Abstract: A fenestration assembly includes a glazing unit includes a pane spacer between exterior and interior panes proximate glazing unit edges. A fenestration frame is coupled around the glazing unit and includes a frame core extending around the glazing unit. The frame core includes a unitary core wall including a composite material that is hollow and extends continuously from a core interior face to a core exterior face. A metal glazing cap is coupled with the frame core. The metal glazing cap having a cap end indirectly engaged with the glazing unit along the interior pane, and the cap end is remote from the pane spacer. Each of the core exterior face, the pane spacer and the metal glazing cap are thermally isolated from each other with the frame core including the unitary core wall.

Abstract: A retainer bar assembly for use with a door or window includes a retainer bar configured for slidable coupling with a fenestration frame and slidable coupling with a sash. A retainer bar handle is coupled with the retainer bar. A retainer bar fastener assembly includes a movable bolt movably coupled with the sash. The movable bolt is movable between a fastening configuration where the bolt is coupled with at least one of the retainer bar and the retainer bar handle and the retainer bar is fixed in an installed orientation relative to the sash, and a releasing configuration where the bolt is decoupled from one or more of the retainer bar and the retainer bar handle and the retainer bar is slidable relative to the sash.
