Liberty Foundry Fireplace Draft Stopper

Transform your unused fireplace into an energy-efficient, visually appealing feature with the Liberty Foundry Hearth Stopper®. Designed as a decorative insulated fireplace cover, this innovative solution helps eliminate unwanted drafts while enhancing the overall comfort and style of your living space. The Hearth Stopper® is engineered with a durable insulated core that significantly reduces heat transfer through your fireplace opening. By sealing off one of the most common sources of air leakage in a home, it can help prevent up to 30% of heat loss, reducing strain on your HVAC system and lowering energy costs year-round.

The Hearth Stopper is a great option for a way to block off the fireplace that has a gas log set. Gas log sets require the fireplace damper to be propped open with a damper clip to prevent trapping gas in the fireplace throat. For this reason a gas log set will always cause energy leaks. With the Hearth Stopper, you can seal the front of the fireplace while allowing the damper to be propped open preventing any chance of trapping gas. 

Installation is simple and completely tool-free. The Hearth Stopper® can be set up or removed in minutes, making it convenient for seasonal use. Its lightweight yet sturdy construction allows homeowners to easily place or remove it whenever they want to enjoy a fire, with no permanent modifications required. 

To accommodate a wide range of fireplaces, the Hearth Stopper® is available in two standard sizes:
Standard: Fits openings up to 38" W x 26" H
Large: Fits openings up to 40" W x 32" H
