Windows
Car windows are the transparent panels located on the doors and sides of a vehicle, designed to provide visibility and ventilation for the driver and passengers. Unlike the windshield, most side and rear windows are made of tempered safety glass, which is specially treated to be significantly stronger than standard glass. If it does break, it is engineered to shatter into small, dull-edged granules rather than sharp shards, reducing the risk of serious injury during a collision. The primary function of these windows is to balance cabin comfort with safety and security. Most side windows are mounted on a mechanical or electrical regulator that allows them to be lowered into the door frame, providing fresh air and a way to communicate with people outside the vehicle. When closed, they create a weather-tight seal that protects the interior from rain, wind, and road noise, while also acting as a barrier against theft and unauthorized entry. In modern vehicles, windows often incorporate advanced technology to enhance the driving experience. This includes solar-reflective coatings to block UV rays and keep the cabin cool, as well as factory-applied privacy tints on the rear glass. Many luxury or electric vehicles now use "acoustic glass"—a dual-pane laminated design similar to a windshield—to further isolate the cabin from outside sound, while power windows often feature one-touch operation and "anti-pinch" sensors to prevent the glass from closing on an obstruction
