• Intumescent Metal Duct Collar - Fire Rated 4hrs

  • Intumescent Metal Duct Collars (Fire Rated for up to 4hrs) can be used where plastic ductwork penetrates fire compartment walls and floors to prevent the spread of smoke and fire.

    They consist of a continuous pressed stainless steel flexible shell which contains a graphite based intumescent material that reacts when exposed to heat to provide an effective insulation plug. This prevents smoke and fire passing through to the adjoining compartment. This collar has built in brackets for easy fixing.

    Tested according to BS 476: Part 20: 1987 to maintain fire resistance of up to 4 hours.
