A thermally insulating wall based upon a vacuum insulation technique includes two outer layers and a cavity bridged by a duct to accommodate cables or similar devices. The duct is produced by ducting bodies with flange-like inserts and is created by a material deformation on at least one of the outer layers. The material deformation at least substantially reaches the other outer layer and is linked in a vacuum tight manner with the other layer. Alternatively, both outer layers can have the material deformation.
