In a window assembly of the kind including at least two window sashes having inwardly facing surfaces and outwardly facing surfaces, said sashes being fitted into a perimeter frame formed by spaced apart longitudinal members joined at their ends to the ends of spaced apart transverse members, and means mounting at least one of the sashes for sliding movement in said frame in a longitudinal direction between a closed position and an open position and for inward movement relative to the frame, the improvement comprising a sash retainer mounted on each longitudinal frame member for longitudinal sliding movement relative to the respective frame member, each retainer having a longitudinal dimension about equal to the longitudinal dimensions of said slidable sash and being slidable between a first position coextensive with said slidable sash and a second position in which the retainer is longitudinally offset from said slidable sash, each retainer having a longitudinal fin overlying the inwardly facing surface of the respective longitudinal edge of said slidable sash when said sash and said retainer are coextensive to thereby provide support and sealing said surface; and manually releasable latches for releasably connecting said slidable sash to said retainers.

A storm window assembly comprising an upper sash and a lower sash both fitted into a frame construction which is adapted to be attached to a building coextensive with a prime window, said frame construction having two parallel longitudinal portions each of which includes inner and outer vertical flanges horizontally spaced apart to form a channel in which a vertical edge of the upper sash is accommodated when the upper sash is in its up position, each inner flange having a length approximately equal to the vertical dimension of the upper sash, a lower sash retainer carried by each longitudinal portion of said frame, each retainer being slidable vertically relative to said frame and each retainer including a vertical fin which overlies the inner surface of respective vertical edge of the lower sash when the lower sash is in its down position, the vertical length of each retainer being approximately equal to the vertical length of the lower sash;
