The second layer is a metal layer that at least partially encapsulates the foam core; wherein the metal layer is selected to be aluminum or an aluminum alloy. The third layer is a layer of an insulating material located on at least one surface of the metal layer. The deposition of the insulating layer is accomplished via the use of a coaxial laser process.
