A fenestration unit includes a first glass unit, a first panel frame, a second glass unit, a second panel frame, a sill flashing, and a frame. The frame includes a header, jambs, and a frame sill including a first track and a second track. The first panel frame and the first glass unit are slidable along the first track when positioned in the frame. The second panel frame and the second glass unit are slidable along the second track when positioned in the frame. The sill flashing includes a base extending under the first and second tracks and a wall extending upward from the base to inhibit moisture intrusion through the fenestration unit. The frame sill is removable from the frame without disassembling the sill flashing, the jambs, and the header.

A prefabricated integrated window and wall is provided. The prefabricated integrated window and wall includes a window frame, a wall, and a power system. The window frame is configured to hold a variety of different windows. The window frame includes a frame head and a sill. The frame head includes a channel. The sill includes tabs. The wall is configured around the window frame. The wall is configured to connect to the tabs of the sill and the channel of the frame head. The power system is molded into the window frame. A method of assembling the prefabricated integrated window and wall is also provided.

A sill pan is disclosed that is configured for use in spanning rough openings of various lengths. The sill pan includes a base, a pre-formed end flange integral with and extending upwardly from a side edge of the base, a first connector portion formed in the base adjacent to the pre-formed end flange, and a second connector portion formed in the base adjacent to an end opposite to the pre-formed end flange. The sill pan is configured be attachable to an adjacent sill pan with one of the first connector portion and the second connector portion.

A system and components for a window pan water dam system is disclosed. The object of the invention is to deflect water from the window base sill plate back towards the exterior drainage plain of the building envelope, thus ensuring water ingress does not occur through the sill pan area and the side walls of the opening.

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a sill, a head opposite the sill, a first jamb, and a second jamb opposite the first jamb forming a window cavity therebetween, the sill including a lower surface and an upper surface and one or more compartments therebetween; and a weep hood arranged in the sill and configured to allow water and air to exit the one or more compartments within the sill.

A flashing includes a first edge, a second edge opposite from the first edge, a first surface, and a second surface on an opposite side of the flashing from the first surface. The first surface and the second surface extend between the first edge and the second edge. The first surface includes a hydrophobic region and a hydrophilic region.

A sill track for sliding panels such as doors or windows in a door jamb or window jamb. The sill track mounts flush to the surrounding floors and has an integrated drainage system for preventing water from penetrating the sill track. The sill track comprises a base having walls to support flooring, a panel track for receiving a guide of a panel, such as wheels of a sliding glass door, and a weep channel wall forming a weep channel for draining water to below a top surface of the sill track. The walls of the base, the panel track and the weep channel wall are configured such that the flooring installed on the sill track, the panel track and the top of the weep channel wall are all flush with the surrounding flooring on the interior and exterior of the sill track.

A sill assembly that can include a sill and one or more threshold inserts. The threshold inserts can cover cavities within the sill. The sill assembly can optionally include a subsill, which can be a separate from or part of the sill. The subsill can include subsill cavities aligned over the sill cavities to form vertically-stacked pressure chambers. These vertically-stacked pressure chambers can include vertically-stacked pressure chambers positioned within the interior of the building, and vertically-stacked pressure chambers positioned within the exterior of the building. The sill assembly is so structured that different door types, such as swing doors, pivot doors, folding doors and/or sliding doors can be accommodated using the same sill and subsill by simply changing the threshold inserts. The sill assembly can have a minimal rise above the floor surface to meet regulatory requirements such as the Americans with Disabilities Act (ADA).

A flashing includes a first edge, a second edge opposite from the first edge, a first surface, and a second surface on an opposite side of the flashing from the first surface. The first surface and the second surface extend between the first edge and the second edge. The first surface includes a hydrophobic region and a hydrophilic region.

A water penetration prevention system includes an insert for being positioned along a track for a window, the insert having a first engaging portion disposed on a first side of the insert and a second engaging portion disposed on a second side of the insert. The system also includes a seal engaging member disposed between the first engaging portion and the second engaging portion, the seal engaging member being selectively positionable between a first position that a second position. The seal engaging member, in the second position, applies a force on at least one of the first side of the insert and the second side of the insert that causes the at least one of the first side of the insert and the second side of the insert to sealingly engage a corresponding one of the window and a vertical wall of the track.
