Abstract
Abstract A system for double glazing existing panes in windows or the like in which a pane of translucent or lightaltering material is cut to the shape of the exposed surface of an existing windowpane within its sash. The additional pane is secured to the existing pane through the use of magnetically intermateable spacer strips which are secured to the added and existing panes around their outer periphery by means of an adhesive. The intermateable spacer strips are of a thickness which allows for separation of the two panes by a sufficient distance to create an air space therebetween to enhance the insulating properties of the structure. A thin flexible strip of decorative material is secured to the surface of the attachable pane opposite the existing pane along its periphery so as to overlap the adhesive on the opposite face of the attached pane while extending outward to overlap the inside edges of the sash and thereby additionally seal and insulate the area around the outer periphery of the attached pane. A method for applying the attached pane to the existing pane is also disclosed.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
262 words
In combination: a window having a sash and at least one fixed pane of flat translucent material surrounded by and fixedly mounted along its edges within said sash, an insulating pane of flat, translucent material of approximately the same shape and of a size slightly smaller than the exposed surface of said fixed pane so that said insulating pane fits interior to said sash, insulating strip means for holding said insulating pane to said fixedly mounted pane including a first insulating spacer strip means having one surface bonded to and along the periphery of said fixed pane and an oppositely facing selectively engageable surface and a second insulating spacer strip means having one surface bonded to and along the periphery of said insulating pane and an oppositely facing selectively engageable surface which intermates with the engageable surface of said first spacer strip means to hold said insulating pane in spaced parallel relation to said fixed pane, said insulating spacer strip means being of material having a low thermal conductivity being sufficiently thick to create an air space between said panes, an insulating strip adhesively mounted to the outside edges of said insulating pane so as to be removable therewith, said insulating strip having a portion which overlaps said spacer strip on the opposite side of said pane and a flexible portion extending outward around the periphery of said insulating pane and into overlapping engagement with said sash so as to create an enclosed air space around the outer periphery of said insulating pane in addition to the air space between the panes.
Claim 2
Dependent Claim
262 words
In combination: a window having a sash and at least one fixed pane of flat translucent material surrounded by and fixedly mounted along its edges within said sash, an insulating pane of flat, translucent material of approximately the same shape and of a size slightly smaller than the exposed surface of said fixed pane so that said insulating pane fits interior to said sash, insulating strip means for holding said insulating pane to said fixedly mounted pane including a first insulating spacer strip means having one surface bonded to and along the periphery of said fixed pane and an oppositely facing selectively engageable surface and a second insulating spacer strip means having one surface bonded to and along the periphery of said insulating pane and an oppositely facing selectively engageable surface which intermates with the engageable surface of said first spacer strip means to hold said insulating pane in spaced parallel relation to said fixed pane, said insulating spacer strip means being of material having a low thermal conductivity being sufficiently thick to create an air space between said panes, an insulating strip adhesively mounted to the outside edges of said insulating pane so as to be removable therewith, said insulating strip having a portion which overlaps said spacer strip on the opposite side of said pane and a flexible portion extending outward around the periphery of said insulating pane and into overlapping engagement with said sash so as to create an enclosed air space around the outer periphery of said insulating pane in addition to the air space between the panes.
Claim 3
Dependent Claim
28 words
The combination according to claim 1 wherein said selectively engageable surfaces of said first and second spacer strip means consist of an interlocking mesh of minute plastic projections.
Claim 4
Dependent Claim
28 words
The combination according to claim 1 wherein said insulating strip is of vinyl material selectively coated with adhesive along an area overlapping the periphery of the insulating pane.
Claim 5
Dependent Claim
189 words
In a window system the combination comprising: a window having a sash and at least one fixed pane of flat translucent material surrounded by and mounted along its edges within the sash; a supplemental pane of flat translucent material of approximately the same shape and of a size slightly smaller than the exposed surface of said fixed pane; means for holding said supplemental pane to said fixed pane including (a) a first strip means disposed about the periphery of said fixed pane and having an adhesive-bearing side bonded to said fixed pane and a magnetic side strip opposite said adhesive side, and (b) a second strip means bonded about the periphery of said insulating pane and having a magnetic side which is selectively intermateable with the magnetic side of said first strip means to hold said panes in spaced, parallel relation while allowing selective disengagement thereof, and a flexible insulating strip having a portion adhesively bonded about the periphery of said supplemental pane and a flexible portion extending therebeyond so as to overlap and seal an enclosed air space about the periphery of said supplemental pane within said sash.
Claim 6
Dependent Claim
189 words
In a window system the combination comprising: a window having a sash and at least one fixed pane of flat translucent material surrounded by and mounted along its edges within the sash; a supplemental pane of flat translucent material of approximately the same shape and of a size slightly smaller than the exposed surface of said fixed pane; means for holding said supplemental pane to said fixed pane including (a) a first strip means disposed about the periphery of said fixed pane and having an adhesive-bearing side bonded to said fixed pane and a magnetic side strip opposite said adhesive side, and (b) a second strip means bonded about the periphery of said insulating pane and having a magnetic side which is selectively intermateable with the magnetic side of said first strip means to hold said panes in spaced, parallel relation while allowing selective disengagement thereof, and a flexible insulating strip having a portion adhesively bonded about the periphery of said supplemental pane and a flexible portion extending therebeyond so as to overlap and seal an enclosed air space about the periphery of said supplemental pane within said sash.
Claim 7
Dependent Claim
