A novel and useful frame less 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.

System for plugging an opening, including: a plug element designed to cover said opening, a frame made up of at least four rails (1′) designed to be positioned inside the opening and including a first groove (22) formed on a front wall of each rail, and a seal (29),
said first groove (22) being designed to accommodate a substantially peripheral part (27) of the plug element, said seal (29) being designed to be accommodated with a tight fit in retaining means (34) inserted in said groove (22) and retaining said plug element on the frame.

A low-profile cladding system that can be readily applied to doors, windows, fixed light openings, or curtain walls where thermal performance is important. The cladding system utilizes a cladding member in combination with an L-shaped bracket to attach and secure the cladding member to a frame or sash. The cladding member is held to the frame or sash by tension or pressure between opposite ends of the cladding member. This tension is created by the L-shaped bracket in combination with the cladding ends as the L-shaped bracket engages one cladding member end and is pivoted into an indentation, or recess, in the frame or sash. The other cladding member end engages a groove along the side of the frame or sash opposite to the indentation.

Disclosed is a window or door frame assembly having a jamb extension coupling a window or door frame. The window or door frame has a longitudinal member having a surface defining a channel formed along the length of the longitudinal member. A jamb extension having a first face and a second face, a plurality of spaced apart grooves formed on the first face and extending along the length of the jamb extension, with the jamb extension configured to matingly engage the channel. A tooth coupled to the longitudinal member and configured to engage one of the plurality of grooves for coupling the jamb extension to the window or door frame. Also disclosed are kits and process for the window or door frame assembly.

A window system for use in windows, sliding glass doors, skylights, casement windows and other openings in a building. The window system enables different windows of the same building to be individually customized for different impacts of coastal area weather and security concerns and also have the same external appearance despite employing various window protection steps. Panels, interior or exterior, are secured to the header and sill. Windows may be covered with exterior panels or include interior panels or impact resistant glass when the window is high on the building, or where security is a concern Windows including casement windows and other building penetrations may also accommodate interior panels, in combination with exterior protection. The window framing may have a uniform exterior appearance, notwithstanding different levels of protection.
