PYRAN® S Firman Glass – Now available for UK manufacture
Share
PYRAN ® S is a pre-stressed, monolithic borosilicate single pane safety glass in accordance with EN 13024-1. As a component in fire-resistant glazing that meets the requirements of resistance classes E 30, E 60, E 90 and E 120, it has proven its outstanding optical and mechanical charac teristics over the years in a wide variety of buildings.
Areas of application PYRAN® has been internationally approved and ideally suited for:
Facades
Partition walls
Skylights and rooflights
Doors
Roofs
Smoke screens
lift door glazing
lift shaft glazing
Facts
Higher ability to withstand temperature differentials: In comparison to soda-lime glass, tempered borosilicate glass can better withstand temperature differentials and can therefore be glazed with normal edge covers (20±2 mm).
Higher softening temperature: Because the glass is self supporting for more than 30 minutes, large panes and simple frame construc tions are now possible.
Higher viscosity: The glass flow rate is low due to the high viscosity and durability of borosilicate glass, so with more edge cover, grea ter fire resistance times in excess of 90 minutes can be achieved.
NiS crystals do not form: Due to the chemical composition of bo rosilicate glass, nickel sulphide crystals cannot form. Spontaneous glass fracture due to embedded NiS crystals cannot happen with PYRAN®
