ABSTRACT:
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.
