Laminated glass is created by sandwiching a durable plastic interlayer (usually polyvinyl butyral, or PVB) between two panes of strengthened glass. The glass and PVB are chemically bonded to one another during the manufacturing process, making it incredibly difficult to break.
Laminated glass doubles as a safety glass. When the glazing it struck, it breaks within the frame, but is held in place by the PVB.
Another important aspect of laminated glass is that additional layers of glass and PVB can be added during the manufacturing process. Once laminated glass reaches a certain thickness (around 5 cm or more) it becomes bullet proof, meeting UL752 bullet proof standards up to level 8 (the highest possible).
Laminated glass is usually comprised of two pieces of tempered glass with a layer of polyvinyl butyral, or PVB, sandwiched in the middle. This is true security glass that can resist blows from hammers, crowbars and even bullets if the PVB layer is thick enough.
