How to insulate plastic windows. Insulation of plastic windows. Window insulation using Swedish technology

Metallo plastic windows, made from polyvinyl chloride, have thoroughly entered our life, gradually replacing window structures from wood. The main advantage of plastic structures - elevated level thermal insulation to ensure a comfortable environment. With poor-quality installation, outdoor air cools the living space and the question arises of how to insulate plastic windows. The work is easy to do on your own. This will save money. It is important to understand the design features, to determine the source of cold.

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

Plastic double-glazed windows are actively advertised by manufacturers who convince customers of their high thermal insulation properties. The increased interest in plastic structures is forcing specialized firms to carry out their installation using accelerated methods using only foam. installation composition. Foam, even abundantly filled, cannot provide effective protection rooms from cold penetration.

plastic or plastic window, like any composite structure, has weaknesses

As a result, problematic situations arise, to get out of which it is necessary to:

• apply to the service center specialists. This is associated with additional costs and certain inconveniences. After all, you need to adjust your schedule to the time the service representative arrives;
• carry out work on thermal insulation on their own. Having studied the device of the metal-plastic structure, as well as determining the cause of the influx of cold air, you can fix the problem yourself.

Let's take a look at the second option. Do not delay the solution of insulation problems with the following negative points:

• detection of heat loss;
• the presence of a constant draft.

IN winter time it is problematic to carry out thermal insulation measures, since significant cooling of the room is possible and many sealing compounds need a special temperature regime. Work on the thermal insulation of plastic frames is best done in spring summer period. It is advisable to choose a day for work with a comfortable temperature and, if possible, without wind.

You should first study the design, which includes the following elements:

• metal-plastic profile, which is the power element of the frame;
• elastic seals that seal the junction area of ​​​​the double-glazed window;
• a glass package consisting of several hermetically assembled glasses;
• fittings designed to adjust the position and opening of the valves;
• window sill and slopes located in the lower and side parts of the window opening.

Lack of tightness, the occurrence of component failure causes heat loss. After completing the insulation window frames it is possible to further reduce the noise level, ensure the dust tightness of the opening, and also improve its aesthetic perception.

The presence of a defect in one of the components of the window unit leads to the fact that the plastic windows blow

Insulation of plastic windows - problem areas

Eliminating defects in a metal-plastic structure requires a professional approach and compliance with safety requirements. Insulation of slopes of plastic windows from the outside can be done independently only if the windows are located at the level of the first or second floor. In other cases, it is necessary to use the services of specialists who can perform work at height.

For independent performance of work, it is necessary to carefully study the technology of thermal insulation, to know the problem areas:

• circuit window construction along the perimeter of the frame;
• slopes from the inside and outside of the opening;
• window sill located inside the room.

The most problematic area through which heat losses occur are slopes. Cooling of the room through double-glazed windows is possible only in case of depressurization. It is important to correctly diagnose the cause of the intake of cold air and be able to eliminate the breakdown.

How to identify an air leak

Definition problem areas, through which cooled air enters, it is better to perform on a windy and cool day. These are the most favorable conditions for identifying the problem area.

To identify the gap, it is enough to run your palm over the surface of the window block

You need to pay attention to the following points:

• the state of the lining located around the perimeter of the glass package fastening;
• the integrity of the rubber seal, which ensures a snug fit of the double-glazed window to the frame;
• the absence of backlash and the functioning of the fittings, which ensures the rotation and fixation of the frames;
• tightness of the opening along the contour of the fiberglass window at the level of the window sill and slopes.

To find the gap, it is necessary to visually assess the condition of the assembly seam. You should look for the source of the draft in the following ways:

• lit lighter. By the state of the flame, when moving the lighter along the perimeter of the frame, you can easily find where cold air enters the room;
• the palm of your hand. Substituting the palm in the seam area, and slowly moving it around the perimeter, it is easy to identify problem areas where the installation was done in bad faith.

