How to insulate plastic windows with your own strength. How to insulate a plastic window for the winter with your own hands? Insulation of windows with foam rubber and adhesive tape

24.05.2020

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. Seemingly, wooden windows due to their material, they retain more heat, and plastic ones - 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?

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.
The second reason may be partly related to the first - an attempt to save on installation 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.
Even 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.
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 buildings. 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 unit. 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 that has accumulated in a certain place will indicate 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 a defect occurs within warranty period, the installer company 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 subject to low temperatures, and will fit with a small gap. Also a popular heater is mineral wool with heat and sound insulation. It is resistant to high temperatures and easy to install.

Insulation of window frames will also help silicone sealant. 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;
fill in the small gaps left between the drywall and the wall, 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.

Highly old way used by our grandparents - sealing wooden windows with 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, it is also suitable plain paper. 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.

Before the advent of plastic windows in our lives, homeowners each autumn shared with each other ways wooden window insulation.

The urgency of this problem is obvious, since the windows are made of wood, having many positive properties, dry out over time, they become noticeable cracks and crevices.

If drawings from hoarfrost or frost appear on the window glass, even with a slight frost, you can confidently speak about violation their tightness.

It is better to take care of the insulation of windows even before the onset of frosty days, because before insulation, no matter which method of sealing them is chosen, they need to be washed. With the onset of cold weather, this procedure is difficult to perform.

Insulating wooden windows, homeowners are trying create space, as close as possible in its properties to hermetic.

Primarily the slots of the outer frame are eliminated, allowing cold outdoor air to enter the intraframe space, and then the inner frames are also insulated.

main ways used for window insulation are:

installation of sealing rubber bands;
careful sealing of cracks;
gluing closed gaps with paper, tape or cloth.

Shouldn't be forgotten and about glass - they must also be installed tightly. Today, silicone sealants are used for this purpose.

Important: before starting work on the insulation of wooden frames, they must be thoroughly washed and the glass strengthened.

Film insulation technologies - conventional and heat-insulating

Most often, the film is used to insulate old wooden windows. country houses. To perform this work qualitatively, it is necessary when choosing a material pay attention on its characteristics.

The film must not only be durable and have a high degree of transparency, but also be quite frost-resistant.

Film insulation is carried out from the outside windows. For fastening, a construction stapler is used. The size of the brackets for it should be no more than 8 mm. To avoid damage when attaching the film, additional pieces of film material should be placed under the brackets.

Window film needed stretch evenly so that gusts of wind cannot tear it. If the fixed film is torn, then you should not try to repair it by gluing it with tape. A complete replacement of the material on the entire surface of the frame is necessary.

Important: the material must be of high quality, therefore it is better to purchase a film for window insulation in specialized building materials stores, and not in the market.

Thermal insulation film, not so long ago developed for the construction of greenhouses, immediately found application in the insulation of wooden windows. This type of film is a composite material with unique properties.

One of her sides has an extremely thin metallized layer. Its thickness is only 2 molecules, so light passes through it unhindered.

In addition to preserving heat, the film protects the room from infrared radiation, delaying about 90% of rays. This property of the heat-insulating film reduces the heat loss of the glass and protects the furniture in the house from fading.

Typically, homeowners use this type of material to insulate frames from the outside, however, experts say that insulation with such a film inside the house gives greater effect.

In any case, the insulation process begins by cutting out a piece of film, the size of which corresponds to the size of the frame glass. It is necessary to provide small overlap.

Then it is applied to the glass with a spray gun. soap solution, on which the film is glued. Bubbles are carefully removed from under the film with a rubber spatula.

Metallized film layer should point towards the glass. It is quite possible to do this work on your own, however, specialists work with metallized film faster, and appearance will provide more aesthetically pleasing.

Important: before starting work on insulation, the glass surface must be thoroughly cleaned of dirt and washed. To protect the glass from the appearance of fingerprints on it, work with the film should be carried out with gloves.

