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.

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 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 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.

Embodiments of the disclosure are directed towards a composite stiffener that is incorporated into panelized products to create stronger bonding, greater adhesion between laminated layers and less warping sandwich panels. In addition, the resulting products incorporating composite stiffeners can be lightweight, yet stronger than other lightweight panels.

The invention refers to a door structure with thermal bridge brake defined by a door element mounted through hinges on a metal frame; characterized by such door element being defined by an inner metal panel and an outer metal panel bent in the shape of an idler; with celeron hearths provided on the perimeter as thermal bridge break element, defining a middle cavity filled with expanded polyurethane or other materials with isolating properties. Such inner and outer metal panels are joined on the perimeter, through welding points. The metal frame consists of a hollow outer metal frame and a hollow inner metal frame filled with expanded polyurethane or other materials with similar isolating properties, with a celeron hearth between them as a thermal bridge break element, joined by welding points in specific areas.

Embodiments provide a door body which opens and closes a front part of an article body, and which has a front panel that constitutes the front of the door body, a frame that supports at least a part of the outside edge of the front panel, and a back panel that constitutes the back of the door body. According to at least one embodiment, the front panel includes a hard coat laminated sheet; the hard coat laminated sheet has a first hard coat, a second hard coat, and a transparent resin sheet layer in that order from the surface on the front side. The first hard coat is formed from a coating material which contains (A) 100 parts by mass of a polyfunctional(meth)acrylate, (B) 0.01-7 parts by mass of a water repellant and (C) 0.01-10 parts by mass of a silane coupling agent and which does not contain inorganic particles, and the second hard coat is formed from a coating material which contains (A) 100 parts by mass of the polyfunctional (meth)acrylate and (D) 50-300 parts by mass of inorganic fine particles having an average particle diameter of 1-300 nm. This door body may have a display on at least a part of the front thereof.

A thermally-broken ornamental door includes a thermally-broken door and a thermally-broken jamb through which thermal transfer is greatly minimized. The thermally-broken door includes an outer panel and an inner panel that are minimally connected through a plurality of door bridging strips. The thermally-broken jamb includes an outer jamb frame and an inner jamb frame that are minimally connected through a plurality of jamb bridging strips. An insulating foam panel is present between the outer panel and the inner panel while an insulating foam core is present between the outer jamb frame and the inner jamb frame. A window assembly is hingedly mounted into the thermally-broken door and includes a retaining spacer frame that minimizes thermal transfer from an exterior environment to an inner window frame through a glass panel of the window assembly. The retaining spacer frame additionally provides structural support to the glass panel.

A door (10) comprising a door member having a rectangular frame (22) on which components forming the door member are assembled. The frame includes top, side and a bottom frame member (24, 26a, 26b, 28). The frame is sized and shaped to fit within an opening (P) in a sidewall (S) of a portable building (B). A foam panel (16) fits in the frame. Door panels (12, 14) are affixed to the outsides of the foam panel using an adhesive material. The result is a laminated door that can be lowered and raised for moving people and objects into and out of the building.
