Prior to dry-in of a building, constructing an outer frame within an external opening of the building by attaching a top piece to a top, attaching a first side piece to a first side, attaching a second side piece to a second side, and attaching a bottom piece to a bottom of the building opening. After constructing the outer frame within the external opening of the building, the method includes mounting glass to glass receiving surfaces of the top piece, the first side piece, the second side piece, and the bottom piece. After dry-in and interior wall finishing of the building, the method includes attaching a plurality of inner base caps to an interior of the outer frame. After dry-in and exterior wall finishing of the building, the method includes attaching a plurality of outer base caps to an exterior of the outer frame.

Fenestration unit frames with integral mull posts and methods of making the same are described herein.

Disclosed is a sill assembly and sill that can be positioned continuously under doorways with swing doors, sidelites, and vertical door frame members such as vertical jambs, and mull posts, or the vertical members of sidelites. One variation of the sill assembly can be used for inswing doors while another can be used for outswing doors. The sill assembly includes a backstop and optionally can include end dams. These in combination with the structure of the sill assembly shed water away from the building structure and allow for the possibility of the sill assembly being installed without an additional sill pan or flashing. The sill assembly can optionally include one or more thermal breaks. The sill assembly can be structured so the thermal breaks of the door, sidelites, and vertical door frame members all align with the thermal breaks of the sill assembly.

A dead stop type projection window assembly includes a free-standing frame and at least one independent insert window. The free-standing frame includes a top member, a base member spaced below the top member, at least two mullions vertically extending between the top member and the base member and spaced apart to form an insert window opening therebetween, and a stop extending along a perimeter of the insert window opening. The insert window is secured to the free-standing frame at the insert window opening. The free-standing frame further includes at least one preformed seal member engaging the insert window to seal closed the window frame opening with a wind/water tight seal. The preformed gasket can extend from the stop to the insert window and/or can extend from at least one of the mullions to the insert window.

A dead stop type projection window assembly includes a free-standing frame and at least one insert window. The free-standing frame includes a top member, a base member spaced below the top member, at least two mullions vertically extending between the top member and the base member and spaced apart to form an insert window opening therebetween, and a stop extending along a perimeter of the insert window opening. The insert window is secured to the free-standing frame at the insert window opening and is sealed at the stop with sealant to close the insert window opening. The free-standing frame also includes a sealant dam extending from the stop and engaging the insert window to resist flow of the sealant toward the window frame opening between the stop and the insert window.

The present disclosure provides a frame component for a window or door that employs composite materials in a manner that is sufficiently structurally strong yet resists degradation due to unfavorable environmental conditions. In at least one embodiment the present disclosure provides a mullion for a frame for an opening having a core assembly having a longitudinally extending core and at least one end block, a first surface of the end block abutting a first end of the longitudinally extending core to result in the core assembly having a radial surface extending radially about the core assembly; and a longitudinally extending outer sheath, the longitudinally extending outer sheath enveloping the radial surface of the core assembly, an inner surface of the longitudinally extending outer sheath bonded to the radial surface of the core assembly in a continuous manner.

A security panel framing system having a base frame; a base plate under a base frame bottom side, the base plate having a stopper; a hollow inner channel defined by the base frame; a wedge having a wedge top side, and a wedge bottom side; a wedge wall extending between the wedge top side and the wedge bottom side; a reinforced end at the wedge bottom side; wherein the reinforced end and a bottom wedge lip are configured to be held in place by the stopper; a cap configured to be associated with the wedge; and wherein the wedge is configured to sit at a base plate front side leaving a gap between the wedge back side and the base frame, the gap being configured to receive a security panel, such that the security panel is snugly encased by the base frame and the wedge.

Compound fenestration assembly mull joints, compound fenestration assemblies using those mull joints, and methods of making and using the same are described herein. The mull joints in compound fenestration assemblies as described herein use universal joining strips to form both sides of a mull joint, as well as other universal components such as, e.g., corner gussets, locator plates, end plugs, seal members, etc. that may be used as needed to form mull joints as required in a compound fenestration assembly.

A glazing system for holding glazing units to a frame member has an aluminum pressure plate and a composite plate co-extruded from a plurality of polymers and having a pair of gaskets and a central isolator. A pair of polymer extrusions extend from the isolator and have ledges at the end that embrace and seal against the metal plate. The metal and composite plates are coupled together by a pair of ribs extending from the composite plate into a pair of slots in the metal plate.

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.
