ABSTRACT:
A window design is provided with a pair of vertical jambs, a head jamb, a meeting rail and a sill. In one embodiment, an upper sash is secured in a fixed position between the vertical jambs, head jamb and meeting rail. Interior jambs are provided to extend outwardly from interior faces of the window frame and slidably receive a lower sash that is selectively moved between open and closed positions. A screen may be optionally secured to the exterior face of the window frame to allow the simultaneous use of the screen and the sliding lower sash. The window design retains a historic exterior appearance of the window while providing improved conveniences and durability.
