Heat-saving film for windows: rules for using heat-insulating film

Advantages and disadvantages of heat-saving material

The use of thermal film has many positive qualities, among which it is worth noting:

Strengthening. Heat-saving material increases the strength of glass up to 8 kg/cm². When broken, the glass does not crumble into fragments, but remains glued to the film.
Saving. After gluing the film onto a single-chamber double-glazed window, its energy efficiency becomes comparable to a two-chamber design.
Protection of interior items from fading.
Almost 100% UV blocking.
Blocking IR radiation within 30-99%.
Depending on the type of material, one-way light transmittance.

Thermal film protects well from sunlight and retains heat.
However, thermal film also has disadvantages. The most basic is the almost complete reflection of ultraviolet rays, which negatively affects indoor plants. Therefore, if you use heat-saving film, then provide your plants with additional lighting with photo lamps that provide the radiation spectrum required for their normal growth and development.

The second drawback is the lack of effectiveness in spring and autumn. At a time when centralized heating has not yet been started, the thermal insulation coating will prevent the penetration of heat from the sun's rays into the room.

The film also has the unpleasant property of reflecting radio waves, which can affect the quality of signal reception going to a mobile phone or television receiver. This is due to the fact that metal spraying is used in the production of thermal insulation film.

Advantages and disadvantages

The solution has a number of advantages:

minimal thickness, high light transmittance;
possibility of gluing wooden and plastic double-glazed windows;
ease and efficiency of installation, no need for specific knowledge and tools;
affordable price;
fire safety;
environmental friendliness.

The only significant drawback is considered to be susceptibility to deformation under intense mechanical stress. The service life of the product is 1-2 years.

Do-it-yourself insulation of windows with thermal film

Before installing the “Third Glass” film on a plastic window, you should prepare tools such as a stationery knife, scissors and a household hair dryer. These simple tools are available in almost every home. It is easier to install with two people, but you can do the job alone. For detailed video instructions on installing heat-saving film in an apartment, see the end of the article on the website.

Do-it-yourself insulation of plastic windows with thermal film

Instructions for thermal film “Third Glass”

Start insulating roof windows with a small window opening. The surface of the frame should be treated with a degreasing compound and dried. Next, double-sided tape, included in the kit, is attached around the perimeter of the glass unit; The film in the package is folded in half; it should be separated and cut out. Cutting is done in accordance with the size of the window, taking into account the fastening of the thermal film with tape. Check the dimensions of the film by applying it to the window opening being processed; Remove the protective strip from the tape and carefully glue the film to the double-sided tape

Do not pay attention to possible folds, the main thing is that the film is securely attached around the entire perimeter of the frame with double-sided tape; Blow the film with hot air using a construction or household hair dryer; under the influence of temperature, the material will shrink. As a result, the heat-saving film will stretch and become perfectly smooth over the entire area.

Stages of installing heat-saving film on a window

Insulation of plastic windows with heat-saving film

An important advantage of this material is that it increases the strength of the glass unit - the glass will not scatter in different directions into small pieces, which will reduce injuries. The film can be used to insulate wooden and plastic frames; the effect of the material can be compared to installing a double-glazed window. The film reduces the heat transfer of energy from a warm room to a cold one near a double-glazed window.

We will give some more important recommendations based on reviews. When insulating windows for the winter, it is better to install thermal film in October-November. It is recommended to remove it in May, as daylight hours increase. If the film accidentally breaks during installation, do not be upset - the tear can be quickly repaired using ordinary tape.

Installation

Typically, heat-saving films for windows are made on a special adhesive base, although there are also types that are held on the glass due to surface tension.
Therefore, the installation method will depend on the selected material. It is worth noting that before starting installation you need to prepare the glass yourself. It is first thoroughly washed and then treated with a degreasing compound.

Next, apply the material to the glass, smoothing the surface with a soft rag to remove air bubbles. For these purposes, you can also use a special tool that is very similar to a brush for car windows.

At the final stage, cut off the remaining film with a mounting knife, straightening the edges.

It should be noted that the price of such installation is very low, and its simplicity will allow even inexperienced craftsmen to carry out the work.

Advice! It is worth noting that it is recommended to install the film on glass that is heated to room temperature. Otherwise, small defects may appear on it due to lag from the surface.

