If this intumescent pipe wrap is exposed to fire, it expands. As a result, the pipe it protects is compressed, and the hole it passes through is protected from fire for either two or four hours. (Duration determined by selected option at time of purchase.) The most popular 110 mm pipe wrap is kept in stock for immediate shipment.
Other sizes are available upon request. Tested and in compliance with both BS476 and EN1366-3. Approved by Certifire, LANTAC and NHBC. Pipe wrap will maintain integrity in frosty, moist and humid environments. Caution is advised during installation to avoid damage to the polythene cover.
