Fire protection for ducting and ventilation systems which pass through fire-rated block, brick, concrete or plasterboard, both internally and externally. Specialised sleeves designed for electrical conduits are also available in this range.

In the case of a fire, the intumescent material will expand, thus sealing the gap and preventing firespread. They also absorb heat to help prevent services, pipes and cables from overheating.  Highly flexible, moisture resistant and feature acoustic properties.


– No more corrosion problems due to copper pipes having contact with concrete surfaces

– Meets all regulations

– Allows for expansion and contraction of hot pipes and gives up to four hours protection

– Easy to cut; no more sawing and de-burring steel pipes

– Can be cut with a knife and off-cuts can be taped together, leaving no waste

– Will last a lifetime in-situ and will not degrade or deteriorate

Cut out the hole with a powered hole cutter or padsaw and clean down edges.