How to insulate plastic windows with your own hands

Having decided which area needs to be repaired, you can independently insulate PVC windows. Let us dwell in detail on the heaters used, as well as methods of thermal insulation of problem areas.

The choice of insulation depends on the place of blowing

How to insulate plastic windows for the winter - selection of a heat insulator

In specialized stores, a wide range of various building materials for thermal insulation is offered. As a heater use:

• mounting foam. It is the most commonly used heat insulator. It is easy to apply, increasing in volume. However, it is destroyed under the influence of temperature fluctuations and ultraviolet rays;
• cotton wool on a mineral basis. It is a safe and fire-resistant heat insulator, with which it is convenient to insulate the window sill. Mineral wool is hygroscopic, needs protection from moisture;
• silicone sealant. An inexpensive and proven tool that reliably seals small cracks around the perimeter of the window structure. Does not allow dust to enter the room;
• thermal film for windows. transparent material easy to self-attach to the surface. It prevents heat loss through the package glass;
• sheet foam. Is different affordable price, easy to cut, used to seal cracks and eliminate gaps located along the contour of the window frame;
• construction tape. Used in conjunction with various types sealing compositions, is attached after hardening to a frozen surface. Increases the effectiveness of thermal insulation.

After studying the features of the materials and consulting with a specialist, you can decide on their use for thermal insulation of windows.

Construction tape. Adhesive over or in place of sealant

Insulation of slopes of plastic windows

In the area of ​​slopes, significant heat losses can occur in the absence of effective thermal insulation. You can use mounting foam, basalt slabs, as well as other heaters available.

Consider how to insulate the slopes of plastic windows inside. The procedure for thermal insulation of slopes:

1. Ensure that the slope surfaces are clean.
2. Attach the heater.
3. Seal the gaps with mounting foam.
4. Apply a layer of protective plaster.
5. Seal the gaps with sealant.
6. Perform the finishing touches.

Thermal insulation of the side parts of the window opening from the outside is carried out in a similar way using moisture-resistant heat insulators.

Adjusting the position of the flaps

As a result of the gradual shrinkage of the building, which is typical for new buildings, there is a slight distortion of the valves. This negatively affects the thermal insulation properties of the window structure.

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

When performing adjustment work, using a special key, the eccentrics located on the following structural elements are rotated:

• top loop;
• lower hinge;
• locking mechanism.

By gradually turning the eccentric with a key, it is possible to ensure a tight fit and reliable fixation of the frames.

We change the insulation for plastic windows

To replace the insulation, it is necessary to remove the layer of plaster and seal the cracks with cement mortar.

Perhaps the main reason for installing plastic windows is their ability to retain heat well in the room. However, for various reasons (improper installation, long service life, etc.), this property may disappear. In the summer, this is not so scary, but with the onset of cold weather, poor thermal insulation can bring big trouble. In order to correct this situation, you can carry out the insulation of plastic windows for the winter with your own hands.

The main reasons for the violation of thermal insulation

It may seem strange to some people that there are cracks and distortions in modern plastic windows. However, such a problem does exist and occurs quite often. She may have several reasons:

• home shrinkage;
• improper installation of windows;
• loosening of the mechanism;
• seal wear.

One of the reasons for the cold in the house is the old seal

Depending on the cause, it is necessary to carry out thermal insulation. It is advisable to start work on a dry day in the warm season. This will greatly simplify the process. However, the problems can often be too serious to delay. In this case, it is better to carry out warming immediately.

Identification of problem areas

Before proceeding with the insulation, it is necessary to find and identify all the places that need thermal insulation.. Particular attention should be paid to the joints, as well as the junction of the walls to the frame. You should also check the slopes and the window sill. To determine the areas where cold air enters, you can use a regular lighter. It should be carried out over all possible places of blowing.

Violation of thermal insulation can cause condensation on the glass

Condensation, frost or drafts can also indicate an area that needs insulation. Depending on what is the cause of the violation of thermal insulation, it is necessary to think about how to fix it.

