Superior safety glass

PYRAN® fire resistant glazing made of borosilicate is far superior to conventional safety glasses with a soda-lime composition:

High ability to withstand temperature differentials: Compared to other products, tempered borosilicate glass withstands temperature differentials much better and can thus be glazed with normal edge cover (15 ± 2 mm).

Higher softening temperature: Due to the fact that the glass is self-supporting for over 30 minutes, large panes and relatively basic frame constructions are now possible.

Higher viscosity: Due to the low flow behavior that results from the high viscosity of borosilicate glass, longer fire resistance times in excess of 90 minutes can be achieved with more edge cover.

No forming of NiS crystals: The chemical composition of borosilicate glass is such that NiS crystals are unable to form. This means a sudden fracture caused by embedded NiS crystals can be ruled out with PYRAN®.
