5 Ways to use Smart Film Window in 2022

Tinted film on double-glazed windows in a private house

Smart Film Window

To protect rooms from the sun, until recently, blackout tint film was mainly good for smart film window. Such a coating did not transmit light, but it did not save from overheating, as it accumulated energy itself.

Over time, manufacturers eliminate this shortcoming and today they offer a fundamentally new protection from the sun. This article will tell you about the types of new tint films, the main differences between them, the method of installation, and also help you choose the right polymer coating.

Types of dimming tint films and their main differences

Depending on the type of film for double-glazed smart film window, it helps to solve different problems. It can darken rooms, keep rooms warm, improve the safety of double-glazed windows, protect against overheating and provide privacy.

Thanks to this material, it is possible to quickly adapt windows to current needs. The properties of the films determine by the composition of the layer that applies to them during the production process.

The metallized coating is capable of reflecting different waves from the spectrum of sunlight, so it is this coating that largely determines the properties of the films.

There are more and more multifunctional coatings on the market that are able to simultaneously solve several problems – reflect the sun’s rays, keep warm, provide privacy and decorate smart film window.

Sun protection film

This type designs to protect the interior from overheating and reduce the intensity of natural light. Most buyers associate solar control smart film window with a color coating that darkens rooms. However, in fact, mass-dyed polyester intends for other purposes. It is good to decorate windows.

To protect against the sun, other films are produced today:

  • Reflective – have a mirror surface and darken the room.
  • A Thermal – do not let in ultraviolet and infrared rays, but do not darken the room.
  • Multifunctional – protect against overheating in summer, and help retain heat in winter.

Window tinting with an inexpensive sun-protection film with a mirror effect is obsolete. This method is mainly good only in cases where it requires darkening the premises with minimal costs.

Now thermal and multifunctional coatings are popular, since they almost do not reduce the light transmission of double-glazed smart film window. Such a reflective film glues to windows, doors, as well as balcony and roof glazing.

Mirror film visibility

A real mirror film does not impair visibility from the premises. Tinting plastic windows and aluminum or wooden structures with this coating allows you to protect yourself from the sun and provide privacy at the same time.

There are also smart film window with heat-saving and protective properties. This type of polymer coating is able to imitate a regular or bronze mirror and colored reflective surfaces with a gloss effect.

Such a film also calls anti-vandal or anti-burglary, since it is able to provide protection from the street.

At night, when the lamps turn on inside the rooms, the mirror coatings lose their effectiveness and cease to provide one-way visibility. This factor must be taken into account by the owners of premises on the first floors.

Impact film

All polymer coatings that glue over glass make smart film window impact resistant. The difference between them lies in the ability to withstand the impact of different forces. In addition, a protective film glues on the double-glazed windows to prevent fragments from flying apart.

That is, the polymer coating may have a low impact resistance, but in any case it will help protect against injury. However, such a one-sided window film cannot function as a basic protection. To ensure a higher level of security, it requires using a material with a thickness of multilayer polyester from 110 microns.

Decorative film

Such a tinting film glues on smart film window to decorate openings, shop windows and is often good for facade glazing. It is dye polyester. Therefore it accumulates heat and reduces the light transmission of double-glazed windows. When choosing a color, keep in mind that decorative films have different transparency.

Decorative films of the new generation are multifunctional. Thanks to additional spraying, they reflect heat rays and exclude heating of windows.

Such a protective film applies to double-glazed smart film window in cases where it is necessary to decorate windows and prevent temperature rise in the interior. This polymer coating may have a glossy surface with a glare suppression function.

Architectural and facade films

Architectural and facade smart film window is no different from polymer coatings known under other names. They also serve to provide protection from the sun and decorate buildings.

It’s just that these two terms are sometimes good as generalizing for all types of films – shockproof, decorative, sunscreen and a thermal. In some cases, a film with the effect of one-way visibility can be a facade film.

This is due to the fact that such polymer coatings are good in fully or partially glazed business centers and shopping malls to ensure privacy. Such films limit the view only from the side of the street. In addition, the outer film can call facade.

Films for euro windows

Euro windows include structures assembled from aluminum, plastic and wooden profiles. An additional feature of these models is the presence of double-glazed smart film window, tightness contours and modern fittings.

The film on euro windows applies in exactly the same way as on old-style carpentry structures. In all cases, it glues to the glass. That is, there is no fundamental difference between polymer coatings for different types of windows.

Exterior window film – how is it different from interior?

If windows fit with tinted double-glazed smart film window, which makes using body-tinted glass, internal films will not be suitable for providing effective protection from the sun. With this configuration, there is a high probability of overheating.

By the time the heat waves reach the reflective surface, they have already had time to heat the colored glass. On the way back, after reflection of the waves, the heat transfer process will repeat. That is, the use of internal films in such cases practically does not make sense. After all, the smart film window is still heated.


How to Use Smart glass to decorate windows?

In order to prevent overheating of smart glass dyed in mass, another technology must be used. In such situations, you need a solar control film for windows, which must be glued from the outside. It immediately reflects the sun’s rays and does not allow their accumulation by glass colored in mass.

Smart glass

Smart glass prevents premature depressurization of windows

To stick it on the upper floors, you do not need to hire a tower or industrial climbers. For these purposes, it is enough to remove the double-glazed windows from the light openings, apply a polymer coating on them and insert them back into the windows.