Work progress

It should be noted right away that if you insulate plastic windows for the winter with your own hands, the guarantee for them will automatically disappear..

If the owner nevertheless decides to carry out the work on his own, it is necessary to find a place for a draft. Sometimes it happens that it occurs due to depressurization of double-glazed windows. Unfortunately, in this case, it will not be possible to carry out high-quality insulation on our own. In most other cases, this is quite real.

Slope insulation

If voids appear under the slope lining, this means that it is necessary to carry out its repair. Finding them is quite simple: this is done by tapping on the surface. Where the sound will be more sonorous, there is an empty space.

The old insulation under the slope lining must be replaced

In this case, you need to remove facing material. Under it will be a heater. In most cases, foam serves as a heater. If the problems are not too serious, it is enough to simply add material to the places where the voids form. When the insulation has already served its purpose, it must be replaced. The material can be the most diverse: basalt wool, polystyrene foam, foam, etc..

After replacing the insulation, it is necessary to check the facing material. If the sheet has cracks or other serious damage, it must be replaced. It is better to use PVC as a cladding or plastic panel. Such materials not only look good, but also provide excellent thermal insulation.

Styrofoam can be chosen as a slope heat insulator

Insulation of street slopes is carried out in the same way. However, if the apartment is located above the second floor, you need to turn to professionals. It will not be possible to carry out work without special equipment.

Replacing seals

In plastic windows, one of the most quickly worn parts is a rubber seal. After several years of operation, it loses its properties and ceases to perform its functions. To increase the life of the seals, you can use a special silicone grease (this is done twice a year). However, if the material has already worn out, it must be replaced.

To replace it, you need to pry off the glazing bead that holds the double-glazed window. After that, it must be removed. Now the rubber is easily pulled out of its groove.

Replacing the sealing tape will increase the thermal insulation of the window

New material should be cut off (it is better to leave a margin of 5-6 cm and cut it to the desired length after installation). Before assembly, make sure that there is no dirt on the site. If necessary, the seal can be fixed with glue.

Pressure setting

In modern plastic windows, the window sash pressure can be adjusted. This is done by rotating the eccentrics (located at the end of the sash). A 4mm hex wrench is used for adjustment. On the eccentric itself there is a risk that helps determine the adjustment. If it is on the side of the street, then the pressure will be weaker.

modern windows allow to exhibit summer and winter mode sash pressing

Setting the position of the sash relative to the frame

In the sash hinges there is another mechanism with which you can adjust the sash. Adjustment is carried out by tightening the screws.

Materials for insulation

For high-quality insulation, the use of additional materials may be required. Here are some of the most common heaters.

How to stick a heat-insulating film

The most common type of energy-saving film is shrink film. It needs to be heated to stick. The technology for applying such a material will be discussed below.

Energy-saving film significantly reduces heat loss in the room

Important! After sticking, it is extremely difficult to tear off the film. Therefore, before starting work, it is necessary to weigh all the pros and cons.

The main mistakes in the work

Many owners begin to carry out work on insulation in the cold season. Doing this is not worth it. And the reason is not only the inconvenience that such insulation will bring. Many formulations that may be required require specific temperature regime. Therefore, take care of how to insulate plastic windows for the winter, better in spring or summer. If this did not work out, you need to choose a calm and dry day for work.

Quite often, the owners are somewhat negligent in the search for places where drafts occur. Under no circumstances should you do this. Even the smallest cracks and gaps can cause a large amount of heat loss. Therefore, all of them must be eliminated.

When working with polyurethane foam, it is necessary to strictly maintain the thickness of the layer.

As you can see, it is not so difficult to insulate any plastic windows for the winter with your own hands. However, before starting work, you need to seriously think about whether it is worth doing at all. The most common cause of drafts and high heat loss is poor-quality window installation. If so, then you need to contact the installer, who should correct the shortcomings.

