Flueblocker Chimney Flue Fireplace Draft Stopper, Herdwick Wool Chimney Damper Replacement, 8" x 20"

It's really good quality, nice thick wool. I had to cut a hole in the middle to fit over my flue blocker (which doesn't work) but it was easy to push into the slot and fit perfectly. I have no draft or hot air coming in at all. Would definitely recommend this.

Very easy to use. Very effective in stopping drafts and wind noise. Works so well I just ordered another for the other fireplace. Note that you should buy the handle extensions if you have a big fireplace.

works great. blocks drafts as advertised. the extension that they sell is a must if you have a large fireplace. the first one works so well I bought a second for my other fireplace.

Made in England, great quality and well worth the cost. My living room is noticeably warmer as a result!

Excellent product. Wish i would have purchased this years ago. Is your fireplace drafty? You should already own this!

It literally stops the air from coming in the house thru the fireplace.

I live in a 100-year-old house, and this is a GEM for sure, it completely stopped the draft and wow what a difference!

As described and instruction/illustration was helpful. The quality is good, but a little pricey. However, the prices have increased on most things. The size/fit can be adjusted/trimmed. It does block the chimney draft; immediately felt a difference. My first-time experience, but I figured out the proper installation for my chimney. The plastic installation arms/handle could be longer. Overall, a good purchase and would recommend.

This is extremely over priced for what it is. I will be returning it.
