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.. Review: Great odor blocking - 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. ## Features - The 13” x 35” Chimney Flueblocker pressure fits into a 13" x 35" or smaller rectangular flue opening. (Actual product dimensions are 14" x 36") Always buy a Flueblocker a couple of inches larger than your opening on both dimensions to ensure proper fit. 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 and 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 and HIGH QUALITY – The Flueblocker is made out of naturally renewable, dense, durable, and rigid 100% Herdwick Wool imported from England. These at-tributes allow it to stay in place without puncturing or deflating. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08K1J95ZT | | Batteries required | No | | Customer Reviews | 4.3 4.3 out of 5 stars (413) | | Is Discontinued By Manufacturer | No | | Item Weight | 2.75 pounds | | Item model number | FB13x35REC | | Manufacturer | Chimney Sheep | | Product Dimensions | 36 x 14 x 1 inches | | Warranty Description | 1 year limited warranty. | ## Images ![Flueblocker for 13"x35" Chimney - Draft Stopper Wool Fireplace Plug - Image 1](https://m.media-amazon.com/images/I/71fH2idLbdL.jpg) ## Available Options This product comes in different **Size** options. ## 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 ### ⭐⭐⭐⭐⭐ keeps the heat in! *by B***N on January 6, 2021* Standing next to my fireplace I could feel a draft.

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. ### ⭐⭐⭐⭐ Effective though expensive *by L***. on September 20, 2024* 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. ## Frequently Bought Together - Flueblocker for 13"X35" Chimney Flue – Chimney Sheep Fireplace Draft Stopper Plug Replacement Damper Fireplace Tool – Better Than Inflatable Pillow or Balloon–Save Energy Block Odor & Debris - Flueblocker for 16"X16" Square Chimney Flue - Chimney Sheep Fireplace Draft Stopper Replacement Damper Fireplace Plug - Better Than Inflatable Pillow or Balloon - Save Energy Block Odor & Debris --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/240089228-flueblocker-for-13x35-chimney-draft-stopper-wool-fireplace-plug](https://www.desertcart.sk/products/240089228-flueblocker-for-13x35-chimney-draft-stopper-wool-fireplace-plug) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-05*
