Odors, and Noise: When your fireplace sits idle between fires, your chimney acts as an open channel for cold air, stale odors, outside noise, and debris to pour into your home. The Flueblocker chimney balloon draft stopper pressure-fits into 10 inch round flue openings, creating a snug seal that blocks drafts, odors, noise, and falling debris; actual product diameter is 12 inches for a secure, compression-based fit\u003c\/li\u003e\u003cli\u003eYear-Round Protection That Lasts: Install the Flueblocker in spring and leave it through winter; it is safe for year-round use in inactive fireplaces and wood stoves. In winter, it keeps warm air in and cold drafts out; in summer, it blocks humidity and heat from entering through the flue. With seasonal use, the wool plug lasts 7-plus years; with continuous year-round installation, it can last indefinitely, saving you repeated replacement costs\u003c\/li\u003e\u003cli\u003eWorks With Any Damper Condition: A broken, stuck, or missing damper is no obstacle. The Flueblocker sits above the firebox directly in the flue opening, independent of the damper mechanism, so damper condition is completely irrelevant. Installation requires no tools; simply press it into the hole for a snug pressure fit. Need a tighter fit? Trim the edges with scissors to accommodate 10 inch round chimney flue openings with precision\u003c\/li\u003e\u003cli\u003eDense Wool That Holds Its Shape: Made in England from 100% Herdwick Wool, a uniquely dense, rigid natural fiber from heritage sheep of the English Lake District.

Naturally moisture-wicking, it delivers 7-plus years of reliable performance with seasonal use.

Even with the damper closed, gaps in the flue allow cold air, odors, noise, and debris to enter your home. The result is familiar to most homeowners: drafty rooms, higher heating bills, and a smell no candle covers. The Flueblocker is a reusable wool plug that pressure-fits into 8-9 inch round flue openings just above the firebox. No tools, no hardware. Press it in to install; pull it out when ready for a fire. The actual diameter is 10 inches, engineered to compress into the flue and hold firm through a snug, pressure-based fit. Every Flueblocker is made in England from 100% Herdwick Wool, a dense, rigid natural fiber from heritage sheep of the English Lake District. Naturally moisture-wicking, it holds its shape season after season. Material performance is validated under the BBA Agrement Certificate. As a reusable wool alternative to inflatable chimney balloons, the Flueblocker relies on dense compression rather than air pressure. Maintenance-free and always ready to use. Trimmable with scissors, it works whether your damper is functioning, broken, or missing entirely. Safe to leave installed year-round: in winter it keeps warm air in and blocks cold drafts; in summer it prevents humidity and heat from entering. With seasonal use the wool lasts 7-plus years; with continuous installation, indefinitely. Safety note: Do not use with an active vented gas log set. Turn off or disable any gas source before installation. Always remove before lighting any fire. The Flueblocker meets IECC 2009 Section 402.4.2 air sealing standards and may qualify for federal tax credits under the Inflation Reduction Act (HR 5376). Backed by a 1-year limited warranty. Ideal for homeowners with unused or seasonal fireplaces, property managers, and energy-conscious households. Block drafts, save on heating, and cover noise; it can pay for itself in one heating season. \u003c\/p\u003e\u003c\/div\u003e\u003ch5\u003eProduct description\u003c\/h5\u003e\u003cdiv style=\\\"display:flex;flex-wrap:wrap;gap:0;margin:0;padding:0;line-height:0;font-size:0;\\\"\u003e\u003cimg src=\\\"https:\/\/m.media-amazon.com\/images\/S\/aplus-media-library-service-media\/e52bac4b-c7db-4d16-9464-6a55b90790f9.