8"– 9" Round Chimney Flue Plug – Wool Draft Stopper for Fireplace and Wood Stove – Reusable Chimney Cover Insert, Draft Seal, Alternative to Inflatable Chimney Balloon

Let's just deal with the elephant in the room first - this thing seems stupid expensive for what it is. I mean, 50 bucks for a circle of fabric with a cheap plastic handle, wth? But I will say this: it works, bigtime, and for a tiny fraction of the cost of getting a chimney repairman to try to replace a leaky damper. The fabric circle is really a super-heavy-duty, all natural, woven sort of felt from, they claim, special sheep with really dense wool. I can't speak to that but I'll admit that I've never seen anything quite like it. Despite its thickness and solidity, though, it was not terribly difficult to trim up with heavy shears. Note: DO NOT attempt to make an exact fit! You want it to be a little big, so it'll squish into the flue and stay there from friction. I also had to cut a perpendicular slit to allow the damper control rod to pass through. This, too, was no big deal. And the result? Not only did all chimney drafts immediately cease, but the family noted a great improvement in allergies! Maybe pollen was blowing down the chimney along with the cold air? Or maybe they're allergic to whatever soot or ash the draft carried with it? Whatever - the cost of this gadget will pay for itself with a few less bottles of allergy meds, to say nothing of the cost of however much heat was vanishing up the flue. You do have to be a bit handy, detail-oriented, and flexible to crawl around upside down in your fireplace. Obviously make sure the fire is long out, and the fireplace is as clean as you can reasonably get it first. You're still going to get a bit dirty but it shouldn't be Dickensian. The results will be worth it.

Stumbled on this and tried it. Works very well to block the cold in my drafty fireplace. I highly recommend it.

Got 2 & they prevented smoke smell from my upstairs neighbor! Put one below in Flue and one on the top (roof) in Flue!

The concept here is simple enough - open the damper and stuff this nice insulated wool to stop the cold winter drafts. The sheep wool feels like great quality and it actually does make a significant difference in reducing the draft, but man $45 for some insulation on a stick is a tough pill to swallow. Unfortunately I couldn't find any alternative that looked comparable in the construction, so I suppose you get what you pay for, and in the grand scheme of things this lets me save money from my heating bill on a monthly basis so it probably pays for itself. Still though I feel like I had to do some mental gymnastics to justify the purchase.

If you have an older home and the flute cover doesn't seal well, then you may find this item as the right choice. For me personally it drastically cut down on the draft a great amount to the point I was no longer feeling any air draft coming from it. I did however buy a size larger then I needed but was able to cut it down to fit perfectly. So if you wanna save on your heating or a/c bill this is a great choice over using the ballon option as you don't need to be filling it up with air from time to time. The difference was immediately noticed.

Package came open. Missing the handle. Had to shove it into the flue opening without it. Seems to work decent. Wish I had the handle to shove it past the damper.

Great tool! The handle feels a little wimpy, but the wool pad is so thick. It really does help block the cold air from coming in. It is slightly larger than our flu pipe, but it squishes to fit. It seems like it is an awkward fit, but it does the job.

I was concerned about getting the right size and how this thing would work. I have a fireplace which I finally decided to switch to an electric log set. I did my best to measure the opening, but when I received the flue blocker, I realized that I may have ordered it slightly too large; however, it was not a problem. It just popped in and has stayed there undisturbed for six months now. I used to have cold air come down in the winter and hot air in the summer. Now there is nothing. I would highly recommend this product.

Bought the 10 inch version, the smaller 8 inch would have been better. The larger size bends sideways in the chimney flue and does not seal properly. It took a lot of adjustment to get it fitted correctly The chain could be a lot remind you it has been fitted

Fondamentale misurare il foro con precisione e scegliere la misura appena più grande in modo che si incastri. Arrivato, inserito, non si muove e chiude gli spifferi

I was struggling for long time to find a proper solution to stop wind draught coming from my fireplace and thank God I found this thing! It works brilliantly, completely stopped the draught even on a very windy and stormy day! House is so much warmer in the winter. Recommend!

Very effective and easy to use

simple, but it works
