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.
