A prefabricated flashing product for an opening in an exterior surface of a structure includes a generally planar flange shaped to conform to the exterior surface, the flange extending outwardly from an entire perimeter of an aperture therein that corresponds to the opening, and a return that seals to the flange about the aperture and extends substantially perpendicularly therefrom toward an inward direction of the opening. The flange and the return are monolithically formed of a waterproof material. A method of integrating a fenestration product into an opening of an exterior surface of a structure includes inserting the flashing product described above into the opening, and inserting the fenestration product at least partially into the aperture of the flashing product.

A unified building opening extension system is pre-built offsite. In one embodiment, the extension system is a single sheet of metal cut, bent, and fixed in a predetermined size. The extension system provides an airtight, watertight assembly that is compatible with waterproofing and air barrier systems integrated with the assembly when the opening assembly (e.g. door or window), exterior insulation, and veneer are installed on the building wall. Water intrusion or leaks are resisted even under positive and negative air pressure events (i.e., winds and storms). A sill plate supports an opening assembly in a rough opening of the building and prevents water ingress into the rough opening.

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 splicing pipe for installing a door or window includes a first frame profile, a second frame profile, a heat insulation strip and at least two fasteners. A first clamping groove is formed on each of two sides of the first frame profile, and a second clamping groove is formed on each of two sides of the second frame profile. The first clamping groove and the second clamping groove are both configured to be connected to the door or window having glass. At least one of the first frame profile and the second frame profile on the same side is provided with an installation groove, and the fastener is inserted into the installation groove. The splicing pipe provided has the advantages of simple splicing operation and easy implementation, which can not only improve the splicing speed, but also guarantee the performance of the doors or windows after being spliced.

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.

A window wall system includes a sill receptor secured to an upper surface of a first floor slab, the sill receptor providing a base and an upright member extending from the base, a head receptor secured to a bottom surface of a second floor slab vertically offset from the first floor slab, and a glazing unit providing a sill, a head, and one or more panels extending between the sill and the head. A first hook defined by the sill is engageable with the upright member. When the upright member is received by the hook, the glazing unit is pivotable about the upright member toward a vertical orientation. A second hook is defined by the sill and receivable within a groove defined in the sill receptor when the glazing unit reaches the vertical orientation.

A window jamb extender includes a frame including: (i) a first leg including opposite inner and outer ends; and, (ii) a second leg connected to the outer end of the first leg and arranged transversely relative to the first leg. The first leg includes an outer face adapted to be abutted with an associated wall stud that partially defines a periphery of an opening in an associated wall structure. The first leg includes an inner face that is opposite the outer face and that is adapted to lie adjacent an outer peripheral wall of an associated window frame. The second leg includes an inner face adapted to lie adjacent an exterior face of the associated window frame. The window jamb extender further includes a J-channel portion including: (i) a primary flange that projects outwardly from the outer face of said first leg; and, (ii) a secondary flange that projects outwardly from the outer face of said first leg, wherein the secondary flange is spaced-apart from the primary flange.
