Abstract

An oven muffle has mutually spaced apart inner and outer insulating walls. An insulation layer composed of particulate material is disposed in an interstice between the inner and the outer insulating walls. At least one of the insulating walls is pretensioned toward the respective other insulating wall in order to exert a permanent pressure on the insulation layer.
