_________ glass consists of two glass sheets bonded to a sheet of clear plastic sandwiched between them. Commonly used for windshields and rear windows.

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

Answer: (C)

Lamination describes glass built from two glass sheets with a clear plastic interlayer between them. That plastic layer, usually polyvinyl butyral (PVB), holds the glass together if it cracks, so the pane stays intact and visibility is preserved rather than producing dangerous, loose shards. This is what makes the glass a safety feature, especially for automotive windshields and rear windows where keeping the surface intact after impact is crucial. Tempered glass, by contrast, is strengthened by heat treatment and tends to crumble into small, blunt pieces rather than staying bonded together, which is not ideal for windshields. Float glass is simply the basic glass sheet produced by the float process and isn’t inherently laminated. The term safety glass covers laminated and tempered types, but the described structure—two glass sheets with a plastic interlayer—refers specifically to laminated glass.
