Abstract

A heat-insulating housing, such as for an oven chamber of a household oven or a refrigeration chamber of a household refrigerating appliance, includes at least one working space which is surrounded by housing walls and can be closed by a door. The housing walls are formed from two substantially dimensionally rigid housing shells which are at a spacing from each other and together substantially enclose an intermediate space that can be evacuated and is filled with heat-insulating material which can be introduced loosely.
