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 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
- 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.
- At night, the smart glasswindows cool down, which leads to a minimal reduction in the size of the glass?
- Due to daily expansion and contraction, the sealant layers on both sides of the spacer are gradually destroyed.
- There is an accelerated depressurization of double-glazed windows.
- 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:
