PYRAN ® S
For fire resistance and protection of people and property
Multifunctionality in fire protection
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
Now available for UK manufacture
• 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 selfsupporting 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 ®.
