Do-it-yourself insulation of metal-plastic windows. Window insulation: what are the possibilities? How much does it cost to insulate plastic windows?

The appearance of drafts in the house is always unpleasant, especially if such a problem appears in the cold season. Replacing old windows with new ones is an excellent solution if your windows do not provide sufficient heat and sound insulation and cause a lot of trouble. Modern windows from quality materials installed in compliance with all installation standards do not require additional insulation.

The main reasons for insulating and repairing windows

The reason for such defects is poor quality material from which the product is made.

A temporary solution in this situation will be to seal the damaged elements with polymer glue, but a long service life of the window is possible only after replacing the damaged profile or double-glazed window.

Often occurs due to the heavy weight of the sash or installation errors. This problem also appears on frequently used windows.

Usually this problem is solved by adjusting the fittings.

The reason may not be correct installation sealing rubber, lack of maintenance of the seal or its expiration.

Replacing the rubber and adjusting the fittings in this case will make the window warmer.

There are two reasons: either it is cheap or it is not used correctly.

In the first case, it is worth replacing, in the second, it is enough to adjust. It is recommended to start insulating old windows by replacing the fittings.

Insulation of plastic windows

Plastic windows are considered to be very reliable products, but they cannot always fully protect you and your home from adverse weather conditions. There are many reasons for this. One of them is the wear and tear of some window elements, for example, sealing rubber. The seal requires constant care and regular replacement at least once every 5 years. To avoid sagging of the sashes, you need to regularly adjust the fittings.

Insulation of aluminum windows

In the main aspects, insulation of plastic, aluminum and wooden windows similar. However, it is worth remembering that aluminum is a poor thermal insulator. That's why aluminum windows not recommended for residential use.

Aluminum systems are used for facade glazing of buildings, including residential ones. In this case, installing a second glazing circuit or replacing the sashes with plastic or wooden ones will help solve the problem with thermal insulation.

There are windows designed for cold glazing (Provedal). Such structures are mainly used for glazing balconies, loggias, terraces and verandas. Their insulation will not bring tangible benefits.

Insulation and repair of wooden windows using Swedish technology

If you value your old windows, but you are not satisfied with regular drafts, then we recommend that you pay attention to window insulation according to Swedish technology. In fact, this technology implies a complete reconstruction of windows.

The main stages of insulating windows using Swedish technology with your own hands

First, a check is made to ensure that the valves are operating correctly. If problems are identified at this stage, then later they resort to adjusting or replacing the fittings. Next, remove all the doors and moving elements. The paint and varnish coating is removed from the frames and sashes, all wood defects are eliminated and then painted. Seals are secured along the perimeter of the sashes. The final stage is the installation of fittings and sashes.

What to do if the windows cannot be repaired?

All problems with old windows can be solved by ordering new ones. In this case, you need to carefully consider both the choice of product configuration and the choice of the company performing the installation. The following diagram will help you choose new windows:

What affects the price of insulating windows in a house?

Prices for window insulation in Moscow vary widely. For example, replacing a double-glazed window or restoring windows using Swedish technology will cost much more than adjusting fittings or replacing sealing rubber.

When plastic windows came into our house instead of wooden ones, the room became more comfortable and warmer.

But this is only if the structure is installed correctly and the installation was carried out by professional craftsmen.

But what to do if over time the apartment becomes cold and drafts appear?

In this case, you will need to insulate the plastic windows.

Insulating windows for the winter

To prevent wind and frost from being felt indoors in cold weather, use the service of insulating windows for the winter. There are many ways. The choice depends on what malfunction is detected in plastic construction. Here are the main ones:

1 Adjustment of system elements
2 Replacing a worn sealing element
3 Setting the “winter-summer” mode
4 Replacing a double-glazed window (single-chamber to double-chamber)
5 Sealing with silicone compound or polyurethane foam
6 Window sill update
7 Alignment of sash geometry

Insulating a plastic window allows you to get rid of such troubles as the appearance of moisture on the surface of the glass unit, the destruction of slopes due to temperature changes, the formation of mold, and the penetration of drafts.

Experts, not without reason, believe that about 40% of heat escapes through our windows. However window insulation and additional insulation can increase the temperature in any room by 4-5 °C.

There is an opinion that installing new windows from PVC profile will allow you not to think about heat loss. However, high-quality insulation Wooden windows will keep your home environmentally friendly and save your budget.

In general, there is an enviable variety of different ways to insulate windows with your own hands. But absolutely all of them are associated with certain difficulties and inconveniences associated with the operation of windows in the future.

Our company carries out work on insulation of windows using Swedish technology with Euro-Strip insulation. All work is carried out with a guarantee. Entrust the insulation of your home's windows to the experienced hands of specialists company " Windows Service Plus» .

Prices for window insulation work

Our company provides a guarantee on all work for a period of 3 years.

High-quality insulation of windows using Swedish technology is carried out in stages, in compliance with all technological requirements.

The procedure and composition of work for insulating wooden windows:

1) Before starting insulation, it is advisable to wash the windows.

2) The first step is to check the sashes of wooden windows for the effectiveness of their closing, and also carefully check all the mechanisms for their functionality.

3) Only then can you safely remove the sashes from their hinges. Our craftsmen carry the sashes to the landing in order to maintain cleanliness in your home).

4) Already on landing careful adjustment of the sashes is carried out. To do this, excess layers are ground off old paint, preventing the sashes from fitting tightly to the window frame when opening and closing the sashes.

5) In order to put the insulation in its place, craftsmen create special grooves along the entire contour of the wooden window sashes using a milling cutter.

6) A high-quality Euro-Strip seal is rolled into the prepared grooves.

7) In addition, the window sashes are insulated between each other and inside the sashes. This seal will help prevent the penetration of dust and dirt.

8) Upon completion of the above work, the sashes are re-attached to the hinges, and the fittings are replaced. The customer can order replacement accessories in advance.

9) And at the end of the insulation work, a final check of the sashes of insulated wooden windows is carried out for opening and closing, as well as for the quality functioning of all mechanisms and installed fittings.

The determining factor for replacing old wooden windows with new ones, metal-plastic or PVC, is their ability to retain heat in a house or apartment. Naturally, when installing double-glazed windows, few people were interested in how they would behave in the future. Will the cold be allowed in, is it possible to insulate plastic windows if necessary, and is this necessary? If so, how to prepare windows for winter and the better way to ensure thermal insulation of windows and openings.

