Which glass type is commonly used for windshields and rear windows?

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

Answer: (A)

Safety glass is designed to protect occupants by breaking in a safer way or staying together when a window is damaged, which is especially important for vehicle glazing. For windshields, the glass is typically laminated safety glass, meaning two layers of glass bonded with an interlayer that holds the shards in place and maintains the barrier even if the surface is cracked. This helps protect occupants, maintain visibility, and support airbags during an impact. Rear windows also use safety glass to limit injury if the glass is struck or broken, with tempered glass often chosen for its tendency to break into small, blunt pieces, while laminated forms are used where extra retention is needed. In short, safety glass covers the types used for both windshields and rear windows because the design focuses on reducing injury and preserving the window’s integrity after damage.
