Intumescent fire collars to prevent the spread of fire through plastic ventilation ducts where they penetrate fire compartment floors.
Intumescent fire collars to prevent the spread of fire through plastic ventilation ducts where they penetrate fire compartment floors.
Consists 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 collar has built-in fixing lugs which are used to secure it to the structure.