A plastic or metal-plastic window, like any composite structure, has weak points. They are the potential “gates” for heat leakage from the room.

Blowing from a plastic window - find and eliminate

Where can it blow from plastic windows?

To understand why it blows from a PVC window, you need to inspect the components, and for this you need to know constructive principle window unit devices.

The most common places for blowing:

window glazing bead (glass unit holder);
rubber seal;
window fittings(for example, blowing from under the hinges, into the handle);
perimeter window frame– junctions of slopes, window sills, walls.

How to determine where it is blowing from a plastic window?

The presence of a defect in one of the components of the window unit leads to blowing from plastic windows. There are three ways to determine the exact location of heat loss from metal-plastic windows:

tactile hand. To identify a gap, just run your palm over the surface of the window block;

lighter. The search procedure is similar to the previous one, but the light is more sensitive to drafts and can detect even the weakest blowing.

sheet of paper. A regular sheet of paper is pressed against the window (put into open window and is clamped by the complete closure of the sash), if you pull the corner of the sheet and it is easily pulled out, then the seal is not pressed enough (this may indicate that the old seal does not press well against the frame in this mode).

Why does it blow from plastic windows - reasons for heat loss

installation error. This is the most common reason due to ignorance or non-compliance the right technology installation of a plastic window. 15 years ago, this service was so in demand that everyone who had at least some idea about installing window units became installers. Naturally, few people installed PVC windows according to GOST;

window distortion due to shrinkage of the house. A pressing problem for residents of new buildings and wooden houses;

an attempt to save money. One of the weighty arguments in competition is always price, especially during an economic crisis. Price reductions often occurred at the expense of quality: saving on foam, on insulation, ignoring the need to protect the heat insulator, using low-quality components when assembling windows - all this over time led to the fact that the consumer is forced to change or additionally insulate PVC windows;

physical wear of window components, in particular sealing rubber bands, or weakening of the pressing force of the sashes;

violation of the operating rules for plastic windows, which include the need to wash the window seal and treat it with glycerin. This care prevents the seal from losing its elasticity and cracking.

What to do if it's blowing from a plastic window

Of course, eliminate the source of the draft. From a practical point of view there are two simple options– call a specialist to repair and adjust (expensive) windows or do it yourself (cheap).

The desire to seal all the cracks yourself using improvised means is nullified because: firstly, it is not aesthetically pleasing, and secondly, there are no guarantees.

When is it advisable to hire professionals:

The plastic window was recently installed. The installer company is responsible to the consumer for the reliable operation of the windows (if the warranty covers this period);

the window opening is located at a considerable height (at multi-storey building). It is better to entrust any high-altitude work to professionals (industrial mountaineering services). If the window is located on the second floor or higher, the work will be associated with increased risk;

if there is a manufacturing defect. For example, obvious manufacturing or installation defects that appeared during the warranty period;

if necessary, replace parts. It is better to install “original” fittings if it is necessary to replace individual elements of the window unit;

work is carried out in winter. Knowledge of installation technology and how to insulate plastic windows for the winter allows installers to complete the work quickly, without significantly cooling the living space.

However, often, the cost of hiring specialists is equal to the cost of installing a new window, and this fact makes it more profitable to do the insulation work yourself.

What you can do yourself:

internal insulation of the window opening;
insulation of the frame contour;
window sill insulation;
replacement of seals.

How to insulate plastic windows with your own hands

When to insulate windows for the winter

Repairs and insulation must be carried out before the onset of cold weather. This is due to the following requirements:

more comfortable working conditions;

material requirements. Some building materials For example, dry mixes and sealants can only be used in a certain temperature range. Otherwise, they lose their characteristics;

optimal humidity;

no draft;

the ability to simultaneously perform internal and external insulation;

reducing the risk of catching a cold among apartment residents.

How to insulate plastic windows at home

The choice of insulation depends on the location of the blower.

1. Insulating window openings for the winter

To insulate a window opening, you can use different materials and methods:

polyurethane foam. As the foam expands, it fills all the voids around the perimeter of the window opening, preventing air movement. Due to the fact that foam is 90% air, it is an ideal insulation material. However, the foam needs protection from ultraviolet radiation, high and low temperatures. This means that it is not advisable to use it by itself;

mineral wool. Excellent thermal insulation material for insulating window sills and internal slopes. Cotton wool has a more limited range of uses when insulating windows;

polystyrene foam/expanded polystyrene. Used for insulating slopes of plastic windows;

Note. Rigid insulation is used when the thickness of the installation seam is no more than 3 mm; in other cases, it is better to give preference to mineral wool.

silicone sealant. A reliable way to eliminate air leaks between plastic window elements;

dry mixtures for finishing slopes, used if necessary to insulate the window from the outside;

construction tape. Glues on top of the sealant or instead of it;

Advice. It is not recommended to use ordinary masking or window tape; after sticking it, unattractive marks remain on the plastic of the window frame that are difficult to remove without damaging the front covering.

2. Insulation of the window unit

seal;
construction tape;
sealant;
heat-saving film for windows (energy-saving);
mechanical methods insulation, for example, tightening (adjusting) fittings.

After the question of how to insulate has been resolved, we will deal with the question of how to insulate a double-glazed window, frame, plastic, aluminum profile etc.

How to insulate plastic windows from the outside

External window insulation is carried out in the following areas:

1. Insulation of slopes of plastic windows

The first step to promotion thermal insulation properties windows. No matter what insulation measures are taken in the house, until the slopes from the street are insulated, the cold will still flow inside. At the same time, external insulation allows you to shift the dew point, which will prevent the appearance of dampness and the development of fungus. Covering the cracks is a temporary measure, because... Over time, the layer of plaster will begin to crack and expose polyurethane foam, which will collapse under the influence of atmospheric phenomena. But as protection for insulation, plaster is an excellent solution.

How to insulate the slopes of plastic windows from the street

Work order:

preparation of material (rigid insulation);

cleaning slopes from dirt and protruding parts;

surface primer;

installation of insulation on glue solution or special adhesive foam. It is preferable to use foam because it eliminates wet work, has a minimum setting time, and holds the insulation sheet more securely;

sealing all cracks with glue;

installation of perforated corners;

installation of polymer mesh;

finishing with plaster.

Advice. When installing insulation, you need to make sure that it covers part of the window frame and completely covers the installation seam.

