ABSTRACT:
A window sash construction is disclosed for wood framed windows in which a particular stile-rail and check rail member configuration is utilized to adapt a given sash to both vertical double hung and horizontal sliding installations, each sash unit being constructed with a common stile and rail sectional configuration such that all stile and rail members may be provided by two sash member types differing only in having two different end configurations and a common check rail shape in oder to assemble the universal sash units. A reversible common check rail configuration is also provided such that the sash units can be oriented in any mating arrangement while obtaining a proper seal. An antijam check rail seal installation is incorporated in one of the check rail surfaces in engagement when the window is closed, including a seal recess configured to allow an outwardly biased seal lip to cam itself back out of the unoccupied seal recess formed in the mating check rail surface in the event the check rails are displaced beyond their normal engaging position sufficiently for the seal to enter the opposing recess position.
