What does the term "laminated glass" refer to?

The term "laminated glass" specifically refers to glass that is composed of multiple layers, typically two or more sheets of glass, which are bonded together with an interlayer made of a plastic material, usually polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). This construction method enhances the glass's strength and impact resistance, while also providing safety features; if the glass breaks, the interlayer holds the shards together, reducing the risk of injury. Laminated glass is often used in applications where safety and security are important, such as in automotive windshields and in buildings where enhanced resistance to breakage is desired.

Understanding the purpose and composition of laminated glass is crucial for its application in various contexts, such as architectural design and transportation, where safety and durability are prioritized. The other options do not accurately reflect the definition or primary characteristics of laminated glass; they pertain to different specifications or characteristics not unique to laminated structures.
