Application - Installation Instructions

  • The Firesure™ metal intumescent duct sleeve must be positioned centrally to bridge the cavity within stud partitioning, so that as a minimum it is flush with both faces of the wall, or protrudes from each face. 

    The plasterboard should be cut to be as tight a fit as possible around the Firesure™ metal intumescent fire sleeve. Any gaps should be sealed with Firesure™ Intumescent Mastic.

     

    In a fire the intumescent expands and being contained within the metal sleeve it expands and closes the hole left by the collapsing ducting retaining the structures integrity.

     

    The Firesure™ metal intumescent duct sleeve is made to suit the size of the ducting and the length required.

     

    To ease installation of the Firesure™ metal intumescent duct sleeve a self adhesive tab is attached to secure the sleeve whilst positioning through the wall/partition.
