Fire-Resistive Glass

May 2017

General Glass International has added Pyrobel fire-resistive glass along with PyroFrames™ and PyroDoors™ to their current fire-rated offering that includes fire-protective glazing products.
Pyrobel protects against the threat of deadly radiant heat from 45 minutes up to 2 hours. Its interlayer technology eliminates unsightly black spacers and secondary seals found in gel-filled units. This allows for virtually clear-edge butt-glazing similar to non-rated glazing. Pyrobel’s interlayers have about 40% less water content than gel interlayers, ensuring optical stability even at extreme temperatures down to
–40°F and up to 122°F. Exceptional sound reduction and light transmission performance makes Pyrobel the perfect choice for transparent wall assemblies separating busy corridors and gathering spaces from private offices and meeting rooms. Pyrobel is listed in both the USA and Canada by Intertek and UL in accordance with UL 263 and ASTM E 119 with hose stream.
PyroFrames™ are rated from 45 minutes up to 2 hours, while PyroDoors™ are rated from 20 to 90 minutes and limit temperature-rise to 2500 F at 30 minutes. Both offer the contemporary narrow sightlines typical of roll-formed steel profiles and maximum protection against the spread of radiant heat. Internal and external surface protection provided by Sendzimir galvanizing in combination with high-performance painted finishes ensures maximum lifetime durability. Pyro- Frames™ and PyroDoors™ are listed by Intertek in accordance with UL 263, UL 10C and ASTM E 119 with hose stream.
