A complete unit giving fire and smoke protection to electrical and plumbing services passing through fire barrier walls made from block, brick, concrete, and hollow plasterboard. The system comprises three parts:
(A) A semi-flexible tube 200mm or 600mm long that can be cut to the right length to suit the floor or wall. In case of fire, this will intumesce and fill the hole, preventing the spread of fire.
(B) Two smoke protection units (one placed each side of the penetration) that allow the maintenance of services but, in a fire, prevent the spread of smoke. (See also Product 110).
