This glass has the appearance of a sandwich and is manufactured by joining two or more sheets with an interleaved film of polyvinyl butyral (PVB). PVB is a polymer composed of polyvinyl alcohol and butyraldehyde. This film offers a high range of protection against impact and / or penetration compared to simply tempered glass. In case of breakage, the PVB retains the glass fragments and prevents the broken parts from falling everywhere. It is a glass of excellent optical quality, low emissivity and solar control. Additionally, PVB provides a higher percentage of noise reduction.