Swedish wood window insulation technology

Work on the insulation of wooden windows according to the Swedish method can be called a partial restoration of the window. This technology will not work if the frames are very old and cracked. The work is being done in the following order:

The frame is removed from the window opening, thoroughly cleaned of old paint and irregularities. Then, at its ends, along the entire perimeter, a line is drawn with a pencil along the entire perimeter of the frame. A groove will be made along this line.
The groove in the frame is cut using a special tool designed for woodworking - a milling cutter. In order to ensure the required groove size, a suitable nozzle is used. If there is a window in the frame, then similar actions are performed on it. Particular care must be taken when cutting the groove in the corners of the frame so that its depth matches the depth of the groove at the ends.
The process of insulation is completed by installing a tubular PVC profile in the groove. With high-quality insulation in the corners, the profile is carefully cut so that there are no overlaps and jams, since this will worsen not only the quality of the insulation, but also the functionality of the window. The PVC profile is fixed in the grooves by gluing.

The advantage of this method is that it can be used without problems, regardless of the time of year. Main disadvantage- the impossibility of performing insulation on their own, and the services of specialists have a rather high cost.

Warming by the Swedish method at a price can be compared with the installation of a plastic window. However, many homeowners prefer to have wooden windows, so Swedish technology is for them. popular method insulation.

Quite often, warming only the frames does not give the desired result, since the draft in the house appears not only because of the cracks in them.

The reason may also be poorly fixed glass. The fact is that in frames that have served for a long time, the glasses were fastened with putty.

Over the years of operation, the old putty, which initially firmly held them in the frame, has lost its qualities, becoming fragile and fragile. Sometimes she crumbles completely, and the glass is held only with the help of small carnations.

Naturally, they do not prevent the flow of cold air into the room. Therefore, the insulation of wooden windows must begin with the fastening of glass, performing this work in the following order:

The old mount is removed - putty and glazing beads. If the glazing beads (slats that hold the glass) are worn out, it is better to purchase new ones in advance.
The glass is removed, and the frame is thoroughly cleaned of paint drips and putty residues.
Alkaline solution removes traces of putty from the glass.
The frames are washed, wiped dry, and then their inner perimeter is coated with a colorless silicone sealant.
Glass is installed in place, fixing it with glazing beads using special window studs. Beads must be fastened very carefully, since pinched glass can crack when the temperature changes.
The noticed gaps must be smeared with sealant, the excess of which is removed with a damp cloth. After a few hours, the glass can be washed with a window cleaner, and then you can start insulating the frames.

For insulation of wooden frames usually use seals provided with an adhesive layer. In the assortment of hardware stores there are foam rubber and polymer seals. Polymer sealing tapes will last for several years, while allowing you to open windows

The foam sealing tape will have to change annually, because from the ingress of water it soaks, losing its properties. To glue the sealant, you just need to press it firmly around the perimeter of the frame with the adhesive side.

If the gaps in the frames are too large, then you will have to caulk them, filling them foam rubber or cotton. Then you need to stick masking tape or strips of paper on them. You can also use fabric strips.

Fabric and paper can be glued to the frame with a soapy solution that is easily washed off in the spring. After the solution dries, the fabric becomes airtight.

Important: to avoid the appearance of condensate in the inter-frame space of the window, bags with any substance that absorbs moisture (adsorbent) should be placed in it. These include activated charcoal, salt, soda and silica gel.

When choosing a heating method can be combined various options insulating materials. Most often, budget line heaters are used, while obtaining the expected result.

The result of the work on the insulation of windows with wooden frames there will be a noticeable improvement in the climate in the house. Properly executed insulation will save up to 50% heat in the house while reducing heating costs.

How to properly insulate wooden windows for the winter - find out from the video:

No matter how good plastic windows are, over time they can begin to let cold air into the room. In this case, insulation is indispensable!

But before proceeding with the repair of window structures, you need to find the cause of the malfunction and determine a way to eliminate it.

It's blowing, but from where?

In the design of any plastic window, there are the most vulnerable places for through air flow:

The junction of slopes, ebbs and window sills
Sealant location
The point of contact between the double-glazed window and the window frame
window fittings

It is here that leaks and cracks most often occur.

