Summary

At a glance

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®.

Proven and safe

PYRAN® remains transparent, even under high thermal loads. This ensures vital insight in the case of a fire and makes it much easier to evacuate a burning building safely. Excellent color reproduction and high transmission in the visible and UV range ensure that this increase in security is not achieved at the expense of appearance. It is certainly no coincidence that PYRAN® has been proving itself in airports, hospitals, hotels, industrial buildings, museums, offices, schools, shopping centers, sports facilities and even on cruise ships for decades.
