Q: I have read about "Chimney Pillows" an inflatable fireplace draft stoppers in some government websites on energy. Is the chimney balloon what they are talking about? - TY
A: Hi TY, There are many different names for the Chimney Balloon. People call them Chimney bags, pillows, plugs, stoppers, seals, etc... So the reference you saw is probably talking about the Chimney Balloon. Here is a link to a page on the US Department of Energy website that talks of air sealing and the Chimney Balloon (see last bullet point): http://www1.eere.energy.gov/consumer/tips/air_leaks.html
The Chimney Balloon is often referred to as a "Chimney Pillow" so our company has trademarked that name as well. The unique feature of the Chimney Balloon is it is sized to fit your fireplace, it actually inserts into your chimney and inflates inside the chimney to seal it off with a tight wall to wall seal.
