Thermal film on windows: features, installation rules. Ceramic Energy Saving Film Heat Retaining Window Film

Heat-reflecting film is a rolled material on a woven or non-woven basis that reflects infrared radiation towards the source.

To keep you cool in summer, heat-reflecting window film will block infrared sunlight, but will not block natural light.

And in order to reduce heat loss in winter, an energy-saving film laid around the entire perimeter of the room will reflect heat back into the room, preventing the walls and ceiling from heating up aimlessly.

The scope of use of heat-reflecting films depends on their type - transparent or opaque. Transparent films are polymer-based (architectural). They are used to create a thermal barrier on the windows of houses and offices, to shade car windows and even to organize greenhouses.

Opaque films are quite diverse in structure and application:

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 battery, but to reflect 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 underfloor heating, allowing you to minimize the thickness of the pie - for interfloor floors you do not have to lay a thick layer of insulation, limiting yourself only to a heat-reflecting film. For such floors, it is better to choose films with aluminum foil. Its thickness from 10 microns will allow you to distribute heat as much as possible, removing possible cold streaks when laying pipes. The sprayed layer copes worse with equalization of the general thermal field.

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

Thermal reflective film Ondutis R Termo is perfect for reducing heating costs. Due to its characteristics, it provides up to 80% heat reflection. As a result, instead of heating the walls, thermal energy is used exclusively for space heating.

The light weight of Ondutis R Termo vapor barrier (70 m 2 /g) allows it to be used for warming light frame structures, and vapor permeability up to 10 g / m 2 per day provides maximum protection of the insulation from steam even in a Russian bath. At the same time, the film does not lose its properties at temperature drops from -40 to +120 degrees.

Solarblock IR-cut 7080. Tests with Testo 882 thermal imager.

Thermal reflective films have been around since the evolution of solar films. There was a demand for a more transparent and more effective coating than the classic mirror film. Thanks to the development of new technologies and experiments with new materials, this long-awaited product has been created that protects from solar energy and does not darken the room. And in the cold season, this heat-saving film prevents the heat from escaping through the glass.

IR or TSER?

These parts of the solar spectrum also make up half of what is converted into heat indoors. Therefore, when making claims about heat rejection, we should look at Total Solar Energy (UV+VISIBLE+IR) Rejected. Total Solar Reflection TSER is a parameter that describes the total amount of solar energy (UV+VISIBLE+IR) blocked or deflected from passing through the glass. The IR reflectance values ​​only help people understand that the film rejects the vast majority of heat from infrared radiation.

But this does not mean that if most of the IR is blocked, then almost no heat will pass through the film. It is also important to understand that without passing it further, therefore, it and the glass heat up. In order to avoid the appearance of cracks on the glass, we recommend that you familiarize yourself with the problem "".

Our film Winter-Summer.

We have tested the popular IR-cut 7080 ceramic film in medium heat waves from domestic heating appliances.

Spectral range (spectrum range):
- from 2,500nm to 10,000nm

Experiment conditions (conditions):
- DLATGS DETECTOR, 128scan, Resolution 4cm-1

Here is an example of a ceramic infrared emitter-heater ECZ 250w in the form of an E27 bulb, which we use for demonstration. Wavelength depending on power consumption 3.5 - 5 µm (3500 - 5000 nm).

Athermal glass and athermal films.

Glass.

To date, there are such types of films that are used for insulating double-glazed windows:

1. Plain polyethylene.
2. Energy saving.
3. Thermal insulation.
4. Reflective.

All of the above materials are able to effectively protect against the cold due to the fact that they do not allow heat loss in the winter season. They also reflect the rays of light inside the room, preventing them from escaping, which further maintains the desired temperature in the house.

Thermal insulation film

Thermal insulation film is an affordable and reliable thermal insulator for windows, which is manufactured using new technologies. The thinnest layer of this material is covered with a special molecular substance, which provides a thermal insulation effect. At the same time, it is absolutely transparent and does not damage the surface of the glass.

The main characteristics of this material:

1. Can repel dust.
2. It can be used both in the summer season and in the winter.
3. They can insulate not only windows, but also greenhouses, doors and loggias.

Also, the heat-insulating coating can also have an opaque structure, which makes it stronger. Such material can be used several times.

