Flueblocker for 13"x35" Chimney - Draft Stopper Wool Fireplace Plug

Standing next to my fireplace I could feel a draft. I checked around on line and came across this. I did call the company to talk to them about what size would be best and would something like this work on my fireplace. Customer service was great. Mr. Raddenbach got back to me within the hour. I emailed a picture of what I had. (you can see by the photo looking up my chimney.) We decided on a 8x32 Flueblocker. It arrived earlier than it said it would. I took a picture with a thermal camera before I placed it in to get an idea of what was going on. (you can see by the photo the chimney is cold, purple shows cold, inside and out. (( yellow orange are warmer temps.)) Yes it was Christmas time when I did the first photo, so there is a couple of Christmas decorations around it. When I received the Flueblocker I inserted the pad through the damper frame and pull it back to make a seal. I figured I would give it 2 days to make sure its working. (also gave me a chance to start taking down my Christmas decorations.) As you can see by the other photo the fireplace it warmer, a lot more yellow and orange. The draft I felt to start all this was gone. My fireplace is not used for burning anything right now. When the time comes that I use it to burn wood I will remove the blocked. This Flueblocker is great, 10 seconds and down. Mine came with 2 screw in poles to help with making the seal. When down unscrew the poles and place aside for when every you wish to take it out and use your fireplace..

Completely stopped the odors/air coming from my fireplace. It was incredibly easy to set up and has adjustable length handles depending on how far you are going to insert into the chimney. No other solution I looked up was going to work, so I’m really glad this option existed.

We started to get “fireplace smell” in our family room when using the exhaust fan in the kitchen and when the air conditioning started running (and pulling air through the returns). We had a traditional damper that was of course not airtight at all, and started to look for a solution. This product seemed easiest to use and most sensible versus the balloon type plugs. It did require removing the metal door damper and replacing it with this. Initially, the results were not great — it was only a little better and we were still getting smell. So I called their customer service and the person there was genuinely helpful. Had me send a photo of my situation, and he advised me on a way to sort of cross tuck the corners (difficult to explain) in a way that it greatly tightens the fit of the blocker. That seemed to help, because after that there has been a significant reduction in the smell (though not full elimination). That said, I agree with some of the other reviews - for what this essentially is (i.e., a thick piece of wool), it’s rather overpriced. However, for whatever reason, there seems to be only 1 manufacturer/distributor of this product so they’ve got the market cornered.

Not the cheapest solution, but I believe that this will last a really long time. It absolutely has blocked all the smells that were coming back into the house when the weather outside got warmer. The energy savings will be a bonus. It fits perfectly without the need for trimming. Make sure you size it up from your opening. I am looking forward to using my fireplace again next year without the dread of dealing with the nasty smells.

I have to say, I was ready to send this product back ($70 for some wool?!), but I'm so glad I ordered it! It took about five minutes to correctly install in my unused chimney, which has been sending cold air down into the family room for years. The downdrafts have been eliminated completely—so much so that I actually uttered an expression of surprise (that Amazon won't print, so I won't repeat) when I ran my hand along the edges to feel for any cold air. Highly recommended! (I did have to do some additional sealing in the two of the corners, which I did by cutting up an old cotton mop pad; perhaps the company could include a few extra pieces of wool in the package?)

We looked into a mason to fix and replace our missing flue damper. That was going to cost thousands of dollars and make a huge mess. Then we got a bird in our house along with the winter drafts--something needed to be done ASAP. Looked into Styrofoam to wedge up there but then the Flue Blocker came up on my search. I wasn't sure what size to buy, they weren't exactly the size of my flue. I went slightly bigger than our opening and very glad I did! It fits perfectly and gives a tight seal--the sides conform and wedge into the walls of the chimney opening. The sides are flexible and form a tight seal being a little bigger. We take the flue block in and out almost every day with very much ease as we light the fireplace. There are no more drafts or birds. The price was a little more than I thought it should be before I purchased, but once I got this (a) it solved a big problem, (b) it is very durable and (c) very high quality - natural product. Worth every penny and this is not a sponsored post--I am just a happy customer and surprised how good this worked!

His is NOT WORTH IT AT ALL. It does not work, is hard to fit, overly bulky and falls out and WAY too expensive. I bought one, and wish I could get my $160 back. 12 inch insulation works much better and is far cheaper. I have very two tall chimneys with 12 inch terra cotta liners.

Great product, big difference in drafts and better than that balloon product (competitor) - more efficient and less issues. Easy to install, notice a difference right after installation and it's an install and forget product. No need to check in unless you use your fireplace. If you do, be sure to remove it and install it back again which is easy.
