Heat Strengthened Glass

Category: Tag:


Heat Strengthened glass is manufactured by controlling the tensile stress caused by heat treatment process within a certain range of temperature. The level of breakage from the outside impact is similar to that of annealed flat glass but strength coefficient is twice higher.

  • The strength and resistance to temperature changes of heat-strengthened glass is two times stronger than that of the annealed glass.
  • Heat strengthened glass has the same features of annealed glass like hardness, elongation, polarization, and resistance to etching.
  • Heat-strengthened glass has less distortions than tempered glass. Strengthening method improves the smoothness of processed reflective glass.
  • In comparison with the tempered glass, heat strengthened glass is not easily broken spontaneously.
