Firetherm Intusleeve, an intumescent steel sleeve for combustible pipes, providing up to 4 hours fire resistance for pipes passing through fire-rated walls and floors, and cavities in stud work walls.

The ultra-slim design of the Firetherm Intusleeve makes installation in tight or awkward areas and situations easier and less obtrusive than externally fitted fire collars, and are a great solution for angled pipes.

In a fire, the intumescent lining within the metal sleeve expands and crushes the heat softened plastic pipe, leaving a potential path for fire completely sealed.



Typical Configuration Types


  • Combustible pipes
  • Insulation types:
    • Rock fibre
    • Glass fibre
    • Phenolic
    • Nitrile rubbers

Tested In floors and walls, including lightweight partitions, and may also be used within Firetherm Intubatt 1 and 2.



Installation


  1. Pull open Intusleeve and fit around the pipe.
  2. Push Intusleeve through the compartment wall, ensuring equal overhang to each side.
  3. Close Intusleeve.
  4. Seal in place using Firetherm Intumastic or ADL sealant in gaps up to 20 mm. Larger openings may be sealed with Firetherm Intubatt.
  5. Annular spaces up to 60 mm may be packed using a minimum 60 mm depth 64 kg rock fibre.

The length of the sleeve is relative to the width of the wall and should be specified when placing an order.



Important


Building Regulations 2000 Approved Document B states that all plastic pipes over 40 mm should be provided with a proprietary sealing system which has been shown by tests to maintain the fire resistance of the wall, floor or cavity barrier. Firetherm Intusleeve complies with these requirements.



Fire Testing


Fully tested at Exova BM TRADA to 2 hours integrity and insulation walls. 4 hours integrity and insulation when used within Intucompound floor seals.

Tested at Exova BM Trada to BS EN 1366-3 and BS 476 Pt 20-22
