<p>The panel for supporting a roof covering (24) laid over a layer (23) of an insulating material, has trapezoid-section corrugations forming supporting ribs (41). The edges of the panels (21, 22) end in flat strips (40, 42) of reduced width, enabling the overlapping edges to be adjusted relative to one another before fixing, eg. with self-tapping screws (25, 27). The panels can be made, for example, from sheet metal, plastics, glass fibre-reinforced resin, or cement and fibre.</p> |
