The member (1) has an upper wall (2), a front wall (3), a rear wall (5), and side walls (4a,4b). A downward sloping surface is formed to the upper wall. Ribs (10), which form ducts (12) sloping downward towards the front wall, protrude from the downward sloping surface. An independent claim is also included for an architectural structure e.g. house. |
