A cost effective product for fire stopping pipe penetrations, eg. plastic and metallic plumbing. Maintains similar thermal and acoustic properties as standard mineral fibre insulation to ensure compliance with water bye laws and building regulations for cold and hot water pipes and heating systems. In a fire the pipe sleeve sleeve expands to fill the available space between the pipe and the penetration.

In the case of a plastic pipe the sleeve will crush and close off the pipe as it forms a solid char, preventing the passage of fire and smoke.

All interested parties, designer, specifier, main contractor and specialist installers should provide access to allow the fire stopping seals to be regularly inspected and maintained, as well as records kept of such maintenance at minimum periods of 12 months, as required by the Regulatory Reform Order, and repaired if necessary. Reference should be made to ASFP TGD 17 – Code of Practice for the Installation and Inspection of Fire Stopping.


It is vital that those entrusted to design or install a fire stopping product have the necessary levels of competence to undertake the task professionally and thoroughly. The level of competency required will be commensurate with the expected complexity of the building. All designers must eliminate, reduce or control foreseeable risks that may arise during installation, construction or maintenance when preparing or modifying designs. Clients should ensure that the principal designer and principal contractor carry out their duties under CDM regulations. The ASFP foundation course in passive fire protection provides essential knowledge as part of demonstrating competency and understanding in this key fire protection specialism.
