Fire Rated - Pyrobel | Fire Rated - Specification
Products - Fire Rated Glass    

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:

  • the integrity criterion, as the glazing will not collapse, nor let any flames, smoke or hot gases pass through.
  • 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.
 
 
 

Advantages
 
  • Pyrobel is a safety glass that meets the requirements of BS6206
  • Pyrobel provides a complete protection against fire – the integrity function ensures that the fire will not spread to adjacent rooms, stairs, floors or buildings;
  • 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.
