A sound damping door system having a door frame, a compression seal, a door slab, a bottom seal, and a concealed hinge assembly. The door frame includes male and female components adapted to engage each other in a rough door opening between first and second wall faces; and at least one isolation gasket adapted to be disposed between the male and female components. The compression seal is mounted to the door frame. The door slab includes an outer skin; an arched constrainment sheet inside the outer skin; a damping fill material inside the outer skin; and an acoustic insert inside the outer skin. The bottom seal is mounted to a bottom surface of the door slab such that the bottom seal is permitted to move relative to the door slab.

A metal door frame for a door opening comprising at least one first door frame segment for upper or side portions of the door opening, the at least one first door frame segment having a first molding flange, a first jamb face adjacent to the molding flange, and a first stop flange adjacent to the jamb face. The metal door frame includes at least one second door frame segment for upper and side portions of the door opening, the at least one second door frame segment having a second molding flange, a second jamb face adjacent to the molding flange, a second stop flange adjacent to the jamb face, a second stop face adjacent to the stop flange, and a third stop flange adjacent to the stop face. The metal door frame includes a thermally insulative layer between the first door frame segment and the second door frame segment.

Systems and devices for providing extension panels for doors. The extension panels may be physically coupled to the door using, for example, a bracket that may be coupled along a vertical edge and/or top edge or bottom edge of the door. In some instances, the bracket may include a channel that may be sized and shaped to receive and securely engage an elongated pin that may be physically attached to the extension panel. In some implementations, the bracket may include an H-shaped bracket that forms two cavities. One of the cavities may engage a portion of the extension panel and the other cavity may engage a portion of the door to physically couple the extension panel and the cavity.

A composite product includes gypsum in an amount of 60 to 90% by weight, fibers in an amount of 1.5 to 26% by weight substantially homogeneously distributed through the composite, and a rheology-modifying agent in an amount of 0.5 to 6% by weight. The composite is caused or allowed to cure to form a cured composite. The cured composite is a fire resistant component used in a fire-rated door core, a fire-rated door or a fire-rated building panel. The fire resistant component may include a building panel, a door panel, a door core, a door rail, a door stile, a door lock block, a door border, or a door insert.

A door includes a rectangular panel having a first face, a second face, and two pairs of opposing edges, in which the edges of each pair of edges are parallel and in which a first pair of edges is longer than a second pair of edges. The rectangular panel includes a layered composite material, in which a first layer of the composite material has a positive Poisson's ratio (PPR) and a second layer of the composite material is disposed in contact with the first layer and that includes a material having a negative Poisson's ratio (NPR). The door includes a hinge including plates joined together by a joint, in which a first one of the plates is attached to a first one of the edges of the first pair of edges and in which a second one of the plates extends beyond the first one of the edges. The door also includes a handle opening defined through a thickness of the rectangular panel.

A sanitary installation is described that comprises at least one sanitary space, which can be closed, and whose pivot door is configured as a double-leaf angled door having a leaf composed of a material that is preferably transparent over its full area and having a leaf composed of an opaque material.

A door include a first skin, a second skin, and a glazing unit. The first skin includes a first skin body portion, and a first flange portion extending inward from the first skin body portion. The first skin body portion has a first tip. A second skin includes a second skin body portion, and a second flange portion extending inward from the second skin body portion. The second skin body portion has a second tip. A glazing unit has an edge disposed adjacent to and between the first tip and the second tip. The first flange portion and the second flange portion provide an interlocking structure.

A door includes a door frame, first and second door skins having rectangular outer peripheries and inner openings, and a frameless glazed unit received at the openings. The door skins include exterior surfaces facing away from the door frame and opposite interior surfaces facing and secured to opposite sides of the door frame. The exterior and interior surfaces of the first and second door skins establish integral lips and grooves of the first and second door skins Opposite sides of the frameless glazed unit directly contact and are sealed by the integral lips and sealant and/or adhesive contained in the grooves of the first and second door skins.

A door includes a single panel folded to form a latch face and first and second main faces of the door. The door preferably further includes edge tabs folded to form upper, lower and hinge faces of the door. The panel is preferably a composite panel including an inner metal sheet, an outer metal sheet, and a plastics core material between the metal sheets.
