An insulation chimney is described, with an inner pipe which guides the smoke gas, an insulating layer surrounding the inner pipe, and with a casing made of casing stones placed on top of one another, which surround the insulating layer in a supporting manner and preferably have in the corner regions back-ventilating ducts open towards the insulating layer, which are connected in the lower region of the chimney to an air inlet opening, as well as with a console between two casing stones above the air inlet opening , on which the insulating layer is supported. In this case, the console (9) consists of one or a number of steel sheet pieces (10, 13) which are inserted into the regions of a joint (8), in which there are no back-ventilating ducts (11), between two casing stones (1, 5) above or in the region of the air inlet opening (7). The sheet pieces extend inwardly as far as the inner pipe (2). <IMAGE>
