• The external wall grilles are rectangular aluminium louvered grilles for air supply or exhaust. They are manufactured from AlMgSi 0.5 aluminium. The grille is assembled from Z-profiles clipped onto aluminium louvre holders with a 3 mm blade pitch. This results in a 20 mm spacing between the blades. The louvre holders are laterally attached to the vertical perforated profiles of the fixed L-shaped frame. This frame, with a 26.5 mm stop and a 28.5 mm installation depth, is mitered at a 45° angle and assembled by pressing together with a clamping corner. The grille is fitted with an antistatic stainless steel mosquito net with 2.3 x 2.3 mm mesh, tensioned within the frame by a nylon cord. The grille is mounted by flush-mounting and fastening using standard dowels in the side of the wall duct. The grilles are finished in a natural anodised colour as standard.
