Building Regulations impose limitations on all pipes
passing through fire compartment walls and floors.
Quelfire QIF Insulated Fire Sleeves allow pipes to meet
the requirements of the Building Regulations. Quelfire
QIF Insulated Fire Sleeves have been tested according to
BSEN 1366-3: 2009 where pipe diameters of up to
169mm have met insulation and integrity criteria for this
standard for up to four hours.


The Quelfire QIF Insulated Fire Sleeves consist 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.

Application / Installation

The Quelfire QIF Insulated Fire Sleeve should be placed around the pipe, positioned centrally within the partition and should protrude from each face of the wall by 50mm. 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 QIF Insulated Fire Sleeve, and any gaps should be sealed with the Quelfire GM Intumescent Acoustic Sealant.