The easiest way to determine exactly where it is blowing is to bring your hand to the window.

A more accurate result can be obtained using a candle flame or a lighter. If there is air flow, it will be directed inside the room.

You can check the tightness of window sashes with a simple sheet of paper. To do this, you need to put a sheet of paper between the wings. open window, and then close them and pull the edge of the sheet.

If the window sashes are in good condition, the sheet cannot be removed intact: it will tear. If, on the contrary, there are leaks, the sheet can be easily removed.

It blows, but why?

There can be several reasons for the failure of a plastic window. The most common:

Mounting errors a. As a rule, malfunctions associated with installation errors manifest themselves almost immediately, and they can be eliminated using the warranty. The installer is obliged to redo the poor-quality work.
Window block deformation due to building shrinkage. This defect is not common, but it cannot be completely excluded. The shrinkage of a properly built building can slightly deform the window unit, which makes it easy to fix the problem. If, due to shrinkage, a strong deformation of the window is observed, changing its geometry, then it is time to think about the strength of the building itself and start asking builders and the management company questions about its quality.
Installation of low-quality windows. This cause of windows malfunction is the most common and it is caused by an understandable attempt to save money. In addition, new windows look almost the same and a consumer inexperienced in construction matters can make right choice, paying more, sometimes it is very difficult. So window structures appear without a reinforcing profile, with poor-quality sealant and dangling fittings, which can barely withstand one winter. It is cheaper to replace such windows with high-quality double-glazed windows than to try to repair and insulate.
Window misuse leading to premature wear of sealing materials. According to the rules, windows can only be washed using special non-aggressive detergents be sure to wipe dry and lubricate the sealing materials with glycerin. Alas, not everyone does this, and not always.
Physical wear of the window structure and its individual components. Time does not spare window constructions, and even the highest quality windows begin to let in the cold over time.

Faults found, causes established: what to do?

There can be two further actions: call the wizard or do everything yourself. It is advisable to seek the help of professionals in the following cases:

Window under warranty
For self repair there are no skills, tools and desire
The window must be insulated from the outside, and it is located at a considerable distance from ground level. In this case, without professional equipment for working at height, it is simply impossible to do without risk to life.
Work is being carried out in winter time that requires a professional approach

If you still decide to insulate plastic windows yourself, determine which element of the window structure needs to be improved, and get to work after reading our recommendations.

Plastic window adjustment

Most common cause A malfunction of a plastic window is the skew of its wings due to operation. This is not a breakdown: just the windows need to be maintenance which you can do yourself.

The design of the window has two elements that ensure a tight fit of the sash to the window frame. They call them barrels and clamps. These two elements, when the window is closed, should go behind each other, ensuring its snug fit.

It is easy to check if the barrels and clamps in your window match: close it and try to loosen the window sash with your hands. If it is stationary, there is no need for adjustment. If there is a window frame movement, take a hex screwdriver in your hands and loosen the adjusting screws a little. By changing the position of the screws, it is necessary to achieve a tight closing of the window.

Seal replacement

Replacing the seal is a type of work that you can do yourself even without special skills. It's simple: the old seal is removed from the groove, and a new sealing cord is installed in its place. True, it is not worth rushing to replace the seal: its service life is at least 15 years. Perhaps the reason is not in it, but in the need to insulate the window opening.

Window opening insulation

It can blow from the cracks between the wall of the house and the window block. When installing a window, there is always a gap between its structure and the base base of the window opening. free space filled during installation with construction foam. If the window slopes are not sealed from the outside or are sealed poorly, over time, cracks may form in the seal, into which cold will rush.

You can insulate the window opening from the inside and outside. Interior work can be done at any time of the year. For this

remove internal slopes,
remove the worn seal
primer is applied to the cleaned surface
the prepared space is filled with mounting foam
after complete drying, excess foam is removed,
perform decorative trim slopes with PVC panels or drywall

The bulk of the work on the insulation of the window opening must be done outside the house. The most effective is the plastering of slopes.

