The present invention refers to a multilayered insulating panel or element h aving (a) two outer facings (1), and (b) a soft synthetic foam core material (2) h aving hollow profiles (3), connected to both outer facings (1). Also disclosed is a mult ilayered insulating panel or element having (a) two outer facings (1), and (b) soft c ore material phases in a spaced relationship between the two outer facings in such a mann er 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 high er 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 e lement possess acoustic insulating properties and mechanical strength.
