QIF Insulated Fire Sleeve

Insulated fire sleeves to prevent the spread of fire through combustible and non-combustible pipes where they penetrate fire compartment walls and floors.

Consists of a foil containing insulating mineral fibre and graphite intumescent material which reacts under the influence of heat to exert pressure on the pipe as it softens to form a carbonaceous char, which provides an effective insulation plug, thus preventing smoke and fire passing through to the adjoining compartment.

Features and benefits:

• Suitable for masonry or plasterboard partitions.

• Available for 17–169 mm pipes.

• Can be retrofitted.

• Manufactured in the UK.

Standards and approvals:

• Up to four hour fire rating.

• Tested to BS EN 1366-3: 2009.

Application/ installation:

The sleeve should be placed around the pipe, positioned centrally within the partition and should generally protrude from each face of the wall by 25 mm, depending on the thickness of the partition. To retrofit, the sleeve must be cut along its length with a sharp knife put around the pipe and then sealed with the foil tape provided. The plasterboard should be cut to a tight fit around the sleeve, and any gaps should be sealed with QuelStop Acrylic Sealant (specified separately).
