Whats the difference between windshield glass and other window glass?
Auto glass is designed for optimum safety in the event of a crash. Windshields are made of laminated safety glass. Laminated safety glass is made from two pieces of glass with a layer of vinyl sandwiched in between. It will stay intact in a collision. The side and rear windows are made of tempered glass. Tempered glass has been treated to make it much stronger than other glass of the same thickness. If it breaks, it is designed to shatter into small pieces.
