Passive house product
China's current building energy consumption is higher than 30% of the country's total energy consumption. More than 50% of building energy consumption is lost through doors and windows, and glass accounts for 70% of the window area. Our product testing shows that after replacing windows in wooden houses in North America with our tempered vacuum glass, you can save 32% on heating costs.

Passive room tempered vacuum glass
After the single piece of tempered vacuum glass is embedded in the wooden window, it is tested by the National Building Materials Testing Centre and fully meets the requirement that the K value of the passive room window is less than 0.8W/m2·K.
The tempered vacuum glass fully meets the requirements of national safety glass technology. It is used in passive green building. It does not need composite hollow glass or laminated glass. The window is lighter and thinner. It is flexible and easy to open and close. The window sash has a long service life and will not sag and deform due to excessive weight.
Non-tempered vacuum glass or semi-tempered vacuum glass must be made into vacuum hollow composite glass because it does not meet the requirements of national safety glass technology. The windows are easy to sag and the life of window frames and hardware is shortened.
