A door assembly and a frame member for a door assembly. The door assembly may include at least one door panel and a door frame having a plurality of frame members including a header and a pair of side jambs. The invention may also be considered a frame member including a storage compartment. The frame member may include a core; and a top piece adjoining the core to form a structural member. The core and the top piece may be a composite of cellulosic material and at least one other material. The top piece may be a two-piece top piece and may include hollow cavities. Also disclosed are door jamb frame members and mullion frame members.

A fenestration system includes a chassis formed from left and right chassis stiles, and top and bottom chassis rails. The left and right chassis stiles having an outside longitudinal groove, an outside longitudinal ridge, an inside longitudinal groove and an inside longitudinal ridge. The top and bottom chassis rails having an outside longitudinal groove, an outside longitudinal ridge, an inside longitudinal groove and an inside longitudinal ridge. Outside stile covers are configured to engage the longitudinal outside groove and the longitudinal outside ridge of the chassis stile. Inside stile covers are configured to engage the inside longitudinal groove and the inside longitudinal ridge of the chassis stile. Outside rail covers are configured to engage the longitudinal outside groove and the longitudinal outside ridge of the chassis rail. Inside rail covers are configured to engage the inside longitudinal groove and the inside longitudinal ridge of the chassis rail.

A fenestration assembly includes a low-profile screen assembly including a fenestration frame and a sash movably coupled with the fenestration frame. The sash includes a daylight opening having a daylight opening profile. The low-profile screen assembly is coupled with one or more of the fenestration frame or the sash. The low-profile screen assembly includes a screen panel having a screen frame coupled along one or more of the sash or the fenestration frame, and the screen frame includes a screen frame inner perimeter. A screen membrane spans the screen frame and is coupled with the screen frame. The screen frame inner perimeter is outside of the daylight opening profile.

A door assembly is shown and described herein. The door assembly may include at least one door panel and a door frame having a plurality of frame members including a header and a mullion. The invention may also be considered a frame member. The frame member may be a mullion and include a core; and a two-piece top piece adjoining the core to form a structural member. The door assembly may further include at least one adjacent panel. The inventions disclosed are also applicable to jambs and window structures. Also disclosed are methods and assemblies for a mullion door frame member.

The present invention relates to a door frame, particularly a door frame for a pre-hung door assembly, which is foldable to minimize storage space and to allow for enhanced logistic efficiencies. The door frame contains parallel, spaced apart, vertical jambs and a horizontal header connecting the top ends of the jambs. Each of the jambs and the horizontal header contains a front section and back section that are hingedly joined so that then can be folded on to each other. The hingedly joined front and back sections allow the door fame to be foldable to minimize space occupied during storage.
