The plate (1) has, along the one side edge (4), a suitable first flange (25) in extension of the rear side (3) in which fixture components, e.g. screws (28), can be applied. In the opposite side edge (6), a second flange (19) projecting from the front side (2) of the plate has its free end inwardly bent and terminated by the tongue (7). The two flanges (19,25) in two adjacent plates (1) together limit a channel (26) which can convey moisture unintentionally passing the joint formed by the grooves and tongues downwards through the channel. |
