**A Guide to Side Car Window Glass by USA Auto Glass** Side car window glass refers to the panels located on the sides of the vehicle within the doors. These windows come in various shapes and sizes and can be either sliding or stationary. Most modern vehicles are equipped with electric motors that control the movement of the side windows, allowing passengers to roll them up and down with a switch. In older cars, manual cranks were used to operate the windows, and only the driver and front passenger windows could be fully lowered into the door. **Types of Glass Used in Car Windows** Car and truck side windows are typically made of tempered glass, which is a type of safety glass. Tempered glass undergoes a specialized manufacturing process similar to that of rear windshields, making it highly durable and designed to break into small, harmless pieces upon impact. This reduces the risk of injury from sharp shards in the event of an accident or window breakage. **Benefits of Tempered Glass** Tempered glass is significantly stronger than regular glass, approximately four to five times more resistant to breakage. Its strength provides enhanced safety for both drivers and passengers in the event of a collision or window damage. **Tempering Process** During manufacturing, tempered glass undergoes a heat treatment followed by rapid cooling, creating internal tension and external compression. This process strengthens the glass and prevents it from breaking into hazardous sharp edges. **Side Car Window Replacement by USA Auto Glass** If your side car window is cracked or broken, consider professional window replacement services from USA Auto Glass.
