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.


– Used for fire-stopping gaps around cables and pipes from 15mm-600mm diameter as they pass through block and brickwork walls, floors or ceilings

– Will crush melting PVC or UPVC pipes/cables in a fire, filling the gap to prevent fire and smoke spreading
– Provides effective insulation for metal pipes, absorbing the heat from the pipe to prevent it from spreading through the structure
– 25mm wraps will provide 1 hour protection, 30mm wraps will provide 3 hours protection, 50mm and 100mm wraps will provide 3-4 hours
– Available in a continuous 10m roll which can be cut to size to fit services of practically any diameter
– Range also includes a repair kit which can be used to fill small openings around existing services, offering up to 2 hours fire resistance
– Materials will not degrade, lasting a lifetime in-situ

Application Instructions

Standard Wrap:

Wrap around the pipe or cable at the point where it passes through the wall, floor or ceiling
The attached adhesive strip is then used to fix both ends of the wrap together
Push the wrap into the hole around the service, leaving 10mm protruding from the wall face which can be pointed around as required

Continuous Wrap:

Wrap comes in a 10m roll and must be cut to size and applied in layers.
The 30mm wrap is for pipes from 15mm-200mm in diameter and should be applied as follows:
i. For pipes 15mm-65mm in diameter, adhere one layer to the pipe
ii. For pipes 75mm-127mm in diameter, adhere two layers to the pipe
iii. For pipes 160mm-200mm in diameter, adhere three layers to the pipe
The 50mm wrap is for pipes from 40mm-400mm in diameter and should be applied as follows:
i. For pipes 40mm-115mm in diameter, adhere one layer to the pipe
ii. For pipes 127mm-215mm in diameter, adhere two layers to the pipe
iii. For pipes 250mm-400mm in diameter, adhere three layers to the pipe
The wrap has an adhesive strip on one side, which is easily adhered to the pipe once cut to size
