Windshield and Auto Glass Facts
Every part of a new car or truck comes from an OEM, (Original Equipment Manufacturer), including the windshield and other glass parts in your vehicle. The only 2 US automobile companies that actually make or made their own windshields are Ford and Chrysler.
Safety glass is used in all auto glass. Safety glass is manufactured to reduce the likelihood of personal injury when and if it should break. There are two different types which are called laminated and tempered glass. Windshields as well as some side and rear windows are made from a lamination process. This type of glass actually consists of two pieces of glass, bonded together by a "PVB" (polyvinyl butyrate) vinyl layer in between the two layers of glass.
In the event of an accident this vinyl layer serves several purposes, it cushions your head during impact, helps keep the vehicles occupants contained within the vehicle and also helps keep many small light weight foreign objects from entering the passenger compartment. If a windshield breaks, during impact, the majority of broken pieces will generally adhere to the plastic lining.
Tempered Glass The majority of car and truck side door and rear back glass windows manufactured consist of tempered glass which is produced with a process that involves heating the glass to more than 1,100°F and then rapidly cooling it. This results in the outside surfaces of the glass becoming harder than the center of glass which makes it stronger than regular annealed glass of the same thickness. If broken, tempered glass will break up into very small pieces which are less likely to cause as serious of an injury as annealed glass would.
Both an OEM and an OEE aftermarket windshield must comply with the same DOT and Federal Motor Vehicle Safety Standards
