With the national energy conservation policy more and more powerful implementation, building energy efficiency requirements have gradually increased. The construction of glass also appears to the high-performance, in the hollow built-in window blinds intermediate layer filled with argon, helium and other inert gas, which blinds are also more and more applications.
Inert gas relative to the air, the density is bigger, thermal conductivity is smaller, it can slow down the heat transfer of the middle layer to reduce the thermal conductivity of the gas, thereby reducing the hollow built-in louver glass heat transfer coefficient, help to improve the window blinds insulation performance and energy saving effect.
