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.

A modular window assembly including a base frame, an interior frame cover, and an exterior frame cover. The base frame has a first complementary fastener located on an exterior face and a second complementary fastener located on an interior face. Each of the interior and exterior frame covers have a complementary fastener configured to releasably mate with the first and second complementary fasteners of the interior face and exterior face, respectively.

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.

Embodiments described herein may be directed towards a male and female gasket coupling for securing adjacent window frames. In accordance with the present disclosure, the male gasket may comprise a head portion that creates a seal inside a cavity of the female gasket. The female gasket may further be enabled to collapse on itself as it engages a surface of the male gasket. The seal may be maintained when the male and female gaskets move toward each other or when the male and female gaskets move away from each other due to fluctuations in temperature.

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.

Provided is a window system including a first window that extends in a first direction, and that partially overlaps a second window in the first direction. The second window extends in the first direction, and is offset from the first window in a second direction that is orthogonal to the first direction. The window system includes a connector that is configured to connect the first window and the second window, and that is disposed in an area between the first window and the second window in the second direction and where the first window partially overlaps the second window in the first direction.

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.

In accordance with the present disclosure, the male gasket may comprise a head portion that creates a seal inside a cavity of the female gasket. The female gasket may further be enabled to collapse on itself as it engages a surface of the male gasket. The seal may be maintained when the male and female gaskets move toward each other or when the male and female gaskets move away from each other due to fluctuations in temperature.

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.