Now many people are replacing wooden windows with plastic ones. However, during operation, their tightness may be violated. People are faced with the question of how to insulate plastic windows in such a way that both the violation of integrity is corrected and the air from the street enters the room less. It is important to understand what is the cause of the problem and solve it, and then make an isolation.

Why is it blowing from plastic windows

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

1. Marriage in production.
2. For the manufacture of windows, low-quality plastic was used.
3. Bad fittings were installed.
4. Mistakes were made during installation.
5. Poor quality seal material.
6. The slopes were not properly insulated.

How to determine the cause

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

The reason may lie in the incorrect adjustment of the fittings or in the lack of installation for winter mode. To do this, try to open the window and look at the lock. Not everyone can independently determine the problem and make settings, so it’s better to call the wizard. Sometimes the reason is in violation of the window geometry. In this case, there is a poor clamping of the sashes, due to such an abutment, drafts occur. Will need a complete re-installation of the double-glazed windows.

Another way to diagnose is to check the condition of the seal. It probably causes moisture to blow or leak (condensate forms) if it is of poor quality or heavily soiled (remove all dust). Under the influence of low temperature, it loses its elasticity. You should touch it with your hands, checking for elasticity. If the reason is the wear of the insulation, then it needs to be replaced.

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

When is the best time to insulate?

The problem of blowing windows occurs during the cold season. In the summer, people either do not notice this, and 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 composition requires a special temperature, it can not be used in winter weather. There is a plus of warming in 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 ways of thermal insulation, so each person can choose the most convenient for himself. Insulation for plastic windows is as follows:

1. Polyurethane foam is a fast and affordable method. However, the foam is short-lived, it is adversely affected by temperature changes, ultraviolet radiation, air.
2. Mineral wool is a safe and fire-resistant modern material.
3. Window film is good to use as insulation for the glass itself.
4. Silicone sealant is reliable, while inexpensive.
5. Styrofoam is used to eliminate gaps in window slopes.
6. Warm mixtures are applied outside.
7. Glue construction tape over the sealant, which will improve the effect.
8. Facade paint has a high weather resistance. It is easy to apply to any surface.
9. The primer dries quickly and is easy to apply. She is frost-resistant, she 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 the master, because:

• insulation of slopes and ebbs from the outside can be dangerous, especially if the window is higher than the second floor (you can fall and break);
• to properly insulate, it is important to know the whole technological process installations;
• the window is still under warranty.

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

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

1. Remove old foam from all openings around the window. To do this, use a hard brush, sticks and brushes.
2. Thoroughly rinse and wipe the surface of the window sill and slopes with a cleaner to degrease and eliminate dust.
3. Cover the resulting cracks with putty and plaster, then fill with mounting foam.
4. If a sealant is used instead polyurethane foam, then after its introduction into the slot, it should be glued on top with construction tape. To carry out work, a knife and scissors should be at hand.
5. Install heat-saving film. The window frame is cleaned of dust and pasted over double sided tape. The film is measured to the size of the window, then carefully applied and smoothed. To avoid bumps and bubbles, you need to blow it with a hairdryer.

Outside

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

1. Styrofoam of the required size must be glued to the slopes, and all visible cracks must be closed with glue.
2. A special mesh should be placed on top of the foam, and then plastered.
3. Align the plaster with a water-repellent layer, apply a primer.
4. Paint the resulting slopes, which will create an additional energy-saving protective layer from the wind.

Inside

Insulation of plastic windows inside must be done as carefully as possible, using for this different ways. Thermal insulation will contain the following steps:

1. Insulate the slopes of plastic windows inside. To do this, apply mounting foam.
2. Put plastic on top of the foamed slopes.
3. Adjust fittings. This is done with the help of an eccentric by means of rotation.
4. Replace seal. This element must be changed every 5 years. During this period, it loses elasticity and begins to pass air.

