The invention relates to a structured component, in particular heat shield, consisting of at least two layers (1, 3) that can be interconnected, one of which is designed as a cover layer (1) and at least one of which is designed as a structured layer (3). Said structured layer or layers (3) has/have a perforation (7, 13) as the first structure, which is incorporated from the opposite side of the structured layer (3) to the cover layer (1). At least one additional structure (9, 11) is situated in the structured layer (3) containing the perforation (7, 13), said additional structure projecting on the opposite side to the cover layer (1). Since the perforation (7, 13), as the first structure of the structured layer (3), leads to the environment and the additional structure (9, 11) of the structured layer (3) is completely overlapped by the cover layer (1), a person having average skill in the art can obtain, in a surprising manner, extremely effective soundproofing and excellent thermal insulation in relation to known solutions that comprise corrugated sheet metal between two sheet metal cover layers. |
