Maintain a pressure-fit seal that stops fireplace flue drafts, contaminants, smells and animals with this fireplace draft stopper. It helps keep out chimney odors and helps to muffle bird noise and other outside sounds. Inserting this chimney flue blocker improves efficiency by keeping cold air from getting in and reducing the energy needed to heat the home. Double-felted Herdwick wool construction is naturally dense and is durable, standing up to rugged chimney environments. This rectangle-shaped fireplace flue stopper measures 8' x 20' to pressure fit into a 7' x 19' or smaller rectangular flue opening. It offers multiple installation options, which are made quick and easy with an extended-length handle. Use the dense wool pad with or without a damper for an easy setup. The end of the handle is also a convenient place to hang a note, letting others know that the chimney is plugged and blocked. Disable or remove an active vented gas log set before using this draft stopper for safety reasons.
