8. A composite comprising:
at least partially cross-linked low density polyethylene foamed sheet comprising cork particles in an amount of between 1 PHR to 50 PHR; and
a moisture barrier layer of 10 microns to about 500 microns in thickness adhered to at least one side of the at least partially cross-linked low density polyethylene foamed sheet,
wherein the moisture vapor barrier layer is a single film layer comprising a cellulose-polyolefin vinyl acetate film,
wherein the cork particles are of an average particle size of 500 microns to 1000 microns and the foamed polymeric sheet comprises an average foam cell diameter between 600 microns to 1500 microns.
