Covering component for protecting outer surfaces of buildings from atmospheric agents, incorporating heat exchanger means, and system for the external covering of buildings using such a component
A covering component for protecting outer surfaces of buildings from atmospheric agents comprises a metal sheet (7), an insulating mass (8) arranged below said sheet (7), and heat exchanging means (7–9, 11, 12) comprising at least a passage channel (7B), the latter being an integral part of the component and being designed to be part of a solar energy heating system for a heat conveying fluid. The passage channel consists of a rib (7B) of the sheet (7) defining a cross section opening towards the insulating mass (8), and the outer surface of the passage channel thus formed is almost completely exposed to sunlight. In the preferred embodiment of the invention there is provided a cover made of transparent material (11), arranged above the sheet (7), which delimits together with the latter at least part of a hollow space (12) into which the rib (12) projects.
