A method of installing a combination door unit into a threshold of a house, comprising placing a combination door unit within a threshold opening of a house surrounded by a plurality of house frame studs. The combination door unit comprises a door frame, a threshold door hingedly coupled to the door frame, and a secondary door. The secondary door is hingedly coupled to a mounting frame and the mounting frame, the door frame, and the plurality of house frame studs are aligned when the combination door unit is placed within the threshold opening. The method of installing the combination door unit may also comprise the steps of leveling the combination door unit, removing the secondary door from the combination door unit, driving a plurality of fasteners through the mounting frame, through the door frame, and into the house frame studs, and replacing the secondary door on the combination door unit.

A casement window operator includes a linear input mechanism configured to be mounted to a stationary frame of a casement window, a linear to rotary motion converter operably coupled to an output of the linear input mechanism, a gear reducer operably coupled to an output of the rotary motion converter, and a sash arm operably coupled to an output of the gear reducer to rotate in conjunction with the output of the gear reducer. The sash arm is configured to extend from the stationary frame of the casement window to a rotatable window sash of the casement window.

A window system includes a frame that includes a head, a sill, and opposing left and right vertical jambs, the left and right vertical jambs extending contiguously between the head and the sill, a fixed lite assembly fixed to the frame, a vent pivotably mounted to the frame and vertically offset from the fixed lite assembly, and a meeting rail interposing the fixed lite assembly and the vent.

A door assembly may include a first sidelite configured to be operably coupled to a first doorjamb, a second sidelite configured to be operably coupled to a second door jamb where the first and second sidelites are disposed in a common plane and define a door opening between the first and second sidelites, a first sliding panel, a second sliding panel where the first and second sliding panels are movable from a closed position disposing the first and second sliding panels to block access through the door opening and an open position in which the first sliding panel is proximate the first sidelite and the second sliding panel is proximate the second sidelite, a first partial door panel, and a second partial door panel. The first and second sliding panels are disposed in a second plane parallel to the common plane in both the open and closed position. The first and second partial door panels are operably coupled to the first and second sidelites, respectively, via hinge assemblies. The first and second partial door panels have a closed state in which the first and second partial door panels are each disposed in the common plane blocking access through the door opening, and an open state in which the first and second partial door panels are each disposed out of the common plane.

A fenestration assembly includes a fenestration frame and a sash movably coupled with the fenestration frame. The sash includes a daylight opening having a daylight opening profile. A low profile handle assembly is coupled with the fenestration frame and the sash. The low profile handle assembly includes a sash handle coupled with the sash and a handle socket in the fenestration frame. The handle socket is configured for reception of the sash handle. The low profile handle assembly has a composite handle profile including the sash handle received in the handle socket. The composite handle profile is outside of the daylight opening profile, and the daylight opening is unobstructed at least from the low profile handle assembly.

An escape system for descending a person from a window is disclosed. The escape system may be mounted above a window through which a person may egress and descend to the ground. The escape system includes a fenestration unit having a frame and a human support embedded into the frame in a stowed position. The human support carries a person during descent. A cable is wound about a shaft supported by the frame. The cable is connected to the human support. The escape system further includes a speed limiting device connected to the shaft that controls the speed of descent.

A closing body allows closing and opening an access opening or a passage of a room in case of a pressure difference between an interior and exterior of the room. A closing fitting set and a door leaf are disclosed, by means of which closing fitting set and door leaf a closing body can be formed. The closing body is in the form of a pivotable door, a pivotable window or a pivotable flap. A valve device is provided on the closing body, which valve device effects a temporary pressure equalization during the opening or closing of the closing body. The valve device is in the form of a valve flap, and a release mechanism is provided, which opens the valve device. A locking fitting is provided for the closing body, and the release mechanism is coupled, for actuation, to the locking fitting of the closing body.
