Orient 6.38mm ~12.76mm Laminated Glass with PVB Film is made by good quality adhesive interlayer and advanced bond technology. Laminated Glass is a kind of glass made up of two or more sheets of top quality glass bonded together with a polyvinylbutyral (PVB) interlayer. After the PVB interlayer has been placed between the glass sheets, the whole assembly is subjected to heat and pressure. This makes the complete adhesion of the vinyl and the glass. In the event of breakage, the glass fragments remain bonded to the plastic interlayer.
