<p>The present invention refers to a multilayered insulating panel or element having (a) two outer facings (1), and (b) a soft synthetic foam core material (2) having hollow profiles (3), connected to both outer facings (1). Also disclosed is a multilayered insulating panel or element having (a) two outer facings (1), and (b) soft core material phases in a spaced relationship between the two outer facings in such a manner that both extremities of the soft core material are contacting the outer facings and having in between such soft core material phases, a second core material having a higher density than the soft core material, wherein only one extremity of each second core material phase contacts only one and the same outer facing. Both types of panel or element possess acoustic insulating properties and mechanical strength.</p> |
