Abstract: A fire resistant and sound insulating wall structure, particularly for the ship building industry, includes vertical stiffeners and a surface plate attached to the vertical stiffeners, preferably by gluing. A relatively thin corrugated plate is attached to the surface plate by gluing. The corrugations of the corrugated plate are substantially horizontally oriented and accordingly the corrugated plate provides horizontal stiffness. The glue attachment of the surface plate to the vertical stiffeners is preferably secured by means of screws for maintaining the fire-resisting properties of the structure in the event of the glue being destroyed by the heat of a fire.
