What AreThe Advantages Of Vacuum Glass?

vacuum glass

Energy saving

The U value can be as low as 0.4W/(㎡·K), and the thermal insulation effect of 8.3mm thick V glass exceeds that of a 1.5m thick brick wall.

The high-vacuum inner cavity of V-glass effectively blocks heat transfer, and its thermal insulation performance is 2-4 times that of insulating glass and 6-10 times that of single-piece glass. Its performance can reach nearly zero energy consumption in buildings and passive houses. , Curtain wall glass heat transfer coefficient requirements.


Reduce the use of air conditioning or heating, natural comfort, and stay away from sub-health;

Compared with the same area of ​​insulating glass, the energy consumption per unit building area is reduced by about 20%;

It is suitable for various types of materials, and it is easy to improve the comprehensive energy-saving effect of system doors and windows.


Ultra low dew point

The indoor and outdoor temperature difference is above 70 ℃ without condensation, which restores the original appearance of the curtain wall and window in the cold winter area.

Note: Test conditions Indoor temperature 25°C, outdoor temperature -50°C, relative humidity 70%.


Sound insulation and noise reduction

The weighted sound insulation exceeds 39dB, even in the downtown area, it is like being in a library.

The high-vacuum cavity of V-glass effectively blocks sound transmission, and its sound insulation effect is much better than that of insulating glass, especially for reducing medium and low frequency noise (such as traffic noise and construction noise) with strong penetrating power.

The life expectancy of tempered vacuum glass V glass can reach more than 25 years. It has a high vacuum inner cavity, so that the gas heat transfer can be ignored. At the same time, it adopts high-performance Low-E glass, which greatly reduces the radiation heat transfer and ensures the heat transfer coefficient (U value) of the V glass. ) as low as 0.4W/(㎡·K). At the same time, the thermal insulation performance of V glass is 2-4 times that of insulating glass, and 6-10 times that of single glass. It can meet the requirements of international passive house for heat transfer coefficient of doors and windows when used alone.
