INTUMESCENT WRAPS
DESCRIPTION
Three types of very economical foil-clad Intumescent wraps for pipes and cables. A limited
range of acoustic protection versions is also available.

For use around pipes or cables in brick or block walls, and in concrete floors. Also for use with Products 4, 5, and 6, the wrap is pushed into the hole, leaving a 10mm gap back from the wall face for pointing with sand and cement or slab coating. The wraps will crush PVC pipes, trunking, and cables, and will cool steel pipes when attacked by fire – an economical way to protect services.
