HST: Performance

Performance

Thermally toughened HST glass:

• Is highly resistant to thermal stress. It can withstand differences in temperature of approximately 200°C
• Has a much higher level of mechanical strength and is more resistant to shocks than annealed glass. Thermally toughened HST glass is resistant to breakage due to bending of at least 120 N/mm²; for certain types of glasses, these values can be different (patterned glass 90 N/mm² and enamelled glass 75 N/mm²)
• Breaks into small, blunt pieces as per the relevant requirements. Thermally toughened HST glass is always a safety glass in certain applications. Its usage always depends on the application and local regulations
• Please contact your local supplier for the relevent classification
• Toughenable Magnetron coatings should be toughened to achieve the desired performance (fragmentation, optical, Ug value)
• The light, thermal and energy performance of thermally toughened glasses is exactly the same

Finishing

• Edge finishing Toughened HST glasses can be supplied with several edge finishings such as:
  • Arrissed edges
  • Ground edges but some bright areas permitted
  • Ground edges but no bright areas
  • Polished edges
  In buildings, toughened HST glasses will be delivered with arised edges as standard but depending on the type of application, other finishings can be supplied on request.
• Other possible finishings
  • Holes
  • Notches
  • Cutting
