Intumescent Fire Blockers provide protection against the spread of fire and hot smoke through doors, walls and ductwork. They differ from regular fire dampers in that they have no moving parts; instead they expand to many times their normal size upon exposure to elevated temperatures indicative of a fire, forming an incombustible mass which seals its aperture, preventing the spread of fire and hot smoke.
