    Abstract: Window components are made by a fluid-assist injection molding process to reduce manufacturing costs and provide additional flexibility in the configuration of the window. In addition to the inventive product-by-process, two window configurations, a casement window and a picture window, are taught. The casement window has a frame with installation flanges and the window sash has integral mounting posts for handle hardware. Both the window frame and sash have encapsulated insulative air pockets.
