A door assembly includes a doorframe, an insulated glazing unit (IGU), door skins, and a gas passageway. The IGU includes a substantially sealed IGU cavity and a hole communicating with the IGU cavity. The door skins are secured to opposite sides of the doorframe and have openings between which the IGU is provided. The gas passageway provides gas communication between the IGU cavity and the atmosphere outside of the door assembly. The gas passageway contains a gas passage conduit that includes a first end communicating with the IGU cavity through the hole and a second end communicating with atmosphere outside of the door assembly. The gas passageway may contain a gas passage conduit having a first end communicating with the IGU cavity through the first hole and a second end communicating with an air pocket, and a channel connects the air pocket with atmosphere outside of the door assembly.

Provided herein is a security door system having a door that includes a door frame comprising elongate door frame members, each having a first holding channel formed therein, and a clamping portion spaced from the first holding channel. The door further includes a mesh covering an opening enclosed by the frame. In addition to the above, the security door system includes a wall frame comprising elongate wall frame members operably coupled to the door frame by one or more hinge members, the hinge members facilitating pivotable movement of the door between open and closed positions and one or a plurality of security members configured to prevent or inhibit levering of the door relative to the wall frame.

This invention relates to doors having internal blocking components that reduce or eliminate telegraphing of the outer surface of the door facings. In particular, the invention relates to steel-edge steel doors that have internal solid wood blocks that have one or more integral cantilever beams formed into the blocks to interact with the adjoined oppositely arranged door facings in order to eliminate visually apparent door telegraphing. The blocks are modified to contain notches formed therein to form the cantilever beams.

A system including a door, a fastener, and a fastener retaining assembly is provided. The fastener is extending at least partially through an aperture in the door. The fastener retaining assembly includes a bracket and a retainer washer. The fastener retaining assembly is attached to the door and retains the fastener to the door. The retainer washer is disposed around the fastener and disposed between the bracket and the door.

A cabinet door includes a center panel with a flat member, and rods extending outwardly from first and second sides, and first and second ends. The cabinet door includes first and second stiles extending vertically and respectively receiving the rods extending from the first and second sides of the center panel. The first stile and the first side of the center panel define a first stile expansion gap, and the second stile and the second side of the center panel define a second stile expansion gap. The cabinet door also includes first and second rails extending horizontally and respectively receiving the rods extending from the first and second ends of the center panel. The first rail and the first end of the center panel define a first rail expansion gap, and the second rail and the second end of the center panel defining a second rail expansion gap.

A door, such as a storm door, has modular components for attaching the door to a door frame primary door and for ornamental and functional customization of the storm door and primary door in a convenient manner. A secondary door can be attached to a primary frame of a primary door. At least one anchor mechanism includes a post element attached to the primary frame and an anchor that can be selectively attached to the post element, wherein the anchor includes at least one of and ornamental and a functional element. A secondary door includes a secondary frame, at least one door slab, and at least one hinge coupling the at least one door slab to the secondary frame. A least one hole is formed in the secondary from so that the post element of the anchor mechanism can extend through the at least one hole and the anchor can be attached to the post element to secure the secondary door to the primary frame. The anchor also can be attached to the post when the secondary door is not secured to the primary frame.