How to insulate the window sill of a plastic window

You can often feel the movement of cold air under the windowsill. If the crack is visible, then 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 foam. Stages of window sill insulation:

1. Remove window sill.
2. The wall on which it was located should be well cleaned of dirt and dust, after which all cracks and problem areas will be visible.
3. Cracks can be closed with mounting foam.
4. When the foam hardens, cut off the excess with a knife.
5. Prime the entire surface.
6. Apply sealant to all joints and corners.
7. Plaster.
8. Install the window sill.

As winter approaches and the weather gets colder, you notice a draft moving through the apartment. By placing your hand near the window on a windy night, you find a source of agonizing coolness. Enough to endure this and sleep under three blankets! There are many ways to insulate windows. They range from simple to complex, from virtually free to quite expensive, from "old-fashioned" methods to modern technologies. In this longread, we tried to collect the most effective methods.

Before we take decisive action, let's consider possible reasons draft coming from the windows. It would seem that wooden windows retain more heat due to their material, while plastic windows, a relatively new achievement in science and technology, are simply designed for heat and sound insulation. Then why can they let a draft into our house?

1. Unfortunately, poor-quality window installation is quite common. Sometimes employees of installation companies, who call themselves professionals, have a very superficial idea of ​​​​the installation of window blocks.
2. The second reason may be partly related to the first - an attempt to save on the installation of plastic windows. Companies often reduce the price by saving on insulation, foam, and the installation itself. Subsequently, low-quality windows are much more expensive due to the need to additionally insulate them.
3. Even if cold air does not seep through the gaps, the windows themselves may be to blame, such as the old "single-layer" windows, which provide only a thin glass barrier between the house and the street, but not cozy warmth.
4. Skewed windows and loose fitting of the window frame to the wall also threaten heat loss. Sometimes this happens due to the deformation of the building, which is especially common in old wooden houses.

It is wise to start by diagnosing the situation. Determine the most critical places from which the wind blows. Where does the cold come from: from the windowsill or window sashes? Maybe the problem is a worn seal or poor-quality slopes?

To determine the exact place from which cold air is blowing, you can simply run your hand over the surface of the window block. If this method fails to identify the problem, light a candle or lighter and move them around the frame - the fire is more sensitive to drafts.

Look at the windows when it's raining. Moisture accumulated in certain place, will point to gaps and crevices. When moisture builds up in the corner of a window or along one of its edges, the problem is probably in the joints. Moisture that builds up in the middle of a window pane could indicate some type of crack in the glass.

Perhaps the wind is blowing due to a poor-quality seal. Try putting a piece of paper in an open window and closing the window completely. If the paper is easily pulled out as soon as you pull the corner of the sheet, then the seal is not pressed against the frame well.

Before you choose a method of insulation from the available ones, you should think about the goals of insulation. It is clear that temperature control is the main concern, but what compromises are you willing to make? Will you be able to refuse in favor of cheapness beautiful view, restrict the flow of light or block access to the window?

You also need to consider cost. Some materials cost almost nothing: say, sealant can be bought for a couple of hundred rubles. More reliable and durable solutions will cost more and may require the help of a specialist, but in the long run may be a worthy investment.

Ask for help or insulate windows with your own hands?

To insulate windows, you have, in general, only two options: do all the work yourself or contact a professional. With your own hands, it is enough to simply insulate the window sill, the frame contour, the window opening inside the room or replace the seal. If any defect appears during the warranty period, the installer will have to fix all the problems. In addition, it is worth resorting to the help of installers if external insulation work is required, and the window is located at a considerable height - its replacement or repair work may be associated with an increased risk, and experts know exactly how to properly insulate plastic windows from the outside.

It is worth remembering that it is better to insulate windows before the onset of winter - then the working conditions will be more comfortable. In addition, sealants and some other Construction Materials can only be used in a certain temperature range, otherwise they lose their properties.

