The side windows and rear windshield of a car are made of tempered glass. This type of glass is created by rapidly heating it to more than 1000 degrees Fahrenheit and then rapidly cooling it to room temperature. This process creates a compressive stress on the surface of the glass and an internal stress on its body, making it extremely strong and resilient to handle stress from external factors. When broken, tempered glass breaks into small pieces instead of long, sharp fragments, protecting people from causing injury. In addition to tempered glass, laminated glass is also used when building cars.
Laminated glass is composed of two sheets of glass placed together with a PVB (polyvinyl butyral) sheet between the layers. It is robust, thick and stable, and has higher impact, stress, and intrusion resistance than regular glass. Laminated glass is mainly used for windshields, while tempered glass is preferred for car doors or windows. The use of automotive glass in the manufacture of windshields, side windows and rear windows of automobiles has significantly improved safety in all parameters. An important difference between car or windshield glass and other glass is that the former is shatter proof.
Allstar Glass Corporation, proudly serving the greater Houston area since 1990, provides automotive glass services, including windshield repair, replacement or tinting. In conclusion, both tempered and laminated glasses are used in automobiles for different purposes. Tempered glass is mainly used for side window glass and rear windshield glass, while laminated glass is used for windshields. The use of automotive glass has significantly improved safety in all parameters.