Categories of heat-saving film

It is not recommended to purchase cheap thermal insulation coating that will crack or peel off when exposed to the sun.

It is worth paying attention to strong and durable materials. High-quality thermal protective film for windows is divided into three categories:

Self-adhesive. It resembles the film that is glued to the screens of phones and tablets. It's not that easy to stick on. This work can be done efficiently by specialists or those who have extensive experience.

Usually this material comes with a backing, the edge of which is carefully removed and the coating begins to be applied to the window. Gradually moving the backing away, glue the entire canvas

This work is difficult to do on your own; there is a high probability of material distortion. Heat shrink. Attached to the window frame using double-sided tape. An air gap is formed between the window and the material, which is a good heat insulator. The attached film at first looks like a wrinkled plastic bag. To smooth it out, you need to direct hot air from a hair dryer onto it. Under the influence of heat, the coating smoothes out and takes on a normal appearance. Film for soap solution. Externally, it resembles car tinting and forms a durable thermal insulation layer. Anyone can apply this canvas. It is advisable to use soap without aromatic additives (laundry soap, baby soap).

How to install thermal film correctly?

Thermal film for window insulation is attached by performing the following simple steps:

We glue the double-sided transparent tape that was included with the film onto the previously prepared frame;
Upon delivery, the material arrives folded in two layers, so it is necessary to separate them;
Cut the film, taking into account the need to apply about 20 millimeters to the tape, check whether you have measured correctly;
Remove the protective paper strip from the tape glued to the frame;
Attach the film to the tape, not yet paying attention to the small wrinkles that appear (it is better to do this step together);
Since the film is heat-shrinkable, in order for it to level out and become smooth, we blow it with warm air from the center to the frame; for this purpose we will need a hairdryer;

Guide to insulation with paraffin and sealant

To eliminate small gaps, you can buy silicone sealant. You need to wash the windows in advance and wait until they are completely dry. Such insulation must not be performed at air temperatures below +5 degrees.

To eliminate small gaps, you can buy silicone sealant

The sealant is very convenient and easy to apply using a construction gun specially designed for this purpose. It is better to remove excess material immediately before it dries. In the future, to remove any leaking sealant, it will be enough to wipe the surface with a cloth slightly moistened with gasoline. You can simply carefully pick it off the glass using a knife.

One of the options for insulating a wooden window

Small cracks can also be sealed with paraffin. To do this, take several paraffin candles or buy ready-made material right away. The paraffin needs to be melted, taken into a syringe of suitable volume and carefully filled with it into each existing crack.

Large defects can be repaired with an ordinary clothesline. Any other lace will do. The rope is tightly pushed into the gap, after which it is filled with paraffin.

Such insulation will last at least 2-3 years. For the rest, focus on the condition of the thermal insulation and add new paraffin if necessary.

Cost and reviews

The price category of material and components depends on many factors:

Manufacturer's mark (brand).
Thickness.
Size of canvas (the larger the area purchased, the cheaper).
Possible delivery services.
Call a specialized worker who can correct some of the nuances.

Consumer Reviews

User Evgeny. “It seems that I bought normal windows from a well-known company with two cameras, but in winter I noticed ice on the bottom of the glass unit - this really surprised me. I read an article about film and hired workers. They installed it, and all the problems began to resolve themselves. I’m happy, but I don’t know about others.”
User Nataporshe. “My husband installed the film on the windows, at first I didn’t feel any special differences, but later I paid attention to the temperature in the apartment. Previously, with the same boiler operation, the rooms were cool, but now they are quite comfortable.”
User Kessler. “I installed the film last year, around August, and have not torn it off until now. I didn’t find any visible defects and I think I’ll only take it off when it breaks. I'm satisfied."

To save heat, not only high-quality windows and their timely repair are necessary, but also the use of an auxiliary product by the owner - polymer film.

Despite its unimpressive appearance, it has many advantages, and the main one is maintaining heat in the house. The low cost of the material only increases its popularity among potential consumers.

Shooting with a thermal imager - the need for insulation is obvious

Hello. Today I’ll tell you about independent insulation of windows in an apartment and in a country house. Thermal insulation of windows is a very important stage of property renovation, which should not be neglected if you are interested in the energy efficiency of your home and reasonable heating costs.

