The channel (30) extends along a plane parallel with the plate facade plane and inside the facade plane, whilst the plate lower edge (23b) has a thickness which corresponds to the distance between the facade plane and the channel plane. At a horizontal seam between the two plates (23a, 23b), the upper of the plates (23b) has its inside plane located vertically over a channel (30) arranged along the upper edge of the lower of the two plates (23a). |
