A multilayered insulating panel having improved acoustic insulating properties and mechanical strength has two outer facings and a soft synthetic foam core having cavities. The foam core with the cavities is in intimate contact with the facings. The cavities are arranged so that the gaps between the core material and the outer facings are in alternate patterns with respect to the opposing outer facings.

[ I claim:] [1.] A multilayered insulating panel or element having both acoustic insulating properties and mechanical strength comprising:(a) two outer facings (1), and(b) a soft synthetic core material (2) wherein the soft synthetic core material (2) is a single, continuous soft synthetic foam core material (2) having cavities (3), the core material (2) contacting both outer facings (1) in an alternate pattern, such that the core material (2) contacts only one of the two outer facings (1) at any point in a cross-section of the panel, thereby providing a gap (4) between the core material (2) and the opposing outer facing (1).
