Performance
1.Optical performance:it depends on raw glass sheet and thickness.The range of it is Transmittance of solar spectrum 20-50%,Transmittance of visible light 10-80% reflection of heat radiation 20-80%.
2.Heat insulation:it is affected by the factors of raw glass sheet,thickness,airspace thickness.The heat exchange ratio can reach 1.6 W/㎡k that is only 1/2 compared to normal glass in case of low-e-glass used as raw glass.For the heat insulation,it would become higher along with more thickness of air space within certain range.
3.Sound insulation:general can reach 29-32 Db.
4.Resistance to frosting:in general case,frosting temperature on the surface of insulating glass inside room is about 15℃ lower than normal glass.
5 Dew point:it is lower than -40℃
6.Increasing area utilization for buildings:can reduce"unused area"near windows,so that can increase utilized area 2-4㎡.
Application
M
ainly used on architecture curtain wall for high grade builds,door and window for insulate heat and sound.
