Abstract:
A firebox cover for thermally sealing off a firebox while not in use, the cover comprising:a flexible insulating barrier member sized and shaped to cover a firebox opening within a room preventing thermal energy within the room from exiting through the firebox opening and preventing thermal energy within the firebox from entering the room, the barrier member having a cellular structure with a thermally reflective front face and thermally reflective back face; a sealing member about a periphery of the barrier member providing a substantially air tight seal about edges of the barrier member when the sealing member is magnetically affixed to a metallic surface surrounding the firebox opening during use of the cover, the sealing member having a pocket for receiving the periphery of the barrier member, an expansion portion for maintaining contact between the sealing member and the surface surrounding the firebox opening during pressure changes across the barrier member, and a cavity sized and shaped for receiving a magnetic member; and a magnet member sized and shaped to fit within the cavity of the sealing member having magnetic properties to magnetically affix the sealing member to the metallic surface surrounding the firebox opening.
