Insulating window panel
First Claim
1. An insulating window panel for simple assembly and removable installation by a user into a window recess comprising perpendicular side walls surrounding a window built into a wall to form a window opening, the insulating window panel comprising:
- a plurality of longitudinally extending frame pieces configured with joints for interconnecting the frame pieces as a frame around a window pane of an assembled window panel, wherein each one of the plurality of frame pieces is integral with a fixed longitudinally extending keder channel with a keder slot that opens out to an inside peripheral glazing side of each frame piece; and
the window pane comprising a flexible glazing sheet provided with a plurality of edges corresponding to the plurality of frame pieces assembled therearound, wherein a keder is formed on each one of the plurality of glazing sheet edges, and a corner cut spaces apart intersecting keder edges to enable window panel assembly by sliding all of the keder edges into keder channels of corresponding frame pieces.

Abstract
An insulating window panel for removable installation into a custom size window opening recess includes longitudinally extending frame pieces configured with joints for interconnecting the frame pieces to form a frame around a transparent flexible glazing sheet. Each frame piece has a longitudinal keder channel with a slot that opens out of a glazing side of each frame piece. The glazing sheet has edges corresponding to the frame pieces; and a keder formed on each of the edges, with a corner cut that spaces apart intersecting kedered edges, all being shaped and sized for sliding each keder edge into the keder channel of each corresponding frame piece such that the frame pieces form joints at the corner cuts and the frame pieces are pulled together at the joints by tension relative to the glazing sheet. Preferably a weatherstrip surrounds the frame perimeter with compressible fins for sealed but removable installation.

12. A method of providing a custom size insulating window panel for removable installation by a user in a custom size window opening around a built-in window, wherein the window opening comprises a recess defined by perpendicular side walls surrounding it, the method comprising the steps of:
-
the user determining a custom window size H×
W by making a plurality of spaced apart measurements Hi and Wi of window opening dimensions between opposed side walls thereof;an offsite manufacturer prefabricating custom size panel components for the user to assemble and install, wherein prefabricating comprises the method steps of; a) defining the custom window size dimensions H and W as the maximum one of the Hi measurements, and the maximum one of the Wi measurements, respectively; b) preparing a plurality of longitudinally extending frame pieces configured with joints for interconnecting the frame pieces to form a window frame, and wherein each one of the frame pieces has a longitudinally extending keder channel with a longitudinal keder slot that opens out of a glazing side of each frame piece; c) forming a compressible resilient weatherstrip that extends laterally outward to a width Lw from a weatherstrip side of frame pieces that form a perimeter of the window panel, the weatherstrip comprising a longitudinal fin that curves toward a front side of the frame pieces as it extends laterally, the frame front side being the side that faces away from the built in window when the panel is installed; d) cutting out a pane of flexible glazing sheet having a plurality of sheet edges corresponding to a plurality of frame pieces that will surround the pane, and dimensioned according to a predetermined relationship with the custom window size dimensions; e) making a kedered glazing sheet by forming a kedered edge bead on each of the cut glazing sheet edges, and by making corner cuts that space apart ends of intersecting keder beads, all being shaped and sized for sliding each keder edge bead in the keder channel of each corresponding frame piece such that the frame pieces form joints at the intersecting keder edges, and when fully assembled as a window frame, the frame pieces are pulled together at the joints by tension relative to the glazing sheet; f) configuring the frame pieces such that, when assembled, the window frame with a perimeter weatherstrip has outside panel dimensions that exceed the custom window size H×
W by a weatherstrip margin Wm that is no more than 1.5 times Lw; andg) bundling the custom size prefabricated frame pieces with weatherstripping and kedered glazing sheet for packing and shipping in a compact linear form; thereby providing on-site a kit that enables the user to complete the method steps of; h) on-site assembly of the custom insulating window panel by sliding kedered glazing sheet edges into weatherstripped frame piece keder channels and pulling the glazing sheet taut by aligning the frame pieces at the joints; and removable installation over the custom size built-in window by pressing the assembled insulating window panel into the window opening recess where it is removably held due to friction from the perimeter weatherstrip that is compressed by at least the weatherstrip margin Wm within the recess walls. - View Dependent Claims (13, 14, 15, 16, 17)
