Chimney Balloon 12"x12" Inflatable Blocker (Medium Chimney Pillow

Fireplace dampers are inefficient due to warping and misalignment from frequent heating and cooling. A bad or missing damper can cost you up to 30% more on your heating bill. Your fireplace damper is releasing your indoor heat and letting in cold outside air! The Chimney Balloon® is a inflatable stopper that prevents drafts from a chimney caused by a broken, warped, or missing flue damper. It even works in chimneys that have no damper! The Chimney Balloon stops this heat loss by acting as a stopper to insulate your fireplace and save you money, heat, and comfort. This 12"X12" Chimney Balloon is designed to work on a chimney with maximum flue or damper dimensions of 12"x12". It can be used in either a square or a circular chimney.
