How is a windshield typically made?

Windshields are typically made from laminated glass, which consists of two layers of glass with a layer of plastic in between them. This design provides several advantages: it enhances strength and stability, reduces shattering upon impact, and offers improved safety for occupants in the event of a collision. The laminated structure helps to hold the glass pieces together, minimizing the risk of injury from flying shards and providing protection against external elements.

In contrast, tempered glass, while it is stronger and shatters into small pieces when broken, is not commonly used for windshields due to its tendency to break in a way that could increase injury risk. Regular glass does not provide the necessary safety features for vehicle use, as it can easily break and cause serious harm to passengers. Polycarbonate, although tough and lightweight, is generally not used for windshields due to its susceptibility to scratching and its differing optical clarity compared to glass. Therefore, laminated glass is the preferred choice for windshields in vehicles, combining safety, durability, and clarity.
