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. Review: Pays for itself! - Stumbled on this and tried it. Works very well to block the cold in my drafty fireplace. I highly recommend it. ## Features - STOP DRAFTS AND ODORS - This Round Chimney Flueblocker pressure fits into a 8" or 9" round flue opening. (Actual product dimensions are 10" round) It can be trimmed with scissors to accommodate sizing and hardware. - IMPORTANT - The Flueblocker CANNOT BE USED with an ACTIVE VENTED GAS LOG set. For safety, a VENTED GAS LOG would need to be DISABLED or REMOVED in order to use the Flueblocker. - MULTIPLE BENEFITS - The seal it creates stops DRAFTS, ODORS, NOISE, and DEBRIS from coming into your home through the fireplace. Using a Flueblocker can pay for itself in one heating season, making your home will feel warmer by keeping warm air in and cold drafts out. - EASY INSTALLATION & REMOVAL – No more fussing with an ineffective balloon, pillow or fabric fireplace covers – Simply insert the draft stopper into your fireplace flue just above the firebox. The Flueblocker is easily removed when you are ready to use your fireplace. - NATURALLY RENEWABLE & HIGH QUALITY – The Flueblocker is made out of naturally renewable, dense, durable, and rigid 100% Herdwick Wool imported from England. These attributes allow it to stay in place without puncturing or deflating. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00G48ESRS | | Batteries required | No | | Brand | Chimney Sheep | | Color | Off-white | | Customer Reviews | 4.3 4.3 out of 5 stars (1,191) | | Global Trade Identification Number | 00700115980159 | | Is Discontinued By Manufacturer | No | | Item Weight | 6.4 ounces | | Item model number | CA041 | | Manufacturer | Chimney Sheep | | Material | Wool | | Maximum Gap Fill | 9 Inches | | Number of Pieces | 1 | | Product Dimensions | 24.41 x 24.41 x 24.41 inches | | UPC | 700115980159 799493546323 | ## Product Details - **Brand:** Chimney Sheep - **Color:** Off-white - **Material:** Wool - **Maximum Gap Fill:** 9 Inches - **Number of Pieces:** 1 ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/610ayLkbBFL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Sometimes you just have to pay for quality *by K***R on January 16, 2023* Let's just deal with the elephant in the room first - this thing seems stupid expensive for what it is.
