# Specifications: Pyrobelite 12

FIRE RATING: 60 MINUTES INTEGRITY/LOW RADIATION GLASS

### DESCRIPTION

Pyrobelite is a laminated glass assembled with clear intumescent interlayers. In the event of fire, the interlayer expands at around 120˚ C and transforms into a rigid and opaque fire shield, which enables the glazing to meet the integrity criterion of BS 476: Part 22: 1987 and to keep the heat radiation to a very low and safe level.
