What is laminated glass made of?

Laminated glass consists of two layers of glass with a layer of plastic, typically polyvinyl butyral (PVB), sandwiched between them. This structure is designed to enhance safety and security; if the glass is shattered, the plastic layer holds the broken pieces together, preventing them from scattering and reducing the risk of injury. Additionally, laminated glass provides improved acoustic insulation and UV protection.

In contrast, the options highlighting a single layer of glass or a combination of glass and metal do not reflect the composite nature of laminated glass, which is inherently defined by the inclusion of the plastic interlayer that binds the two glass sheets together. The essential characteristic of this type of glass is that it is engineered for resilience and safety, making the described layering crucial to its function.
