ABSTRACT:
A sash and window frame assembly has a sash with opposite side stiles and a frame with spaced apart jambs which are fitted with the stiles by a tongue and groove interlock. This interlock which extends vertically and runs in a front to back direction of the window assembly resists inward pulling of the stile away from the jamb to which it is fitted.
