Innovative, Flexible Fire Protection

Our PU28 fire barrier is a flexible alternative to traditional rigid fire board. Made from glass fabric PU coated material, PU28 is suitable for a range of applications including large building developments, timber framed constructions and smaller installations such as thatched roofs, partition walls, loft conversions or anywhere where building regulations specify a fire barrier.

Tested to BS476: Part 20 – Fire tests on building material and structures. Method for determination of the fire resistance of elements of construction (general principles).

The PU28 fire barrier provides passive fire protection with a high temperature treated glass fabric coating on both sides and a flame retardant polymer. Enhanced with mineral salts and vermiculite to increase performance. The PU coating suppresses irritant dusts.
