Title: Sloped curtain wall structure

Abstract: A sloped curtain wall structure for buildings comprises an elongated, horizontal sill including a bottom wall and at least one upstanding side wall forming a gutter designed for mounting on a supporting base structure such as a vertical wall segment or a foundation wall. An elongated baffle is interconnected with the horizontal sill and is interlocked with side walls to substantially enclose the sill above the gutter and a plurality of rafters are connected through openings in the baffle by extruded anchors to the sill and supporting structure and slope upwardly to support glazing panels mounted in the frame work. Each rafter includes a gutter and a glazing pocket aligned with the glazing pocket in the baffle for receiving and supporting the edges of a glazing panel. The integral gutters on the rafters are adapted to collect any condensation from the panels and any leakage water and direct the collected liquid through the openings in the baffle into the gutter of the elongated sill for disposal outside the building.
