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.

An engineered slope sill structure that include a first lateral edge next to the interior side of a building. The structure including a second lateral edge next to the exterior side of a building. The structure also includes a support surface extending from a first portion of the first lateral edge to a second portion of the second lateral edge where the support surface is designed to support a flow control device located in an opening formed by the building. The structure further includes a sloped surface located adjacent to the support surface and extending from a third portion of the first lateral edge to a fourth portion of the second lateral edge where the sloped surface has a first curved slope from the third portion of the first lateral edge to the fourth portion of the second lateral edge to direct moisture to the exterior of the building.

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.

A sliding door or window system includes a track. The track includes an outer housing; an inner housing within the outer housing; a guide body provided with the inner housing and configured to guide a sliding movement of a door or a window; and at least one adjustable body that is provided on the outer housing, at least partially within the inner housing, and fixed with respect to the inner housing in a vertical direction, the at least one adjustable body configured to change a height of the inner housing with respect to the outer housing by rotating, such as to change a height of the guide body.

A cladded wall system for constructing cladded cast-in-place concrete walls that are each integrated with lost forms comprising a self-supporting structure made of a plurality of prefabricated cladded panels (PCPs) constituting an exterior lost form, at least one architectural element constituting an interior lost form, and a plurality of concrete integratable connecting units by which each of said PCPs is connected to said interior lost form.

A door system and a method of making a door system including a metal door, a metal door frame for the metal door, and one or more door frame seals. The metal door and the metal door frame each include a steel outer surface with a first metal layer in contact with and that encapsulates or covers the steel outer surface, and a second metal layer in contact with and that encapsulates or covers the first metal layer. The first metal layer is different from the second metal layer. The first metal layer can be optional. The door frame seals are located on the metal door frame and provide conductivity between the metal door and the metal door frame. The door system preferably has an acceptable sound transmission class rating and RF shielding properties.

A sliding door or panel system is provided. The system can have a roller assembly that is mounted onto a sill. The system can have a moveable door or panel with a blade extending from a bottom rail of the door or panel. The blade can rest on the rollers and the rollers facilitate the door or panel moving longitudinally along the sill. The sill can be installed below a top surface of a floor, making the system less visible. The system can include a brush insert that protects against debris entering the sill. The brush insert can be removed from the sill to allow access to the rollers.