Installation of this material is carried out using the following technology:

1. First you need to prepare the surface of the window - clean it from dust. You will also need the following tools:
   • Scissors.
   • Scotch tape (double-sided).
2. If the window has gaps or cracks, then they should be repaired.
3. After that, double-sided tape must be glued to the frame.
4. Next, take out the cover and cut off the desired part. Tape it carefully. At the same time, it is very important not to pull the film itself with force, otherwise its integrity can be violated, which will lead to a deterioration in thermal insulation.
5. It is necessary to glue the material tightly so that it fits well to the entire surface of the glass.
6. Next, you should turn on the hair dryer and warm up the material so that it “lays” even better against the glass and, as it were, completely merges with it.

Polyethylene film

This is the easiest and cheapest way to reduce heat loss.

This material has the following advantages:

1. Low cost.
2. Ease of installation.
3. Ease of maintenance.

Its disadvantages are:

1. Insufficient heat storage.
2. The opacity of a material that does not transmit light.
3. The ability to use only once in one segment.
4. Will collect dust.

Installation of a polyethylene coating is carried out according to the following principle:

1. Measure the desired length of material based on the size of the window.
2. Prepare your frame.
3. Using sharp pushpins or tape, carefully attach the film around the entire frame, leaving no gaps through which heat could escape.

It is not difficult to take care of such material, you just need to remove dust from it in time.

Energy saving film

It is considered the most practical and effective, since it has the following advantages:

1. Maintains the desired temperature in the room.
2. Increases sound insulation.
3. Keeps cold out.
4. Doesn't let moisture through.
5. Protects the window from freezing, which increases its durability.
6. Increases strength in glass (especially if it has a third glass effect).
7. Does not transmit infrared rays.

Nevertheless, energy-saving insulation has its drawbacks:

1. In the spring, it can limit the flow of the sun's rays.
2. If installed incorrectly, it will be difficult to re-glue the film.

Installation of this material is carried out according to the following scheme:

1. Degrease the surface of the window frame with alcohol.
2. Glue double-sided tape around the perimeter and remove the protective strip.
3. Stratify the film itself (it is folded in half).
4. On a clean surface, cut it to the size of the window (also take into account a few centimeters for adding to the adhesive tape).
5. Carefully (it is better to do this with someone else's help) stick the film with tape, holding it from above and below on the sides. In this case, the material itself should be glued only to the frame and not touch the glass!
6. Warm it up with the warm air of a hair dryer and achieve until the insulation itself stretches over the window.

Reflective film

It differs from others in that it may not let the rays of the sun through at all, but at the same time effectively retain the heat that is in the room. It can be used all year round.

The advantages of this material:

1. Durability.
2. Big choice.
3. The effect even at a temperature of -35 degrees.
4. Suitable for any interior.
5. Keeps the heat coming from batteries and heaters.
6. Minimizes heat loss.
7. Due to the special aluminum coating, it reflects the heat emanating from the outside.
8. Protects furniture, wallpapers and plants from overheating and loss of color from the action of the sun.
9. Creates a comfortable microclimate in the room.
10. Thanks to light reflection, it protects from prying eyes from the outside, but, nevertheless, does not impair visibility from the inside.
11. Helps to eliminate the problem of overheating and has the effect of an air conditioner.
12. It has absolute transparency, exactly the same as ordinary glass.
13. Softens light and makes it more pleasing to the human eye.

The main disadvantage of reflective insulation is its high cost.

You need to glue this material in this way:

1. Prepare window cleaner, a knife, a rubber spatula and a water spray bottle.
2. Thoroughly wash the entire surface of the window and glass on both sides. Wipe dry so that there are no streaks.
3. Using a spray gun, apply a solution of soap, which was previously diluted with water, to the adhesive film surface and glass. In this case, you do not need to shake it strongly, otherwise a lot of soap bubbles will appear. This is necessary so that the soap makes it possible to calmly move the film over the glass surface to the desired position.
4. Attach the film to the stack. As soon as she "sits down", she should be carefully smoothed with a spatula from the center to the edges, and remove all bubbles from there.
5. After the entire surface becomes even, you need to let the film dry.
6. At the end, trim the edges with scissors or a knife.

It is necessary to take care of such material with extreme care so that it does not peel off. It is best to occasionally wipe it with a damp cloth or dust cloth.

