Abstract: A sheet-like composite element for construction purposes. The longitudinal edges of the composite element is formed by U-shaped profiled edge members having legs that are directed toward one another and serve as supports for an inner and an outer cover layer, between which is disposed a core layer of hard foam. The edge members function as support elements, and have a cross-sectional area that conforms to the respective stress of the composite element. The hard foam core layer, which fills not only the space between the cover layers but also the hollow space of the profiled edge members, stabilizes the latter. Such a composite element permits free selection of the material and dimensions of the cover layers with a view toward the respective application of the composite element.
