Description
Firoblok Fire Sleeves for Pipes
Firoblok fire sleeves for pipes, 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 pipe at either end and preventing firespread. They also absorb heat to help prevent services, pipes, and cables from overheating. Highly flexible, moisture resistant and feature acoustic properties.
