The windshields of cars are made of laminated safety glass, which is a combination of two pieces of glass and a thin layer of vinyl between them. This type of glass is designed to offer the highest levels of safety in the event of an accident. It is also known as automatic glass, and it is either tempered or laminated. Tempered glass is used for the rear window and the front and rear door windows, while laminated glass is used for the windshield.
Laminated glass is created by bonding several layers of glass together under pressure and heat, with a resin called polyvinyl butyral (PVB). Safety glass is treated to reduce the likelihood of injury if broken. It can be repaired, but tempered glass breaks completely in an accident and requires a complete replacement. Automotive glass is also used for sunroofs; they are designed to be UV-resistant to help passengers enjoy natural light without harmful UV rays.
There are three types of windshield glass that can be used in your vehicle: dealer glass, aftermarket glass, and original equipment manufacturer (OEM) glass. Dealer glass is made by the same manufacturer as the original glass, while aftermarket automotive glass comes from the OEM but was created on a different production line. Automotive glass is exceptionally durable and responsible for 60% of the car's structural integrity in rollover accidents, while absorbing 45% of the impact of the accident during a head-on collision. It meets original safety and quality specifications such as factory glass, and it can serve multiple purposes depending on consumer requirements.
