The Fire Collar range is a popular solution to prevent the spread of fire by plastic ductwork through concrete walls and floors when you can not concrete in a sleeve  

Intumescent Fire Collars prevent the spread of fire, smoke and hot gases through plastic pipes which penetrate fire compartment walls and floors.

They contain 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.

Intumescent Fire Collars are suitable for any type of building where a fire compartment wall or floor is penetrated by plastic pipes.

They have built in fixing brackets which are used to secure it to the structure using the sleeve anchors supplied.

Technical Specification

Technical Specification


Marked Fire Collars should be used where a plastic pipe penetrates a fire rated wall or floor. For vertical pipework, one unit should be installed to the underside of the floor. For horizontal pipework one unit should be fitted to each side of the wall.

The soffit of the floor or the face of the wall must be smooth and where there are irregularities in the surface, the space between the flange of the unit and floor or the wall should be made good using Intumescent Acoustic Acrylic Sealant.

The  Fire Collar should be fed around the plastic pipe, securing the ends together by passing the tongues on one end through the slots on the other end. The tongues should then be bent back and the unit secured to the structure using the integral fixing lugs.

The Fire Collar must be secured to concrete and masonry construction using steel sleeve anchors. Where fitting to a plasterboard partition wall one Fire Collar should be installed on either side of the partition and fixed using through-bolts or steel hollow wall sleeve anchors.
