Fireplace dampers are inefficient due to warping and misalignment from frequent heating and cooling. A bad 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 blocker 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 chimney blocker to insulate your fireplace and save you money, heat, and comfort. This 24"X12" Chimney Balloon is designed to work on a chimney with maximum flue or damper dimensions of 24"x12". See image link above on how to measure your fireplace for a Chimney Balloon. Every fireplace and chimney is unique, don't be fooled by one size fits all solutions. The Chimney Balloon tucks away in the flue so it is not visible when installed. We list the most commons size Chimney Balloons on Amazon, but Chimney Balloons are available in hundreds of sizes.

Every Chimney Balloon also comes with a two-foot-long removable clear inflation tube that connects to the handle-valve to make inflation easy.
