Laminated glass is two or more lites (pieces) of glass permanently bonded together with one or more plastic interlayers (PVB : polyvinyl butyral film) using heat and pressure. Laminated glass can be broken, but the fragments will tend to adhere to the plastic layer and remain largely intact, reducing the risk of injury.
