The Chimney Balloon® is an inflatable fireplace blocker that prevents drafts from a chimney caused by a broken, warped, or missing flue damper. It stops heat loss by acting as a chimney plug draft stopper that air seals and insulates the fireplace. This saves you money and heat, and improves comfort.
The Chimney Balloon usually installs above the damper, but also works in chimneys that have no damper. You inflate it into the lowest spot in your flue that has at least two parallel walls, and is not obstructed with other hardware.
The 15″x15″ Chimney Balloon has a tapered edge that is designed to work on a 12” to 15” round chimney pipe, or a square chimney that is smaller than 15″x15″. The black handle-valve on the bottom of the Chimney Balloon is 7” long. Every Chimney Balloon also comes with a two-foot-long removable clear inflation tube that connects to the handle-valve to make inflation easy.
