CA 2093832

A window frame member is substantially pre- manufactured leaving only cutting the mortise and tenon ends of the rail and stile frame members along with cutting the glass stop to the required width. The pre-manufactured frame members include a continuous groove to receive removable glazing panel retention clips. A breather channel opening is cut in the mortise end of the stile frame member avoiding a separate drilling operation. The window frame is versatile and will accommodate multiple window accessories including a muntin grid and light control means such as a blind between two window units. An energy transmittance control system provides a balanced effective control of ultraviolet and near infrared light while maximizing transmission of the visible light. In a three glazing pane window assembly the outer pane includes two transparent silver metal layers while the inner pane includes one silver layer. One silver layer is provided on a stretched polyester film suspended between the outer and middle panes in a krypton filled insulated glass unit.