2. Insulation of plastic window sills

To insulate the ebbs, it is enough to foam all the cracks or place heat-insulating material in them. To avoid water getting on the thermal insulation material, it is installed on top metal strip window tide. The plank is installed at an angle (at least 5 degrees), its horizontal edge extends from the facade (by 20-30 mm), and the side edges are turned up. It is recommended to treat the area where the plank joins the surfaces with sealant.

Internal insulation of plastic windows

Insulation of windows from inside the room is carried out in the following areas:

1. Insulation of internal slopes of plastic windows

Internal slopes are less affected external factors, but they put forward more demands on the aesthetic component. Therefore, it is important to know how to insulate the slopes of plastic windows without losing the attractiveness of the window.

Work order:

treatment of cracks: removal of dirt, removal of old foam, falling parts, etc.;
applying a primer;
sealing cracks with foam;
removing excess foam after it dries;
installation of thermal insulation materials (foam or cotton wool);
installation of drywall;
finishing drywall with putty and paint.

2. Insulation of the window sill of plastic windows

The gaps between the wall and the window sill are one of the places of significant heat loss. Before deciding how to insulate the window sill of a plastic window, you need to determine its weak point, i.e. where is it blowing from? For example, blowing is possible between the plastic parts of the window and window sill. In this case, it is recommended to use a sealant.

Heat loss between the window sill and the wall is also possible. In this case, insulation is carried out before installing the window sill by laying a layer thermal insulation material. And also after its installation - by foaming the distance between the window sill and concrete wall or brickwork.

3. Insulation by adjusting the plastic window

Elimination of distortion of the PVC window sash

To reduce heat loss, you need to adjust the fittings (components) of the window unit.

Replacing the seal in plastic windows

Eliminating the blowing of plastic windows is possible by replacing rubber seal. You can change the seal yourself, everything is simple - just pull out the old seal and insert a new one into the groove (groove).

Which seal is better? Please note that there are black and black window insulation on the market. gray colors. The black seal is more plastic, but attractive light color, is due to various additives that reduce the cost of the window seal, and at the same time, worsen its properties (tightness of pressing).

Additional ways to insulate plastic windows

Washing windows. Paradoxically, cleaning the glass unit helps save heat. After all, dirty glass loses its ability to transmit sunlight, but continues to transmit rays in the infrared spectrum.

Thick curtains. Which also trap heat indoors.

Insulating windows with improvised means. This method is somewhat damaging appearance windows, but in critical cases, it can become quite a worthy alternative replacing a window unit. The following materials are used as insulation: foam rubber, soaked paper, window tape, strips of white fabric, etc.

Insulation of windows with heat-saving film. The energy-saving film is glued to the entire surface of the window (on the sashes). The main thing is to do the gluing correctly, without air bubbles or folds. The film reduces heat loss through glass by 75%.

Electric window heating. In this case, a heating cable is placed around the window, which heats the heating coil, or an oil radiator is installed on the window.

Electric heating of double-glazed windows. The most technologically advanced way is to install plastic windows with heated glass. The technology is applied at the window production stage. Includes installation on inside glass of special conductive film ( transparent film with conductive threads), which heats the glass from the inside.

An integrated approach. The most appropriate for insulating windows in an apartment or private house, since it allows you to eliminate all possible causes of heat leakage through metal-plastic or PVC windows.

Conclusion

Insulating windows often negatively affects ventilation in the room. Complete tightness is protection from the cold, but it also causes fogging of the glass, which leads to the destruction of slopes and the appearance of fungus. The problem is solved by periodically ventilating the room, micro-ventilation, installing forced ventilation, etc.

Metal-plastic windows are identical in design and functionality to their counterparts made of plastic. The main difference between metal-plastic products is a reinforced frame made of galvanized steel and large selection shapes and non-standard designs. They can be made in the shape of an arch or oval.

Both metal-plastic and PVC models have excellent heat, noise and insulation characteristics. Reinforced metal frame Windows made of metal-plastic, thanks to the additional weight, fit more tightly to the frame, ensuring tightness. Problems with the thermal insulation of PVC windows are associated with the need for additional energy saving in cold climates or with shortcomings in the design or installation of window products. Therefore, if you are looking for an answer to the question of how to insulate plastic windows in a house , You should familiarize yourself with the structure of the window structure.

Insulation of plastic windows: what you need to know

If problems arise during the warranty period, you must contact the company

As a rule, problems with the thermal insulation of plastic windows arise in the following cases:

Mistakes at the stage of choosing a window design. Often the consumer himself is responsible for them. When choosing a window and profile, it is necessary to take into account the climatic operating conditions, correctly approaching the assessment of the double-glazed window, profile, and fittings.
Quality of window construction. Discrepancy between the characteristics of the product declared by the seller and the actual indicators. In this case, the question is how to insulate fiberglass windows if it is blowing, on our own it will not be possible to solve. The entire product needs to be replaced. To avoid this problem, it is better to opt for time-tested manufacturers.
In some cases, thermal insulation deficiencies are caused by individual component failures. In this case, window replacement is not required. It is not recommended to solve such problems on your own. It is enough to contact a company that specializes in the installation and installation of window structures.
Problems associated with violations of the product installation technology: the use of low-quality sealants or seals during installation, insufficient surface treatment, incorrect measurements. It is advisable to prevent such problems even at the stage of window installation. If this was not done in time, some shortcomings can be corrected on your own.
Poor quality fittings, incorrect adjustment of fittings. In this case, you can consult with specialists on how to adjust metal-plastic windows yourself, or resort to the services of professionals.
In some cases, drafts and depressurization are associated with the destruction of polyurethane foam. This deficiency can be eliminated on your own. To do this, you need to know how to insulate plastic windows from the outside. .
The destruction of the insulation layer is caused by the absence or insufficient insulation of the external slopes and window sill. In this case, the polyurethane foam lags behind the wall and gaps form through which cold air freely enters the room. If you want to insulate the slopes of plastic windows from the street, you need to know how to replace the mounting layer.

When working on window insulation, it is important to pay special attention to the window sill. How to do this correctly, read here.

Often, insulating plastic windows may be associated with the need for additional energy saving in cold climates or emergency situations. Here you can take advice from professionals or resort to everyday experience. In both cases, you will need knowledge of the structure of a metal-plastic window.

