Multifunctional glass

The energy efficiency of the building depends on the quality of its glass cover. Buildings can save up to 40% on heating and up to 50% on air conditioning. It is multifunctional glass in combination with a warm aluminum profile and argon filling of a glass unit that copes with this task. ⠀

Ordinary glass in a double-glazed unit is responsible for light transmission, serves as a barrier to heat loss and protects premises from precipitation and wind. ⠀

The development of energy-saving glass with the finest deposition of reflective material (for example, high-grade silver) made it possible to achieve approximately twice the heat saving compared to ordinary glass due to the "clogging" of heat inside the room.⠀
⠀
The main problem of energy-saving glasses is their limited use for windows located on the sunny side of the building: since the heat did not go away, the room overheated in good weather. ⠀

Multifunctional glass is devoid of this drawback: in winter it reflects long-wave infrared radiation back into the room, keeping warm, and in summer it delays the entry of up to 2/3 of short-wave infrared radiation into the room, protecting the interior from the negative effects of ultraviolet radiation and overheating. ⠀
⠀
You might say to use bulk tinted colored glass. It is, of course, cheaper, but, contrary to popular belief, it has a higher absorption coefficient of solar energy compared to transparent. This means that it takes in more heat, which means that the room will heat up even faster. ⠀

In terms of the efficiency of reflection of sunlight with multifunctional glass, ordinary glass can be compared with a mirror sun-protection film. But it strongly distorts the colors outside the window, the windows themselves look unattractive with it, after a few years the film needs to be replaced and, moreover, in winter it does not retain heat in the room. ⠀
⠀
The magnetron deposition method makes the coating of multifunctional glass invisible to the naked eye: its thickness is only a few tens of nanometers. Spraying works during the entire service life of the window structure.

From the outside, the glass looks a little brighter than ordinary glass, as if it had just been washed. Ordinary glass transmits 88% of the light, multifunctional - 65%. The difference is in numbers, but this slight color distortion is invisible to the human eye.

There is a popular myth that silver plating has a positive effect on indoor climate. But this is not the case. Glass is installed in a glass unit by spraying inside, so it cannot have any influence - neither positive nor negative. Spraying protects from burning out of the leaves of indoor plants and reduces the rate of soil drainage.

The cost of a double-glazed unit with multifunctional glass, a warm spacer frame and argon filling does not exceed 15% of the base price on average. At the same time, the cost of its installation pays off in about two heating seasons.
