Low Profile Intumescent Duct Sleeve - 204 x 60mm

Intumescent low profile duct sleeves maintain the integrity of fire rated walls penetrated by plastic ventilation ducts.

The low profile duct sleeve is a more compact version of the standard duct sleeve that offers the same industry leading fire performance.

These 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. Furthermore to this, they have been assessed for use in series around multiple duct penetrations.

In the event of a fire, the intumescent material of the duct sleeve expands and crushes the plastic ventilation duct, closing off this route to the fire for up to 2 hours. Fire test evidence is available for use within 30, 60 and 120 minute wall constructions including a variety of single and double layer plasterboard partitions.

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.

The duct sleeves are available to fit common sizes of rectangular and circular plastic ventilation ducts.

Applications:

• CE marked.
• Compact duct sleeve with a fire rating of up to 2 hours - EN 1366-3 : 2009.
• Uncapped / Uncapped (Open | Open) fire tested as required for ventilation systems.
• Suitable for use through a wide range of fire partition walls.
• Reduced profile - 10-15mm thickness - allows installation at any position in the wall, even tight to the floor slab, without removing the top side.
• Does not need metal sleeving.
• Sleeve can be easily fitted and only requires access from one side.
• Sleeve can be slit to allow retrofitting.
