## Features

- Dense Herdwick Wool Construction: The Flueblocker is a durable wool alternative to inflatable Chimney Balloons. Built from 100% Herdwick wool sourced from heritage sheep farms in Cumbria, England, this chimney blocker weighs 2.6 lbs and holds its rigid shape season after season. Reusable for 10+ years of seasonal install-and-remove cycles and backed by a 1-year limited warranty. Wool is a naturally renewable fiber
- Sizing and Custom Fit: This model fits rectangular flue openings up to 13" x 35" (actual wool dimensions 14" x 36" for a pressure fit). Measure the width and depth of your flue opening just above the firebox, then choose a Flueblocker at least 1 inch larger than each dimension. Trim edges with scissors for a snug custom fit. Designed for rectangular flues only; check your flue shape before ordering. Multiple sizes available for other chimney flue openings
- Drafts, Odors, and Heat Loss Blocked: An open chimney flue lets cold air, odors, noise, and debris into your home while warm air escapes up the vent. The Flueblocker chimney draft stopper pressure-fits snugly to help block drafts, reduce fireplace odors, and retain heat during fall, winter, and spring. IECC 2009 compliant (section 402.4.2) as a prescriptive insulation product; may pay for itself in one heating season by reducing heat loss
- No Tools, Installs in Seconds: Press the Flueblocker into the flue just above the firebox; the pressure fit holds it firmly with no hardware or adhesives. Works with or without an existing damper, whether broken, missing, or functioning. Removal is simple; pull it out before you burn. Important: You must remove the Flueblocker before lighting fireplace.
- Compatibility and Tax Credit Info: The Flueblocker cannot be used with active vented gas log sets; gas logs must be fully disabled or removed first. For wood-burning and unused fireplaces, it is recommended by chimney professionals and energy auditors. As an air sealing and insulation product, it may qualify for federal tax credits under the Inflation Reduction Act (HR 5376). Made in England. Ideal for homeowners or renters with seasonal or unused indoor fireplaces

## 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.
