ABSTRACT OF THE DISCLOSURE A panel for self-supporting roof structures of extruded profile elements having at least one main duct closed at the ends with closing members which are made of plastics material and have the same profile as the profile elements and is closed at one end. The closing member is of so reduced dimensions as to fit into any main duct in the profile element while allowing some air exchange without the risk of penetration of dirt. The closing member has preferably resilient sealing flaps on two opposite sides so that one and the same member can be used for closing profile elements of varying size and shape, e.g. as a result of manufacturing inaccuracies. A V-shaped groove encircles the outer surface of the closing member and permits movement of the two parts of a bipartite flap.