Issue price

Here is the cost of these films per roll:

1. Plain polyethylene - 470 rubles.
2. Energy saving - 1450 rubles.
3. Thermal insulation - 970 rubles.
4. Reflective - 2630 rubles.

We will learn one of the ways to make your house or apartment warm. To maintain the desired temperature in living rooms and save on heating, thermal film on windows will help.

In anticipation of cold weather, many owners of houses and apartments are thinking about their insulation. Creating a comfortable temperature in living rooms, saving on heating are important tasks. One of the options for their solution is the use of thermal insulation film, which is glued to the double-glazed window. Experts claim that windows account for about 60% of all heat loss at home. Moreover, even if the profile of the double-glazed window is of high quality, the installation is carried out correctly, the slopes are hermetically sealed and insulated, the glass itself still accounts for up to 30% of heat loss. To make sure this is the case, a thermal imager will help you.

Functions

But many homeowners, even without a thermal imager, decide - the glasses need to be additionally protected from the cold! For this purpose, energy-saving, they are also thermally insulating, athermal films, which are often called the "third glass", are used. After all, they perform the functions of additional glass, becoming a barrier to the entry of cold into the room and the leakage of heat from the house.

Important! Yes, you can immediately buy triple-glazed windows, energy-saving, designed for severe frosts. But the thermofilm will definitely cost less. That is why it is in demand among the owners of apartments and houses who ordered double-glazed windows.

Remember how many homeowners used to just board up the outside of their windows with plastic wrap for the winter? Yes, it didn’t look very nice, you can’t open the window in winter, the street is practically invisible, but this measure helped to reduce heat loss through old wooden windows. Thermal films operate on the same principle, they look like ordinary polyethylene ones. However, they are easier to use, they are attached from the inside, they do not interfere with the ventilation of the rooms, they do not block the view from the window.

Describing the types of protective films for windows, we mentioned energy-saving ones. The thermal insulation film, despite its external similarity to ordinary polyethylene, is actually a polyester sheet on which an extremely thin layer of metal or ceramic is sprayed.

It is thanks to this layer, which is applied by the method of flame discharge in an argon atmosphere, that the thermal film gains the ability to keep warm air out of the house in winter, and in summer - to prevent the room from heating up excessively. According to experts, an energy-saving film on a window can raise the temperature in a room by at least 3°C.

Price

The cost of thermal films on windows can vary greatly. You can buy a square meter of such a protective coating for 50 rubles, or you can buy it for 500 rubles. The difference is in the properties of the film itself. The cheapest thermal films can hardly be called truly energy-saving, they create the effect of a thermos, serve as a “third glass”, but do not protect against infrared rays.

The second plus of expensive options is that such films combine several functions. They not only prevent heat loss, but also protect from sunlight, ultraviolet radiation. And they are also part of the anti-burglary protection, making it difficult to break the window with a stone or a hand tool.

In addition, expensive thermal insulation films are self-adhesive. That is, it is much easier to apply them on glass - the protective top layer is torn off and the canvas is carefully attached, while, of course, we must not forget about the need to remove possible air bubbles.

Sticking

If the film is not self-adhesive, you can attach it to the window in the following way:

1. Wash the entire window, degrease, wipe dry thoroughly so that there are no streaks;
2. A double-sided adhesive tape is attached along the prepared perimeter of the frame;
3. A piece of film of the required size is cut out from the purchased roll;
4. The upper protective part of the tape is removed;
5. The film is glued;
6. In order for it to stretch, let in sunlight and not interfere with viewing the surroundings, you need to walk on the surface of the film with a hairdryer - it stretches perfectly and becomes barely noticeable.

Important! Experts insist that the film should be glued to the frame, and not to the glass itself. In this case, an air heat-shielding pocket is formed.

Change the thermal film every year so that the protection of the room from heat leakage remains as reliable. We strongly advise you to additionally check the seals on the plastic windows, replace them if necessary. Wooden frames should also be checked and, if necessary, sealed. published

Insulating windows for the winter is one of the top priorities before the start of the cold season. An excellent solution to avoid such a hassle is to install plastic double-glazed windows, which can perfectly solve all your window problems. But there is not always enough money to buy expensive plastic window units, or even they cannot fully cope with the cold.

