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. A label is supplied to adhere to treated pipes or cables, for identification
to the relevant authorities. See also Envirograf® Products 25 and 110 for cable and
pipe protection.
