Hollow glass is a glass product made of two or more pieces of glass with an aluminum frame filled with molecular adsorbent and separated by a certain width of space, and the aluminum alloy frame is sealed with butyl adhesive and then sealed with hollow glue or structural glue. It has good sound insulation, heat insulation, heat preservation, anti-condensation and other effects. It is widely used in curtain wall doors, indoor partitions or freezers of all kinds of buildings. The coating hollow has better performance.

Peculiarity

1. Sound insulation performance: insulating glass is an ideal noise reduction material, which can generally reduce noise by 30 decibels, and filling with inert gas can reduce about 5 decibels on the original basis.

2. Heat insulation performance: can effectively reduce the thermal coefficient u value, if filled with inert gas or coated glass, can further reduce the heat transfer coefficient.

3. Anti-condensation performance: Due to the filling of enough desiccant in the insulating glass interval strip, it can effectively adsorb the water vapor that may penetrate into the inner cavity and the outside world, ensuring that the air in the inner cavity of the insulating glass is absolutely dry. Therefore, it has good anti-condensation performance.