Construction of a metal-plastic window

Frame - load-bearing structure products made of reinforced steel profile. The formation of drafts and freezing of the window depend on how tightly the frame is fixed in the opening.
Double-glazed window. Energy saving and indoor microclimate depend on its characteristics. The more chambers a glass unit contains, the higher the thermal insulation properties of the window. In the climatic conditions of Russia, the standard is the use of structures with two-chamber double-glazed windows with a gap between them of up to 18 mm. An air cushion of heated dry air between the chambers acts as thermal insulation. If you are looking for a way to insulate a plastic window with your own hands , treat it with a special anti-moisture compound. As a rule, sealants are used for these purposes. This will protect against dampness and freezing in winter.
Accessories. Should ensure smooth opening and closing of the window. If the fittings are chosen incorrectly, the doors will not close tightly. This leads to additional heat loss.
Glazing bead. Designed for fastening double-glazed windows to the profile. Insufficiently strong fit of the glass unit to the profile is one of the design flaws, which is the cause of constant heat loss. For tightness, the stamp must be rubberized.
Low tide and visor. Distortions during the installation of the tide contribute to the accumulation of moisture in hard-to-reach places, which leads to ice and contributes to the freezing of the window in winter.
Slopes and window sill. They are an important energy-saving part of the window structure. Insulating the slopes and window sill outside the window will help increase the period during which the polyurethane foam does not lose its insulating properties. This will save you from drafts in your house and apartment.
Seals. High-quality seals protect against moisture, drafts, and promote reliable thermal insulation. To ensure the tightness of window products, they must be installed at each fastening and joint point.

The right choice of window designs

When choosing a window, you should remember that the quality of thermal insulation and energy saving will depend on:

on the characteristics and properties of the glass unit;
from correct installation window structures;
availability of high-quality seals;
from fittings, all parts of which must be rubberized;
application of innovative technologies - special compositions for processing; frames and glass, sealants, know-how;
defects in parts and components that reduce the quality of the product;

Depending on the thickness of the glass and the number of chambers, double-glazed windows are:

Number of double-glazed windows in a metal-plastic window

With one camera. Such double-glazed windows consist of two glasses with a thickness of 4 to 6 mm and a gap between them.

Double-chamber is the most common type of double-glazed window. Includes three glasses and two gaps and has a reinforced air insulating layer.
Three-chamber with reinforced double-glazed windows have three gaps between four glasses with an air cushion of 45 mm.

Adjusting fittings

IN in a broad sense By fittings it is customary to understand the mechanism for opening and closing a window, the modes and parts that provide it. The main function of the fittings is reliable sealing. To prevent cold air and moisture from penetrating into the room, and to prevent the window from freezing, the structure must be completely sealed. Therefore, for energy saving of an apartment or private house, fittings are as important as a reliable double-glazed window.

The fittings must provide:

The quality of window fittings affects not only longevity, but also thermal conductivity

Smooth and complete opening and closing;
Fixing the window in various modes and positions;
Ventilation of the room with minimal heat loss;
Protection against unauthorized entry and hacking;
Removing the load from the hinges. This prevents the sashes from sagging, jamming and depressurization.

Rules for installing metal-plastic windows

Improper installation of window structures can lead to serious problems that cannot be eliminated without repeating the entire procedure. Therefore, compliance with the installation requirements and stages must be approached very carefully, starting with choosing the brand of polyurethane foam and sealant and taking measurements. If you decide to entrust this procedure to professionals, then first you need to make sure that the entire procedure will be carried out in accordance with GOST. Compliance with GOST is a guarantor of the quality of work and the effective functioning of the product. The installation and installation of plastic windows is regulated by the main 2002. If the installation will be carried out by the same company where you purchased the product, it will be useful to find out the GOST compliance of the product itself. Requirements for thermal insulation of plastic windows have been established.1 Heat transfer and SNiP Thermal protection buildings.

In order to ensure the quality of the work performed, it is necessary to control the implementation of the following operations:

Window installation using high-quality sealants

preparation of the window opening: thorough cleaning of the surface, alignment of the horizontal level.
Gaps between frame and mounting surface. In accordance with the requirements, the gaps should not exceed 5 cm. It is also better not to leave them too small. In this case, it will not be possible to evenly distribute the foam along the entire length to the depth of the gap, which in the future can lead to the formation of drafts.
The quality of the assembly seam, the uniformity and density of its application. Polyurethane foam should be applied in stages at intervals of three layers.
The quality of the sealants and polyurethane foam used.
Installation additional elements insulation: external slopes.

Methods for insulating plastic windows

If you have come to the conclusion that your window needs additional insulation, you can resort to the following simple methods.

For a selection of the most effective and proven methods of insulating windows for the winter, see this link

The procedure is carried out in the following sequence:

For a warm window, correct installation of the window slopes is important.

First, remove the layer of old polyurethane foam in the resulting gaps;
We apply a material to its surface to hold the materials together; you can simply spray the gap with water;
Next, we form a new layer using sealant or polyurethane foam;
We seal the work area with construction tape for a few minutes;
After this, you can install new insulated slopes.

In specialized stores, ready-made insulated slopes will save a lot of time. The material used is extruded polystyrene foam. The energy efficiency of expanded polystyrene is 2-3 times higher than that of polystyrene foam.

Polystyrene foam as a filling material is suitable for insulating a window sill. The window sill is removed, a layer of foam is laid, the cracks are sealed with polyurethane foam and the window sill is installed in place.

How to insulate metal-plastic windows yourself

Metal-plastic windows in our country began to be actively installed only about 20 years ago, although in Europe they were appreciated much earlier.

A little history

Correctly, the material from which such windows are made is called polyvinyl chloride (PVC). It was invented by the German chemist Regnald in 1835, but for almost a hundred years the discovery had no practical use.

Only in the last century did Germany master industrial production PVC – its founder is considered to be the German scientist Fritz Klatte, who received the first patent for this in 1913, and PVC began to be produced en masse in 1931.

Later, the German designer Heinz Pasche patented plastic window frames. In the 60s, the technology was improved, and a real “window boom” occurred in Europe. It has also reached Russia and the CIS countries, albeit with a great delay, and currently the demand for metal-plastic windows is only growing.

Consumers value PVC frames for their durability (which is no worse than that of wood), environmental friendliness, weather resistance, effective heat and sound insulation, ease of maintenance, and also for the fact that windows of any shape can be made from PVC profiles.

Disadvantages of metal-plastic windows and ways to eliminate them

Even during installation, metal-plastic windows are insulated with special rubber insulation and sealants. For the first year or two this is quite enough, but after a certain time the need for additional insulation arises.

