If your conventional masonry fireplace is giving you the cold shoulder, then Fireplace Doors Online has the answer to your chilling dilemma. Air-Seal Door System seals masonry fireplaces. These air sealed doors stop cold air drafts from invading your home and capture the warm air from your fireplace and prevent it from being lost up the chimney.
Like any fireplace door, it is important that gasketed doors be left open while burning a hot fire. Damage to the door, door frame, and/or the tempered glass is likely to result and will not be covered under warranty. They are not designed to be used or sold as an "air tight" option to a woodstove, or fireplace insert. Their value is in reducing heated air loss through the fireplace when the fire is dying or extinguished, and minimizing cold air infiltration from a down drafting chimney
