- The 11” x 19” Chimney Flueblocker pressure fits into a 11" x 19" or smaller rectangular flue opening. (Actual product dimensions are 12" x 20") 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.
