How is Tempered Safety Glass Made?
Our side and rear windows are made of tempered glass. Tempered glass is made by heating flat glass to approach its softening temperature and suddenly chilling with jets of cold air, which distributes compression stress on the glass surface as well as tensile stress in the center. The counteraction of compression stress and tensile stress provides tempered glass several times the strength of normal glass. When broken, tempered glass forms oblique bean-sized granules to reduce damage to vehicle occupants. Tempered glass also withstands rapid temperature changes.
