A laminate composition of a thin film of low density polyethylene adhered to a sheet of low density polyethylene foam by means of a very thin layer of low density polyethylene. The polyethylene foam has a low density which is preferably between about 1.9 pcf and about 2.2 pcf. The bottom polyethylene film serves as a vapor barrier. One side of the polyethylene film extends beyond one edge of the polyethylene foam sheet. The laminate composition is installed in a free floating manner on the concrete subflooring, with the polyethylene film or the polyethylene foam sheet contacting the surface of the concrete subflooring. The laminate composition is usually in long strips, so when it is installed one edge of one strip overlies the extended portion of the polyethylene film of an adjacent strip. Tape having adhesive on both sides can be positioned between the overlay region to adhere together the overlaid portions to prevent movement thereof during installation of the laminate wood finish flooring. Then the laminate wood finish flooring, in plank form, is installed on top of the laminate composition in a free floating manner. The laminate wood planks fit together in a tongue-in-groove manner and are glued together.

[ What is claimed is:] [1.] A flooring consisting essentially of a concrete subflooring, a laminate adjacent to said concrete subflooring of a thin sheet of closed cell polyethylene foam having a thickness of 0.03 to 0.1 inches and a density of 1 to 5 pcf and a thin sheet of polyethylene film having a thickness of 1 to 5 mils adhered to said foam, and a laminate wood flooring adjacent to said foam-film laminate, the polyethylene film being in contact with the concrete subflooring and the polyethylene foam sheet being in contact with the laminate wood flooring, or the polyethylene film being in contact with the laminate wood flooring and the polyethylene foam sheet in contact with the concrete subflooring said polyethylene film sheet having a larger surface area than said polyethylene foam sheet, at least one edge of the polyethylene film sheet extending beyond the corresponding edge of the polyethylene foam sheet, wherein said at least one edge of polyethylene film sheet having a length such that it is capable of overlapping an adjacent foam-film sheet.