There are several reasons why metal-plastic windows lose their tightness over time.

Seal defects

The sealing rubber profiles sooner or later dry out and become smaller, and therefore air begins to leak in the place where the window sash is adjacent to the frame.

If the reason for the drafts moving around the apartment is only a worn-out rubber seal, then it needs to be replaced.

First of all, we remove the glazing beads (starting from the side linings), dismantle the double-glazed window, remove the old seal, cut off the new sealing tape a little longer (3-5 cm) than the length of the old one, carefully lay the new seal and put the double-glazed window in place along with the linings and beadings.

Some people try to get by by lubricating the dried rubber with silicone grease, but this method only helps for a few hours.

Deformation of window openings

Shrinkage of the walls of the house occurs, and along with this - deformation window openings. If you live in an old house, this is unlikely to happen to you. But in newly built houses this happens very often. What to do? Buy a new seal and fill the resulting gaps with it.

Problems with fittings

The cause of heat leakage through metal-plastic windows can be the weakening of the eccentrics of the closing fittings. The eccentrics are located at the end of the window sash. If you have a standard sash, they can be found on the side where the handle is placed.

If the sash is tilting, then the eccentrics are located on the vertical ends on both sides. In this case, the insulation of plastic windows begins with adjustment using fittings, for which you will need a four-millimeter hex wrench.

They need to adjust the clamping eccentrics. To do this, we slowly turn them to a horizontal position, checking after each step how easily the sash closes.

It is also possible that builders may make mistakes - for example, incorrectly made slopes or unattended gaps between the window and the sill, through which cold air from the street enters the house.

In any case, it is best to identify cracks in winter, and carry out insulation in warm, calm and dry weather.

Budget insulation options

You should think about insulating PVC windows at the stage of their installation, but if for some reason this does not happen, there are several quite budget options correct the situation “after the fact.”

Warm blanket or thick cloth

If you are limited on funds, you can resort to one of the cheapest options - closing the window with any material that retains heat.

Windows with wooden frames often hung with woolen blankets: several nails were driven into the upper part of the frame, and accordingly, holes were made in the blanket for these nails (or the blanket was simply nailed down).

This option is not suitable for metal-plastic windows, since you risk damaging the frame once and for all. But you can attach thick fabric to tape: it will blow less. The only negative is that the fabric will block the light from the street.

Polyethylene film

Another cheap option insulation of double-glazed windows - gluing them plastic film. It is transparent, so there will be no darkness in your home. But the film will add heat. In addition, it is easy to install and dismantle.

There is a film specifically designed for metal-plastic windows - heat-saving PVI. Its surface is covered with a special metal coating, which reflects infrared rays and traps heat indoors.

Insulation of blinds

An interesting way is to insulate not the window itself, but the blinds. To do this, strips of woolen fabric are glued to the parts of the blinds. The process is labor-intensive, but it turns out cheap and high quality.

Heated windows

Most original method– install an electric heating system on the windows, like in a car. On sale you can find various heaters that are installed on window sills, and spirals attached to the glass with glue. The house will not only be warm, but even hot. Only this method can hardly be called budgetary.

Materials

Currently, there are many materials that can be used to insulate PVC windows.

Polyurethane foam

Polyurethane foam is one of the most affordable and frequently used insulation materials, but it quickly loses its properties from temperature changes, exposure ultraviolet radiation and even plain air. Therefore, in this case it is necessary to purchase special polyurethane foam for installing windows.

"Warm" mixtures

“Warm” mixtures are best used for exterior work - when waterproofing of the plaster mortar is needed, a moisture-proof primer and painting are used.

Sealants

Even a housewife can handle sealants when it comes to sealing small gaps between window profile and window sill, slopes and ebbs. The main thing is not to forget to wash and degrease the window sill and slopes before doing this.

Mineral wool

Fire-resistant, environmentally friendly, effective insulation.

Expanded polystyrene foam

Affordable. Not susceptible to microorganisms. Has low water absorption. Vaporproof. Most often used to eliminate cracks in window slopes.

Better in strength, thermal insulation characteristics and water absorption than polystyrene foam.

Insulation of external slopes and window sills

Heat leaks often occur due to the absence or poorly made external slopes, as well as due to poorly fitted, uninsulated window sills.

External slopes

If external slopes are not installed, then over time the polyurethane foam is exposed to external environment deforms and loses its properties. In such cases it is necessary:

carefully remove old mounting foam;
spray the gap with water for better adhesion of materials;
fill the gap with new mounting foam or sealant (in this case, after 5-7 minutes the sealant should be sealed with construction tape);
install external slopes insulated with mineral wool, polystyrene foam or extruded polystyrene foam (EPS).

Window sills

The same materials (mineral wool, polystyrene foam or EPS) are also used to insulate window sills. To do this, the window sill is removed, a layer of insulation is laid, and the window sill is returned to its place.

Before starting work, all surfaces that may be damaged are sealed with construction tape (but in no case with packaging!) tape.

Why insulate plastic windows? This reasonable question probably arises among all owners of modern hermetic structures, because the manufacturers sold us a perfect product with ideal thermal insulation. Installation errors, improper operation, shrinkage of the house and time can play a cruel joke on even the highest quality windows. Don’t rush to change the entire structure - you can try to insulate plastic windows yourself. It's easy and doesn't take long. We understand the weak points of modern windows and learn how to eliminate them.

No. 1. Why do plastic windows need insulation?

In the first few years, well-made and installed plastic windows will certainly be a reliable barrier to cold air, drafts and noise. Over the years, of course, problems can arise, and often the user himself is to blame. If installation is done incorrectly, various defects can make themselves felt in the first season.

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 new buildings;
wear of rubber insulation. Responsible manufacturers and installers inform the user about the rules for caring for the rubber seal, but few follow the rules and regularly inspect the condition of this structural element. Lack of proper care leads to an accelerated process of thinning and drying of the rubber, the appearance of microcracks in its structure, the result is a decrease in the tightness of 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, which is why it is so important to be able to choose the right plastic window and immediately decide on a suitable double-glazed window.

No. 2. We identify weak points

To spend effective insulation plastic windows, you must first figure out where the seal is broken. The only thing you can immediately remove from the list of suspects is the frame: multi-chamber plastic is a good heat insulator, it does not dry out, unlike wood.

