Unlike regular windows, which are made from a single sheet of glass, windshields are made from laminated glass. This type of glass is made by sandwiching a layer of polyvinyl butyral (PVB) between two sheets of glass. This process creates a strong and durable material that is able to withstand impact and prevent shattering.

The reason why windshields are made from laminated glass is for safety. In the event of a collision or impact, the PVB layer in the windshield helps to hold the glass together, preventing it from shattering into sharp and dangerous pieces. This is especially important for the safety of the driver and passengers in the car, as it reduces the risk of injury from flying glass.

In addition to the laminated glass, windshields are also designed with a curved shape that helps to distribute the force of impact more evenly. This further reduces the likelihood of the glass shattering upon impact.

It's important to note that while windshields are designed to be strong and durable, they are not indestructible. They can still crack or chip from impact, and it's important to address any damage to the windshield as soon as possible to prevent it from compromising the safety of the vehicle.

In conclusion, the reason why windshields don't shatter like normal windows is due to their construction and design. The use of laminated glass and curved shape helps to make windshields strong and durable, while also prioritizing the safety of the driver and passengers. So the next time you're driving and a small rock hits your windshield, you can rest assured knowing that it's designed to protect you in the event of an impact.
