quality of the plastic. Unfortunately, the average person will not be able to visually distinguish high-quality plastic from bad one; this requires a specialist. However, if all of the above diagnostic methods did not reveal the cause, then most likely you bought windows from bad material. We will have to dismantle and install a new metal-plastic structure.

When is the best time to isolate?

The problem of window blowing occurs during the cold season. IN summer period people either don’t notice it, but with the onset of cold weather the air from the street becomes noticeable. It is best to do thermal insulation in spring or summer in calm weather. The sealing compound requires a special temperature and cannot be used in winter weather. There is an advantage of insulation during the cold season: it is clear which place to insulate and whether the chosen method is effective.

How to insulate plastic windows

It is extremely important to understand how to insulate plastic windows. There are many methods of thermal insulation, so everyone can choose one that is convenient for themselves. Insulation for plastic windows is as follows:

Polyurethane foam is a fast and affordable method. However, foam is short-lived and is negatively affected by temperature changes, ultraviolet radiation, air.
Mineral wool is a safe and fire-resistant modern material.
Window film is good to use as insulation for the glass itself.
Silicone sealant is reliable and inexpensive.
Polystyrene foam is used to eliminate cracks in window slopes.
Warm mixtures used outside.
Gluing construction tape over the sealant will improve the effect.
Facade paint has high weather resistance. It is easy to apply to a surface of any shape.
The primer dries quickly and is easy to apply. It is frost-resistant and is not afraid of moisture.

When you can't do without a master

A professional is needed when there are obvious defects, and work to eliminate them requires compliance with safety regulations. To carry out repairs, it is worth calling a specialist because:

insulating slopes and ebbs from the outside can be dangerous, especially if the window is located above the second floor (you can fall and break);
in order to properly insulate, it is important to know the entire installation process;
The window is still under warranty.

Do-it-yourself insulation of plastic windows for the winter

A professional will advise you on how to seal plastic windows for the winter. However, there are simple and easy ways you can make repairs yourself. A simple example is the thermal insulation of a window using foam or sealant:

Remove old foam from all openings around the window. To do this, use a stiff brush, sticks and brushes.
Thoroughly rinse and wipe the surface of the window sill and slopes with a cleaner to degrease and remove dust.
Cover the resulting cracks with putty and plaster, then fill polyurethane foam.
If sealant is used instead of polyurethane foam, then after inserting it into the gap, it should be sealed with construction tape on top. To carry out the work, you must have a knife and scissors at hand.
Install heat-saving film. The window frame is cleaned of dust and covered with double-sided tape. The film is measured to the size of the window, then carefully applied and smoothed. To avoid unevenness and bubbles, you need to blow it with a hairdryer.

Outside

Insulation from the street side can be done in different ways, suitable facade paint, primer, silicone sealant. It is best to use foam plastic for thermal insulation of slopes from the outside:

Styrofoam the right size it is necessary to stick it on the slopes, and close all visible cracks with glue.
A special mesh should be placed on top of the foam and then plastered.
Level the plaster with a water-repellent layer and apply a primer.
Paint the resulting slopes, which will create an additional energy-saving protective layer from the wind.

Inside

The insulation of plastic windows inside should be done as carefully as possible, using different ways. Thermal insulation will contain the following stages:

Insulate the slopes of plastic windows inside. To do this, use polyurethane foam.
Place plastic on top of the foamed slopes.
Adjust the fittings. This is done using an eccentric through rotation.
Replace the seal. This element must be changed every 5 years. During this period, it loses elasticity and begins to let air through.

How to insulate the window sill of a plastic window

Under the windowsill you can often feel the movement of cold air. If a crack is visible, it needs to be foamed. It will be good if you attach a piece of plastic under it and fill the void inside with polyurethane foam or polystyrene foam. Stages for insulating a window sill:

Remove the window sill.
The wall on which it was located should be thoroughly cleaned of dirt and dust, after which all cracks and problem areas will be visible.
Cracks can be closed with polyurethane foam.
When the foam hardens, cut off the excess with a knife.
Prime the entire surface.
Apply sealant to all joints and corners.
Plaster.
Place the window sill in place.

Many people have a question about how to insulate plastic windows for the winter. This problem must be approached with all seriousness. Plastic windows without high-quality insulation are a source of heat loss from the premises. The entire range of work on their insulation can be done independently or hired specialists.

Insulating plastic windows both in an apartment and in a private house allows you to reduce the heat loss of the building several times. Many problems arise at the installation stage due to errors by craftsmen or incorrectly selected materials. Therefore, the installation of a plastic window should be trusted only to professionals who provide a guarantee for their work. But if after installation during operation any defects were noticed, they should be identified and corrected.

At high-quality insulation Plastic windows for the winter can prevent drafts in the room. Also, in this way it is easy to increase the temperature in the house by several degrees without additional heating costs.

PVC or Euro windows can be insulated all year round, but it is best to do this in summer, late spring or early autumn. The optimal weather for carrying out the entire complex of work is dry and windless. This will allow you to achieve highest quality thermal insulation and will extend the service life of installed materials.

You also need to understand that only minor defects can be corrected on your own, while serious problems are best left to a professional. For example, work on insulating slopes or ebbs, if the apartment is located above the 2nd floor, should be carried out by specialists. Doing this on your own is life-threatening. Also, if any defects are eliminated, a person automatically loses the warranty from the manufacturer of the plastic window and its installer. Therefore, before any work, it is better to find out whether they can be repaired for free, without involving third-party companies.

