A component (1) such as a rocket exhaust duct subject to high thermal loads in operation has a part (5) with a compound wall structure. The part has inner (8) and outer (9) walls with one or more cooling channels (11) defined between the walls. An end portion of the inner wall is joined to a second part of the complete component with the joint between the two parts located at a distance from the hollow interior of the component.
