What type of glass strengthens a vehicle's body structure?

• A. Laminated
• B. Tempered
• C. Annealed
• D. Float

Answer: (B)

Glass that strengthens a vehicle’s body structure is laminated glass. The key feature is an interlayer, typically polyvinyl butyral (PVB), that binds two glass panes together. This interlayer helps the windshield act as a structural element, adding rigidity to the cabin and helping hold the roof and frame together during a crash or rollover.

Tempered glass, while very strong in bending, is designed to break into many small, blunt pieces and does not provide the same structural support as laminated glass; it’s used for side and rear windows for safety, not to reinforce the body. Annealed glass is a basic flat glass that can splinter into sharp shards, offering little safety or structural benefit. Float glass is simply a flat glass product and is not chosen for structural reinforcement in the vehicle.
