Is the Car Windshield Tempered?

[IkerMarie]

Car windshields are classified as Class A laminated glass, Class B laminated glass, and zone-tempered glass. Below is relevant information about car windshields: 1. Introduction: Car windshield damage falls under separate glass breakage insurance, which covers compensation when the windshield or side windows break independently. General auto insurance typically requires comprehensive damage; if only the glass is broken, it won't be covered. 2. Causes of spontaneous cracking: Spontaneous cracking of car windshields usually occurs at the edges due to the heating and cooling process during laminated glass manufacturing. This creates internal tensile stress and surface compressive stress. When these forces are in balance, the glass remains stable; otherwise, spontaneous cracking may occur. If a car windshield is exposed to intense sunlight and then suddenly cooled with cold water, the extreme temperature variation may also cause the glass to shatter. If spontaneous cracking occurs, the driver should immediately pull over to the side of the road.
