Which feature describes laminated glass?

• A. A lamination of glass with no interlayer
• B. A thin plastic interlayer between two sheets of glass
• C. A single sheet of tempered glass
• D. Glass with metal reinforcement

Answer: (B)

Laminated glass is made by sandwiching a plastic interlayer between two sheets of glass. That interlayer, usually a clear polyvinyl butyral (PVB) or similar film, bonds the layers so that if the glass is broken the shards stay attached to the interlayer instead of flying apart. This containment reduces injury and helps keep the glazing in place, which is why laminated glass is widely used in windshields, skylights, and security glazing. A lamination with no interlayer wouldn’t bind the glass together, so it wouldn’t be laminated glass. A single sheet of tempered glass is strong but not bonded to another layer, and glass with metal reinforcement is a different construction, not laminated glass.
