Tempered Glass

Tempered Glass

Tempered glass has its strength resistance built from going through a process called tempering. This process consists of heating the glass intensely in a special tempered oven then cooling down with a special procedure that quickly cools down the glass subjecting the material to a tension system. This causes the glass to become more resistant because glass has excellent resistance to compression and little resistance to traction.

PKO do Brasil’s tempered glass is produced with the use of horizontal tempering furnaces, with the use of modern machines that results in no clamp marks on the glass surfaces, and the ability to manufacture large sheet sizes while keeping the glass thin.

The company complies with the ABNT NBR 14698 to produce tempered glass, which goes through extensive tests to ensure its quality, in addition we are certified by Inmetro [“Instituto Nacional de Metrologia, Qualidade e Tecnologia” – “Brazilian National Institute of Metrology, Quality and Technology”] seal.

Benefits of Tempered Glass

  • Five times more resistant than standard glass with the same thickness.
  • Upon breakage, the entire plate shatters into small pieces with minimum cutting edges, providing users with more safety.
  • Because it is more resistant, it can be applied as a self-supporting structure, with minimum use of support profiles, and can also be installed with fittings.
  • More resistant to temperature fluctuations.
