A sleek design with stationary upper sash and tilt-in bottom sash. The single-hung has multi-chambered construction and fusion welded corners. The lower sash opens for ventilation but the upper sash is stationary. The meeting rails and handle rail is reinforced with metal for rigidity. A full interlock at the meeting rail and a stepped frame design provides additional strength to the window.
Units contain 3/4″ insulated glass made with a superior insulating system. Finned weather-stripping helps control air infiltration. A groove around the master frame allows simple stacking and mulling of multiple units and the easy application of supplemental profiles.
