Abstract
Abstract A simulated wood panel comprising a substrate with rigid elongated reinforcing members and foamed polymer coating which is molded to simulate the appearance of wood grain. The method for making the simulated wood panel comprises the steps of providing a substrate, providing elongated reinforcing means for said substrate, and covering said substrate and said reinforcing means with a foamed polymer.
