A double window construction and particularly an interior storm window construction wherein the framing or frame of the storm window is uniquely configured to provide both window support for the storm windows installed and also a smooth interior finish relative to the window opening being accommodated. The windows themselves are chamfered at their outer edges to provide for ease of installation in tracks or channels formed by resilient ribs. The sides of each rectangular storm window, as to the frame, are generally L-configured in transverse cross-section and include outwardly facing support ribs for providing support as well as space to receive a settable fluid substance such as silicone rubber, whereby to provide a secure support for the frame. The inner edges of the frame sides are preferably cut at the job site to abut directly the interior surface of the existing window frame.
An interior storm window construction including, in combination, a four-sided frame each side of which has a generally L-shaped transverse cross-section and is provided with a plurality of inwardly directed channel-forming ribs defining window-receiving channels and outwardly directed support ribs, said frame being provided with respective sets of fluid-admitting apertures between successive pairs of said support ribs, windows disposed in said channels, said frame being provided with an on-the-job-site-cut, installed-window-frame abutment edge disposed inwardly of said channel-forming ribs.
In combination, structure forming a window opening, an outer window frame installed at said opening, and in inner window frame installed at said opening inwardly of said outer window frame, said inner window frame comprising four sides forming a rectangle, each of said sides comprising an inner flange and an outer casement flange integral therewith in essentially 90.degree. relationship, said inner flange having inwardly directed mutually spaced ribs forming window-receiving channels and also outwardly projecting support ribs directed toward said opening, said inner flange also having a job-site-cut edge formed to abut said outer window frame, said window frames being constructed to receive windows.
A window frame side extrusion comprising a pair of elongate, integral, 90.degree.-related flanges, and plural sets of mutually spaced ribs means disposed on opposite sides of one of said flanges, said one flange being provided with respective sets of settable-fluid-receiving apertures disposed between opposite sets of said ribs.
