Fire Rated Glass - Pryobel
Fire Rated - Pyrobel | Fire Rated - Specification
Pyrobel is a multi-laminated glass assembled with clear intumescent interlayers. In case of fire, these interlayers expand at around 120oC and transform into a rigid and opaque shield. Once formed, this opaque shield enables the glazing to meet:

01. The integrity criterion, as the glazing will not collapse, nor let any flames, smoke or hot gases pass through.
02. The insulation criterion, as no radiant nor conductive heat is transmitted.
Applications
Pyrobel can be used in all applications where building regulations stipulate a specific level of fire resistance and where natural light and clear visibility are required.
Fire
Advantages - Toughening
  1. Pyrobel is a safety glass that meets the requirements of BS6206
  2. Pyrobel provides a complete protection against fire – the integrity function ensures that the fire will not spread to adjacent rooms, stairs, floors or buildings;
  3. The insulation function avoids the danger or combustible materials being ignited on the protected side and ensures a safe and panic-free evacuation as people will not see any flames nor feel any heat.
