Fire protection for ducting and ventilation systems that 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. Made of a fibre-free intumescent material which allows for the natural expansion and contraction of pipes and also gives protection from corrosion caused by contact with cement and other materials.

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