Vacuum glass is sealed around two flat glass, and then its gap into a vacuum, there is no air in the space, there is no heat conduction and convection, have the effect of super heat insulation, sound insulation. The gap between the glasses is usually 0.1mm-0.3mm.
Depending on the special structure of vacuum layer, vacuum glass can effectively block indoor and outdoor heat conduction. The heat transfer coefficient U value is below 0.6Wm-2k-1, and can be as low as 0.3W/(m·K), which is close to the wall. Can significantly reduce air conditioning power consumption and pollutants and greenhouse gas emissions, reduce environmental pollution.
Select the appropriate shading coefficient of vacuum glass, in summer, can effectively control the sun heat, keep the indoor cool; In winter, when the outdoor temperature is -20℃, the inner surface temperature of vacuum glass is only 3-5℃ lower than the indoor air temperature, which can keep the room warm and comfortable.
Easy noise reduction 42db, block the urban noisy environment, easily beyond the ordinary insulating glass installed in the urban noise environment of homes and workplaces.
Vacuum glass has super heat insulation performance. In cold winter, even if the outdoor temperature drops to -30℃, the temperature of the indoor glass surface is similar to the room temperature, much higher than the condensation temperature.
Vacuum glass is much thinner than hollow glass, which can save installation space and window frame materials. At the same time, because of the good thermal insulation performance, the anti condensation fog performance is also very good, can be removed from the window condensation fog caused by dew can not see the exterior and dew soaked windowsill, etc. Winter can reduce the feeling of cold in front of the window and the feeling of "surface wind" at the foot.
Vacuum glass is not easy to let the indoor warmth loss, but also does not conduct the cold outside, so the glass surface is not easy to cool, effectively prevent the generation of frost and water mist, prevent the rot of wooden Windows and the oxidation of aluminum frames, increase the durability and service life of window frames.
Vacuum glass blocks at least 99% of UV radiation, helping to reduce discoloration and aging of indoor furniture.
