Casement window system and components and hardware therefor

Interlock cover extrusion

A method of fabricating a rectilinear window frame comprising cutting a length of extruded frame profile having a body portion and an integral nailing fin into four lengths from opposite sides of the profile at forty-five degrees (45&deg;) with the cuts meeting at a point intermediate the width of the nailing fin, then assembling the four sections into the rectangular frame. The invention is also directed to frames produced by such method.

Window frame and method of fabricating same

Sill frame extrusion

Window sash extrusion

A window frame incorporating a sliding sash, the frame providing increased water resistance by incorporating an integral J-rail return, the return portion of which has a double wall to provide a depending trough at the bottom of the frame with a wall forming a chamber including the trough, opening from the bottom of the frame into the chamber and from the bottom of the trough to the exterior to provide increased dam height against water backing up and spilling over the interior sill of the frame.
