Envirograf Intumescent Wraps

Envirograf Product 7 wraps are foil-clad intumescent strips that are cut to length and wrapped around pipes or cables at a wall, floor or ceiling. Under heat the intumescent expands to crush PVC pipes and cables and seal the opening, while cooling steel pipes to stop them carrying heat through the compartment line.

• Ratings of 1, 3 or 4 hours depending on the depth of wrap used
• Stock references cover pipe diameters from 15mm to 600mm, with continuous rolls EWE1 and EWE2 for site-made sizes
• An acoustic version is available by adding the /A suffix, and a repair kit is listed for damaged seals