Cold air can penetrate through the following structural elements:

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

Identify leaking elements windows It’s simple - just run your palm along and across the entire structure, and you will feel that there is a decent amount of air in some places. Some people recommend using a lighter for this purpose. If you light a flame and pass it around the perimeter of the window, maintaining a safe distance, it will tilt in those places where there is even a small draft. Be extremely careful with this method!

As a rule, work on insulating a plastic window can be done with your own hands. The exception is when it is necessary to insulate the slopes from the outside, and the apartment is located above the second floor. You need to be prepared that comprehensive insulation may be needed if several leak zones are found warm air, but first things first.

No. 3. Debugging the clamping mechanism

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

Adjustment of the clamping mechanism can be done using special eccentrics located around the perimeter of the sashes. To ensure a tighter fit of the sash, the eccentric must be turned clockwise using a 4 mm hex key. Focus on the serif located on each such element. When it is directed towards the street, the pressure is weakened; when it is directed towards the seal, it is strengthened. The video shows everything well.

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

Things are even simpler with glazing bead. It is enough to pry off the old, loose 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 your windows.

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

No. 4. Replacing the seal

Ideally, a rubber seal can last quite a long time, but for this to happen, certain conditions must be met. According to the operating rules for 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 the cold breeze from the street. The problem may be in the seal, which is located under the glass, or in the one that is located along the contour of the sash. Replacing the seal in a plastic window is not so difficult as it is responsible. If you doubt your skills, it is better to call a specialist.

Procedure for replacing the window seal:

May need replacement seal, which is located along the contour of the sash. In this case, it is better to remove the sash. First, the decorative overlays are removed from the hinges, and then the pin is pulled out of the hinge using a mounting handle or screwdriver. All that remains is 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 secure the beginning and end of the sealing tape with glue. All! All that remains is to hang the sash back: you can install the pin with your bare hands, and then return the decorative trim to its place. The video shows and describes everything very well.

No. 5. Window sill insulation

The installation of a plastic window is often associated with significant damage, which is especially significant in the area between the wall and the window sill. Some installers fill the cracks with cement and construction waste. No comments here. It is better, of course, when the space under the window sill is filled with polyurethane foam, but this option is not ideal. Over time, the foam can shrink or even dry out, forming decent gaps 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 new one. Keep in mind that it tends to expand as it hardens. After complete hardening, the excess is cut off; some builders recommend additionally filling small cracks silicone sealant. This is followed by plastering work and application of decorative coating.

If possible, the window sill area can be additionally insulated from the outside. Polyurethane foam is also used for this, but sometimes polystyrene foam is also used. Everything is plastered on top using a mesh and finished off.

No. 6. Insulation of slopes

Today, often when installing plastic windows, slopes are additionally installed, smooth, beautiful, made of dense plastic. It often happens that between the decorative strip and the wall there is big crack, 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 unnecessary parts of polyurethane foam;
if the surface is very uneven, you can plaster it;
treating the slope with a primer, you can use antibacterial compounds to prevent the development of mold;
A fragment corresponding to the slope is cut out of foam plastic. To make it stick better to the surface, with reverse side it may be slightly scratched. All that remains is to apply assembly glue and press firmly to the surface of the slope; to guarantee, you can install several dowels;
All that remains is to mount the corner, putty the surface and secure the casing.

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

The methods described above 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 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;
electric window heating;
wool blinds and curtains.

Heat-saving film- thin transparent material, which does not change the optical properties of glass, but is reflective 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 several times higher than any film, but if a regular double-glazed window is installed in the existing windows, then additional insulation will not be superfluous.

You can easily do the installation of the film yourself:

the surface of the glass and frame are thoroughly cleaned;
double-sided tape is glued around the perimeter of the box;
The required fragment is cut 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 with warm air from a hairdryer. It is necessary to act slowly so that the result is accurate and there are no distortions or bubbles. Correctly applied film is almost invisible.

Electric 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 by an electric heating coil built into the glass.

Well, and finally, the most banal, uncomplicated and universal methods make the window a little warmer. This thick curtains and wool blinds. The latter can be done by wrapping ordinary blinds with woolen fabric.

It is better to carry out work on insulating plastic windows on a warm, dry day, since many materials can no longer be worked at temperatures below +5...+10 0 C, and you can let the cold into the apartment. To face the problem of insulation as soon as possible modern window, it is worth taking the choice of a window manufacturer as seriously as possible and paying attention to selecting the optimal technical characteristics, focusing on the climate of the region. It is also important to choose a responsible installer and remember to properly maintain the window.

How and how to insulate plastic windows for the winter with your own hands

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 temperatures are uncomfortable, significantly reduce the quality of life, and not only the comfort of home is lost. Along with the heat, money spent on utilities or heating natural resources also leaves the home.

That's why practical owners think in a timely manner about how to insulate double-glazed windows in plastic window designs. This will reduce housing maintenance costs, will make life more comfortable.

Modern plastic windows, due to their materials and design features, are significantly superior to wooden ones in terms of thermal insulation and sound insulation. However, for a number of reasons these properties may be lost:

installation errors;
malfunction of fittings and fasteners;
aging of the seal;
improper insulation or destruction of the insulation material of the window sill, slopes, construction foam in assembly seams;
lack of season-appropriate pressure adjustment;
deformation due to shrinkage of the building.

Another reason may be the low quality of materials used in the manufacture and installation of plastic windows.

Identifying problem areas

If you have problems with the tightness of plastic windows, you should find hot air leaks. First of all, it is necessary to exclude the presence of holes, cracks, and loose fit of the valves. Simple methods can be used:

using a lit candle or a simple lighter - the flame will sensitively react by deflecting to the presence of the slightest draft;
tactile - just run your palm along the perimeter of the opening and weaves, don’t forget the wall under the window sill: a stream of cold air will let you know about the presence of a through hole;
open the flap slightly, insert a sheet of paper and close it again, now try to pull out the sheet, if possible - there is a problem with the tightness of the fit.

The problem may be hidden by slope panels or a window sill: perhaps the insulation material has deteriorated, and a void arose, the heat-saving properties of the window were lost. Before dismantling structural elements plastic windows, conduct an examination:

Tap on the surface of the panel: if there are voids there, they will respond to tapping with a louder sound.
Carefully check the tightness of the connection of the structural elements of the window; if you find any cracks, glue them.
Make sure there is no deformation of the frame.
Pay attention to cases of condensation, frost, and frost.

