Abstract: 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.

Abstract: Stops, glazing rings, windows, doors, etc. Some embodiments provide stops for securing window panes in windows. Some stops define elongated bodies with longitudinal axes, window pane-facing sides, frame member-facing sides, and sides at least partially set at acute angles to the other sides. Additionally, the frame member-facing sides also define grooves which are generally parallel to the axes and which can receive splines to seal the panes. Some stops have solid cross-sections which can be triangular. If desired, some stops are extruded and are orthogonally joined to one another to form glazing rings. These rings can be installed in windows, doors, etc. along with sealing splines to secure window panes against the window frame members. Moreover, they can comprise at least two stops. Furthermore, the frame members of embodiments are thermally broken.