For this:

They remove the old finish (it was loose and the barrel was blowing through it)
They clean the space between the window block and the wall from old mounting foam and other seals.
Fill the vacant opening with mounting foam and wait for it to harden
Clean off excess foam.
Seal all cracks and bumps with adhesive
Install mounting brackets
Mount the polymer mesh
Inflict plaster mortar over polymer mesh
Clean up the wall surface

It is best to insulate the window sill during its installation. If the part is already standing, but it is blowing from under it, you need to clean the space between the wall and the window sill, fill it with mounting foam and finish the wall surface.

Additional insulation

For additional insulation of the window, you can use the so-called energy-saving film, the task of which is to reflect the flow of heat, tending outward through the window opening, into the room. The film is glued to the surface of the glass with a reflective layer inside the room. True, you should not count on a great effect from its use: it is better to simply perform high-quality insulation of the opening and slopes, adjust the window sashes, achieving their snug fit and install a high-quality seal. And then for sure, your house will be warm and cozy!

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 so 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:

Marriage in production.
For the manufacture of windows, low-quality plastic was used.
Bad fittings were installed.
Mistakes were made during installation.
Poor quality seal material.
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 window.

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. AT summer period people either do not notice it, and with the onset of cold weather, the air from the street becomes palpable. 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:

Polyurethane foam is a fast and affordable method. However, the foam is short-lived, it is adversely affected by temperature changes, ultraviolet radiation, air.
Mineral wool is a safe and fire-resistant modern material.
Window film is good to use as insulation for the glass itself.
Silicone sealant is reliable, while inexpensive.
Styrofoam is used to eliminate gaps in window slopes.
Warm mixes applied outside.
Glue construction tape over the sealant, which will improve the effect.
Facade paint has a high weather resistance. It is easy to apply to any surface.
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:

Remove old foam from all openings around the window. To do this, use a hard brush, sticks and brushes.
Thoroughly rinse and wipe the surface of the window sill and slopes with a cleaner to degrease and eliminate dust.
Cover the resulting cracks with putty and plaster, then fill with mounting foam.
If a sealant is used instead of mounting foam, then after it is introduced into the gap, it should be sealed with construction tape from above. To carry out work, a knife and scissors should be at hand.
Install heat-saving film. The window box is cleaned of dust and pasted over with 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

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

Styrofoam of the required size must be glued to the slopes, and all visible cracks must be closed with glue.
A special mesh should be placed on top of the foam, and then plastered.
Align the plaster with a water-repellent layer, apply a primer.
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:

Insulate the slopes of plastic windows inside. To do this, apply mounting foam.
Put plastic on top of the foamed slopes.
Adjust fittings. This is done with the help of an eccentric by means of rotation.
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:

Remove window sill.
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.
Cracks can be closed with mounting foam.
When the foam hardens, cut off the excess with a knife.
Prime the entire surface.
Apply sealant to all joints and corners.
Plaster.
Install the window sill.

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

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

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

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

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

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

Why is it blowing from the window

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

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

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

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

What can you do yourself

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

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

mounting foam;
mineral wool;
Styrofoam;
expanded polystyrene.

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

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

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

Preparation for thermal insulation of the window unit

In order to insulate the window block, it is necessary to prepare:

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

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

External slope insulation

Quite often, owners of houses and apartments are wondering how to properly insulate the slopes of plastic windows. The first step on the way to improving the thermal insulation properties of the structure is the displacement of the dew point. This will eliminate the appearance of dampness and the development of fungus.

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

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

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

Thermal insulation of ebbs

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

Internal thermal insulation

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

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

Window sill thermal insulation

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

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

Warming by adjustment method

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

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

Alternative ways

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

As a heater are used:

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

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

If you want to understand how to properly insulate plastic windows, you can use electric heating. In this case, a heating cable is located around the double-glazed window, which will heat the spiral. Sometimes an oil cooler is installed on the window. The most technologically advanced method is the electric heating of a double-glazed window.

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

Using a special tool

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

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

Finally

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

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