Hollow core door apparatus for preventing the build up of pressure in a room having a register through which air flows into the room and the door includes an inside door skin and an outer door skin, and the door skins includes openings through which air flows and panels disposed in the openings to define the amount of air flowing through the openings in the skins. The door also includes at least a single fixed panel and a movable panel, both of which panels include openings through which air flows when the openings in the panels are aligned and which air flow is restricted when the openings are misaligned. The inside and outside panels have peripheral openings defined between the openings in the skins and the panels disposed in the openings and which peripheral openings define areas at least as great as the area of the openings in the fixed and movable panels, and the openings in the fixed and movable panels are offset from the peripheral openings to provide for a non-linear flow of air through the door to prevent the build up of pressure in the room and to restrict the non-linear air flow through the door when the openings in the fixed and movable panels are misaligned. An embodiment combining a noxious gas absorbent material with the pressure build up prevention capability is also illustrated.

A galley insert includes an oven housing defining an interior cavity and an oven door movably connected to the insert housing. The insert door comprises an interior surface and an exterior surface. The interior surface faces the interior cavity when the insert door is in a closed position. The exterior surface is opposite from the interior surface and faces away from the interior cavity when the insert door is in a closed position. A first portion of the interior surface extends further into the cavity when the insert door is in a closed position than a second portion of the interior surface.

A security door, including two non-metal boards, two metal boards disposed between the two non-metal boards, and being fixed one to the other, while forming at least one gap therebetween, and a plurality of pins, each extending between the two non-metal boards, through the two metal boards, for fixing the two non-metal boards one to the other.

A method of making a door involves providing a first door facing including a first raised region and a first panel recessed from the first raised region by a first dimension, and securing a first core insert having a thickness equal to the first dimension to the first raised region. A second door facing including a second raised region and a second panel recessed from the second raised region by a second dimension is provided. A second core insert having a thickness equal to the second dimension is secured to the second raised region. A central core component is secured to the first panel and the first core insert after the first core insert has been secured to the first raised region. The second panel and the second core insert are secured to the central core component after the second core insert has been secured to the second raised region.

A laminated door core for use in fire rated doors includes a center layer having a first side and an opposing second side, where the center layer comprises fire rated particleboard. The laminated door core also includes a first layer comprising calcium silicate adhered to the first side of the center layer, a second layer comprising calcium silicate adhered to the second side of the center layer, a first layer of high-density fiberboard adhered over the first layer of calcium silicate, and a second layer of high-density fiberboard adhered over the second layer of calcium silicate. A vertical stile may be positioned along each opposing longitudinal edge of the laminated door core, and a horizontal rail may be positioned along each of a top end and a bottom end of the laminated door core.

An illumination system is provided for an access door may include an elongated illumination housing configured to be coupled to at least one of an upstanding jamb and a corresponding jamb casing extending along the one side of the access door, an elongated light transmissive cover coupled to the illumination housing, an elongated light pipe received within the illumination housing, an illumination source housing operatively coupled to one end of the light pipe, an illumination source disposed within the illumination source housing and configured to produce and transmit visible light into the light pipe so as to be visible through the light transmissive cover, a source of electrical power, and a control unit configured to selectively apply electrical power from the source of electrical power to the illumination source to produce the visible light.

Disclosed are a fireproof cabinet body structure and a fireproof safety cabinet. The fireproof cabinet body structure comprises a cabinet body, the cabinet body comprises an inner panel, a gypsum board and a keel frame, and the inner panel and the gypsum board are fixedly mounted on two sides of the keel frame. The fireproof safety cabinet comprises a cabinet body and a cabinet door, the cabinet body is provided with an air inlet and an air outlet, ventilation fire-retardant valves are mounted at the air inlet and the air outlet, an inner side of the cabinet body is provided with an air supply opening corresponding to the air inlet and an air return opening corresponding to the air outlet, and the cabinet body is provided with electrostatic grounding bolts connected with the keel frame at the top part and/or side part of the cabinet body.

A bullet-resistant door includes a wooden frame forming a perimeter structure and protective layers that are collectively secured within the wooden frame. Such protective layers include: bullet-resistant panels that are made of a base material having embedded fibrous material and that are at least semi-rigid; and bullet-resistant sheets of a woven high-strength pliable fabric. In addition, a substantially hollow core that is at least ½ inch thick is provided between the protective layers

A door assembly for an electromagnetic shielded enclosure includes a metal door frame for defining a passageway into the enclosure and a door for selectively enclosing the passageway. The door includes a door leaf pivotally coupled to the frame. A set of radio frequency (RF) seals is connected to the exposed peripheral edge of a conductive plate in the door leaf. Each RF seal includes a resilient movable finger which overlies a U-shaped bracket mounted along the outer edge of the door leaf. A plurality of air cylinders is mounted within each bracket and is designed to urge the resilient finger of each RF seal into contact with the door frame.
