Corrugated foam/film laminates for use as floor underlayment

摘要

A laminate for use as a floor underlayment material includes a film disposed on at least one surface of an expanded foam web. The foam web includes a plurality of ribs projecting from one surface of the web in a length direction thereof so as to define a corrugated surface. The film is disposed on the surface of the foam web opposite the corrugated surface. The film is preferably formed from a high density polymer so as to enhance the moisture barrier properties of the laminate. When installed between a subfloor and finish flooring, the laminate defines channels which enable moisture emanating from the subfloor to be directed out from the flooring system.
