Intumescent Wraps

Economical, foil-clad intumescent wraps for pipes and cables. Easily cut to size and wrapped around any type of pipe or cable, providing an effective fire stopping barrier. Intumescent wraps fit into brick or block walls, and are also compatible with:

Intumescent Coated Slabs,

Non-Fibrous Slabs as well as

Fire Mortar.

Under intense heat, the intumescent expands, thus sealing off heat and fire and crushing PVC pipes, trunking and cables. Additionally, wraps will cool down steel pipes, preventing overheating. Alternatively, Firoblok Intumescent Sleeves or also Intumescent Protection Sleeves can be used for additional fire protection for pipes. A supply of labels should adhere to protected pipes or cables for identification to the relevant authorities.

Available in lengths between 250mm up to 650mm, or in a 10m continuous roll.  Simply cut to any size with a sharp blade. Alternative, limited acoustic wraps are also available in this range. Dependent on the size of wraps, fire ratings can range between 1 to 4 hours of fire protection. Suitable for use against floors and walls where services, cables or pipes pass through.

Fire barriers provide an effective solution for gaps or voids within buildings that require fire protection. Browse our full range of fire barrier products.
