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
1/ WHY DOES HEAT STRENGHENED HAVE BETTER OPTICS?
Heat Strengthened glass have better optics because of lower temperature at processing which leads to less distortion on the glass.
2/ IS HEAT STRENGHENED GLASS BE SAFETY GLASS?
Heat-strengthened glass is not a safety glass product but it is suitable for security laminates.
3/ DOES HEAT STRENGHENED GLASS BREAKS SPONTANEOUSLY?
NO, heat strengthened glass does not breaks spontaneously.
4/ WHY HEAT STRENGHENED GLASS IS MORE SUITABLE FOR SECURITY LAMINATED GLASS?
Laminated glass resists intrusion because the inter-layer continues to safeguard the building even after the glass itself is broken. Security glass cannot be cut from only one side, so ordinary glass cutters are useless as break-in tools. Laminated glass tends to resist impact. In multiple configurations, it can even resists bullets, heavy objects, or small explosions. In most cases, it takes many blows, all in the same spot, to penetrate the glass.
