Verres traités thermiquement - Verres trempés
Like thermally toughened glass, heat-strengthened glass is treated using a method of controlled heating and cooling that locks the surface of the glass in a state of compression.
This method produces a glass with a bending resistance greater than that of annealed glass but less than that of thermally toughened glass since the glass is cooled more slowly.
Heat-strengthened glass does not require heat soaking
Many glasses in the AGC Glass Europe range can be heat-strengthened: clear or coloured Planibel, Stopsol, Sunergy, Imagin and so forth.>
Use: single glazing, insulating glazing, laminated glazing and so on-primarily for applications where:
- there is deemed to be too high a risk of the glass breaking due to thermal shock (particularly with solar control glasses or those with a higher level of energy absorption);
- the resistance of the glass to breakage by bending of a maximum of 70 N/mm² is considered sufficient.
Once treated, heat-strengthened glasses cannot be sawn, cut, drilled or processed.
