FRAMELESS SUPPLEMENTAL WINDOW FOR FENESTRATION
First Claim
1. A supplemental window apparatus comprising:
- a foot and an attachment mechanism, wherein the foot is configured to be detachably coupled to a window pane of an existing window by the attachment mechanism such that the foot extends substantially parallel to the window pane when installed on the existing window;
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;
a 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.

Abstract
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.

16. A method of making a supplemental window apparatus comprising:
-
providing a foot and an attachment mechanism, wherein the foot is configured to be detachably coupled to a window pane of an existing window by the attachment mechanism such that the foot extends substantially parallel to the window pane when installed on the existing window; coupling a spacer coupled to the foot, the spacer configured to extend at least partially in a direction perpendicular to the window pane when installed on the existing window; coupling a substantially non porous sheet to the spacer, the sheet 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. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
