This invention relates to a “window construction” and
more particularly to a window having a sash provided
comprises window hardware associated with each of the
window sash and located in an outwardly opening
groove in the sash stiles 109 and 111 respectively. This
groove is indicated at 112 and opens out to an adjacent
part of the jamb liner 107 with a space 123 being pro
vided between the sash stiles 109 and 111 and the jamb
liner, as shown in FIG. 2.
,The hardware includes a friction member 113 having
an elongate U-shaped cross-section which is movably
