Changes in the internal pressure of the air layer of insulating glass to make glass deformation 612a6 hollow glass, can cause image distortion, so in the altitude of 1000m or more use of hollow glass, the pressure of the air layer must be adjusted hollow glass explanation, when placing the order with glass supplier deliberations. 5 windows, insulation performance is closely related to the window frame material, you should choose good insulation properties window frame material. Such as for insulating glass ceiling lighting, interior side laminated glass should be used or explosion-proof film. Insulating glass insulating glass as a building energy-saving materials prices, because of its good thermal and acoustic insulation performance has been widely used. At the same time the quality of the insulating glass increasingly demanding. It is understood that the quality of the insulating glass biggest problem is condensation in the use of the air layer and the air layer condensation reason is that the dew point of the air layer during use is rising. Therefore, the dew point control insulating glass is the key to control insulating glass quality.
