Firoblok sleeves are designed to protect Cables and metal/Plastic pipes and ventilation Trunking passing through fire- rated ceilings, floors, or walls made from block, brick, or concrete, and hollow Plasterboard floors and walls. They are flexible, allowing contraction and expansion of water pipes, and give protection from corrosion caused by close contact with cement, cement blocks, Plaster, and other corrosive building materials.A silver coloured reinforced covering contains the intumescent material so that it expands inwards and crushes into melting PVC pipes, trunking, ducts, etc in the heat of a fire. They also absorb heat from fire and help prevent metal pipes, services, and armoured cables from overheating.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Firewise Supplies is consulted before specifying.