Do-it-yourself insulation

Methods for solving a problem are chosen depending on its location, the cause of its occurrence and the materials used.

Insulation of slopes and window sills

Slopes on the street side are insulated before installation of the window block begins, because some connecting seams will then be inaccessible. But if a violation of thermal insulation occurs, insulation window slopes the outside should be left to specialists, especially if the apartment is on the second floor or higher.

The slope panel is dismantled, the layer of plaster is removed, the surface is cleaned and primed.

a new layer is added to the polyurethane foam and the voids are filled;
sheet insulation (mineral wool, polystyrene foam) is changed;
The cracks and seams are taped.

After this, the decorative panel is mounted or plastered and painted with thixotropic paint.

How to insulate the slopes of plastic windows inside? To do this, proceed in a similar way. But first, it makes sense to dismantle only the decorative corners framing the slopes.

The flaw may be easy to fix by using mounting gun and foam, simply filling the voids.

If more complex work lies ahead, they begin by dismantling the cladding. If the damage is minor, it is enough to fill the voids with heat-insulating material.

Severely damaged thermal insulation sheets are removed and new ones are strengthened. This can be done using construction foam, which will also serve as additional insulation. Before installing new material, all surfaces must be cleaned and primed (preferably with deep penetration), the seams are treated with sealant or glued.

If only foam serves as a thermal insulation material, the joints of the foam with plastic frame also treated with sealant. This will prevent moisture accumulation, rotting and unsightly streaks.

After repairing the insulating layer, facing panels are installed. This material not only serves decorative finishing, but also creates additional thermal protection.

Don't forget to check the "protective" qualities of the window sill. Some tips on how to insulate the window sill of a plastic window:

determine where it is coming through (as indicated above);
if the cold is pulling from the seam between the window sill and the frame, treat it with sealant;
if the problem area is between the window sill and the wall, seal this space with polyurethane foam.

Replacing seals

Over the years of operation of plastic windows, an elastic rubber seal gets old, loses elasticity, and with it heat-shielding properties. Replacing insulation in PVC windows quite within the capabilities of the homeowner:

Prepare a new seal, measure a few centimeters longer than the perimeter of the frame.
Pry the old rubber cord and pull, it will easily come out of the recess.
Thoroughly clean the groove from dirt and dust.
Insert and press down the new seal (if necessary, add a drop of glue), cut off the excess.

Seals sold in construction stores, differ in color, but are approximately the same in quality of material.

Setting the pressure

Air is often leaked through opening window sashes due to poor pressure adjustment. The trouble is eliminated using a 4 mm hexagon.

The control device is located at the end of the window frame. By turning the eccentric with a key, monitor the position of the signal mark. In winter it should be directed indoors, in winter - towards the street, in the off-season it should occupy an intermediate position.

Additional sealing of plastic windows is achieved adjusting the position of the sash on the frame. The mechanism is hidden in the hinges. By loosening or tightening the adjusting screw, the optimal position of the sash is adjusted.

Choosing material

Let's look at how to insulate a plastic window by choosing optimal view material. The determining factors when choosing how to insulate plastic windows are affordability, ease of use, durability, and safety.

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

Basalt (stone, mineral) wool:

excellent thermal insulation properties, suitable for indoor and external insulation plastic windows;
elastic, durable material;
fireproof and environmentally friendly.

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

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

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

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

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 the top layer from the adhesive tape and 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.

Main mistakes

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

dismantle, change structural elements, components and fittings during the manufacturer's warranty period and installer; V 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.

Useful video: insulating a plastic window using a special tape

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

How to insulate plastic windows for the winter - insulation technology from the outside and inside

A plastic or metal-plastic window, like any composite structure, has weak points. They are the potential “gates” for heat leakage from the room.

Blowing from a plastic window - find and eliminate

Where can it blow from plastic windows?

To understand why it blows from a PVC window, you need to inspect the components, and for this you need to know the design principle of the window unit.

The structure of a window unit - the main elements Construction of a plastic window and door - list of elements

The most common places for blowing:

window glazing bead (glass unit holder);
rubber seal;
window fittings (for example, blowing from under the hinges, into the handle);
the perimeter of the window frame - the junction of the slopes, window sill, walls.

How to determine where it is blowing from a plastic window?

tactile hand. To identify a gap, just run your palm over the surface of the window block;

lighter. The search procedure is similar to the previous one, but the light is more sensitive to drafts and can detect even the weakest blowing.

sheet of paper. A regular sheet of paper is pressed against the window (put into the open window and clamped by completely closing the sash), if you pull the corner of the sheet and it pulls out easily, then the seal is not pressed enough (this may indicate that the window is working in summer mode, the old seal does not press well against the frame in this mode).

Why does it blow from plastic windows - reasons for heat loss

installation error. This is the most common reason associated with ignorance or non-compliance with the correct technology for installing a plastic window. 15 years ago, this service was so in demand that everyone who had at least some idea about installing window units became installers. Naturally, few people installed PVC windows according to GOST;

window distortion due to shrinkage of the house. A pressing problem for residents of new buildings and wooden houses;

an attempt to save money. One of the weighty arguments in competition is always price, especially during an economic crisis. Price reductions often occurred at the expense of quality: saving on foam, on insulation, ignoring the need to protect the heat insulator, using low-quality components when assembling windows - all this over time led to the fact that the consumer is forced to change or additionally insulate PVC windows;

physical wear of window components, in particular sealing rubber bands, or weakening of the pressing force of the sashes;

violation of the operating rules for plastic windows, which include the need to wash the window seal and treat it with glycerin. This care prevents the seal from losing its elasticity and cracking.

What to do if it's blowing from a plastic window

Of course, eliminate the source of the draft. From a practical point of view, there are two simple options - call a specialist to repair and adjust (expensive) windows or do it yourself (cheap).

The desire to seal all the cracks yourself using improvised means is nullified because: firstly, it is not aesthetically pleasing, and secondly, there are no guarantees.

When is it advisable to hire professionals:

The plastic window was recently installed. The installer company is responsible to the consumer for the reliable operation of the windows (if the warranty covers this period);

the window opening is located at a considerable height (in a multi-story building). It is better to entrust any high-altitude work to professionals (industrial mountaineering services). If the window is located on the second floor or higher, the work will be associated with increased risk;

if there is a manufacturing defect. For example, obvious manufacturing or installation defects that appeared during the warranty period;

if necessary, replace parts. It is better to install “original” fittings if it is necessary to replace individual elements of the window unit;

work is carried out in winter. Knowledge of installation technology and how to insulate plastic windows for the winter allows installers to complete the work quickly, without significantly cooling the living space.

