About
Dense Wool Beats Inflatables: The Flueblocker is made from 100% Herdwick wool imported from England, a dense, rigid natural material that maintains a firm pressure fit season after season. Unlike inflatable balloons or pillows, it won't puncture, deflate, or lose its seal over time. No re-inflating, no surprises. Rated for 10+ years of reuse, this chimney plug is built to deliver reliable performance season after season
Measure Your Flue for a Perfect Fit: This 8"x20" wool pad pressure-fits into 7"x19" or smaller rectangle chimney flue. The extra inch on each side is what creates the firm seal. To confirm fit, measure the inside dimensions of your flue tile opening just above the firebox before ordering. If your opening is slightly smaller, the Flueblocker trims easily with scissors to fit around hardware or irregular edges. Check your chimney flue dimensions before purchasing
Stops Drafts, Odors, Noise, and Soot: The dense wool pad creates a reliable seal that significantly reduces cold drafts pouring down an unused chimney and dampens outside noise coming through the flue. In summer, it blocks the stale, musty chimney odors that humidity pushes into living rooms. The seal also helps keep soot and ash from entering your home through the chimney. Ideal for winter heating season, humid summer months, or any time your fireplace sits unused
Tool-Free Install in Seconds: Simply push the Flueblocker into the flue just above the firebox. It works with or without an existing damper, whether yours is damaged, missing, or just leaky. When you're ready to use the fireplace, pull it out in seconds and reinstall it just as fast when the fire is out. Handle extenders are available for high out of reach installs. Perfect for homeowners, property managers, or hearth professionals who want a no-fuss chimney block off cap that actually stays put
Safety First, Savings All Season: The Flueblocker cannot be used with active vented gas log sets; remove or disable gas logs before installing, and always remove it before lighting fireplace. By keeping warm indoor air inside and cold drafts out, it can pay for itself in one heating season. Made from naturally renewable Herdwick wool, shorn annually and regrown, it's a durable, responsible choice for long-term chimney sealing
