The 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 QIF Insulated Fire Sleeve should be placed around the pipe, positioned centrally within the partition and should generally protrude from each face of the wall by 25mm, 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 QIF Insulated Fire Sleeve, and any gaps should be sealed with the QSS Intumescent Acrylic Acoustic Sealant.
