Double vacuum glazing with IR coating on two panes of glass to replace the brick wall thickness of 0.5-1 m. During the construction of a greenhouse or Conservatory of vacuum glazing, the energy consumption for heating reduced by 90%.
Vacuum glass is made according to the principle of a thermos.
To exclude the convective component of heat transfer through the glazing of this type, the vacuum level is adjusted to the technical. The vacuum gap between the glass is 40 microns. Glass thickness 4-5 mm. Flat glass soldered along the contour and narrow width of 0,8-1,0 mm and a thickness of 0.20 mm, a part of the solder glasses. Thus, the glass is a solder on the contour of the hollow spatial design, with high strength, which allows the use of such glazing standard glass thickness 4-5 mm.
Heat transfer in such a vacuum insulating glass units although it is present, but it is very small in comparison with ordinary glass. If you have the IR coating on the glass heat-transfer resistance may be increased by 10 times compared to single glazing, and comparable to a brick wall thickness of 0.5-1 m.
If a residential house has double glazing with glass thickness of 5 mm, while changing the glass on vacuum glazing with a thickness of 5-6 mm are used the same window frame. The insulating properties of the window will improve 5-10 times will be the same as a brick wall thickness of 0.5—1 m. This is the most economical method of increasing comfort in residential spacesas it does not require replacement of frames.
– double vacuum glass with IR coating on two panes of glass to replace the brick wall thickness of 0.5-1 m,
– in the construction of a greenhouse or Conservatory of vacuum glazing, the energy consumption for heating will decrease by 90%,
– vacuum Windows which gives space for the imagination of architects and builders. Imagine a normal warm house with brick walls with a thickness of 1 m, and the same warm house with a wall thickness of 10 mm, made of a vacuum double glazing,
– solar collector with vacuum glass heat the water to 60°C and 90°C, i.e. they are systems for hot water pass into the category installations for the heating of buildings.
