A baking and roasting oven muffle (1) with a thermal insulation (2) surrounding its outside surface is inserted in an oven casing (3). In order to bring about further improvement of the thermal insulation for the baking and roasting oven muffle (1), the first insulation (2) is surrounded by a second, separate insulation (5), the said insulations being separated from one another by means of an air chamber (4) passing between them. <IMAGE>
