Corrugated foam/film laminates

摘要

A laminate for use as a thermal insulating material includes a layer of a metal laminated to an expanded foam web. The foam web is formed with a plurality of ribs projecting from one surface of the web in the length direction thereof. The metal layer is laminated to the free edges of the ribs so as to define a plurality of closed channels extending in the length direction of the laminate. The metal layer may include a layer of a polymer to facilitate adherence of the metal layer to the foam web.
