Hollow glass as building energy-saving materials, 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. Convective transfer is due to the temperature difference between both sides of the glass with a hollow glass 595, causing the air in the cold side of the fall and rise on one side of the heat insulating glass roof, air convection 612a6 produce hollow glass, resulting in the loss of energy. The reasons for this phenomenon are a few: First, poor sealing glass and the surrounding frame system, causing gas inside and outside the window frame can be exchanged between convection, resulting in the loss of energy; hollow glass top | Yaohui glass trustworthy ( Online Consulting) | Jining hollow glass provided by Jinan Glass Co., Ltd.
