Abstract
Abstract A fiber blanket module having a rectangular or box-shaped frame attached by suitable attachment structure to a wall of a furnace or other high temperature equipment to insulate such equipment. Each of two strips of woven metal oxide fiber cloth is suspended between one set of opposite sides of the frame, forming a pocket. The pocket is filled with suitable insulating material, which includes bulk, unconsolidated ceramic fiber, refractory fiber blankets, and the like.
