Laminated glass is a type of safety glass that is commonly used in automotive windshields. It is made by sandwiching a layer of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA) between two layers of glass. The PVB or EVA layer acts as an adhesive and a cushion, holding the glass together in the event of an impact. This construction provides several benefits:

• Safety: When laminated glass shatters, it tends to hold together rather than breaking into sharp pieces. This reduces the risk of injury to passengers in the event of an accident.
• Security: The interlayer makes laminated glass more difficult to penetrate compared to regular glass, offering better protection against break-ins and theft.
• Noise reduction: The PVB or EVA layer provides sound insulation, resulting in a quieter ride by reducing the intrusion of outside noise into the cabin.
• UV protection: Laminated glass can block up to 99% of harmful UV rays, protecting passengers from sun exposure and preventing the vehicle’s interior from fading and deteriorating over time.

These properties make laminated glass an ideal choice for windshields and other critical areas of a vehicle where safety and security are paramount.