The solution to this problem is the use of modern technology, which helps to save heat and prevent external cold from entering the room. We are talking about a special heat-saving film on the windows.

What is this heat-saving film

This coating is produced from many incredibly thin sheets, each of which is covered with a special ultra-fine and thin metal coating. The role of the coating is played by various metals, such as chromium and nickel, gold, silver and so on.

Today, on the product shelves of stores, you can find dozens of different options for such a heater, but among them there are quite a few really high-quality ones. Since the quality cannot be determined by eye, it is necessary to ask the sellers for the appropriate quality certificates to make sure that the insulation film is really made from the specified materials and meets all standards.

What are the pros and cons of it

Like any other material, heat-saving film has its advantages and disadvantages, which you should definitely be aware of before making a purchase. Since some of them may not meet your requirements and money will be wasted.

Let's traditionally begin to consider what advantages it has:

1. Absolute transparency allows you to maintain a constant indicator of illumination of the room, and the presence of such a coating does not distort the visible picture through the glass.
2. The special composition not only prevents the penetration of warm air from the room, but also resists the hot scorching sun in summer. Thus, in the summer it will be cooler in your apartment, and you can save on air conditioning.
3. Thanks to its coating, window insulation film is able to block more than ninety percent of UV rays from penetrating. So, you will significantly reduce their impact on your body and the body of those around you.

Due to the presence of such indicators, the heat-saving film is a really significant competitor among all similar heaters. We figured out the advantages, let's move on to studying the disadvantages that are also present in this material:

• At the initial stage of spring, the insulation film will not work, since there will be nowhere for the heat to come from, the heating is turned off, and the sunlight is still not strong enough to warm the room.
• It is inefficient to use this method of insulation in tandem with high-quality plastic window and balcony blocks. Since the latter are already able to retain the main amount of heat, and the insulation film will only help to save five to ten percent, which is an almost negligible amount. It is best used with less insulated windows such as wood, aluminum or damaged windows.
• If you are an avid gardener and like to grow flowers, then you will not be able to use such a film. It blocks almost all ultraviolet light, which is necessary for the normal growth and development of plants.

Benefits of using film on windows

When using film on windows, there are the following advantages:

• Using a coating on the glass for insulation, you do not interfere with the natural circulation of air through the wooden frame.
• Significant increase in strength and prevention of the risk of glass spillage when broken.
• Slight sound insulation, perfectly prevents sounds from falling raindrops.
• Installation is very simple and any beginner who has not even come across 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 view from the inside remains unchanged.
• Full protection against fogging and formation of any kind of condensate on the glass surface.
• Windows become less dirty, as 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 allotted window itself. Even in case of damage, the surface is easily repaired using the simplest transparent stationery tape.
• A small indicator of interference with electromagnetic radiation.
• Film performance is not lost even after prolonged use or damage. If a scratch or hole is sealed with adhesive tape, the properties of the film remain unchanged.

We make sticking

The entire installation process must be carried out very carefully and not in a hurry. In this case, it is better to spend an extra half an hour than to get a poor-quality end result in the form of an unacceptable appearance or even spoiled 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 inside, they must be accurately separated in advance so as not to be confused during installation.

Let's proceed with the installation:

1. Wash the window thoroughly and wait for it to dry completely.
2. Accessories and all handles are removed so as not to hook them during gluing.
3. In order not to miscalculate when fitting, make a small margin of about two centimeters to cut off the excess and fit the film perfectly to size.
4. The film for insulation is rolled out and cut out with scissors according to the resulting dimensions, here it is better to measure everything several times so as not to be mistaken, since the film must be glued in one single sheet.
5. Now you need to moisten the glass with a soapy solution, and degrease the frame using ordinary medical alcohol.
6. Double-sided cattle are glued along the perimeter of the window.
7. Then the film must be attached to this adhesive tape. When properly installed, it should be completely invisible.
8. Air bubbles are removed with a soft rubber or plastic spatula, and for better smoothing, the surface is heated with a hairdryer.
9. The edges of the film are best secured with glazing beads. They can be removed before gluing or after, whichever is more convenient for you.
10. The double-sided adhesive tape can be completely removed. We return the fittings and handles to their place.
11. At the very end, remove the protective layer and the window will be completely ready.
