A security system and method for preventing unwanted passage through windows and doors of a building includes custom sizing and welding of hardened steel structures that mount into the door jam or window frame, on the inside of the door or window with the use of threaded fasteners. The custom assembled structure consists of an outer frame and horizontal and vertical pickets that may be formed of flat stock, hollow square or rectangular steel tubing or solid square hardened steel bars. The system and method involves specifically spacing the vertical and horizontal pickets so as to lineup with an ornamental structure on the window or door (e.g., grids) without obstructing the view of the door or window so that the steel bars of the security structure is essentially invisible.

A modular fenestration system includes a collection of standardized functional units such as double hung window units, casement window units, picture window units, transom units, and the like. The functional units all share common sightlines, common glass set-back, common interfaces, common design language, and are sized according to a unique modular or incremental sizing grid. The sizing grid specifies individual window units in terms of the rough opening size in which they are designed to be installed. Individual functional units are easily combinable in a vast array of combinations to create a large number of possible composite window units. The above attributes of the functional units ensures that the composite window units are architecturally pleasing and appear as though they were custom crafted. The system also includes a collection of interior and interior trim units in various architectural styles that can be attached to installed standardized functional units via the common interfaces to match the architecture of a particular home or building. A collection of matching architectural grilles and hardware also are provided, and the trim units, grills, and hardware are all historically and period accurate to represent a wide variety of architectures both past and present. Exterior and interior trim can be built up from a limited number of standard components that can be combined in a large number of ways to create a wide variety of trim profiles.

A muntin bar fabrication system can be used to efficiency produce a wide variety of different types of muntin bars, allowing the fabrication of both standard and custom muntin bar assemblies for doors, windows, and other fenestration products. In some examples, the fabrication system includes a muntin bar stock storage assembly that holds multiple different types of muntin bar stock. The system also includes a muntin bar stock extraction device that extracts one of the different types of muntin bar stock from the storage assembly and conveys the extracted muntin bar stock to a feed device. The feed device feeds the extracted piece of muntin bar stock into a cutting system that includes a multi-axis cutter. The cutting system that performs one or more cutting operations on the extracted muntin bar stock so as to fabricate one or more individual muntin bars from the extracted muntin bar stock.

For use in a window (10) that comprises a glazing unit (12) with at least one pane of glass, an assembly comprises a glazing bead (14) to extend around the periphery of the glazing unit (12) and defining apertures (17) at locations at which a glazing bar (16) is to fit, and at least one glazing bar (16) to extend across a face of the glazing unit (12), at least one end of the glazing bar (16) comprising a spring-loaded pin (20) to engage with an aperture (17) in the glazing bead (14). For example each glazing bar (16) may comprise spring-loaded pins (20) at each end, or alternatively a spring-loaded pin (20) at one end and a fixed projecting pin at the other end.

A door assembly includes a subdoor. The subdoor is selectively openable by pivoting relative to the main door and includes a window panel (typically glass). An array of screens is disposed in front of the subdoor and includes a plurality of relatively smaller screens that are physically separated from each other by a lattice. The structure of the door allows for greater ease of assembly while providing an appearance of having true divided lights. Related methods are also discussed.

The invention pertains to hermetically sealed glass using vacuum technology to remove still air, preventing the infiltration and exfiltration of heat through the installed glass in a modern window and/or door system composed of vinyl, wood, or other readily available substrate, thereby minimizing the negative impact of heat loss through the outer edges of the hermetically sealed glass, while also applying lengths of hollow vinyl, solid wood, or other readily available substrates to the exposed portions of the hermetically sealed glass to give the appearance of a window/door utilizing multiple single pieces of glass.
