A form of glass in which a thin, tough layer of plastic is sealed between two sheets of glass. Laminated glass is used for car windscreens as a safety measure; when struck by the occupant in an accident, it bows out without puncturing, and the plastic holds the glass to prevent it from splintering. There are concerns however that the glass could trap an occupant following a crash.
Laminated glass is also becoming more popular in side windows as a security feature, as it can resist attack for longer than standard glass. It also helps to keep the cabin cool as it reduces the amount of sun coming in.
