Thermal insulation Anti- condensationSound insulationLighter and thinnerWider application Energy savingAbout vacuum insulating glassReasons for choosing
Vacuum insulating glass significantly improves the thermal insulation performance of windows, and greatly insulates the exchange of cold and hot air, and enables the indoor to maintain a comfortable temperature.
Thermal insulation
The thermal insulation performance of vacuum glass is 4-6 times that of Low-E insulating glass.
Sound insulation
The sound insulation capacity of hollow composite vacuum glass can reach 42dB, and the sound insulation performance can reach grade 5.
Anti-condensation
There is no gas between the two pieces of vacuum glass, which eliminates the possibility of internal condensation.
Wider application
It can keep its excellent performance (U value) unchanged in all positions of buildings, including facade, slope and roof; When it is used in plateau area, it will not appear crack phenomenon.
longer life
All the materials used are inorganic materials, which will not aging in the sun. The application of getter can ensure that the vacuum degree is constant within 25 years.
