Intusleeve Duct

A 140 to 300 mm (dependent on requirement) deep steel sleeve that is positioned around the ductwork. The device is pre-lined with a high expansion intumescent and is designed specifically to provide a low-cost solution for fire sealing combustible ducting penetrations whilst completely protecting the cavity within stud work walls. The device can be retro-fitted to existing ducting.

Features and benefits:

• Tested at Exova BM Trada to BS EN 1366-4, BS 476-20 and BS 476-22.

• Ultra-slim body design ensures easy installation in awkward situations.

• Fully tested for up to 120 minutes' integrity and insulation.

Applications:

Used to seal plastic ventilation ducts as they pass through fire compartment walls. In a fire, the intumescent lining within the metal sleeve expands and crushes the heat softened plastic pipe leaving a potential path for fire completely sealed.
