On average, 13 to 14 million windshields are manufactured or imported into the U.S. every year due to damaged windshields.

Laminated safety glass is used for windshields to reduce flying glass and occupant ejection from the vehicle in collisions. Windshields are secured to the vehicle body (pinch weld) using high-strength urethane adhesives. There are different types of urethane with different bonding and curing characteristics.
