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 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.

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.

A metal door and the method of making a metal door having powder coated, front and back skins, powder coated hinge and lock channels powder coated top and bottom channel and a core positioned within the door assembly.

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.
