Heat strengthened glass is a semi tempered glass which has been strengthened thermally by inducing a surface compression of 6000 to 9000 psi as compared to a range of 11000 to 20000 psi in case of fully tempered glass. It is two times stronger than annealed glass. Though it is not considered to be a safety glass it is widely used on building facades due to better optics.
