Product Description

Firoblok fire sleeves for pipes & cables. Ideal for services or pipes which pass through fire-rated block, brick, concrete or plasterboard. Specialised sleeves designed for electrical conduits are also available in this range. End plates are also available to seal penetrations in walls or floors, allowing services to pass through.

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
