An intumescent fan cuff which prevents the spread of fire through ceilings where plastic ceiling fans penetrate the fire line plasterboard.
The CFC Ceiling Fan Cuffs consist of a continuous pressed stainless steel flexible shell containing a high-performance graphite based intumescent material which reacts under the influence of heat to exert pressure on the duct as it softens to form a carbonaceous char which provides an effective insulation plug thus preventing fire passing through to the adjoining compartment. The product has built-in spring clips which hold it to the plasterboard ceiling.
