ABSTRACT:
A double-hung window has auxiliary vertical frames mounted on respective left and right stiles of inner and outer sliding sash units without providing respective outer peripheries of rectangular stile-rail assemblies of the inner and the outer sliding sash units with frameworks wherein the inner and the outer sliding sash units are respectively constructed so as to be slidably moved up and down freely through the auxiliary vertical frames along inner and outer guide recesses formed, respectively, in the left and right vertical frame members of a window frame, so that the outer surfaces of the glasses attached to inner and outer sliding sashes can be readily cleaned, and that the weight of the inner and the outer sliding sashes can be reduced so as to reduce the resistance to sliding thereof, thereby enabling the inner and the outer sliding sashes to be slidably moved smoothly.
