The QWR CE Marked 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 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.
The QWR CE Marked Fire Collar has built in fixing lugs which are used to secure it to the structure.
Tested to Type X durability which means the QWR Fire Collars can be installed in conditions exposed to weathering. QWR CE Marked Fire Collars are expected to last the lifetime of the building.
