A novel and useful frameless supplemental window for fenestration incorporating infiltration blockers suitable for use with existing windows. The supplemental window, in one embodiment, comprises plastic sheet material with bullnose edging around it. Corner braces add rigidity and strength to corners in several embodiments. An attachment mechanism secured either to the sheet material or the bullnose edge functions to fasten and/or seal the supplemental window to an existing window. Infiltration blockers fastened to the sheet or bullnose prevent or minimize air leakage around various window elements. The bullnose edging and infiltration blockers function to substantially enclose (i.e. trap) a volume of air between the window pane and the plastic sheet material. The supplemental window is configured such that the layer of air enclosed is of an optimum thickness within a preferred range of 0.15 to 0.75 inches to maximize thermal insulation properties of the supplemental window.

A supplemental window apparatus comprising: a constraint configured to be coupled to a window pane of an existing window and to provide a slot between the constraint and the window pane;a foot configured to be at least partially inserted into the slot to detachably couple the foot to the window p
1. A supplemental window apparatus comprising: a constraint configured to be coupled to a window pane of an existing window and to provide a slot between the constraint and the window pane;a foot configured to be at least partially inserted into the slot to detachably couple the foot to the window pane such that the foot extends substantially parallel to the window pane when at least partially inserted into the slot, wherein the foot is separately detachable from the window pane without detaching at least a portion of the constraint from the window pane;a spacer coupled to the foot and configured to extend at least partially in a direction perpendicular to the window pane when installed on the existing window; anda substantially non porous sheet coupled to the spacer and having a sheet area substantially similar to a window pane area defined by interior surfaces of a first window element holding the window pane, wherein the spacer and the foot substantially define a gap between the sheet and the window pane when installed on the existing window, and wherein the foot extends outward from the spacer toward the interior surfaces of the first window element. 2. The supplemental window apparatus as set forth in claim 1, wherein the constraint is configured to be attached to the window pane at a perimeter location of the window pane defined by the interior surfaces of the first window element holding the window pane when installed. 3. The supplemental window apparatus as set forth in claim 1, wherein the constraint comprises an adhesive along edges of the constraint configured to be located at a corner area of the first window element to form the slot, wherein the slot is defined by a volume between the constraint and the window pane where the adhesive is not present when the constraint is installed. 4. The supplemental window apparatus as set forth in claim 1, wherein the constraint is configured to allow at least a portion of the foot to extend out from under the constraint when inserted into the slot when installed. 5. The supplemental window apparatus as set forth in claim 1, wherein the constraint, when attached to the window pane, has a profile configured to allow a second moveable window element to be moved with respect to the first window element and over the profile of the constraint when the foot, the spacer, and the sheet are removed. 6. The supplemental window apparatus as set forth in claim 1, wherein the sheet is positioned substantially parallel to the window pane of the window when the supplemental window apparatus is installed in on the existing window. 7. The supplemental window apparatus as set forth in claim 1, wherein the foot, the spacer, and the sheet are constructed of a single continuous piece of material. 8. The supplemental window apparatus as set forth in claim 1 further comprising an edge seal coupled to the sheet and configured to substantially enclose a volume of gas between the window pane and the sheet when installed. 9. The supplemental window apparatus as set forth in claim 8, wherein the edge seal is configured to be folded on itself to form an open tube encircling a volume of air near a perimeter of the window pane when installed. 10. The supplemental window apparatus as set forth in claim 8, wherein the edge seal comprises one or more slits along a cross-section of the edge seal to allow a first portion of the edge seal to rest at a different level than a second portion of the edge seal when mounted on the existing window. 11. The supplemental window apparatus as set forth in claim 8, wherein the spacer comprises a formed edge configured for substantial conformity of the edge seal to the spacer. 12. The supplemental window apparatus as set forth in claim 8, wherein at least a portion of the edge seal is mechanically isolated from the foot, the spacer, and other portions of an edge seal. 13. The supplemental window apparatus as set forth in claim 8, wherein the edge seal has a cross-section comprising a first arc extending from the sheet, a middle portion configured to interact with at least a portion of the foot, and a second arc extending from the middle portion and configured to be constrained by at least one of the first window element or the window pane when installed. 14. The supplemental window apparatus as set forth in claim 1, wherein a first intersection between the sheet and the spacer is flexible, a second intersection between the spacer and the foot is flexible, or both the first intersection or the second intersection are flexible. 15. A supplemental window apparatus comprising: a constraint configured to be coupled to a window pane of an existing window, wherein the constraint comprises an adhesive along edges of the constraint configured to be located at a corner area of the window pane to form a slot between the constraint and the window pane, wherein the slot is defined by a volume between the constraint and the window pane where the adhesive is not present when the constraint is installed;a foot configured to be at least partially inserted into the slot to detachably couple the foot to the window pane such that the foot extends substantially parallel to the window pane when at least partially inserted into the slot, wherein the foot is separately detachable from the window pane without detaching at least a portion of the constraint from the window pane;a spacer coupled to the foot and configured to extend at least partially in a direction perpendicular to the window pane when installed on the existing window; anda substantially non porous sheet coupled to the spacer and having a sheet area substantially similar to a window pane area defined by interior surfaces of a first window element holding the window pane, wherein the spacer and the foot substantially define a gap between the sheet and the window pane when installed on the existing window, and wherein the foot extends outward from the spacer toward the interior surfaces of the first window element.
