Description

Use Envirograf Intumescent Coated Slabs to permanently fireproof walls, ceilings and floors in rooms where fire is a real risk, such as computer rooms. Also referred to as a Fire Batt, these high-density, 60mm thick rock-fibre fireproof slabs are easy to cut and fit around existing services such as pipes and wires, fireproofing for up to 4 hours and offering acoustic protection by impeding or absorbing sound.

Both faces of the fire slab are covered with intumescent anti-fire material which expands during fire to seal against smoke. The included intumenscent joining compound fixes the fire slabs/fire batts together, and the slabs can be over-painted and decorated.

Use in complete walls or large openings where the area needs to be extra strong due to ladders being leant against, etc, raised floors, and unsupported floors under 1m². A fire batt can also be used above door frames, between the head and ceiling.
