ABSTRACT:
A window construction comprising a master frame and a pair of glazed window sashes which are double-hung in the window frame for normal operation and are provided with means to permit inward tilting of the sashes for cleaning and servicing of the same as may be required. The master window frame and both of the sashes mounted therein are each formed of an assembly of sections having the same hollow cross-sectional shape throughout the lengths thereof to provide not only the master frame but also each sash with a perimetrally continuous plenum of confined air which effectively serves as a thermal insulating barrier. Each of the window sashes is fitted on its opposite side edges with hollow thermal insulating spring-pressed weatherstripping members which respectively resiliently engage and made weather-tight contact with vertically extending runways provided therefor in the opposite side rail members of the master frame.
The window frame is provided in its opposite sides with vertically extending spring-pressed parting strips which project internally of the window frame into positions intervening the sashes when the same are in their normal double-hung condition and are adapted to be pressed outwardly from their said sash-intervening position against the restraining bias of their springs to completely clear the window opening for inward tilting of the outside window sash. Latching means are provided for releasably holding the window sashes in their normal positions for relative vertical movement thereof within the master frame.
By virtue of these spring pressed parting strips the master frame is adapted to receive therein a pair of window sashes which are of the same size and shape and so are interchangeable for installation as either the inside or the outside sash of the window assembly.
