A composite article (10) includes a first layer (12), a second layer (14), and a third layer (16). The first layer (12) includes a polymeric material and has a show surface (18) and a reinforcing surface (20) opposite from the show surface (18). The second layer (14) abuts the reinforcing surface (20) of the first layer (12) and comprises a spray applied rigid polyurethane foam substantially free of reinforcing fillers. The third layer (16) abuts the second layer (14) opposite the first layer (12) and comprises a spray applied rigid polyurethane elastomer substantially free of reinforcing fillers.
