A furnace wall lining is formed of ceramic fiber modules or batts arranged in stacks or layers between more rigid layers of insulating material to which are connected hangers for supporting electrical resistance heating elements. The more rigid insulating layers are preferably a dense fiber board insulating material having openings into which may be hooked one end of an elongated hanger which lies in a groove across the top face of the rigid insulating layer. An end of the hanger projects inwardly into the furnace chamber from the inner face of the furnace lining and supports the heating element. The rigid layers may be used to compress a stack of soft wall batts therebetween.
