Laminated glass consists of a interlayer made of Polyvinyl Butyral (PVB) bonded together between two panes of glass under heat and pressure. Once sealed together, the glass "sandwich" behaves as a single unit and looks like normal glass. Annealed, heat strengthened or tempered glass can be used to produce laminated glass. Similar to the glass in car windshields, laminated glass may crack upon impact, but the glass fragments tend to adhere to the plastic interlayer rather than falling free and potentially causing injury.
Laminated glass is the only glass to provide durability, high-performance and multi-functional benefits while at the same time preserving the aesthetic appearance of the glass. Laminated glass furnishes solutions to many architectural design problems and offers increased protection from the effects of disasters such as hurricane, earthquake and bomb blast.
Laminated glass is available in a standard range of PVB colours from a translucent white to transparent tints and solid opaque colours. For the architectural and interior design market, special coloured and decorative graphic interlayers (VANCEVA® Design Laminated Glass) can be introduced to encourage new design possibilities.
