Composition

The QWR Fire Collars consist of a continuous pressed stainless steel flexible shell containing high performance graphite based intumescent material which reacts under the influence of heat to exert pressure on the ventilation duct 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. The QWR Fire Collar has built in fixing lugs which are used to secure it to the structure.

Durability

Tested to Type X durability which means the QWR Fire Collars can be installed in conditions exposed to weathering. QWR Fire Collars are expected to last the lifetime of the building.

Application / installation


Quelfire QWR Fire Collars should be used where a plastic ventilation duct penetrates a fire rated floor/ceiling.

For vertical pipework, one unit should be installed to the underside of the floor.

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

The QWR Fire Collar should be fed around the plastic ventilation duct, 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 QWR Fire Collar must be secured to the floor/ceiling using fire resistant steel sleeve anchors.

Please refer to Quelfire Technical department for other technical fixing details.