How film works

The basis for the production of the film is the polymer polyethylene terephthalate (PET), the thickness of which, depending on the manufacturer and operating conditions of the heat-saving film, can vary from 80 to 200 microns. Due to the high ductility of the heat-saving film, it can, to some extent, increase the strength of window glass, especially when glued directly to its surface. But the biggest advantage is that accidentally broken window glass will not shatter into small pieces. They will remain tightly “glued” to the film in the window frame.

But protecting window glass, of course, is not the main purpose of using heat-saving film.

Thanks to a microscopic layer of rare earth metals deposited on its surface by plasma evaporation and subsequent deposition of metal vapor in an argon environment, a layer is formed that, without interfering with the penetration of rays of the visible spectrum through the film, changes, due to refraction, the transparency of the film for rays of the UV and IR parts of the spectrum Sun. These rays are not visible to the human eye. But IR (infrared) rays are responsible for heat transfer; their film, when refracted, reflects into the room, and it is due to this that its “heat-saving” effect is manifested. But it reflects the rays of the UV (ultraviolet) part of the spectrum, which make up a significant segment of the sun’s light, preventing them from penetrating into the room.

The sun's UV rays have a strong ionizing effect. Being vital for the body in small doses, they contribute to the production of D vitamins in the human body, normal photosynthesis of indoor plants and purification of indoor air from pathogens.

Is it possible to insulate the walls inside an apartment using wallpaper?

Recently, the trend of insulating the walls of the house has gained wide popularity. It is not always possible to insulate from the outside, but you can insulate from the inside at any time. There is a wide range of functional insulation materials on the construction market. The advantages of such materials:

prevent the occurrence of fungi and dampness on the walls;
big savings on heating in cold weather;
protect walls from condensation;
level the surface for gluing wallpaper, eliminating roughness and unevenness;
additional sound insulation;
long service life.

Another advantage of wallpaper insulation is that the work is easy to do yourself, which saves money.

What are cold bridges

Cold can penetrate into a living space not only through glass, but also in other ways - through elements that are in one way or another in contact with the environment. Areas where windows are in contact with the outer surface of the walls, as well as leaky panel seams in multi-story buildings, significantly reduce the thermal resource of the room, which means that not only the windows themselves, but also each of these areas must be insulated.

Replacing windows even with the most modern double-glazed windows without additional insulation of the above parts will increase the heat resource of the room by only 15-20%. If you take a comprehensive approach to insulating a room, the heat resource can be increased by 45% or more.

Energy-saving window film will keep your home warm

According to research by experts, heat loss through glazing of windows is about 30 percent, so in the cold season, due to heat leaks, 70% of the heat must be spent on heating in winter. In addition, heat loss through glass is three times higher than leakage around frames.

It is for this reason that the issues of thermal insulation and energy saving remain relevant today.

Such losses can be reduced in various ways. For example, fill the cracks with polyurethane foam, as a result of which losses are reduced by up to 90 percent; insulate the walls of the building outside and inside, increasing the thermal insulation of the building by 60 percent. In this case, installing metal-plastic windows can even help.

Recently, energy-saving film for windows has begun to be in demand, thanks to which it is possible to reduce heat loss by up to 70 percent.

Negative aspects of using film that you need to know about

Since the film almost completely reflects UV rays, indoor plants, whose growth directly depends on the Sun, begin to suffer because of this. To prevent the plants from dying, they have to be additionally illuminated with photo lamps. That is, this problem is solvable. However, where is the energy saving? The photo lamp must be turned on at least 12 hours a day to ensure normal plant growth and compensate for lost sunlight. Even the most economical lamps will not save you.

What happens to the heat energy if the film is used in spring and autumn, when the heating is already turned off? Since the film does not allow natural solar heat from the street to penetrate, dampness will settle in the apartment and it will be cold.

Few people know about another property of film - they reflect radio waves. That is, radio signals that go to an indoor antenna or mobile phone will be reflected by the coating of the film. And, vice versa: the signal from the mobile phone will be reflected back into the room. Conclusion: cellular communication in buildings where the film is pasted will be very poor.

You should not use film for greenhouses and greenhouses, because plants need the full spectrum of sunlight.

There is no point in gluing the film if the apartment has modern windows with high-quality thick double-glazed windows. But when restoring old windows, it, on the contrary, will serve as a good help. You also need to take into account the fact that the film needs to be changed annually.

