In various embodiments of the present disclosure, a fenestration apparatus is provided, including: a glazing comprising a LC panel having: a first glass layer; a second glass layer, and a liquid crystal cell therebetween; a frame, configured perimetrically around a corresponding perimetrical edge of the LC panel; and an attachment member configured to the frame, wherein the attachment member is configured to be removably fixable to an existing window, wherein the attachment member is configured to define a gap between the frame, the at least one LC panel, and the existing window.

A fenestration wall assembly includes a fenestration frame extending along a perimeter of the fenestration wall assembly. The fenestration frame includes a socket core having a first module socket configured to interchangeably receive service modules therein, and a second module socket configured to interchangeably receive service modules therein. The interchangeably received service modules include at least first and second service modules. Each of the first and second modules includes respective first and second module profiles. A panel having a panel profile is surrounded by the fenestration frame. The panel profile is isolated from the first and second module profiles.

Blast, ballistic, and entry resistant operable window systems include a sliding exterior glazing panel assembly, a sliding interior glazing panel assembly, an exterior frame assembly that receives the sliding exterior glazing panel assembly, an interior frame assembly that receives the sliding interior glazing panel assembly, an exterior gasket for placement between the exterior frame assembly and the wall of the building, a central gasket for placement between the exterior frame assembly and the interior frame assembly, and an interior gasket for placement between the interior frame assembly and the wall of the building. Methods of installation in a wall of a building are also provided.

A hybrid window frame assembly includes a primary window frame formed of a first material connected to a cladding frame formed of a second material. The cladding frame includes a peripheral channel defining a recess that receives a peripheral bead of the window frame to connect the cladding frame to the window frame. The hybrid window frame further includes injection block cutouts at each corner. Each injection block cutout exposes at least a portion of respective inner sidewalls of the channel and bead. The hybrid window frame assembly further includes injection blocks inserted in each injection block cutout. Each injection block includes at least one injection hole accessible from an exterior of the hybrid window frame assembly. The hybrid window frame assembly further includes sealant injected through the at least one injection hole of each injection block to seal respective corners of the window frame and cladding frame together.

Various embodiments herein relate to methods, structures, tools, installation systems, etc. for retrofitting a new electrochromic window in a pre-existing window recess. In many cases, the new electrochromic window is installed parallel to a lite of a pre-existing window, with the resulting structure including the new electrochromic window, the pre-existing window, and a pocket that forms between them. Installation of a new electrochromic window in tandem with a pre-existing window results in many benefits including improved insulation (e.g., due to the presence of the additional air pocket(s) and lite(s)), improved climate control (e.g., due to the ability to control the amount of sunlight entering the building via the electrochromic window), and enhanced aesthetics.

A main support frame is formed from sections of a plastic extrusion and has opposite side portions with peripheral recesses receiving an inner sash unit and outer sash unit each having a frame formed from sections of a plastic extrusion and supporting an insulated glass unit. Hinges support the dual sash units for pivotal movement between open and closed positions, and gear connected telescopic link members connect the main frame to the sash frames for simultaneous movement. A lock system includes a handle on the inner sash unit for moving straps with studs on the sash frames through a connector mechanism mounted on the main frame for simultaneously locking and releasing both sash units and for releasing only the inner sash unit. A screen and/or mini-blind can be supported between the sash units, and the window system with dual sash units may be constructed in various forms.

The present invention relates to an installation structure of a glass fixing gasket and a window glass panel fixing bracket, which fixes a window glass panel of a fixed window included in a sliding window system which comprises a segmented window frame and, more specifically, to an installation structure of a glass fixing gasket and a window glass panel fixing bracket, wherein the glass fixing gasket and the window glass panel fixing bracket are installed between a window frame portion which supports three sides (an upper surface, a lower surface, and one external side surface that is not a middle bar side surface) of a fixed window included in a sliding window and a window glass panel provided as a double-pane, in order to provide a sealing function for preventing ventilation and a function of stably fixing the window glass panel against high wind pressure (wind pressure resistance), and moreover, to ensure maximum heat insulation performance.

A double-skin fa?ade element comprises a planar outer glazing element and a planar inner glazing element which are held at a distance from one another in a thermally insulated surrounding frame profile; at least one pressure equalization device which is in air-conducting connection with the outside atmosphere and with a fa?ade intermediate space which is provided between the outer glazing element and the inner glazing element at least one drying device fillable with desiccant, is either located in the fa?ade intermediate space or is integrated into the surrounding frame profile and exchanges air with the fa?ade intermediate space; wherein the at least one pressure equalization device and the at least one drying device are positioned and dimensioned such that they do not extend into a transparent region of the fa?ade element. The at least one drying device is designed to make it possible to replace the desiccant.

A window frame insert for an existing window frame can comprise: a window pane comprising a thermoplastic polymer, wherein a length of the window pane is divided into a first portion and a second portion by a living hinge mechanism formed into the window pane that extends across a width of the window pane from one edge to an opposite edge such that the first portion can bend at the living hinge mechanism toward the second portion, and wherein an outer edge of the window pane removably attaches to the existing window frame, and preferably wherein the first portion and the second portion have a haze value of less than or equal to 5% as determined in accordance with ASTM D1003-13, preferably less than or equal to 2%.

A slim double-skin structure according to one aspect of the present invention may comprise: a window frame, an outer window sash frame provided on an outdoor side and coupled to the window frame, an outer glass provided on the outer window sash frame, an inner window sash frame provided on an indoor side and coupled to the window frame, an inner glass provided on the inner window sash frame, an awning film provided in a hollow layer formed between the outer glass and the inner glass to serve as a shading, and a case-type glass fixing frame which is provided in the outer window sash frame so as to be located in the hollow layer and fixes the outer glass to the outer window sash frame concurrently with building-in and guiding the awning film.
