A ready-to-install door system including, prior to installation, a frame including a hinge-side vertical bar attached at a top end to a horizontal bar that is further attached to a top end of a latch-side vertical bar, and a threshold portion that is attached to a bottom end of the latch-side vertical bar and a bottom end of the hinge-side vertical bar, a door rotatably attached to the hinge-side vertical bar of the frame, and at least one first removable spacer located at a first location of the door between the door and the frame, and configured to at least maintain a desired squareness of the door system prior to installation, wherein the first removable spacer is configured to be removed after the door system is installed.

Building systems including a frame with a horizontal member from which first and second vertical bars downwardly extend and a panel attached to the frame. The building systems include at least one of an integrated fastener cover that is moveable to a closed position that covers a portion of a fastener, a gusset assembly with a junction cover positioned at a corner junction between two adjacent portions of a panel, and hinge assemblies that reduce the sagging of a panel, such as a door.

A door assembly for selectively interlocking opposing doors each pivotably mounted at a hinge side thereof to a door frame so as to both open and close in the same direction includes a door handle assembly mounted to one door at a latch side thereof opposite the hinge side and carrying a first plurality of magnets, and another door handle assembly mounted to the other door at a latch side thereof opposite the hinge side and carrying a second plurality of magnets. The door handle assemblies are arranged relative to each other with the first and second pluralities of magnets aligned such each aligned pair of the first and second pluralities of magnets have opposite magnetic polarities, and the aligned first and second pluralities of magnets magnetically couple to each other as the door handle assemblies are brought into contact with each other.

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 glass panel unit includes: a first glass pane; a second glass pane disposed to face the first glass pane; a frame disposed between the first glass pane and the second glass pane and hermetically bonding a first peripheral portion of the first glass pane and a second peripheral portion of the second glass pane together, the first peripheral portion extending along an outer periphery of the first glass pane, the second peripheral portion extending along an outer periphery of the second glass pane; a vacuum space surrounded by the first glass pane, the second glass pane, and the frame; a gas adsorbent disposed in the vacuum space; and a thermal insulation layer disposed between the gas adsorbent and the second glass pane.

According to one embodiment, a flood vent panel includes a plurality of insulation pieces positioned together, and a panel frame surrounding the plurality of insulation pieces. The flood vent panel is configured to be coupled to a frame positionable on a structure, so as to at least partially block a fluid passageway through an opening in the structure. Each of the plurality of insulation pieces is separate from the other insulation pieces of the plurality of insulation pieces. Each of the plurality of insulation pieces is separate from the panel frame.

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 door system may include a threshold assembly having a base including a base drain channel having a major drain surface inclined from a second edge to a first edge thereof, a base drain hole defined in a second base sidewall to convey water from said base drain channel out through the second base sidewall to an exterior side, on a first base sidewall a first base seat configured for mating seated engagement with a first crown seat in a first seat connection, on the second base sidewall a second base seat configured for mating seated engagement with a second crown seat in a second seat connection, a crown supported by the base, the crown including a crown minor side above the first crown seat and a crown major side above the second crown seat, a crown gutter intermediate the crown minor side and crown major side, a gutter drain hole defined in the crown gutter to convey water into the base drain channel, the crown selectively installable on the base in a first position for in-swing movement of a door element or a second position for out-swing movement of a door element, the crown position selectable independent of the base positioned to convey water from the base drain channel to the exterior side.
