The thermal insulation performance is 4-6 times of that of insulating glass, which significantly improves the thermal insulation performance of doors and windows and insulates the exchange of cold and hot air between indoor and outdoor.

The vacuum state is between the two pieces of vacuum glass, there is no gas, and the possibility of internal condensation is eliminated.

The vacuum layer effectively insulates the sound transmission, and the maximum sound insulation of the composite vacuum glass can reach 42db. Vacuum glass is the best choice to solve the life noise.

The thickness of the vacuum glass is only 8-10 mm. For the reconstruction of the old window, the glass can be directly replaced without changing the window frame.

It can keep its excellent performance (k 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.

Because of the vacuum glass greatly isolated the heat transfer from the inside and outside, it can significantly reduce the heating cost and save energy.
