A sound damping door system having a door frame, a compression seal, a door slab, a bottom seal, and a concealed hinge assembly. The door frame includes male and female components adapted to engage each other in a rough door opening between first and second wall faces; and at least one isolation gasket adapted to be disposed between the male and female components. The compression seal is mounted to the door frame. The door slab includes an outer skin; an arched constrainment sheet inside the outer skin; a damping fill material inside the outer skin; and an acoustic insert inside the outer skin. The bottom seal is mounted to a bottom surface of the door slab such that the bottom seal is permitted to move relative to the door slab.

A door system and a method of making a door system including a metal door, a metal door frame for the metal door, and one or more door frame seals. The metal door and the metal door frame each include a steel outer surface with a first metal layer in contact with and that encapsulates or covers the steel outer surface, and a second metal layer in contact with and that encapsulates or covers the first metal layer. The first metal layer is different from the second metal layer. The first metal layer can be optional. The door frame seals are located on the metal door frame and provide conductivity between the metal door and the metal door frame. The door system preferably has an acceptable sound transmission class rating and RF shielding properties.

A high security two-way virtual cross-barrier observation and communication device has a mounting frame with a hardened core, a pair of digital displays, and a pair of cameras. The mounting frame may correspond to a typical interior door of a building or a relevant component of a vehicle, aircraft, or other relevant application. The hardened core is bullet-resistant and fire-resistant to protect occupants of a protected space from harm. The digital displays and cameras are positioned on opposing sides of the mounting frame, each camera transmitting a live video feed to the opposing display, creating the appearance of a window while protecting occupants. The digital displays may be used to display any desired information. An emergency protocol may be activated to communicate with emergency services. A plurality of laminate layers bond and encapsulate the displays and cameras to the hardened core, forming a rugged, self-contained unit with no moving parts.

An adjustable header having a first header piece and a second header piece, which are attachable to each other by a connector.