How to insulate plastic windows with your own hands

If you need to insulate a window opening, then mounting foam is suitable. Expanding, it fills the voids in the opening and prevents the movement of air. However, foam is a short-lived material exposed to low temperatures and will be suitable for a small gap. Also a popular heater is mineral wool with heat and sound insulation. She is resistant to high temperatures and easy to install.

Silicone sealant will also help to insulate window frames. It is best to use an inexpensive tool when working with it - a lever syringe. The sealant also blocks moisture, making windows resistant to mold and mildew. It is also worth choosing a transparent sealant - so it will not be noticeable if it accidentally hits the glass.

Before applying sealant or expansion foam, it is worth checking exactly how much they expand - to determine this, apply a small drop to the corner of the window.

Another way from the category of "cheap and cheerful" is to plug the cracks in the windows with technical cotton wool, and then seal them with masking tape. Previously, instead of adhesive tape, fabric or paper strips with laundry soap paste were used. But when using this option, its fragility is obvious, and it will not completely eliminate blowing.

A good and inexpensive insulation for plastic windows is foam rubber: cash costs will be minimal. Remove the film from the adhesive surface of the insulation and press the foam window insulation in the required places. With the onset of warming, it is very easy to remove. However, if moisture gets in, the insulation may lose its tightness.

How to insulate the slopes of plastic windows

To insulate the slopes of plastic windows, you can use the most different materials- sandwich panels, drywall, polystyrene foam or polystyrene foam. However, foam is the most fragile of the listed materials and tends to accumulate moisture. If it is necessary to insulate the window from the outside, dry mixes for finishing the slopes will help.

First you need to carefully process the cracks - eliminate possible contamination and remove the old mounting foam. If you chose drywall for insulation of slopes, then the sequence of actions is as follows:

• we cut blanks of the required sizes from drywall and process them with a moisture-resistant primer, wait until the blanks dry out;
• insert drywall sheets in the slot;
• we fill the small gaps left between the drywall and the wall with mounting foam;
• after the foam has hardened, we complete the cosmetic repairs with a primer and paint.

External insulation works are carried out at temperatures up to +5 ° C, otherwise building materials may lose some of their properties.

You can use a special heat-saving film for window insulation. It transmits light into the room and at the same time does not "release" infrared radiation. Such a film not only saves the heat of our house, but also helps to get rid of the effect of "weeping windows", that is, from. Also, windows on which a heat-saving film is pasted are characterized by greater strength. Before starting work, it is important to wash the glass, treat it with a degreasing agent and wipe it dry. Next, you need to stick the film so that its "metal" side looks out onto the street. The film is glued not only on the glass itself, but also with an overlap on the frame. Some manufacturers make films on a self-adhesive basis, but some types of film require adhesive tape. To prevent bubbles and wrinkles on the film, use a household hair dryer.

A simple and inexpensive life hack that will help you cope with a draft is to attach bubble wrap to the window. Choose film with large bubbles as it will generally handle cold air better. Trim the bubble wrap so that it overlaps the window frame slightly. Spray the window with water from a spray bottle, then "glue" a sheet of cut wrapping film onto the wet glass. You can secure it with double sided tape. The “bumpy” side should face the glass. The film should set without difficulty and remain in place for several months. If desired, you can apply a double layer of film for better thermal insulation. The only negative is that this method blocks the view from the window, but the light will nevertheless enter the room.

Sew a plain fabric to fit the width of the window. Fill it with some loose solid material like sand, rice, or polyester, then place it along the bottom of the window. Heavy materials (denim, corduroy) in this case will retain cold air more effectively than light materials (cotton, knitwear, etc.).

We replace the seal

If the problem is a worn seal, you can replace it yourself by choosing the right one in a hardware store. It is also better to choose a sealant in black: black is the natural color of rubber, and impurities of other colors can spoil the quality of the product. After the old seal is removed, it is necessary to clean the grooves from dust and dirt, treat the corners of the frame with glue and cut off the excess with scissors. The resulting joint also needs to be treated with glue.

