A fenestration assembly includes a fenestration frame and at least one panel movable between open and closed positions. A locking mechanism is coupled with the at least one panel and includes at least one latch and at least one latch fastener. The panel includes a secure configuration with the panel in the closed position and the latch coupled with the latch fastener. In the unsecure configuration one or more of the panel is in the open position or the latch is decoupled from the latch fastener. A status monitoring assembly monitors the secure and unsecure configurations and includes a sensor operator coupled with the latch, and a sensor coupled with one of the fenestration frame or the panel. In the secure configuration, the status monitoring assembly detects the sensor operator with the sensor if the panel is in the closed position and the latch is coupled with the latch fastener.

A window balance assembly may include a carrier, a spring element, and a mounting bracket. The spring element may include first and second portions. The first portion may be coupled to the carrier. The mounting bracket may engage the second portion of the spring element and may selectively engage the carrier.

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.

A sash guide for a hung window includes a plate having a first end and an opposite second end defining a longitudinal axis. The first end configured to mount to a side rail of a window sash and the second end having an outside surface spaced from the side rail in a transverse direction. The transverse direction being substantially orthogonal to the longitudinal axis. A cam block is disposed proximate the second end and between the plate and the side rail. An adjustment fastener is coupled to the cam block and configured to slide the cam block along the longitudinal axis such that the outside surface of the second end is adjustable along the transverse direction and in relation to the side rail.

This disclosure provides connectors for smart windows. A smart window may incorporate an optically switchable pane. In one aspect, a window unit includes an insulated glass unit including an optically switchable pane. A wire assembly may be attached to the edge of the insulated glass unit and may include wires in electrical communication with electrodes of the optically switchable pane. A floating connector may be attached to a distal end of the wire assembly. The floating connector may include a flange and a nose, with two holes in the flange for affixing the floating connector to a first frame. The nose may include a terminal face that present two exposed contacts of opposite polarity. Pre-wired spacers improve fabrication efficiency and seal integrity of insulated glass units. Electrical connection systems include those embedded in the secondary seal of the insulated glass unit.

A window vent stop is disclosed having a housing with a peripheral flange defining an opening, and a body depending from the peripheral flange. A stop block is mounted within the body of the housing for movement between an open position wherein a portion of the stop block protrudes above the peripheral flange and a closed position. A spring leg is located on a bottom end of the housing and flexes toward the housing when under compression, providing compressive force along a line parallel to a longitudinal axis of the housing when the window vent stop is inserted into an opening in a window sash. By applying force to further compress the spring leg, the vent stop can be readily removed from the window sash without damage.

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 window balance assembly may include a carrier, a spring element, and a mounting bracket. The spring element may include first and second portions. The first portion may be coupled to the carrier. The mounting bracket may engage the second portion of the spring element and may selectively engage the carrier.

A latch assembly for a fenestration assembly includes a keeper ridge configured for coupling with a fenestration frame. An assembly housing is configured for coupling with a rail of a sash, including upper or lower rails opposed to a check rail of the sash. A latch mechanism is movably coupled with the assembly housing. The latch mechanism is at least partially concealed with the rail. The latch mechanism includes a handle pivotally coupled with the assembly housing and a latch arm pivotally coupled with the assembly housing and operatively coupled with the handle. The latch arm includes a locking face configured for alignment with the keeper ridge.

A fenestration assembly includes a sash, a frame surrounding the sash, and at least one screen assembly mounted in at least one of: the top portion and the bottom portion. The frame includes a top portion, a bottom portion, and two jambs forming first slots extending lengthwise along at least a portion of the jamb. The first slots each include a screen edge retention feature. The screen assembly includes a roller assembly substantially hidden from view, a screen material attached to the roller assembly, and a plurality of raised features. Edges of the screen material extend into the first slots. The raised features are attached to each of the edges of the screen material. The raised features are configured to engage the screen edge retention features and retain each of the edges of the screen material at least partially within the first slot of each of the two jambs.
