<p>Synthetics panels are mounted to form a roof. Each panel has at least two apparent rows of tiles to form an elementary panel. One of the two rows, termed completer row, is to contact the corresponding row of the neighbouring panel, the other, incomplete, row is connected to the corresponding incomplete row of the neighbouring tile by an individual removable tile, which seals the contact between two complete rows of neighbouring panels. Pref. the elementary panels are connected by synthetic resin.</p> |
