Which glass type is described as two sheets bonded to a clear plastic interlayer, used for windshields and rear windows?

• A. Laminated Glass
• B. Safety Glass
• C. Tempered Glass
• D. Float Glass

Answer: (B)

Laminated glass is made from two sheets of glass bonded together with a clear plastic interlayer, usually polyvinyl butyral (PVB). That interlayer binds the sheets so that, if the glass is struck, the shards stay largely in place rather than flying apart. This property makes it ideal for windshields and rear windows, where keeping the glass intact after impact enhances safety by reducing the chance of injury from sharp fragments and by helping the window hold its shape during a crash. In contrast, tempered glass is also a safety glass but it’s heat-treated to put compressive stress on the surface; when it breaks, it crumbles into small pieces rather than staying in one piece, and it doesn’t use a plastic interlayer. Float glass is just a basic flat sheet with no interlayer or specialized treatment. Safety glass is a broad category that includes both laminated and tempered glass, but the description with a plastic interlayer specifically identifies laminated glass.
