Hollow glass is made of two or three pieces of glass, using high strength and high air tightness composite binder, the glass sheet and aluminum alloy frame containing desiccant bond, made of high efficiency sound insulation and heat insulation glass.

Reasonable configuration of insulating glass and reasonable thickness of insulating glass spacer can minimize the transmission of energy through radiation, thus reducing the loss of energy;The convection of the gas can be reduced, thus reducing the convection loss of energy.

The use of insulating glass can improve the safety performance of glass, in the case of using the same thickness of the original glass, the wind pressure strength of insulating glass is 1.5 times that of ordinary single glass.
