A method for the preparation of composite products wherein a foam expands in contact with a laminated sheet, one of the layers of which is metallic, the pressure generated during expansion of a foam forces the laminated sheet to adopt a desired configuration and the foam adheres to the laminated sheet. Composite products having a mirror-like appearance may be prepared by the method.
