ABSTRACT There is disclosed an extruded plastic foam panel having at least two dissimilar layers, each layer possessing a closed cell structure. One layer is relatively rigid, and there is at least one surface layer which is relatively com- pressible and flexible. The rigid layer is integral with the compressible layer(s). A method of pre- paration involves passing at least one feedstock foam panel through a pair of rolls separated by a distance that is less than the total panel thickness. Preferred products and processes are also disclosed. Certain problems of prior art products and processes are overcome.
