REINFORCED WINDOW ASSEMBLY Abstract of the Disclosure A sash assembly for a glazing panel. The sash members of the assembly are formed with a concave inner surface which con- tains a rigid reinforcement member. The reinforcement member interlocks with retainers which extend from the inner surface of the sash member to provide rigidity to the sidewalls of the sash member when it supports the glazing panel. The sash members are preferably of extruded construction and are formed with an open compartment which allows for greater ease and speed of production. Such open compartment construction permits the use of extrusion dies and downstream forming equipment which are simpler and less expensive than conventional equipment. Also, cooling and forming of the extruded material is speeded since all sides of the sash member may be uniformly cooled rather than only the exterior of an enclosed compartment. This also yields a sash member having a more uniform shape and less internal stress. The rigid support inserted within the sash member is used to pull the side walls of the sash member together and provide strength without the necessity of utilizing webbing between the side walls which forms an enclosed compartment.
