What Makes Laminated Glass Different from Other Types of Car Glass?

Laminated glass is distinct from other types of car glass due to its unique construction and safety features.

• Construction: Laminated glass consists of two or more layers of glass with an interlayer, usually made of polyvinyl butyral (PVB), sandwiched between them. This interlayer holds the glass layers together even when shattered, which is different from tempered glass that breaks into small, harmless pieces.
• Safety Features: The primary advantage of laminated glass is its ability to provide enhanced safety. In the event of a collision or an attempted break-in, the glass remains intact, reducing the risk of injury from sharp shards and preventing easy access to the vehicle’s interior.
