ABSTRACT:
A device for stopping air leakage through fireplace flues includes an inflatable bag-like member having a top and a bottom of a flexible, air impermeable material. The top and the bottom are sealed together about an outer periphery of the member for retaining pressurized air therebetween. The member has a plurality of selectively slitable sealed areas for permitting a damper handle to pass through one of the areas. The top and the bottom are sealed together about each of the areas. A closable conduit communicates with the member for admitting pressurized air into the member.
