Abstract
Abstract The first and second vertical member of a storm window frame each include channels and vinyl sleeves for holding a double strength glass pane in position. One of the vertical members includes weather-stripping which protrudes from the frame in an exterior direction while the other vertical member includes weather-stripping which protrudes from the frame in an interior direction. In use, two or more of such panes are slidably mounted adjacent each other in thermal plastic tracks. The weather-stripping at the extreme ends of the window assembly create a seal between a window assembly and the track. The weather-stripping at overlapping portions of panes abutt against each other when the window is closed to create a seal thus permitting the creation of a still air space between an existing window and the storm window assembly.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
269 words
A storm window assembly comprising: a U-shaped track for mounting on a window sill into which a window may be slidably positioned including a base, at least first and second sidewalls extending perpendicularly from said base to form at least one channel, and a layer of adhesive material coupled to the underside of said base for securing said track to said window sill; and at least two individual overlapping windows which ride in said U-shaped track, each of said overlapping windows including: a pane of glass, a frame around said pane of glass including first and second vertical members, each of said vertical members having a notched channel into which said pane of glass is positioned, said first vertical member having weather-stripping means extending the vertical height of said first vertical member for operably engaging one of said track sidewalls, said second vertical member having weather-stripping means extending the vertical height of said second vertical member for operably engaging the weather-stripping means in a confronting vertical member of the overlapping window to create a seal between said overlapping windows when in the closed position, each of said weather-stripping means which engages the other of said weather-stripping means to create said seal being positioned on the side of its respective overlapping window that is closest to the other overlapping window, one of said first and second vertical members being equipped with handle means for opening and closing said window assembly, and sleeve means positioned between said notched channel and said pane of glass for operably securing said pane, the notches in said notched channel securely positioning said sleeve means therein.
Claim 2
Dependent Claim
