Flueblocker

Flueblocker Chimney Draft Stopper

The Flueblocker is a durable chimney draft stopper designed to help seal unused fireplace flues and improve your home’s comfort and energy efficiency. Made from dense, rigid Herdwick wool, it creates a secure pressure fit above the firebox or directly in the damper opening to help reduce unwanted airflow, odors, and debris entering through your chimney.

Unlike inflatable chimney pillows or temporary covers, the Flueblocker is built for repeated use and performs well even in rough-surfaced chimneys. Its rigid wool construction naturally conforms to the shape of the flue while providing effective insulation and air sealing capabilities. The material can easily be trimmed with scissors for a customized fit and slotted to accommodate damper hardware when needed.

The Flueblocker helps keep warm air inside during colder months by minimizing heat loss through the chimney. It also helps block cold drafts, unpleasant chimney odors, outdoor noise, and unwanted debris that may otherwise make their way into your living space. When you’re ready to use your fireplace, simply remove the Flueblocker and store it until it’s needed again.

Available in multiple round, square, and rectangular sizes, the Flueblocker offers a practical solution for homeowners looking to improve fireplace efficiency without complicated installation. Its reusable design makes it a cost-effective investment that can provide benefits season after season.
