Energy saving glass units

The principle of making an energy saving glass unit is in applying hard or soft coating on a surface of common glass (float) by technique of magnetic spraying. The transparency of such glass to visible light practically does not change as the spraying has a very thin layer. Manufactured by this technology, an energy saving glass unit with hard (k-glass) or soft (i-glass) coating works as a kind of thermal valve, it transmits over 75% of visible light and at the same time reflects more than 70% of thermal radiation back into a building. In summer, such coating reflects thermal (infrared) part of solar radiation. As a result, in winter, it gets warmer in a building, and in summer, it gets cooler, which helps to reduce energy consumption, both on heating and conditioning.

Low-emissivity glass with soft coating in its emissivity outperforms common glass in 21 times, glass with hard coating in 5 times.

Due to its thinnest, invisible energy saving coating a glass unit with thickness of only 44 mm keeps heat better than a wall with a thickness of 1 m and more, therefore there has been a tendency of increased use of big size energy saving glass units which gives in addition a larger flow of day light.

To enhance the function of heat preservation an energy saving glass unit can have a chamber filled with argon. This inert gas is characterized by high resistance to heat transfer and allows to save another 10-15% of heat. Therefore, for ensuring the best heat insulation, a glass unit with energy saving coating and inner filling of inert gas is ideal for that.

The formula of glass for energy saving glass units: (4-16-4i). (4-10-4-10-4i). (4-12-4-8-4i). (4-10Ar-4-10-4i).(4-10Ar-4-10Ar-4i)**

The advantages of energy saving glass units:

  • Allow to reduce to 70% heat losses from a building
  • Have high transmittance
  • Prevent condensate formation on glasses and their freezing
  • Keep warmth from heating appliances in winter
  • Protect from hot weather at summer time

Considering the fact that standards of energy saving and safety are constantly increasing, glass manufacturing and processing are in a continuous search for new technologies and innovations.
