Firoblok wall sleeves are made of a fibre-free intumescent material which, allows for the natural expansion and contraction of pipes and also gives protection against corrosion caused by contact with cement blocks, plaster or other materials. Available in 500mm lengths- these sleeves can be easily cut with a knife and the off cuts can be rejoined together with tape for further use.
The Firoblok fire sleeves are ideal for services that pass through fire rated block, brick, concrete, or plasterboard. End plates are also available to seal penetrations walls and floors giving services access to pass through. In the event of a fire, the intumescent material will expand sealing the pipe at either end and preventing fire spread. This product also absorbs heat to help prevent pipes, services and cables from overheating.
