Abstract
In a heat resistant cabinet, a gypsum filling is provided in the interspace between the outer casing and the inner surface. In the upper part of the cabinet, at least one hollow space is present in the gypsum filling. This hollow space extends practically over the whole width and the whole depth of the cabinet. The ceiling is therefore provided by two relatively thin plates of gypsum spaced from each other and each containing a wire mesh for reinforcement, providing a good heat protection for the contents of the uppermost drawer, without adding any substantial vulnerability to impairment of heat protection by falling material or by falling of the cabinet.
