ABSTRACT:
The structural element contains a first sound-absorbing and thermally insulating layer (21) and a second sound-insulating, dimensionally stable supporting layer (23). Preferably, the first layer consists of a thermoformed fibre mat or a foam which is at least partially open-cell, and the second layer consists of a rigid, thermoformed synthetic material, for example a plastic material reinforced with glass fibres. A porous or microporous decorative layer (22) can be applied to the outside of the first layer and a thermoformed carpet (24) can be applied to the outside of the supporting layer. A heat-sealable adhesive layer (27) can be placed between the two layers, the said adhesive layer incrasing the bond between the two layers.
Because of the dimensionally stable supporting layer, the structural element can be used as a sound screen without a holding frame or as a sound-insulating bodywork part without a supporting surface, which makes it possible to reduce the weight of the overall construction and to make assembly simpler and cheaper.
