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: 155 mm diam. (internal height)
