Abstract

The invention relates to a turbine casing (1) comprising at least one insulation mat (2) for thermally insulating the external face (3) of the turbine casing from the surroundings. In order to prevent eddies from forming between the insulation mat (2) and the external face of the turbine casing, a gas-impermeable cover (4) is arranged in at least some areas on the external face of the insulation mat.
