RISK OF THERMAL SHOCK BREAKAGE

The temperature of a glazing unit alters with the temperature of its surrounding space. As the temperature rises, the system expands. This process poses no risks, as long as the temperature is maintained uniform throughout the pane’s surface. However, in case of uneven heat distribution, where part of the pane is heated (e.g. due to its exposure to the sun) while the rest remains colder (e.g. is shaded), the risk of breakage increases as dilation is impeded at the intersection between hot and cold.

At the point where significant differences in temperature are exhibited on a glass pane, tensions develop and when these tensions exceed certain limits, the glass pane shatters due to thermal shock.

The risk of thermal sock is mitigated by edge grinding and minimized through the use of thermally toughened (tempered) or heat strengthened glass. VAS GLASS offers a certified product portfolio that incorporates these treatments.

FACTORS THAT AFFECT THE RISK OF BREAKAGE

  • Energy absorption properties of the glass pane.
  • Climatic conditions.
  • Edge treatment (or lack of).
  • Size and width of the glass pane.
  • Edge coating materials.
  • Framing and installation.
  • Exterior shading.
  • Interior shading.
  • Positioning of heating/cooling equipment.
  • Permanent structures opposite of the glazing system.
  • Glass type used.
