The outer shell (3) is fixed to the wall (1) by local unions or fixtures. The air space between the shell and the wall, extends over the whole area of the lining and is open in all directions.S Pressure in the intermediary air space (2) under the shell, which acts as a pressure compensating cover, is maintained constant independent of wind speed. The wind pressure effects are dampened in apertures (6,7) which lead into the intermediary air space, and the air flow is restricted at the lower edge of the outer walls and the roof edge structures. |