What to do if the film is inflated or minor damage appears?

The insulation can “play” for two reasons: to inflate - if the sealing work is poorly done, to sag - if the film was glued in a room with sufficiently large temperature fluctuations.

In the first case, the film will have to be removed, the flaws removed, and pasted again. In the second case, you need to wait until the heating is turned on and the room is warmed up, and then use a hairdryer to fix the problem.

If damage occurs, there is no need to completely change the film, since this problem can easily be fixed with tape.

Benefits of using film on windows

When using film on windows there are the following advantages:

By using a coating on the glass for insulation, you do not interfere with the natural circulation of air through the wooden frame.
Significantly increases strength and prevents the risk of glass shattering when broken.
Small sound insulation, perfectly prevents sounds from falling raindrops.
Installation is very simple and any beginner who has never even tried this process before can handle it.
There is no need for specialized tools and materials for installation or maintenance.
It is possible to use a film with an external mirror surface, while the appearance from the inside remains unchanged.
Complete protection against fogging and the formation of any type of condensation on the glass surface.
Windows become less dirty, since any dust and stains do not remain on the surface.
Due to its composition, even severe frosts are not able to freeze pieces of ice on the surface of this coating.
Very high wear resistance and durability. As a rule, such a film can last much longer than the window itself. Even in case of damage, the surface can be easily repaired using the simplest stationery transparent tape.
Low level of interference with electromagnetic radiation.
Film performance is not lost even after prolonged use or if damaged. If a scratch or hole is repaired with tape, the properties of the film remain unchanged.

We make gluing

The entire installation process must be carried out very carefully and not rushed. In this matter, it is better to spend an extra half hour than to get a low-quality end result in the form of an unacceptable appearance or completely damaged material.

Work should be carried out with rubber gloves, and the glass should be at normal room temperature. The film has two sides, front and inner, they must be accurately separated in advance so as not to be confused during installation.

Let's start the installation:

You should wash the window thoroughly and wait until it dries completely.
The fittings and all handles are removable so as not to get caught during gluing.
In order not to make mistakes when adjusting, make a small margin of about two centimeters to trim off the excess and adjust the film to the ideal size.
The film for insulation is rolled out and cut to the resulting dimensions with scissors; here it is better to measure everything several times so as not to make a mistake, since the film must be glued in one solid sheet.
Now you need to moisten the glass with a soap solution, and degrease the frame using regular medical alcohol.
Double-sided tape is glued around the perimeter of the window.
Then the film must be attached to this tape. When installed correctly, it should be completely invisible.
Air bubbles are removed using a soft rubber or plastic spatula, and for better smoothing, the surface is heated with a hairdryer.
It is best to secure the edges of the film with glazing beads. They can be removed before gluing or after, as is more convenient for you.
The holding double-sided tape can be completely removed. We return the fittings and handles to their place.
At the very end, remove the protective layer and the window will be completely ready.

Low-emission energy-saving film

When installing energy-saving film on a window, the room becomes much warmer. It prevents wave radiation from cooling the interior through the glass and thus retains up to 42% of additional heat.

In the spring-summer period, a window on which a heat-saving film is installed does not allow the room to overheat. This coating on the glass blocks the penetrating thermal rays of the sun. These qualities of the film make the window a real heat insulator throughout the year.

This effect is achieved due to the physical properties of refraction of sunlight. Thermal reflective films are produced using special technology only by manufacturers from the USA (4 are produced in the world).

Low-emission films have a main characteristic - emission coefficient, i.e. the ability to re-emit energy. The lower the value of this coefficient, the more effectively it retains heat in the room.

According to our measurements, not a single film, except Ecolux70, provides a noticeable heat-saving effect on double-glazed windows. A slight effect is visible with a thermal imager only on single glass.

Only 3 films in the world give an effect on a double-glazed window: Ecolux70 from SolarGard, Enerlogic from LLumar and Thinsulate from 3M.

Energy-saving film is an effective heat insulator in winter and summer.

Why does it blow from a plastic window?

Determining the reason for the blowing of a plastic window begins with whether it is new or old. In the first case, the problem can be safely attributed to poor quality installation of the product, which means that the installers will have to solve it.

