What makes automotive glass different from residential glass?

The basic difference in automotive glass is achieved after the glass is produced during what the industry refers to as the fabrication stage. During fabrication, automotive glass is processed through a series of steps that cut it to size, bend it to shape and add any necessary components to make the final product. In the case of a windshield, two pieces of glass are individually cut and shaped then joined together with a layer of plastic (PVB) between the pieces of glass to form a laminated product. The final strength of the windshield has many benefits that could not be achieved with only one layer of glass.

How does a windshield perform in an accident?

The windshield must break. When the windshield breaks, the glass must remain stuck to the PVB to minimize any cuts that would occur if an occupant were to come in contact with the windshield. The windshield must be able to stretch while absorbing the energy of the crash. This is why a soft flexible plastic layer is sandwiched between the two pieces of glass. The windshield must also keep you in the car during the entire accident. A windshield should not allow your head to penetrate through the glass. Finally, the windshield must remain attached to the vehicle opening. Windshields play a significant role and are very important for both frontal impact and rollover crashes.
