Abstract: Extruded aluminum members are provided in a framework for supporting glazed panels in an inclined or sloped glazing structure. A sill at the lower edge of the glazed panels has an upper surface that defines a raised portion of the convex contour to receive a concavely contoured support bar at an angle alpha which may very depending upon the particular installation. The upper edge of the glazed roof structure is supported by a header which is designed with a ribbed flange that can be combined with a mating top bar of L-shape cross section in a variety of positions to accommodate different angles alpha between a vertical wall against which the inclined structure is mounted and the plane of the sloped glazing structure itself.
