A retrofit window kit includes a plurality of magnetic sash elements configured to be positioned at one or more locations on an interior perimeter of the sash and a corresponding plurality of magnetic window grid elements each configured to magnetically couple to one of the magnetic sash elements and constructed as a clip or a cap that fits over and frictionally attaches to an exterior end of a window grid muntin.

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.

Exposed edge margins that are formed when a window film is installed on a glazing surface using an aqueous fluid as a lubricant are immediately covered by a series of elongated members that adhere to one or more of the window film or the surrounding frame. The elongated members provide concealed gaps or channels that allow for the slow evaporation of the aqueous fluid as the adhesive on the window film slowly wets and develops maximum bond strength to the glazing surface. The elongated members are preferably left in place as an inner frame. The inner frame device and method can be deployed in attached an light control film to a window, such as UV protective film, IR rejecting film, absorbing film and daylighting film.

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 window with display function includes a window frame, a window body embedded in the window frame, a flexible display screen, an electronic element. The window body includes a first glass layer and a second glass layer spaced from each other. The flexible display screen is between the first glass layer and the second glass layer. A house using the window is also related.
