Thermally broken fenestration systems are provided that improve performance characteristics or combinations thereof, including strength and thermal conductivity. Embodiments disclosed include one or more fenestration frame assemblies, each having an interior frame member and an exterior frame member. The interior frame members and exterior frame members are coupled together via a plurality of bridges distributed along the length of the respective fenestration frame assembly. The bridges provide structural rigidity, while providing a plurality of air gaps between interior frame member and the exterior frame member to provide a thermal break.

A window system is disclosed. The window system provides improved visibility while protecting against wind and flying debris. In some embodiments, the window panel is made using insulated safety glass for added insulation from the elements and impact protection for wind borne debris. Fins (e.g., glass fins) are affixed to a vertical edge of each window panel to provide extra resistance to wind and flying debris while providing improved visibility over window systems that have metal frames. In some embodiments, the glass fins are made from laminated glass to achieve thicknesses of between two and three inches. In some embodiments, especially when the window panel is very tall, one or more horizontal fins are affixed to the inside surface of the glass for added strength.

A mullion assembly is provided for forming a window assembly, the window assembly comprising a first window frame and a second window frame coupled to a monolithic mullion core such that a distal portion of the first window frame is in contact with a proximal surface of the mullion core and a proximal portion of the second window frame is in contact with a distal surface of the mullion core. The mullion assembly further comprises a first and second female connector on a respective first and second side of the mullion core. A plurality of separate compartments is defined along a length of the mullion core vertically between the proximal and distal surfaces and laterally between the first and second female connectors. The mullion assembly further comprises first and second male connectors configured to engage the female connectors and seal the first and second sides of the mullion core.

Rotating door systems and methods for rotating a plurality of rotatable doors between a closed position and an open position are provided. Each of the rotatable doors may have a height measured in a vertical direction between opposing horizontal edges, a width measured in a horizontal direction between opposing vertical edges, and an axis of rotation centrally located between the opposing vertical edges. The rotatable doors may be rotatably coupled to an upper support at the axis of rotation via an upper pivot shaft and rotatably coupled to a lower support at the axis of rotation via a lower pivot shaft. The rotatable doors may be at least partially transparent. The rotation of one or more of the rotatable doors may be controlled by a controller.

A curtain wall or window wall for a building including a frame including a plurality of frame units composed of frame members, wherein the frame members comprise mullions. A plurality of infill panels are supported by and received within the plurality of frame units, and one or more thermally insulating elements. Each frame unit comprises a plurality of metal fastening elements for retaining infill panels within a corresponding one of the frame units. Each metal fastening element comprises a first end in contact with the mullions and a second end spaced from the first end.
