Product 110


Intumescent fire protection sleeves to protect cable baskets

£0.00 ex. Vat


Fire-rated cable basket

Fire-rated cable basket intumescent protection. Made of a fibre-free intumescent material which allows for the natural expansion and contraction of pipes and also gives protection from corrosion caused by contact with cement and other materials.

  • Ideal for services and cables which pass through fire-rated block, brick, concrete, or plasterboard.
  • Specialised sleeves designed for electrical conduits are also available in this range.

In the case of a fire, the intumescent material will expand, thus sealing the gap and preventing fire spread. They also absorb heat to help prevent services, pipes, and cables from overheating.  Highly flexible, moisture resistant, and feature acoustic properties.

Specially designed passive fire range to meet Document B of Building Regulations, and also tested to European Standards. Explore our further range of Firoblok Sleeves and Ducting Protection online now.
