The Large Fireplace Plug is an inflatable urethane plug measuring 38" x 16". It is quickly and easily installed in the fireplace just below the damper level. The Fireplace Plug can be adapted to work in almost all fireplaces. Even if you have an unusual construction, the Fireplace Plug can be successfully installed in less than 2 minutes. The Fireplace Plug is provided with 5 "slittable" areas that can be cut to provide an opening for a damper handle. As the Plug is inflated it seals around the damper handle sealing the opening!

It stops so much cold air that I need to put my hand directly under it just to feel a difference in ambient temperature. This also means that it stops the fireplace odors that were entering the room. I've even tried it with the flue open and it still keeps the cold out.
It does not self-install: you have to take the time and be careful. I can now do it in about three minutes. Some words on installation:
- After you THINK you have installed it correctly, feel around all of the edges for leaks. When you feel a leak, simply push - or pull - that section of the balloon into the right spot to fully stop the leak.
- The balloon does give the impression of deflating, but this is a misnomer. In cold temperatures a balloon will shrink, not deflate, due to the air cooling in the balloon. This happened once, so far, to the point where cold air began infiltrating. All you need do is to inflate it a little, while the balloon is still in place (the long inflation tube makes it easy) and then check around the edges again as above.
Our room has been truly comfortable for the first winter in 15 years due to this. My only concern is it's ruggedness. If it does not puncture, it will pay for itself in about 2 years. I have been somewhat intentionally rough with it to test this and, so far, am impressed that it hasn't punctured.
UPDATE January 2010:
Have now been putting this in and out weekly for the second winter. Performs as well as new. Seems to be quite resistant to puncturing (and it's been pushed to the limit). If it were to puncture at this point, I would buy another one.
UPDATE January 2015: Still going strong! Seven winters.
Once I finally figured out the correct height and positioned the stand, I was able to inflate and block 99.9% of warm air entering our home. This will save a ton on our electric bill We have a gas fireplace with fake wood logs in the fireplace, I was able to slide the stand (plastic stick-like base) between the fake logs and it is hardly noticeable unless you are looking for it.
Anyone contemplating this, I suggest you go for it! Save your money and insulate your home.
I didn't cut any slits in this to accommodate the damper's lever, so I did have to shove a rag on either of the short sides of the chimney between the balloon and wall where it v-d, but it is perfect now. Love it. I'm sure the energy efficiency benefits are great, but for me, not smelling the creosote when it's wet out is the BEES KNEES.
Been in there for about 2 weeks, will update in a few months to see how it's holding up!
