The utility model relates to a building material field is decoration function singleness, interior plate easy dewfall in winter, the poor shortcoming of metal sheet sound absorption effect that shows in the present actual case of engineering row to the metal clip core, through constructing and the optimization of material a novel composite metal battenboard of designing. Its characterized in that panel structure includes stands by as an outsider and outer coloured coating metal sheet layer, waterproof layer, heat preservation, vapour barrier layer, the inlayer wallboard layer of the setting of interior order. The reinforcing waterproof layer of addding between outer coloured coating metal sheet layer and heat preservation is for PVC waterproofing membrane or synthetic high polymer coiled material or SBS modified asphalt coiled material or the flexible waterproofing membrane of second third gradegrade C of EPDM ternary. The vapour barrier layer of setting up between heat preservation and inlayer wallboard is waterproof polymer wainscot of all kinds of paper bases or thermal -insulated reflection aluminum foil material. The utility model discloses a five layers of composite construction, promoted greatly the battenboard heat preservation, waterproof, decorate the function, strengthen human use comfort.
