    Patent number: 6749797
    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. An acrylic window pane is taught that mimics a glass block window.