__CR0,0,1464,600_PT0_SX1464_V1___.jpg\\\" style=\\\"flex:1 1 auto;min-width:120px;max-width:100%;height:auto;object-fit:contain;margin:0!important;padding:0!important;display:block;border:0;vertical-align:top;line-height:0;\\\" loading=\\\"lazy\\\" \/\u003e\u003cimg src=\\\"https:\/\/m.media-amazon.com\/images\/S\/aplus-media-library-service-media\/ebb6ab5e-3dc9-4c90-847e-7d131c686516.__CR0,0,1464,600_PT0_SX1464_V1___.jpg\\\" style=\\\"flex:1 1 auto;min-width:120px;max-width:100%;height:auto;object-fit:contain;margin:0!important;padding:0!important;display:block;border:0;vertical-align:top;line-height:0;\\\" loading=\\\"lazy\\\" \/\u003e\u003cimg src=\\\"https:\/\/m.media-amazon.com\/images\/S\/aplus-media-library-service-media\/2b5270f4-9c8d-40fe-95c8-d67684f79b0c.__CR0,0,1464,600_PT0_SX1464_V1___.jpg\\\" style=\\\"flex:1 1 auto;min-width:120px;max-width:100%;height:auto;object-fit:contain;margin:0!important;padding:0!important;display:block;border:0;vertical-align:top;line-height:0;\\\" loading=\\\"lazy\\\" \/\u003e\u003cimg src=\\\"https:\/\/m.media-amazon.com\/images\/S\/aplus-media-library-service-media\/6d71215e-bae0-490d-98d4-6aff5f0780a9.__CR0,0,1464,600_PT0_SX1464_V1___.jpg\\\" style=\\\"flex:1 1 auto;min-width:120px;max-width:100%;height:auto;object-fit:contain;margin:0!important;padding:0!important;display:block;border:0;vertical-align:top;line-height:0;\\\" loading=\\\"lazy\\\" \/\u003e\u003cimg src=\\\"https:\/\/m.media-amazon.com\/images\/S\/aplus-media-library-service-media\/c267d77d-fa32-4ff8-92f4-2c4bb4e075f7.__CR0,0,1464,600_PT0_SX1464_V1___.jpg\\\" style=\\\"flex:1 1 auto;min-width:120px;max-width:100%;height:auto;object-fit:contain;margin:0!important;padding:0!important;display:block;border:0;vertical-align:top;line-height:0;\\\" loading=\\\"lazy\\\" \/\u003e\u003c\/div\u003e\u003ch5\u003eHow do I determine the correct size for my fireplace flue?\u003c\/h5\u003e\u003cp\u003eHow do I determine the correct size for my fireplace flue?\u003c\/p\u003e\u003cp\u003eMeasure your flue\u0026#039;s interior and choose a Flueblocker the same size or slightly larger.

Even with the damper closed, gaps in the flue allow cold air, odors, noise, and debris to enter your home. The result is familiar to most homeowners: drafty rooms, higher heating bills, and a smell no candle covers. The Flueblocker is a reusable wool plug that pressure-fits into 8-9 inch round flue openings just above the firebox. No tools, no hardware. Press it in to install; pull it out when ready for a fire. The actual diameter is 10 inches, engineered to compress into the flue and hold firm through a snug, pressure-based fit. Every Flueblocker is made in England from 100% Herdwick Wool, a dense, rigid natural fiber from heritage sheep of the English Lake District. Naturally moisture-wicking, it holds its shape season after season. Material performance is validated under the BBA Agrement Certificate. As a reusable wool alternative to inflatable chimney balloons, the Flueblocker relies on dense compression rather than air pressure. Maintenance-free and always ready to use. Trimmable with scissors, it works whether your damper is functioning, broken, or missing entirely. Safe to leave installed year-round: in winter it keeps warm air in and blocks cold drafts; in summer it prevents humidity and heat from entering. With seasonal use the wool lasts 7-plus years; with continuous installation, indefinitely. Safety note: Do not use with an active vented gas log set. Turn off or disable any gas source before installation. Always remove before lighting any fire. The Flueblocker meets IECC 2009 Section 402.4.2 air sealing standards and may qualify for federal tax credits under the Inflation Reduction Act (HR 5376). Backed by a 1-year limited warranty. Ideal for homeowners with unused or seasonal fireplaces, property managers, and energy-conscious households. Block drafts, save on heating, and cover noise; it can pay for itself in one heating season. \u003c\/p\u003e\u003c\/div\u003e\u003ch5\u003eProduct description\u003c\/h5\u003e\u003cdiv style=\\\"display:flex;flex-wrap:wrap;gap:0;margin:0;padding:0;line-height:0;font-size:0;\\\"\u003e\u003cimg src=\\\"https:\/\/m.media-amazon.com\/images\/S\/aplus-media-library-service-media\/e52bac4b-c7db-4d16-9464-6a55b90790f9.