Intumescent sleeves to protect services passing through fire-rated ceilings, floors and walls
Firoblok sleeves are made of a fibre free intumescent material. Ideal for protecting cables, metal and plastic pipes, trunking and ventilation ducting where they pass through fire-rated block, brick, concrete or plasterboard. Also part of the range is a specialised sleeve designed for electrical conduits. End plates are also available to seal penetrations in walls or floors, allowing services to pass through.
– 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
Mark the outline for the Firoblok sleeve on the substrate.
Cut out the hole with a powered hole cutter or padsaw and clean down edges.
Fit the Firoblok sleeve over the vent and fit to the ducting or service passing through.
Push the assembly back into the substrate until flush.
