Metallised support has a rigid expanded foam organic material, e.g. a polymethacrylate imide or vinyl polymer, support (1) covered partially with a thermoplastic organic polymer, pref. a copolymer of propylene and methylpentene, film (3) covered with a metal, e.g. copper, aluminium or alloys, layer (5). An electronically conductive convection (6) passes through the foam or films to connect the separate metallised surfaces. Also claimed is the prodn. by: activating the surface of the thermoplastic material; placing the activated surface against the support foam; placing a metal layer on the other activated surface of the thermoplastic; joining the assembly under heat and pressure.
