Intumescent Dampers

Intumescent Fire Dampers (IFDs) are designed to seal penetrations provided for movement of air via ducted or naturally ventilated means. Unlike mechanical dampers where the heat from a fire causes a fuseable link to break in the damper, the operation of the IFDs is by heat activation of the intumescent material. The intumescent swells many times its original thickness to form a solid barrier to fire.

  • Available in rectangular as well as round configurations, the fire dampers are suitable for incorporating into wall, floor and ceiling penetrations, as well as ducting.
  • Range of models with varying integrity fire ratings up to 4 hours.
  • No moving parts.
