Description

Fire Sleeve for Flue Pipes

Intumescent fire sleeve for flue pipes. Ideal for pipes and also flue pipes that pass through fire-rated block, brick, concrete or plasterboard. In the case of a fire, the intumescent material will expand, thus sealing the gap and preventing fire spread. 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.
•  They also absorb heat to help prevent services, pipes, and cables from overheating.
• Highly flexible, moisture resistant, and feature acoustic properties.