External tinting is also recommended for smart glass with conventional double-glazed windows. After all, the sun’s rays, until they reach the inner film, have time to heat the spacer frame and glass. In addition, its use prevents premature depressurization of double-glazed windows.

During the operation of windows, an imperceptible process occurs

  1. During daylight hours, the sun’s rays heat the glass. Even high-quality, well-polished material has impurities of substances that accumulate heat waves. As a result, the heated glass slightly expands.
  2. At night, the smart glasswindows cool down, which leads to a minimal reduction in the size of the glass?
  3. Due to daily expansion and contraction, the sealant layers on both sides of the spacer are gradually destroyed.
  4. There is an accelerated depressurization of double-glazed windows.
  5. Smart glassWindows retains heat much worse.

Smart glass has completely transparent layer

The exterior tinted window film has an additional completely transparent layer that protects it from damage. Thanks to him, the coating tolerates the effects of snow, rain, wind and dust. The level of wear resistance of this layer largely determines the effectiveness of the film.

Indeed, without it, the polymer coating located from the side of the street will very quickly lose its properties.

Light transmittance of tinted windows

The tinting film on smart glass windows should be glued taking into account building and sanitary and hygienic standards. These documents regulate the daily amount of natural light that should flow through window openings into the interior.

Scientifically, this process calls insolation – irradiation of vertical and horizontal surfaces in rooms with sunlight.

Since smart glass window tint film blocks the sun’s rays, indoor insolation may not be sufficient. It is better not to allow this, since the lack of natural light negatively affects the development of plants and the state of human health. After all, direct sunlight kills microorganisms.

How much tinted glass for windows reduces the intensity?

To prevent the development of bacteria and viruses in the premises, the tinting film for smart glass should be selected taking into account its light transmission.

The required level of insolation in living and working premises determines using special charts. They contain all the necessary information that will help you finds out the required time (+/-10 minutes) of exposure to direct sunlight.

 How much the value of real insolation should be more than the permissible minimum?

How to stick the film yourself?

To apply a polymer coating, you will need the following kit:

  • stationery knife with additional blades;
  • spray;
  • squeegee with rubber tip;
  • scraper for removing stubborn dirt from glass;

The search is for smart glass windows for installation on a balcony or loggia often ends with the choice of an average option – semi-warm glazing. Due to its practicality, it is in high demand. Semi-warm glazing of balconies is considered universal, as it is suitable for solving most repair and construction tasks.

What is semi-warm glazing of balconies?

When it comes to semi-warm glazing, they can mean 2 types of structures: sliding and standard with tilt-and-turn sashes. Both modifications of smart glass window blocks have fundamental differences, so you should not identify them. Each type of semi-warm glazing must be considered separately.

Both modifications are united by a common parameter – energy efficiency. It is not enough to equip a winter garden, a rest room or a study on the balcony.

At the same time, energy efficiency is sufficient to significantly reduce heat loss in the living room adjacent to the balcony. That is, the name of this type of glazing fully reflects its real capabilities.

Sliding system windows

This type of sliding smart glass windows is ideal for cramped balconies and loggias. Active sashes, when opened, are in the plane of the light opening and do not take up space inside the glazed room. These windows are easy to use and save space.


Along with the advantages of sliding systems, their 3 main disadvantages must also be taken in account:

Insufficient tightness – the way the sashes are opened provokes rapid wear of the seals, which can soon lead to smart glass window blowing;

Mosquito net with a sliding mechanism

Difficulties in the selection of accessories, for example, mosquito nets – due to the design of the windows, the use of a frame mosquito net becomes impossible. It is necessary to order a mosquito net with a sliding mechanism in order to avoid difficulties when opening / closing active doors.

This type of semi-warm smart glass glazing is preferable when space saving is more important than energy efficiency. In other cases, it is advisable to consider the option of installing standard window blocks.

Hinged windows require a lot of space

Standard units with tilt-and-turn sashes in the basic configuration have approximately the same energy efficiency with sliding models. But they do not wear out the sealing contours so quickly. In addition, window blocks of this type can insulate during operation.

The main disadvantage of such structures is that wide-open doors require a lot of space inside a cramped loggia or balcony.

Advantages of semi-warm glazing of balconies

The price of semi-warm glazing of balconies is slightly higher than the cost of smart glass PVC windows with the lowest level of energy efficiency. At the same time, such window blocks have 2 fundamental advantages:

  • help to save additional money on heating residential premises in winter;
  • Smart glassallows you to increase the energy efficiency of glazing at any convenient time (modernization work can be carried out even in the cold season).

In comparison with cold structures, semi-warm glazing has a higher rigidity, therefore it is better able to withstand wind and deformation loads.

How to make warm balcony glazing from semi-warm

The main heat leakage occurs through double-glazed windows, and not through frames and sashes. So, first of all, it is necessary to increase energy efficiency in these areas of window blocks.

Smart glass reduces heat loss, it will be necessary to replace conventional double-glazed windows with models with a selective coating. This will help to significantly reduce heat leakage.

The best option for modernization is the installation of new selective double-glazed smart glass windows with two internal chambers. You will also need additional insulation:

  • parapet;
  • floor;
