The new Low Profile Duct Sleeve is a more compact version of the original Astro DS Duct Sleeve and offers the same industry leading fire performance.
The Low Profile sleeves have been independently fire tested to BS EN 1366-3 in a full scale partition system with Uncapped/Uncapped pipe/duct end configuration as required for ventilation systems and assessed for use in series around multiple duct penetrations.
Low profile duct sleeves need no additional metal cage or sleeving, can be slit for retro fitting over ductwork and access is only required from one side.
The slim dimensions (typically 10-15mm thickness) and compressible nature of the intumescent material allows tight fitting against the ceiling soffit without the need to remove the top edge.
- Available to fit common sizes of rectangular and circular plastic ventilation ducts.
- Size: 103 mm diam. (internal height)

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.