In this case: poor-quality installation seam of plastic windows

Often, plastic windows are installed by companies whose workers do not have sufficient qualifications. Mistakes are also possible when trying to install windows yourself. That is why it is not recommended to save on specialists when replacing PVC windows with new ones. But if you are faced with a problem with improper installation or an obvious manufacturing defect, warranty repairs should cover all additional costs.

In the second case, the appearance of a draft is associated with the characteristics and duration of operation of the window. Among the reasons are:

“Warpness” of the window frame and depressurization of joints due to shrinkage of the newly built house;
Wear of window components - seals, sash pressing mechanisms, etc. after a long period of use;
Untimely or absent maintenance of PVC windows.

Some of the problems can be fixed yourself, which will save both time and money. Others are best left to specialists. Namely:

if replacement of fittings is necessary (“original” parts can often be ordered only through the installer);
when performing external high-rise work (for windows located above the second floor);
when insulating a window in winter (specialists will be able to do this quickly and without significant heat loss in the room).

With your own hands you can insulate the window from the inside or along the contour, replace the sealing material, and insulate the window sill.

Where to buy energy-saving film?

Buying such a film now is not particularly difficult, since it can easily be found in almost every construction and hardware store.

In addition, when purchasing plastic windows in recent years, manufacturers initially began to install films on their products.

Sometimes film is sold in subway passages, but in such cases there is a high chance of purchasing a low-quality fake.

Types of heat-saving films

Experts distinguish types of energy-saving film based on product manufacturing technology:

with application of rare earth metals or noble alloys to the base;
with ceramic surface coating of polyester.

According to the installation method, thermal films are divided into:

Wet glued. The energy-saving film is applied after preliminary preparation and degreasing of the surface by pre-wetting the glass with detergents, soap solution or colorless shampoo.
Dry glued. Installed on a previously prepared surface, in places of contact with the surface of the frame, double-sided tape is glued to it, after which the surface of the film is treated with a hairdryer, due to which the effect of heat shrinkage is achieved.

The second method of insulating windows with film has become very popular due to the ease of installation while ensuring absolute tightness of the connection and the absence of areas with an accumulation of air bubbles after treatment.

Why do you need a vapor barrier?

To protect against water from the outside, wind and waterproofing is used. It prevents the insulation from weathering and exposure to precipitation. An air ventilated layer approximately 50 mm thick is also usually provided, which allows dangerous condensation to be removed from the surface of the insulation.

Purpose of wall vapor barrier

But when designing the walls of a house, it is necessary to take into account that moisture can also come from inside the building. This is especially true for a wooden structure or any other built from vapor-permeable materials (for example, frame). To protect against moisture from the inside, a vapor barrier is used. It is needed to prevent the movement of vapors inside the walls of the house and prevents the mineral wool from gaining moisture.

What is thermal film and how it works

The technology for the production of heat-insulating material is based on the physical characteristics of sunlight, consisting of UV and IR rays. Thermal film is a complex structure consisting of several layers of polyethylene terephthalate, the thickness of which reaches 80-200 microns. Each layer has a thin metal coating applied using a plasma discharge method in an argon atmosphere. Silver, gold, as well as nickel and chromium alloys can be used for coating.

Thanks to a special application technology, the metallized layer does not interfere with the entry of visible spectrum rays into the room and changes the light transmittance of the film due to their refraction. Infrared rays carry out heat transfer, and the thermal insulation material, by refracting, reflects them inside the house or apartment, resulting in a heat-saving effect. The material reflects UV rays, which make up a significant range of the spectrum of sunlight, preventing them from penetrating into the room.

The high ductility of the thermal insulation film glued to the surface of window glass significantly increases its strength. In addition, if it is broken, it will not crumble into small fragments, but will remain on the film. However, the protective properties are rather a side effect, since it is designed to save energy.

What materials can be used for internal insulation?

The main types of insulation for wallpaper:

Plaster mortar with thermal insulation properties. They have several types of filler:

based on sawdust. Eco-friendly, but not suitable for rooms with high levels of moisture (balcony, bathroom);
from expanded polystyrene. Excellent noise suppression and thermal insulation. But it is not resistant to fire and is easily flammable;
in the form of perlite or vermiculite (mineral base). Fireproof, but not moisture resistant;
foam glass.

Cork is environmentally friendly and safe. This type is durable, has sound insulation, thermal insulation, and hides wall defects. Minus – the price is above average.
Rolled - Polyfoam, made of polyethylene foam. On one side, the material has no additional coating, and on the outside it is covered with special durable paper. This allows you to glue different types of wallpaper, even heavy ones.

