A window insert assembly is disclosed for reducing window energy loss and for damping sound. Also disclosed are parts in a window insert kit to build a window insert and methods for installing the window insert into a window well. In one embodiment, the window insert comprises an outer frame assembly with a gasket frame seated in a gasket channel of the outer frame and planks of an inner frame seated in an inner channel of the outer frame assembly. The inner frame suspends layers of plastic wrap. In an alternative embodiment, the outer frame is in the form of a U-channel or adhesive foil with the gaskets adhered to its outer perimeter. In another embodiment, the outer perimeter of the inner frame comprises a stiffener groove. Here, the outer frame is in the form of a T-shaped stiffener with gasket adhered to its top.

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 smart window including a motorized shade is provided, particularly where the smart window includes a frame portion having a first subframe and a second subframe for mounting the smart window and routing the motor wirings. In a described embodiment, the smart window comprises: a frame portion including a wiring chase positioned internal to the frame portion and a glass portion. The glass portion may comprise a motorized shade, the motorized shade including a motor, a motor wiring, and a shade roll; a first pane of glass attached to the frame portion on an exterior side of the smart window; and a second pane of glass attached to the frame portion on an interior side of the smart window; wherein the frame portion surrounds the glass portion, wherein the motorized shade is attached to the frame portion between the first pane of glass and the second pane of glass by a hanging system, and wherein the motor wiring is positioned internal to the frame portion and the wiring chase.

A fenestration unit configured to support a shootbolt locking system includes a panel including a panel frame with a stile member and a rail member that are attached by a corner joint. The stile and rail members are elongate and extend along a respective linear axis. The stile member is configured to receive and support at least part of the shootbolt locking system. The stile member includes a stile end with a first wall, and the rail member includes a rail end with a second wall. The corner joint includes a first bracket and a second bracket that are attached together. The first bracket is disposed within the stile end. The first wall is disposed between the first and second brackets. The second bracket projects away from the stile member, and the second bracket is received within the rail end and attached to the second wall.

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 viewing window for insertion into a viewing opening in a ventilation and air-conditioning system and/or a climate chamber, the viewing window including two pane supports which can be connected to one another by a rotary joint that is prevented by a notched locking mechanism from accidentally coming loose.

A window device with a cementitious board as a frame material the device being a single or double window apparatus with an exterior configured with a cementitious board or structure and configured with such frames that are easily formed and readily adaptable to substantially any size or shape opening. The cementitious board window allows for a low maintenance, paintable or pre-painted panels that are moisture and rot resistant, are not susceptible to pest, and provide a surface which is durable over time, is non-combustible, and has materials with little environmental impact. The device is used with new or replacement windows for a commercial or residential structure.

A curtain wall having a frame construction with a plurality of glass elements and optionally panels arranged at a distance from each other in the heat flow direction, wherein a multifunctional glass element is arranged on the room side behind the main heat-insulating plane of the curtain wall, wherein the position of the multifunctional glass element can be modified in the vertical direction and/or the horizontal direction and the multifunctional glass element has at least two of the functions from the list comprising (A) anti-glare protection in the form of modifiable or switchable layers, (B) heating capacity at least in sections, (C) a configuration with integrated LEDs as room lighting, (D) a configuration as an information system, particularly as a screen, at least in sections, (E) a configuration with at least one integrated camera, and (F) a configuration with at least one integrated loudspeaker.

According to one example, a window system includes a window and further includes a frame that can be coupled to an opening in a structure. The frame includes one or more window seats and one or more moveable window stops. The one or more window seats can surround all or a portion of a periphery of the window. The one or more moveable window stops can be moved and coupled to different positions along a depth of the one or more window seats. The window includes a first window portion, a second window portion, and an interlayer positioned in-between the first window portion and the second window portion. The interlayer extends out of the periphery of the window.
