Output (English): The invented chamber or tunnel dryer and a preheater for ceramic moldings consists of thermally insulated sheet metal elements (3) mounted on a base plate (1). The ceilings (6) and/or walls (2, 4) are formed as a self-supporting structure by self-supporting trough-shaped elements (3). These elements are formed by a fundamental surface (14) the edges of which are bent inwards forming so side walls (15), wherein the side walls (15) have inwards bent edge strips (16) extending substantially parallel with the fundamental surface (14) and the contacting marginal zones of which are fixedly coupled with each other, wherein several sheet metal elements (3) standing by their fundamental surfaces (14) in one common plane is held together by means of connections, using for example screws (23) interconnecting their side walls (15) via a sealing (22), while the sheet metal elements (3) following up in right angle the common plane are held by means of connections interconnecting the side walls (15) via the sealing (22) with the edge strips (16) and the fundamental surfaces (14) of the sheet metal elements (3) are covered with an insulating layer, for example an insulating filler (5) and/or mineral wool (7).
