Review: Amazing! - I unfortunately bought the wrong size twice because I didn't measure. Finally got it correct on the 3rd try. I love it so much because it really makes such a huge difference. I had new double paned windows installed throughout the house, but because of the draft from my fireplace, it didn't help conserve heat. I had a hard time staying in my living room during the winters because it was so cold. This flue blocker has helped to stabilize the heat in my house and I could tell the difference immediately upon installation. My heater doesn't kick on as much anymore because of this product. I am so thankful for your company for helping conserve on my energy bill.
Review: Blocks the smell and the draft - Closes the 13 x 13 chimney flue and prevents up and down drafts as well as the smoky smell. Needs to be sold with a much longer attachment, as it is kind of ridiculous to believe the short attachment that comes with it is long enough to reach up through the throat of the chimney.

## Features

## Questions & Answers

**Q: How do I determine the correct size for my fireplace flue?**
A: Measure your flue's interior and choose a Flueblocker the same size or slightly larger. The wool pad pressure-fits and can be trimmed with scissors. Use the sizing guide to match your flue shape—round, square, or rectangular.

**Q: How difficult is installation? Do I need any special tools or supports?**
A: Choose an install spot you can reach by hand. Measure with a tape or ruler. A narrow area above the firebox is ideal. For higher spots, use 6” handle extenders to place the wool pad securely.

**Q: Will the product completely block cold drafts, odors, and heat loss?**
A: When fitted correctly, the FlueBlocker stops heating/cooling loss, drafts and odors from a dormant chimney. To eliminate odor, make sure you vacuum out all the ash from the firebox and seal any ash chute or outside intake attached to the firebox.

**Q: Which is right for my situation – a FlueBlocker or a Chimney Balloon?**
A: The Flueblocker is a durable, reusable chimney plug that handles moisture and is ideal for long-term use. The Chimney Balloon offers a tight seal and a breakaway feature for safety if a fire is lit accidentally.

**Q: How durable is the material? Is it worth the price?**
A: Chimney is harsh, moist, acidic environments. The Flueblocker uses coarse ionized Herdwick wool and durable resin hardware to seal air, wick moisture and resist odors. Chimney Balloons use a heat-reactive laminate to withstand chimney air conditions.

### ⭐⭐⭐ Works with issues for some chimneys
*by F***O on February 9, 2024*

So this seems to work OK but I had the following issues to get it to work and you should be aware. My chimney has a smoke chamber of a few feet, so I needed to buy MANY of the 6" extensions to get up to the flue. It seemed odd to me that there are not 1' and 2' extensions. The other, much bigger issue is that my damper opening was angled such that I could not get the flue blocker in. The plastic reinforcement stiffener combined with the handle made it impossible for me to find an angle where I could get through the damper. So I ended up using a dremel to cut the reinforcement on both sides so it could bend through the damper. Finally, because I had to use so many extensions to get to the flue, and perhaps because the stiffener needed to be cut, I needed to put a support in the fireplace so the extended handle didn't slide down. Basically, it held, but not really well with all the extensions on it. In terms of blocking the draft: yes, it seems to be doing that. But it was a LOT more fussing that suggested to get it to work. So just be aware of this if your fireplace has a long smokestack and a smallish damper opening. Cheers.
