Abstract
A laminate product comprising a foam core having a pair of opposed major surfaces and a cover layer secured with respect to each major surface is described. The cover layer contains a fibrous reinforcement layer that is substantially encapsulated by a polymer. It has been found that the use of a fibrous polymer layer (e.g., in place of conventional polyethylene film) results in a laminate product having significantly lower resistance to air flow resistance and significantly improved sound absorption properties.
