Laminated glass is a composite glass product consisting of two or more pieces of glass with one or more layers of organic polymer intermediate film between them. After special high-temperature pre-pressing (or vacuum) and high-temperature and high-pressure processing, the laminated glass and intermediate film are bonded together.


Hollow glass is between glass and glass, leaving a certain gap. The two pieces of glass are separated by effective sealing material and spacer material, and there is a desiccant to absorb water between the two pieces of glass, thus ensuring that the interior of the hollow glass is a dry air layer for a long time without water and dust.


Even if the laminated glass is broken, the fragments will be adhered to the film, and the surface of the broken glass will remain clean and smooth. This effectively prevents fragments piercing and penetrating falling events, and ensures personal safety, so laminated glass is safer.


Sandwich glass has transparent, high mechanical strength, light resistance, heat resistance, cold resistance, sound insulation and ultraviolet protection. Sandwich glass has good impact resistance and safety when broken. Sandwich glass can also be made into hollow glass.


Hollow glass has good thermal insulation, heat insulation, sound insulation and other properties. If the glass is filled with various diffuse light materials or dielectrics, better effects of sound control, light control and heat insulation can be obtained.
