Thermally Tempered Glass or Toughened Glass

Visiontek Systems offer a range of thermally tempered or toughened glass

  • At least two and a half times as strong as traditionally tempered glass· Five times as strong as un-tempered glass
  • It can be ground, drilled and cut without any risk of breakage
  • Thermally tempered glass, when laminated, will have a localized break pattern for better visibility


Minimum thickness 3.0mm


How to improve the resistance of your glass by thermal tempering ?


Advantages of tempered glass

  • 2 to 5 times more impact resistant than un-tempered glass
  • High resistance to thermal stress
  • When it breaks, the glass bursts into multiple pieces with very few sharp parts
  • Verre Industrie applies the current standards of safety glass
    • BUILDING: EN12150
    • RAILWAY: NFF31129
    • LIGHTING: EN60598



Manufacturing process for tempered glass

  • Glass cutting & processing needs to be done before tempering
  • Heating: passing the glass through an oven to bring it close to its softening point (+/- 600°C depending on the type of glass)e
  • Tempering: sudden and rapid surface cooling thanks to air jets, creating antagonistic forces between the core and the glass surface and thus making it more resistant.  
  • Cooling: during complete cooling, the core of the glass will not be able to contract as much as it wishes and therefore expands, the skins in reaction will be in compression.


Applications of tempered glass

Tempered glass is used in many industries

  • Transport
  • Electronics
  • Industrial equipment
  • Lighting
  • Urban furniture
  • Building



Hardening control with fragmentation test :
the quality of the hardening is checked on every batch by a breakage test