However, often, the cost of hiring specialists is equal to the cost of installing a new window, and this fact makes it more profitable to do the insulation work yourself.

What you can do yourself:

internal insulation of the window opening;
insulation of the frame contour;
window sill insulation;
replacement of seals.

How to insulate plastic windows with your own hands

When to insulate windows for the winter

Repairs and insulation must be carried out before the onset of cold weather. This is due to the following requirements:

more comfortable working conditions;

material requirements. Some building materials, such as dry mixes and sealants, can only be used in a certain temperature range. Otherwise, they lose their characteristics;

optimal humidity;

no draft;

the ability to simultaneously perform internal and external insulation;

reducing the risk of catching a cold among apartment residents.

How to insulate plastic windows at home

The choice of insulation depends on the location of the blower.

1. Insulating window openings for the winter

To insulate the window opening you can use different materials and ways:

polyurethane foam. As the foam expands, it fills all the voids around the perimeter of the window opening, preventing air movement. Due to the fact that foam is 90% air, it is an ideal insulation material. However, the foam needs protection from ultraviolet radiation, high and low temperatures. This means that it is not advisable to use it by itself;

mineral wool. An excellent thermal insulation material for insulating window sills and internal slopes. Cotton wool has a more limited range of uses when insulating windows;

polystyrene foam/expanded polystyrene. Used for insulating slopes of plastic windows;

silicone sealant. A reliable way to eliminate air leaks between plastic window elements;

dry mixtures for finishing slopes, used if necessary to insulate the window from the outside;

construction tape. Glues on top of the sealant or instead of it;

2. Insulation of the window unit

seal;
construction tape;
sealant;
heat-saving film for windows (energy-saving);
mechanical methods of insulation, for example, tightening (adjusting) fittings.

After the question of how to insulate has been resolved, we will deal with the question of how to insulate a double-glazed window, frame, plastic, aluminum profile, etc.

How to insulate plastic windows from the outside

External window insulation is carried out in the following areas:

1. Insulation of slopes of plastic windows

The first step to increasing the thermal insulation properties of the window. No matter what insulation measures are taken in the house, until the slopes from the street are insulated, the cold will still flow inside. At the same time, external insulation allows you to shift the dew point, which will prevent the appearance of dampness and the development of fungus. Covering the cracks is a temporary measure, because... Over time, the layer of plaster will begin to crack and expose the mounting foam, which will collapse under the influence of atmospheric conditions. But as protection for insulation, plaster is an excellent solution.

How to insulate the slopes of plastic windows from the street

Work order:

preparation of material (rigid insulation);

cleaning slopes from dirt and protruding parts;

surface primer;

installation of insulation on an adhesive solution or special adhesive foam. It is preferable to use foam because it eliminates wet work, has a minimum setting time, and holds the insulation sheet more securely;

sealing all cracks with glue;

installation of perforated corners;

installation of polymer mesh;

finishing with plaster.

2. Insulation of plastic window sills

To insulate the ebbs, it is enough to foam all the cracks or place heat-insulating material in them. To prevent water from getting on the heat-insulating material, a metal strip of window sill is installed on top. The plank is installed at an angle (at least 5 degrees), its horizontal edge extends from the facade (by 20-30 mm), and the side edges are turned up. It is recommended to treat the area where the plank joins the surfaces with sealant.

Internal insulation of plastic windows

Insulation of windows from inside the room is carried out in the following areas:

1. Insulation of internal slopes of plastic windows

Internal slopes are less susceptible to the influence of external factors, but put forward more demands on the aesthetic component. Therefore, it is important to know how to insulate the slopes of plastic windows without losing the attractiveness of the window.

treatment of cracks: removal of dirt, removal of old foam, falling parts, etc.;
applying a primer;
sealing cracks with foam;
removing excess foam after it dries;
installation of thermal insulation materials (foam or cotton wool);
installation of drywall;
finishing drywall with putty and paint.

2. Insulation of the window sill of plastic windows

Heat loss between the window sill and the wall is also possible. In this case, insulation is carried out before installing the window sill by laying a layer of heat-insulating material. And also after its installation - by foaming the distance between the window sill and the concrete wall or brickwork.

3. Insulation by adjusting the plastic window

Elimination of distortion of the PVC window sash

To reduce heat loss, you need to adjust the fittings (components) of the window unit.

Replacing the seal in plastic windows

Elimination of blowing of plastic windows is possible by replacing the rubber seal. You can change the seal yourself, everything is simple - just pull out the old seal and insert a new one into the groove (groove).

Which seal is better? Please note that there are window insulation in black and gray colors on the market. The black seal is more flexible, but the attractive light color is due to various additives that reduce the cost of the window seal and at the same time worsen its properties (pressure tightness).

Washing windows. Paradoxically, cleaning the glass unit helps save heat. After all, dirty glass loses its ability to transmit sunlight, but continues to transmit rays in the infrared spectrum.
Thick curtains. Which also trap heat indoors.
Insulating windows with improvised means. This method somewhat spoils the appearance of the window, but in critical cases it can be a very worthy alternative to replacing the window unit. The following materials are used as insulation: foam rubber, soaked paper, window tape, strips of white fabric, etc.
Insulation of windows with heat-saving film. The energy-saving film is glued to the entire surface of the window (on the sashes). The main thing is to do the gluing correctly, without air bubbles or folds. The film reduces heat loss through glass by 75%.
Electric window heating. In this case, a heating cable is placed around the window, which heats the heating coil, or an oil radiator is installed on the window.
Electric heating of double-glazed windows. The most technologically advanced way is to install plastic windows with heated glass. The technology is applied at the window production stage. It involves installing a special conductive film (transparent film with conductive threads) on the inside of the glass, which heats the glass from the inside.
An integrated approach. The most appropriate for insulating windows in an apartment or private house, since it allows you to eliminate all possible reasons heat leakage through metal-plastic or PVC windows.

Conclusion

Insulating windows often negatively affects ventilation in the room. Complete tightness is protection from the cold, but it also causes fogging of the glass, which leads to the destruction of slopes and the appearance of fungus. The problem is solved by periodic ventilation of the room, micro-ventilation, installation forced ventilation etc.
