ABSTRACT:
The sound-absorbing insulation element is used everywhere sound and/or heat sources have to be shielded, preferably in automotive engineering as a heat shield. The insulation element comprises at least one studded sheet-shaped element which is provided with strengthening embossments. The strengthening embossments have an embossment base and embossment flanks. According to the invention, the sheet-shaped element exhibits material compression, that is to say material hardening, in the region of the embossment flanks. Fissures which have a bizarrely shaped contour lie in the embossment base. These fissures are produced by the stretching and tearing of the embossment base.