People have been using wooden windows for a very long time, so the question “How to insulate old wooden windows?” there are many answers.

• Very old way used by our grandparents - gluing wooden windows newspapers. They were soaked in water and plugged cracks with them. The space between the glass and the frame was sealed with paper strips. Of course, “paper will endure everything,” and it is possible to spend the winter with it, but in the spring it will be very problematic to remove particles of newspapers. In addition to the banal inconvenience, there is also a risk of damaging the window covering.
• If old windows need to be insulated quickly, and the aesthetic side of the issue is not very important to you, plain paper will also do. To make paper putty, you can grind up old newspapers, soak them in water, add clay or crushed chalk, and seal the cracks with the mixture. To fix the putty for windows, it is enough to use adhesive tape. However, this method is short-lived and, most likely, will last only one season.
• As a heater for wooden windows, you can use foam rubber - ordinary or tubular. It will be effective if the wooden sashes are already dry and do not fit snugly against the frame. Previously, foam rubber was nailed with small cloves, but now you can use ordinary masking tape. This material can serve faithfully for a couple of years, then it will begin to deform and will need to be replaced.
• When insulating wooden windows, you can also use a sealant. It is necessary to remove the wooden glazing beads holding the glass with a screwdriver, apply sealant and install the glazing beads back - preferably new ones, since the old ones often break during dismantling.
• Wood tends to crack. Therefore, often the frame is covered with a network of small cracks through which heat can escape. To repair them, you will need to clean the glass from the decorative coating, fill the cracks with molten paraffin, home-made putty, sealant or special putty, and then re-coat the frame with paint or varnish.

In practice, plastic windows are not as perfect as advertised. They perfectly pass not only sound, but also cold. So what's the deal? After all, according to the characteristics window profiles superior to wood in all respects? The answer is trivially simple - having adopted European manufacturing technologies, domestic manufacturers still cannot insulate them with high quality.

It is not surprising that 90% of Russians before winter are wondering how to insulate plastic windows? After all, our cold is not a joke. Simple building foam is not enough for thermal insulation.

Before insulating plastic windows with your own hands, it is necessary to evaluate the scope of work. Firstly, thermal insulation will have to be done both inside and outside. Secondly, the window sill will also have to be dealt with.

The thing is that the installation of plastic windows is often accompanied by significant damage. As a result, the holes between the window sill and the wall are more than impressive.

Due to the inept installation of the wall, whole bricks are missing. And builders, in order not to add work themselves, most often decide to insulate such holes with garbage and cement. This result cannot be called satisfactory. So that builders use mounting foam.

It is not surprising that the insulation of the window sill of plastic windows is a mandatory item in preparing for winter.

Important! To insulate plastic windows, you need to wait for warm and calm weather - this is a guarantee of safety and quality.

Other reasons requiring immediate insulation of plastic windows for the winter include:

1. Wall seating.
2. Worn-out heater.
3. Loss of tightness due to incorrectly installed slopes.

In the first case, it is enough just to adjust the fittings and everything will be in order. The heater, if necessary, can be easily replaced with a new one. But with depressurized areas you have to tinker.

We define critical places

It is very important to know exactly how cold air enters the room. To do this, you need to take a lighter and hold it around the entire perimeter of the plastic window. Pay special attention to the places where the frame adjoins the wall. The window sill and slopes are also worth checking. If you don't have a lighter, use your open hand.

Important! Pay special attention to accessories. Very often, domestic firms use low-quality components to save money.

Presser setting

Over time, under the influence of mechanical and climatic factors, the sealing gum may lose volume. Because of this, air begins to penetrate into the room. Fortunately, in order to insulate plastic windows, it is not necessary to change the gasket. It is enough to adjust the clamping mechanism.

Important! If the gasket is completely worn out, it will have to be replaced.

