Sandwich Glass

Laminated glass is made of two or more pieces of glass by pressing and heating one or more layers of polyvinyl butyral (PVB). Because the refractive rate of the PVB film  in the laminated glass is very close to the glass itself, laminated glass can maintain the same purity and transparency as ordinary glass. Laminated glass is a kind of safety glass. When the glass is broken, its fragments are still stuck on the PVB film, which can prevent accidents. By using different PVB films , our company can produce different types of laminated glass like anti ultraviolet, anti X-ray, anti electromagnetic wave and fire-proof.
