Schott TGS Pyran® S
Fire Resistant Glass
PYRAN® fire-resistant glazing is superior to conventional safety glass for a number of reasons. Made from borosilicate, it shows stronger resistance to a range of temperature differentials, which offers the potential for larger panes with longer fire resistance times and reduced fracturing.
- Higher temperature resistant – Superior ability to withstand temperature differentials
- Permanent transparency – Remains transparent even under high thermal loads
- High viscosity – The high viscosity of Pyran® results in low flow behaviour.
- Long resistance to temperature – Meets requirements of fire resistance times from 30 to 120 minutes.
- High softening temperature – Pyran® is self-supporting for over 30 minutes, enabling the production of large panes.
- No NiS crystals – Chemical composition prevents the formation of NiS crystals, eliminating spontaneous fractures. No need for heat soak test.
Life-saving light transmission
PYRAN® glazing retains outstanding transparency in extreme temperatures. This can be vital in the event of a fire, when visibility is challenged, and can be a lifesaver when evacuating a building. Meanwhile, high light transmission along with excellent colour reproduction mean that security can still be combined with attractive aesthetics.
Excellent technical specifications
The impressive technical qualities of PYRAN® are at the heart of its enduring appeal. The unique application of the float process to borosilicate glass creates a far superior product to conventional soda-lime glasses, offering an improved ability to withstand temperature differentials, higher softening temperatures, higher viscosity and reduced risk of fracture.
