<p>The opening part (1) of the skylight consists of a single transparent piece comprising, around its main surface (4) substantially parallel to the roof, lateral edges (6, 7) and a lower edge (5), these edges pointing downwards in substantially vertical planes. The downward edges descend practically to the level of the horizontal part (3) of the skirt surrounding the vertical edges (2) of the same forming the frame of the skylight. The piece forming the opening part (1) may be curved between the lower downward-pointing edge (5) and the main surface (4) and between the lateral downward-pointing edges (6, 7) and the main surface (4). <IMAGE></p> |
