A wood-clad metal window frame is formed from four extruded aluminum sections to each of which is secured at its interior side edge a wood facing member. Each of the extrusions has formed thereon various lips and flanges which collectively define in the assembled frame an integral J-channel, an integral nailing and flashing flange, and a pair of integral jamb channels each adapted to receive and retain a conventional sash-supporting balance member. Carried within the frame, and concealing an interior portion of the head section of the frame is a sight baffle which has integrally formed therewith a weather stripping element positioned to sealingly engage a window sash installed in the frame. The wood facing members collectively define in the assembled frame an interior wood border which provides the frame with an all-wood interior appearance and further functions as a thermal damper to inhibit outward and inward heat flow through the frame. When the extruded aluminum frame is hung with conventional wood window sashes, the resulting frame-and-sash assembly has the desirable interior appearance of an all-wood frame and sash assembly, but may be fabricated and completely assembled at a fraction of the cost thereof.
