PYRAN®

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.

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 life-saver when evacuating a building. Meanwhile, high light transmission along with excellent color 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. The SCHOTT PYRAN® Star range of fire-rated glass-ceramics have similarly impressive credentials.
