Laminated versus tempered auto glass?

All of the auto glass in your vehicle is manufactured to the reduce the likelihood of injury if it breaks and provides structural integrity to the design of the vehicle. There are two different types: laminated glass and tempered glass.

Windshields are made from a lamination process. A windshield actually consists of two pieces of glass, bonded together by a vinyl inter-layer. This vinyl layer cushions your head during impact. If a windshield breaks during impact, the broken pieces will generally adhere to the plastic lining.

Side and rear windows are made with tempered glass, which is produced by heating the glass to more than 1,100ºF and then rapidly cooling it. This results in the outside surfaces of the glass becoming harder than the center of glass and, therefore, is stronger than regular glass of the same thickness. If broken, tempered glass will break-up into very small pieces.
