The Ultimate Seal has been proven to eliminate back smoking of a fireplace at negative pressure levels up to -25 PA, allowing you to maintain a traditional wood burning fireplace in states with the most stringent energy codes. The Ultimate Seal door features gasketed swing sections that surround each glass panel along with a gasket to seal the frame of the door to the face of the fireplace. The combination of these gaskets virtually eliminates heat loss from the home through the fireplace opening. With its extremely durable 1-1/4" x 1-1/4" angle iron doors, the The Ultimate Seal is the only option for true masonry heaters such as the Isokern, Tempcast or Timberline fireplaces.
The Ultimate Seal also offers optional handles, glass, screen features and finishes.
