An assembly for a door or window frame including an elongated sill and a corner key attached to each end of the sill. The corner key includes a water chamber for collecting water therein and a plurality of ports for diverting water from the water chamber outwardly through a drain port. The water chamber and plurality of ports are designed to temper a high-pressure gradient in the sill and effectively promote water egress away from the sill.

A fenestration unit includes a frame corner key that includes a corner key fluid outlet and a cladding having an aperture for the corner key fluid outlet. The fenestration unit also includes a weep drainage system with a fluid path defined from the frame corner key, through the corner key fluid outlet, and through the aperture to drain from the fenestration unit.

A one-piece sill pan flashing is provided with accordion sections enabling the flashing to be adjusted in width as necessary for installation in rough framing. The new flashing includes a sill plate cover with forwardly and downwardly inclined upper portions and lower portions extending downward from the upper portions. The accordion sections are incorporated integrally into the sill cover and are formed of narrow panels, flexibly connected along lateral edges to form V-shaped accordion folds having a series of ridges and valleys. The respective ridges and valleys are aligned in common vertical planes and are rounded through a transition curve at the front corners thereof. The flashing is injection molded in two end parts, each with one or more accordion sections. Center extensions can be used for extra wide window framing. The parts are permanently bonded and sealed at the factory and shipped and installed as one piece.

A corner key for a fenestration trim assembly includes a sloped bearing surface configured to bias a first lineal toward a second lineal about the longitudinal axis of the second lineal.

An assembly for a door or window frame including an elongated sill and a corner key attached to each end of the sill, where the corner keys each support a bottom end of a jamb. Each corner key includes a jamb-facing surface, a drain surface, and a sill-facing surface, the sill-facing surface extending between the jamb-facing surface and the drain surface. The corner key includes a chamber for collecting water therein and a drain port having an opening formed along the drain surface of the corner key, the drain port being in communication with the chamber for directing the water from the chamber out of the corner key.

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 gasket for an entryway is described that includes a compliant sealing portion having an uncompressed gasket thickness and a less compliant compression control portion having opposing exposed surfaces. A perimeter of the less compliant compression control portion is surrounded by the compliant sealing portion. A thickness of the less compliant compression control portion is less than the uncompressed gasket thickness.

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