A heat-insulating panel is made by disposing a metal supporting member adjacent a felting screen to lay down a wet refractory fiber mat from an aqueous, refractory fiber-colloidal silica mixture about the metal member. The member has a central base section and a pair of wings extending in opposite directions from opposite edges of the central section, with the wings being disposed at an angle of between about 130 DEG and about 80 DEG to each other and each containing a plurality of holes. After drying, the member is embedded within the mat with individual fibers extending through the holes and firmly anchoring the member. The member is located adjacent the rear surface of the heat-insulating panel, and its central section contains an aperture through which a support rod is passed to mount the panel.
