ABSTRACT:
Within an opening in a wall is placed a window or door having a frame, consisting of metal and plastic interlocked extrusions with a polyurethane core therein. The polyurethane core prevents penetration of condensate therethrough to the underlying casement consisting of wood studs, sheeting and dry wall.
Within the frame is a sash comprised of a set of metal and plastic extrusions which are interlocked and also form a cavity with a solid polyurethane core. The two extrusions have glazing beads to receive a glazing consisting of a double pane of glass separated to provide an insulating dead air space.
