Chimney Balloon 9-in W x 9-in L Plastic Chimney Damper Cb9x9

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.