To insulate plastic windows by adjusting the mechanism, it is necessary to find protruding cylinders in the slots of metal plugs. They are called trunnions and go into the hooks on the frame.

To insulate the frame, move the hooks to the position you need. Or adjust the trunnions. To change the position of the hook, you need to loosen the bolts. Moving towards the street increases the pressure, and towards the room it decreases. Here detailed video how to insulate a plastic window yourself by setting the clamping mechanism:

Heat-saving film

Film for insulation of plastic windows allows you to significantly reduce heat loss in the house. However, for its application to have the desired effect, it is necessary to properly prepare the surface. For this, you will need the following tools:

• stationery knife;
• scissors;
• scotch.

First, the surface must be cleaned of dust and dirt. Wipe the glass thoroughly (a layer of dirt and dust makes it difficult to penetrate sun rays inside). To check the quality of the cleaning, take the paper and press it against the glass, a distinct creak should be heard.

The perimeter of the box is glued with double-sided tape. The edges of the film are separated with a clerical knife. Cut it with scissors to fit the window and stick it on the previously attached adhesive tape. Take a hair dryer and blow warm air over the film. The resulting swelling burst with the tip of a knife. This is the easiest and cheapest way to insulate platinum windows.

Insulation of slopes of plastic windows

Material

To insulate the slopes of plastic windows with your own hands, you need to stock up on the following materials:

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

Materials are used for insulation of internal and external slopes. Their correct application will provide an additional layer of protection and good thermal insulation.

Advice! If the gap is more than 40 mm, insulate plastic windows with polystyrene foam or isover. The thickness of the material is 2-3 cm. Building foam is ideal for small gaps.

How to insulate the slopes of plastic windows from the street

First of all, safety is important. If you are above the second floor, it is better to call industrial climbers for this job. Without problems, you can insulate a plastic window with your own hands inside the loggia. The algorithm of work is the following:

1. Cut off the rest of the construction foam.
2. Treat the slopes with a primer with antibacterial additives.
3. Apply plaster if necessary.
4. Cut out the foam tiles according to the size of the slopes. Spread mounting glue on them and press them to the surface. For greater reliability, use dowels.
5. Set the corner.
6. Apply glue to the tiles, put a fiberglass mesh on top. Wait until it dries and coat with glue using a spatula.

At the end of the insulation of the slopes of plastic windows, paint the surface with water-based paint.

Attention! Below is an informative video "How to insulate the slopes of plastic windows?"

Important! Painting work can be carried out only after the mounting adhesive has dried.

Insulation of plastic windows from the outside avoids the formation of condensate. In addition, the room becomes much warmer.

How and how to insulate the slopes of plastic windows inside

Sometimes after ripping out old windows, the interior slope looks like a battlefield. Not surprisingly, constant drafts near the window blow out all the heat. In addition, shreds of polyurethane foam have an extremely unaesthetic appearance. The warming process includes the following steps:

1. Cut off unnecessary mounting foam.
2. Apply a primer to the slope, preferably with an antibacterial effect, so that mold does not appear.
3. Mix the mortar - make plaster.
4. Clean the surface and re-primer.
5. Cut out styrofoam boards to the appropriate size.
6. Scratch the surface of the foam, grease with glue and attach to the surface.
7. Wait until it dries, and install the corner, putty.
8. Fasten the trim.

The finish can vary. The most commonly used plaster and paint. Drywall is also in trend right now. Here is a good video on how to insulate the slopes of plastic windows from the inside:

How to insulate the window sill of a plastic window

Over time, under the influence of mechanical loads and thermal factors, the foam becomes unusable. Cracks appear, in addition, this sealant tends to dry out.

To insulate the window sill of a plastic window, you will have to buy a can of foam. Its average price is 200-300 rubles, depending on the volume and quality. It is best to give preference to European brands.

Remove the old foam and run the dispenser along the entire length of the frame base. This insulation does not cope very well with small gaps. They are best insulated with silicone sealant.
