Tempered glazing

  • Tempered glazing is simply designated by its thickness in mm.
  • The tempering process has the effect of improving bending strength and thermal shock resistance. In the event of impact, the glass breaks into small, relatively blunt pieces.
  • As soon as glazing has been mechanically fixed, clamped, drilled, with notches, it should be tempered. 
  • Tempered glazing can be given an additional treatment called HST.
  • CEKAL certification focuses on the quality of heat soaking (fragmentation, surface stress, etc).
