What You Need To Know About Auto Glass
Your windshield serves as the top safety restraint in your vehicle. It consists of two sheets of glass secured together with thick vinyl. When the glass breaks during an accident, the vinyl prevents it from falling into the car and injuring people.
The rear windshield (or back glass) serves a dual purpose. It is made of a different type of glass than the windshield to protect you and your passengers as well as provide integrity to the vehicle frame. The back, side, and vent windows, or quarter glass windows are made of tempered or “safety” glass. This type of glass is strengthened by thermal or chemical treatments to withstand blunt force. It will shatter into tiny cubes of glass instead of pointy shards that can cut or injure you and your passengers.
Side windows are also made of tempered “safety” glass. If the glass is subjected to enough force, this glass will explode outward because of the inner tension created by compression during the tempering process
