Abstract

A panel element for insulating acoustically undesirable vibrations is disclosed. The panel element comprises a closed-cell foam element for closing off a hollow body provided with an opening on at least one side. The foam element possesses a mounting structure by which it can be fastened to the hollow body. The foam element is configured to the shape of the opening, and has on its perimeter a mounting structure. The mounting structure consists of a self-contained peripheral groove open in the direction of the boundary. The groove and the boundary can be brought into engagement with one another in a sealing and positive manner.
