A windowed sash of the type having a window pane supported in a window sash. The window sash consists of elongated profiled polymeric members interconnected by weld seams at joints therebetween. The window sash is adapted to be mounted in a frame. Holes are provided in contact with the weld seams interconnecting the elongated profiled polymeric extruded members for distributing, at least partially, stress sustained by the window pane and the window sash when subjected to shocks, so as to prevent at least one of the weld seams, the elongated profiled polymeric extruded members and the window pane from cracking.
