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 door skin is provided that includes at least one inner panel, an outer body portion surrounding the at least one inner panel, and at least one contoured portion surrounding the at least one panel and interconnecting the at least one panel to the outer body portion. The at least one contoured portion is recessed from the at least one panel and the outer body portion and includes a center base portion that interconnects with the outer body portion via a first sloping portion and with the panel via a second sloping portion. The first sloping portion includes a first angled portion and a first bump. The second sloping portion includes second and third bumps.

The present application discloses a climate chamber comprising at least one housing comprising a door, with an interior volume which is closable with the at least one door, wherein the at least one door comprises an inner wall and an outer wall, wherein the inner wall is formed of a unitary and bendable base body which comprises a polygonal wall section enclosed by side regions, wherein from each of the side regions projects a tongue with its free end, wherein the tongue in a first edge is canted from the wall section into a first section to form a tray and wherein the free end of the tongue is canted back by a second edge into a second section in order to form a sealing seat into which a sealing can be set.

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.

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.

Composite door systems are provided for use in a protective barrier structure. The composite door systems provide for quick assembly, safety, security, and resistance to physical impacts or threats. The composite door systems may include a shell and a core that can be factory completed or finished on site. The shell may be shipped to the assembly location of the barrier structure, and the core may be formed on site by pouring liquid fill material into a cavity of the shell, which is allowed to cure into a solid fill material. Hardware housings may be operatively coupled to the shell that are made to receive door hardware but resist the liquid full material from filling the hardware housings. The shell, core, and/or hardware housings may provide resistance to damage, such as projectiles to provide enhanced security protection to the occupants or contents of the building structure.

A multi-threat security apparatus system for critical infrastructure protection is disclosed having an above-ground concrete base, a vertical post system adapted to be attached to the above-ground concrete base and to receive a plurality of louvers. The plurality of louvers provides the necessary ballistic protection for and air flow through to the critical infrastructure. The louvers may include a composite of aluminum foam, a resin impregnated ballistic material and an aluminum foam. The composite structure may be used on doors, panels or building walls.

A door skin is provided that includes at least one inner panel, an outer body portion surrounding the at least one inner panel, and at least one contoured portion surrounding the at least one panel and interconnecting the at least one panel to the outer body portion. The at least one contoured portion is recessed from the at least one panel and the outer body portion and includes a center base portion that interconnects with the outer body portion via a first sloping portion and with the panel via a second sloping portion. The first sloping portion includes a first angled portion and a first bump. The second sloping portion includes second and third bumps.

A door includes a first skin, a second skin, two stiles, a core, and a gas permeable membrane. The first skin provides a first outer door surface. The second skin provides a second outer door surface. The two stiles are disposed at least partially between the first skin and the second skin. At least one stile defines a vent therein. The core comprises a foam material and is disposed between the first skin and the second skin. The gas permeable membrane, which is permeable to gas but not to the precursors of a foam material, is disposed on the at least one stile covering the vent. The gas permeable membrane contacts the foam material in the core, and separate the foam material in the core from the vent.
