Pyran S Monolithic Fire-Rated Glass
Passive Fire Protection


PYRAN® S is a pre-stressed, monolithic, borosilicate single-pane safety glass for use in fire resistant glazing for protection against the spread of fire, hot gases and smoke. The unique combination of borosilicate glass manufactured in a micro float facility results in glass with outstanding properties.

Available thicknesses: 5mm, 6mm, 8mm, 10mm, 12mm

PYRAN® S is designed for applications where maximum safety is required without compromising on aesthetics and is ideally suited for use in facades, partition walls, skylights, roof lights, doors, roofs, smoke screens, lift door glazing and lift shaft glazing.

The glass has outstanding physical properties which allow for the construction of large panes of glass with longer durations of fire resistance achieved with only basic frame constructions and normal edge covers.