How to identify problem areas?

It is very easy to detect heat leaks. You can use a regular lighter. If there is a draft, the flame will change or simply go out. Also, heat leaks can be easily detected without additional equipment. It is enough to run your hand along the contour of the plastic window and in the area of the window sill to feel the movement of cold air. The most common problem areas are the following:

seal placed along the contour of the sash;
the area of the window block where the glazing bead is located;
area where window unit adjacent to walls, window sills, sills and other structures;
areas where any headset is installed;
a section of wall under a window sill, ebb or slope.

How to eliminate a leak in the seal of plastic windows?

How to insulate windows without the help of professionals? Sometimes it is enough to eliminate all heat leaks by creating a completely sealed structure. This can be done in the following ways:

you need to check the glazing bead. If it is the source of the problem, it is necessary to dismantle the unusable part and put a new one in its place. This is very easy to do with a spatula. Beading can be ordered from a window manufacturing company or purchased at any store that sells profiles;
If a defect is detected, it is necessary to replace the entire seal along the contour of the sash. To do this, you need to carefully remove the glazing bead, remove the linings and remove the glass unit. Only then will it be possible to remove the unsuitable seal. New tape should be cut according old part, adding 3-5 cm as margin. The sealant is placed on former place, but during the installation process you do not need to pull it too hard or press it. All excess should be removed and all structural parts should be installed in the reverse order;

If there is a problem with the adjustment screws near the plumb line, a screwdriver should be used. One of them is necessary to fix the position of the sash, and the other to determine the degree of pressure. To get rid of heat leakage, the first screw must be loosened as much as possible. The other clamp must be tightened clockwise until it stops. The correct adjustment of the screws should be checked with the same lighter;
if the problem is in the slopes, first they should be carefully inspected. If large cracks are identified, it is recommended to use tow or any other insulating material. They are placed in the gap, secured with alabaster. It is also recommended to knock on the surface of the slopes to identify possible voids that must be eliminated in the same way;
if the cold oozes from the window sill, you should carefully insulate the gap that forms near the wall. It can be covered up cement mortar or cover it with wallpaper.

What materials can be used to quickly insulate windows?

How can you insulate plastic windows without the help of specialists? It’s not that difficult to do, the main thing is to choose quality materials and carefully study the technology for performing the work. It is also recommended to watch several training videos, especially if you do not have relevant experience.

You can insulate plastic windows for the winter with your own hands using the following materials:

polyurethane foam. Helps eliminate gaps between the glass unit and the window opening. It only works effectively if it is protected from external influences using other insulating materials. Polyurethane foam quickly collapses when exposed to direct sunlight or wind;
mineral wool. Counts modern material, which has high thermal insulation properties. With its help you can insulate the window sill;
silicone sealant. Necessary for eliminating the smallest cracks that can be sources of cold air entering the room;

Styrofoam. Effective insulation for plastic windows, with which you can eliminate large gaps or prevent cold penetration through slopes;
heat-saving film. If the question arises of how to insulate double-glazed windows with minimal investment, you need to use this particular material. This film is glued directly to the glass and helps retain up to 80% of the heat that is lost through window openings;
construction tape. Allows you to achieve better sealing after applying the sealant;
heat-insulating plasters or paints. They are applied to the surface of slopes as an insulating material.

Technology for performing window insulation work

When insulating plastic windows with your own hands, you must follow the following technology:

It is necessary to remove the old mounting foam, which is recommended to be done around the entire perimeter of the window. To complete the work, it is recommended to use a stiff brush, spatula, or brush. Remaining foam can be removed with a vacuum cleaner.
It is necessary to degrease the surface of the window sill and slopes with a special cleaner.
All cracks must be filled with foam. After hardening, it is recommended to cover it with plaster or putty with additional application of protective paint.
If cracks are eliminated using sealant, you should use a special mounting gun. Only after it has dried (after 5-7 minutes) should the treated areas be additionally insulated with construction tape.
At the final stage, you should begin installing the thermal insulation film. Before performing all work, you need to thoroughly clean the window and stick double-sided tape around the perimeter. To separate the film, use a utility knife. Before gluing it, you need to determine the size of the window, taking into account the tape, and cut the required piece accordingly. To better fix the film to the surface, it is recommended to use a hairdryer.

How to insulate slopes?

How to insulate plastic windows so that they do not let in the cold from the street? When performing thermal insulation work, many people forget about slopes and window sills. Often they are the main source of heat loss.

To insulate them you need to follow the following technology:

The surface of the slopes should be cleared of old plaster to get to the base - brick or concrete. If the coverage is good condition, you don't have to do this.
A plaster solution is applied to the surface of the wall, in which it is advisable to embed the reinforcing mesh. This will increase the strength characteristics of the resulting coating.
After the plaster has dried, you can begin installing the foam. An adhesive composition should be applied to the heat-insulating sheet, and then pressed against the surface of the slope. The seams between the foam plastic must be covered with the same solution. The insulation is installed similarly on the horizontal part of the slope.
You can cover the foam with putty, drywall or decorative plastic panels.

Such simple methods you can protect your home from heat loss.

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

Why do you need insulation?

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

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

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

ease of application.

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

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

How to stick film

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

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

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

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

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

Main mistakes

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

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

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