ABSTRACT:
A lightweight cover provides heat insulation for a heated vessel such as a soaking pit. The cover can be readily assembled in a manner providing for ease of repair plus simplicity of maintenance. The cover has a pair of opposing frame members with ceramic fiber insulation positioned therebetween. The insulation is secured in movable engagement such as a free-floating and swinging engagement. In this mode, compression can be exerted against the insulation to most desirably reduce heat loss otherwise caused by heat induced ceramic fiber shrinkage. Moreover, with this structure a ceramic fiber heat seal can be achieved around edges of the soaking pit.
