Abstract: A box body for a commercial vehicle, which has a surface element having a panel, includes a core layer, a dimensionally stable structural layer and an intermediate layer, one side thereof being adjacent to the core layer and an opposite side being adjacent to the structural layer. An integrally joined connection is produced between the structural layer and the side of the intermediate layer and between the core layer and the side of the intermediate layer. The intermediate layer has a thickness smaller than the thickness of the structural layer and consists of a material having a density that is higher than the density of the core layer. The side of the intermediate layer adjacent to the core layer has an affinity to the foamed plastic of the core layer and the side of the intermediate layer adjacent to the structural layer has an affinity to the structural layer.

Abstract: An insulating panel for a commercial vehicle superstructure, with an outer top layer and an inner top layer, including more than two plies, and with a core layer in a thermally insulating material between the top layers. At least one of the top layers is constructed as an at least three-ply sandwich, including an outer ply in light metal material associated with the respective outside of the insulating panel, an inner ply in light metal material associated with the core layer and a core ply having an integrally joined connection to the outer ply and the inner ply, including a core ply material having a higher strength than the light metal material of the outer and inner ply.
