A draft stopper is used with ceiling exhaust fans to stop air flowing in the reverse direction. It has a flap which automatically closes when the exhaust fan is off to minimise air leakage within the building envelope.
Made of moulded plastic, this draft stopper damper will sit on top of the exhaust fan in the ceiling/loft space.
