Intumescent Wraps

Description

This range comprises three types of very economical foil-clad intumescent wraps for pipes and cables. 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 seal the void around PVC pipes and cables, and cool steel pipes when attacked by fire – an economical way to protect services. A label is supplied to adhere to treated pipes or cables for identification to the relevant authorities. See also Envirograf® Products 25 & 110 for cable and pipe protection. The products offer up to 4 hours’ protection. Please state the required protection period when ordering.

ADVANTAGES

• Available in a continuous 10m roll which can be cut to size to fit services of practically any diameter