Made in roll form. There is a type with a foil reinforced coating on one side.

Maintains the climate in the room, is not susceptible to moisture and mechanical damage. Has a long service life.

Extruded polystyrene foam is used less frequently. But before mounting on the wall, the surfaces need to be leveled.

Sometimes plasterboard is used for these purposes, but installing such a finish requires additional room space, and the installation itself is labor-intensive.

There are special warm wallpapers on sale that consist of several layers: oilcloth, foil and spunbond. But this type is not easy to glue, because they are heavy, and the range of colors is poor.

Mineral wool insulation technology

For external insulation of window openings with mineral wool you will need:

mineral wool,
plaster,
adhesive solution,
reinforcing mesh,
perforated corners,
dowels,
putty knife.

The insulation process should be carried out according to the following scheme:

Measure the width of the slopes and cut pieces of reinforcing mesh with an overlap of 10 cm.
Place the mesh on the slopes with an adhesive solution.
Place a layer of mineral wool on top, having previously coated the surface with glue. Its width should be 1–2 cm greater than the slope.
To avoid the formation of air space, the slabs should be applied as tightly as possible to the surface of the slope.
Trim the remaining strips of cotton wool protruding beyond the edge of the slope.
After complete drying, apply glue to the edges of the insulation and wrap it with the remains of the reinforcing mesh.
Install perforated corners around the perimeter.
Wait until it dries completely and apply glue to the screed again using a spatula. The adhesive solution in this case should be slightly thinner than the original one.
Apply primer and then paint the window façade.

Mineral wool insulation scheme

On the inside, mineral wool is used in combination with PVC slopes or sandwich panels.

Let's get started with window insulation

By eliminating all external cracks, we reduced heat loss, but not significantly. By placing your palm on the window frame, you can make sure that there are no drafts. In order for the insulation to be carried out efficiently, you need to pull out the glass and eliminate all the cracks. Before you insulate your windows, you should stock up on a few tools. We will need a flathead screwdriver and a spatula. Sequence of work:

use a screwdriver to pry up the wooden glazing beads and carefully remove them;
remove the glass from the window frame;
Use a spatula to clean the frame from dust and old paint;
Using a syringe, apply sealant over the entire surface where the glass is inserted;
install the glass in its place;
we nail the glazing beads.

The first thing you need to do when disassembling a window is to remove the glazing beads. However, this does not always work out. The beads are thin and often break. We advise you to stock up on some glazing beads before starting repairs. You can always install new ones instead of broken or damaged parts.

The glazing beads are difficult to pry off. They fit tightly to the frame. Therefore, before starting work, it is worth sharpening the screwdriver with a file. This can also be done on a sharpening stone. A sharp screwdriver will easily separate the wooden elements of the window frame.

You need to remove the glazing beads very carefully. First, the glazing beads should be “torn off” or “lifted” along the perimeter of the frame, only then removed. The glazing beads are also removed in a certain sequence. First, remove the bottom bead, then the side ones, and at the very end the top one, which will hold the glass. By following this sequence, there will be less chance of breaking the fragile glass.

When removing glass, it is better to wear cloth gloves. Sometimes the edges of the glass have sharp edges. Gloves will protect your hands from cuts.

How to mount film

It depends on what kind of film you are using - heat-shrinkable, self-adhesive or soap-based. In any case, you will need an assistant. The film can be sold in sheets folded in half or in rolls.

The first preparatory stage is washing and drying the window.

After which a layer of soap solution is applied to it from a household sprayer. To prepare it, you can use children's shampoo not colored with pigments or colorless dishwashing liquid. After that, a film cut to the size of the glass is applied to the generously moistened glass of the window. Be sure to first use the top edge, and use a soft rubber roller or a rubber scraper for washing windows to remove excess soap solution from under the film. First, from top to bottom - in the middle of the glass, and then - from the glued middle of the film to the sides. If possible, avoid the formation of large air bubbles. The film will not stick in these places. Small wrinkles and liquid bubbles will disappear on their own as the film dries and the film will completely straighten out.

