A kit for sealing an architectural opening, such as a window or a door, is provided. The kit includes a clear vinyl sheet having a thickness of at least 1 millimeter and a magnetic strip. An adhesive backing extends along one side of the magnetic strip such that the magnetic strip is adhesively mountable to the vinyl sheet. The kit enables a consumer to easily seal the architectural opening by adhering the magnetic strip to the vinyl sheet, and then magnetically attaching the sheet over the architectural opening, thereby sealing the opening. The thickness and material of the sheet provides enhanced ease of use and durability.

A press-fit window insert configured to provide secondary protection to an existing window, having a carrier, a fin, and a fastening clip. The carrier includes a substantially rigid framework having channels within the framework configured to securely accept one or more attachments. The fin extends from the carrier and includes a substantially flexible blade extending from a base portion of the fin. The base portion of the fin is configured to interlock the fin to the carrier. The fastening clip includes a substantially rigid brim extending from a base portion of the fastening clip. The base portion of the fastening clip is configured to interlock the fastening clip to the carrier.

A novel and useful frameless supplemental window for fenestration 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. The bullnose edging functions 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 trapped air 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.

Aspects disclosed herein relate to a fenestration supplement system and methods of using such a system. In one aspect, the fenestration supplement system includes a fenestration supplement frame member that is configured to accept three or more fenestration supplements. In another aspect, a fenestration supplement frame member has opposing first and second ends that each receives fenestration supplements, connectors and/or hardware (such as mounting hardware). In yet another aspect, a fenestration supplement frame member includes specially shaped grooves that can accept and retain different types of connectors.

In an aspect, an insulation kit for insulating an interior side of a window is provided. The window includes a window pane and a window frame having a window aperture in which the window pane is mounted, and at least one surface on the interior side of the window which extends around an exterior edge of the window aperture. The insulation kit includes a adhesive member and a sheet of insulating, biodegradable film sized to be mounted to a surface of the window frame by the adhesive member so as to cover the window aperture, and being heat shrinkable to form an airtight seal, insulating the window pane on the interior side of the window. The sheet of film is constructed to be mounted to the at least one surface of the window frame for a period of at least four months before degradation of the film occurs.

A window insulation apparatus includes a cylindrical core having opposite top and bottom ends. A plastic sheet has opposite top and bottom ends and is pleated along parallel fold lines that extend parallel to the top end of the sheet to form a folded sheet. Adhesive is applied adjacent the top end of the sheet. The folded sheet is wound around the cylindrical core so that the top end of the folded sheet is near the top end of the cylindrical core. A housing receives the core and the sheet wound on the core. The housing includes an elongate opening from which the sheet can be unwound. A cutting assembly is mounted to the housing substantially adjacent the elongate opening and can be moved parallel to the opening for cutting the sheet that has been dispensed from the opening.