__CR0,0,1464,600_PT0_SX1464_V1___.jpg\\\" style=\\\"flex:1 1 auto;min-width:120px;max-width:100%;height:auto;object-fit:contain;margin:0!important;padding:0!important;display:block;border:0;vertical-align:top;line-height:0;\\\" loading=\\\"lazy\\\" \/\u003e\u003cimg src=\\\"https:\/\/m.media-amazon.com\/images\/S\/aplus-media-library-service-media\/ebb6ab5e-3dc9-4c90-847e-7d131c686516.__CR0,0,1464,600_PT0_SX1464_V1___.jpg\\\" style=\\\"flex:1 1 auto;min-width:120px;max-width:100%;height:auto;object-fit:contain;margin:0!important;padding:0!important;display:block;border:0;vertical-align:top;line-height:0;\\\" loading=\\\"lazy\\\" \/\u003e\u003cimg src=\\\"https:\/\/m.media-amazon.com\/images\/S\/aplus-media-library-service-media\/2b5270f4-9c8d-40fe-95c8-d67684f79b0c.__CR0,0,1464,600_PT0_SX1464_V1___.jpg\\\" style=\\\"flex:1 1 auto;min-width:120px;max-width:100%;height:auto;object-fit:contain;margin:0!important;padding:0!important;display:block;border:0;vertical-align:top;line-height:0;\\\" loading=\\\"lazy\\\" \/\u003e\u003cimg src=\\\"https:\/\/m.media-amazon.com\/images\/S\/aplus-media-library-service-media\/6d71215e-bae0-490d-98d4-6aff5f0780a9.__CR0,0,1464,600_PT0_SX1464_V1___.jpg\\\" style=\\\"flex:1 1 auto;min-width:120px;max-width:100%;height:auto;object-fit:contain;margin:0!important;padding:0!important;display:block;border:0;vertical-align:top;line-height:0;\\\" loading=\\\"lazy\\\" \/\u003e\u003cimg src=\\\"https:\/\/m.media-amazon.com\/images\/S\/aplus-media-library-service-media\/c267d77d-fa32-4ff8-92f4-2c4bb4e075f7.__CR0,0,1464,600_PT0_SX1464_V1___.jpg\\\" style=\\\"flex:1 1 auto;min-width:120px;max-width:100%;height:auto;object-fit:contain;margin:0!important;padding:0!important;display:block;border:0;vertical-align:top;line-height:0;\\\" loading=\\\"lazy\\\" \/\u003e\u003c\/div\u003e\u003ch5\u003eHow do I determine the correct size for my fireplace flue?\u003c\/h5\u003e\u003cp\u003eHow do I determine the correct size for my fireplace flue?\u003c\/p\u003e\u003cp\u003eMeasure your flue\u0026#039;s interior and choose a Flueblocker the same size or slightly larger.

Even with the damper closed, gaps in the flue allow cold air, odors, noise, and debris to enter your home. The result is familiar to most homeowners: drafty rooms, higher heating bills, and a smell no candle covers. The Flueblocker is a reusable wool plug that pressure-fits into 8-9 inch round flue openings just above the firebox. No tools, no hardware. Press it in to install; pull it out when ready for a fire. The actual diameter is 10 inches, engineered to compress into the flue and hold firm through a snug, pressure-based fit. Every Flueblocker is made in England from 100% Herdwick Wool, a dense, rigid natural fiber from heritage sheep of the English Lake District. Naturally moisture-wicking, it holds its shape season after season. Material performance is validated under the BBA Agrement Certificate. As a reusable wool alternative to inflatable chimney balloons, the Flueblocker relies on dense compression rather than air pressure. Maintenance-free and always ready to use. Trimmable with scissors, it works whether your damper is functioning, broken, or missing entirely. Safe to leave installed year-round: in winter it keeps warm air in and blocks cold drafts; in summer it prevents humidity and heat from entering. With seasonal use the wool lasts 7-plus years; with continuous installation, indefinitely. Safety note: Do not use with an active vented gas log set. Turn off or disable any gas source before installation. Always remove before lighting any fire. The Flueblocker meets IECC 2009 Section 402.4.2 air sealing standards and may qualify for federal tax credits under the Inflation Reduction Act (HR 5376). Backed by a 1-year limited warranty.
