A window assembly for installing in a window framing (also referred to as a “window casing”) of a wall of a building. The window assembly is configured to have a frameless appearance when installed with the finish surround installed around the interior and/or exterior of the window. The window assembly also allows the glass panel to be removed with a minimum of removal of the finish surround, such as without removing any of the finish surround, or only removing the finish surround around several sides of the only one of the interior or exterior of the window. For example, in most cases, only the interior finish surround around the right side and left side of the installed window frame needs to be removed to remove and replace the glass panel. Furthermore, the window assembly includes an integrated drain for draining moisture which leaks into the window assembly.

An impact-resistant window may include features that reduce the forces exerted on the edges of related panes, thereby preventing breakage due to impacts. In a described embodiment, the in pact-resistant window comprises at least one pane made of a transparent material and a frame including a first frame portion, a second frame portion, and a third frame portion. In this embodiment, the connection between the first frame portion and the third frame portion may be configured to allow movement between the first frame portion and the third frame portion.

A system, device and method of framing an opening, such as a window, in a clad façade 12 structure to align the window units 22 to be positioned adjustably so that the exterior sight lines align the windows without custom fabrication of the clad façade. This allows irregular variations in the original building structure to be eliminated by a perfectly aligned façade. A frame 20 has wide flanges 40 to allow the defined inner box frame area 34 to be positioned and then the frame can be shimmed to that position. Sections of frame 20 are joined by an angled member 54 with flat portion which are received in slots 56 in frame sections at their edges.

A frameless window installation assembly is adapted to be mounted on a building wall, and includes a window sheet unit, and inner and outer bar holders. The window sheet unit has opposite inside and outside surfaces. The inner bar holder is made of metal, is disposed around a periphery of the inside surface, and is adapted to be secured to the building wall. The outer bar holder is made of metal, is disposed around a periphery of the outer side surface, is spaced apart from the inner bar holder, and is adapted to be secured to the building wall. The inner bar holder and the outer bar holder are not directly interconnected by a metal structure. The window sheet unit is secured between the outer and inner bar holders.

Window assemblies and methods for their construction are disclosed. In one aspect, the disclosed window assemblies include wooden side jambs connected to a non-wooden sill assembly via intermediately positioned end caps. In some examples, each end cap includes a main body and a step defined within the main body for supporting an end of the sill assembly, wherein the step extends at an oblique angle to a length of the side jamb associated with the end cap. The provision of an angled or obliquely oriented shelf eliminates the need to mill a similarly shaped structure within the wooden side jambs.

A fenestration system includes one or more of a light modulation controller or ventilation modulation controller. The light modulation controller is in communication with at least one light modulation element of a fenestration assembly having a frame and a panel. The light modulation controller includes a light prescription module configured to provide a specified light prescription for the building interior. A lighting difference module is configured to determine a prescription difference between the specified light prescription and ambient light. A dynamic light module of the light modulation controller operates the at least one light modulation element according to the prescription difference. The ventilation modulation controller is in communication with at least one operator configured to open and close the panel. A ventilation prescription module provides a specified ventilation prescription for the building interior, and a dynamic ventilation module implements panel closing and opening according to the specified ventilation prescription.
