The tempered glass is subjected to a heat treatment to increase its resistance to mechanical and thermal stress. The glass is brought to a temperature of more than 600° C and then rapidly cooled. In case of breakage, the glass is fragmented into small, non-cutting pieces.
The tempered glass conserves the luminous and energetic properties of the base product. Once hardened they can no longer be cut or processed.
However, it is possible to assemble them in insulating glass.