Self-adhesive films are also applied in a similar way. Only the base protecting the adhesive layer is not removed from the entire film at once, but a narrow strip is peeled off from the upper edge of the film. It takes two people to work. Having glued the top edge, the person at the top smoothes the glued film with a soft cloth, and the person at the bottom gradually removes the protective layer, pulling it towards himself. The main thing is not to rush.

Installation of shrink film is also best done by two people. Double-sided tape is glued along the perimeter of the window frame, a blank 2 cm larger than the glass is cut out of the film and glued to the tape along the entire perimeter. Top first, while an assistant must pull the bottom edge of the film by the corners, preventing premature gluing of the film. The resulting wrinkles and folds are not scary.

After gluing, the film is blown with hot air from a hairdryer, and it straightens and stretches itself. Shrink film is especially effective on the balcony, where it acts as a second or third glass.

Finish coatings

Usually, when installing heat-saving boards with glue, they are plastered using a forming mesh for gypsum composition, and fiberglass for putty. These measures will prevent cracking of the finish coating.

After all the plastering and putty work is completed and the walls have dried, we clean the surface with a fine abrasive mesh and paint it with a water-based emulsion of the desired shade.

A vapor barrier for the external walls of a wooden house is needed when insulating with mineral wool. This insulation is very susceptible to moisture. Due to its high hygroscopicity, it is able to accumulate water. At the same time, the heat-shielding properties of the material are significantly reduced. To prevent unpleasant consequences, it is necessary to protect the mineral wool from moisture on all sides.

Do-it-yourself window insulation

There is nothing complicated in the process of finishing a window with film - not only a qualified specialist, but also the owner of the house can handle this task. No special skills or tools are needed, but some rules must be followed.

Required materials and tools:

film;
special colorless double-sided tape;
roulette;
long ruler;
pencil or marker;
construction knife or scissors;
cotton gloves;
regular hair dryer;

Step by step guide:

Initially, you need to make sure that there are no cracks in the window frame. In plastic windows this unpleasant nuance practically does not occur, but in wooden windows it may be present.

Wooden windows contain frames in their design, which entails the presence of many joints through which cold air can pass through. For high-quality sealing of seams and other cracks, transparent sealant or silicone is used.

You can proceed with further actions only after they have completely dried:

The inside of the window frame needs to be washed. To do this, you can use household chemicals or soap solution.
Afterwards, the frame is treated with degreasers (preferably ethyl alcohol 96%).
Double-sided tape is glued along the edge of the frame (along the perimeter).
Next, the film unfolds on a large table. If it is folded in half, it needs to be stratified. To do this, it is advisable to blow on the joints. Holding the two edges, it gradually separates.
It is necessary to measure the horizontal and vertical dimensions of the glass unit in advance with a tape measure.
The recorded indicators are transferred to film, with a tolerance of 1.5-2 cm for attaching it to tape.
You can cut the material with a knife or scissors, because it is very pliable to cut.
The protective paper layer is removed from the adhesive tape attached to the frame.
First, the cut out area must be leaned against the upper horizontal plane of the tape and pressed carefully.
Next, you need to pull it a little and press the edges of the film against the vertical strips of tape.
In the lower part, the fastening process is identical to the previous ones. Thus, the film is fixed in the desired position and is ready to serve for a long time.

Recommendations in progress:

Before completely sealing the window with film, you must thoroughly wash the glass.
To ensure that no traces (fingerprints or other contaminants) remain on the canvas, work must be carried out with cotton gloves.
If folds appear on the surface of the material during the process, this can be corrected using a regular hair dryer. To do this, it is necessary to spray the film with a stream of hot air escaping from it - which causes shrinkage.
During the process of gluing the film, it is not recommended to stretch it too much, because the surface may burst. And it is almost impossible to repair it, unless you stick a strip of tape, but over time the defect will become noticeable.
If the window is large enough, it is better to carry out the work together.
Do not allow the film to sag or touch the glass - this will not provide good heat conservation.

Rules for laying insulation

To prevent the formation of condensation, cold bridges, mold and fungi, it is worth understanding how to insulate the walls from the inside. Builders recommend:

use vapor barrier materials. They will eliminate dew point shifts, moisture accumulation and extend the life of the structure;
buy thermal insulation with an adhesive base - this way you can save space in small rooms;
the house is equipped from the inside with forced or natural ventilation to control humidity levels;
monitor the steam-heat balance, selecting the thickness of the thermal insulation inside in accordance with the average daily temperature in winter;
consider any situation. If you don’t know how to insulate a wall in an apartment from the inside if there is mold, listen to the experts. They advise “treating” the surface with antifungal primers;
control the quality of thermal insulation at joints and load-bearing partitions.

