QIF Insulated Fire Sleeve prevents the spread of fi re where combustible (plastic) and non-combustible (metal) pipes penetrate fi re compartment walls and floors.

The QIF Insulated Fire Sleeves is supplied as a 300mm long sleeve and consists of a reinforced foil containing an insulating mineral fibre and graphite intumescent material which reacts under the influence of heat to exert pressure on the penetration.

As plastic pipes soften the intumescent forms a carbonaceous char, crushing the melting pipe and forming a plug, likewise, when used around non-combustible metal pipes, the intumescent will char around the pipe and prevent fire passing through to the adjoining compartment.

Installation:

The QIF Insulated Fire Sleeve can be used around both metal and plastic pipes.

QIF Insulated Fire Sleeve are suitable for use in concrete floors and various wall constructions including solid concrete masonry/block walls and flexible fire rated plasterboard partitions with and without QuelStop Fire Batt.

Fire ratings depend on the substrate and services so refer to the technical data and installation details for full details.

The QIF are primarily made from a mineral wool material so they will provide a degree of thermal insulation and thermal movement to the pipe as it passes through the fire compartment so no extra sleeves are required. Other pipe insulations can then be jointed onto the ends of the QIF once installed.

The QIF is approx. 25mm thick so holes should be cut or drilled at 50mm bigger than the Internal Diameter (ID) of the sleeve, refer to associated "Installation Instructions" document" for full details.

The QIF should be installed centrally within the substrate and although can be cut down in length must be either flush or protruding with a minimum required length depending on a number of factors so refer to the relevant documentation before commencing installation.

A set of installation details and an installation guide is available, however, installation of the QIF Insulated Fire Sleeve is simple, requiring no mechanical fixings and can be retrofitted around the pipe or simply slid on to the end like a sleeve during pipe installation.

To retrofit, the sleeve must be first cut along its length with a sharp knife, it can then be opened up and fed around the pipe where it must be then wrapped tight again and sealed with the self-adhesive foil tape that is provided with the QIF.

Provided the hole in the substrate has been drilled accurately, the QIF Insulated Fire Sleeve can then be slid along the pipe into position, ensuring that the minimum protrusions where required on both sides are achieved, and then finally sealed in place with QuelStop Intumescent Acrylic Sealant.
