A heat-insulating sealing device is mountable between a bottom face of an openable top cover and a top face of a furnace bottom of a heating furnace which defines a furnace chamber. The heat-insulating sealing device includes outer and inner looped sealing strips adapted to surround the furnace chamber and adapted to provide a seal between the top cover and the furnace bottom. The outer looped sealing strip extends around the inner looped sealing strip, is made of a heat-resistant resilient polymeric material, and is adapted to be disposed distal from the furnace chamber. The inner looped sealing strip abuts against an inner side of the outer looped sealing strip, is adapted to extend around the furnace chamber, and includes a heat-resistant fabric.