Important! Installation operations are carried out on a completely dry surface.

Product characteristics

Glass transmits about 35% of the heat from the room, so it is necessary to seal it. Externally, the protective film resembles culinary polyethylene, but it is made of polyester. The high-molecular structure allows the sun's rays to pass through and at the same time does not release heat from the room. The thin material becomes additional glass and functions as a large thermos.

Thanks to the transparent surface, the product is almost invisible on the window. There is no glare on it, since the film does not have a specular reflection. The maximum thickness of the material is 0.14 mm, while it can withstand tension. It does not react to chemical detergents, so they can be used to clean dirt.

The film does not attract dust and does not allow ultraviolet and infrared rays into the room, which can harm the health of humans and pets. The material is environmentally friendly and does not cause allergic reactions. The product has a small mass, and during heat treatment it shrinks.

Thermal insulation of wooden windows

Don’t rush to get rid of such windows, because they can be restored

Do you have wooden windows in your apartment or house and even foam insulation doesn’t protect you from the cold? Of course, you can replace old wooden structures with plastic double-glazed windows. On the other hand, you can leave environmentally friendly wooden windows, but make them much warmer.

Elimination of heat loss using Swedish technology

Now I’ll tell you how to insulate wooden windows for the winter using Swedish technology.

Many people have heard something about Swedish technology, but not everyone knows what it is. In a few words, the Swedish technology for the restoration of wooden windows is a complex work, as a result of which a wooden window in terms of thermal conductivity will be comparable to plastic double-glazed windows.

Tubular seal in groove

The main stages of working with old windows using Swedish technology are listed in the following diagram.

Features of using polyurethane foam as insulation

To seal cracks and reduce heat loss, you can use ordinary polyurethane foam. It is extremely easy to use and allows you to obtain the highest quality thermal insulation

You just need to show maximum attention and accuracy during work in order to seal all existing cracks. After the foam has dried, its excess should be cut off with a sharp knife, and the insulation itself should be hidden with something

Polyurethane foam

To mask such thermal insulation, you can use homemade putty. To prepare it, you need to take part of the chalk and 2 times the amount of building plaster. Mix the ingredients, dilute the mixture with water to a semi-liquid state and spread on the foam. Of course, it will not be possible to completely hide traces of insulation, but at least the polyurethane foam will not be so conspicuous.

Thus, to independently insulate windows for the winter, you can use a wide variety of materials. Choose the most suitable and convenient option for you and get started. Good luck with your work and have a warm winter!

Scope of application and operating principle

The main material is polyester, used in creating not only heat-saving film, but also for reflective, anti-glare, tinting, energy-saving and sun protection materials.

Excellent technical indicators allow it to be used in other areas:

Thermal insulation material for glass facades.
Additional insulation for greenhouses and greenhouses.
Finishing natural solariums and light transparent roofs.
Insulation of loggias and balconies.
In rare cases, to create thermal insulation for walls during renovation work.

It is due to the air “vacuum” that heat cannot quickly turn into a cold state. Thanks to it, natural resources for heating and, of course, money are saved.

What to consider when choosing heat reflective film

First of all, you should decide on the place of its application. So, to create a heat-reflecting screen behind the battery, you need to remember that the thermal conductivity of aluminum is very high. In order not to heat the wall behind the radiator, but to reflect the heat into the room, there must be an insulating layer between the film and the wall. The ideal choice in this case is films based on polyethylene foam.

They are also great for organizing heated floors, allowing you to minimize the thickness of the cake - for interfloor ceilings you do not have to lay a thick layer of insulation, limiting yourself to only heat-reflecting film. For such floors, it is better to choose films with aluminum foil. Its thickness of 10 microns will allow maximum heat distribution, eliminating possible cold bands when laying pipes. The sprayed layer copes worse with leveling the overall thermal field.

But if you need to insulate a bathhouse, it is metallized films that show excellent results. They are not subject to corrosion and reflect 60% of infrared radiation. Only canvas-based films can be laid on the insulation, and any options can be mounted on “bare” walls.
