Fire Metal Sleeve for Ducting

The fire 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 metal intumescent fire sleeve. Any gaps should be sealed with 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 metal intumescent duct sleeve is made to suit the size of the ducting and the length required.

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