Lightweight, glidable shielded components (e.g. doors) may be used in conjunction with accredited enclosures to provide electromagnetic, acoustic and CBR protection.

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.

The present sliding security door system includes a sliding security door extending between an upper track and a lower track. Separate motive and locking assemblies drive and secure the door, respectively. A control assembly in the system is capable of separately activating motive and locking effectors to allow for separate movement and locking/unlocking of the door. Because of this, the system is compact and capable of deployment in otherwise too-small spaces.

A roller shutter may include a rotatable drum; a shutter curtain including a series of three or more elongate slats pivotally interlocked in a longitudinal-edge-to-longitudinal-edge arrangement and arranged parallel to the rotatable drum, wherein a first and second longitudinal end portions of each elongate slat may be respectively aligned to form a first side border and a second side border, respectively, of the shutter curtain, wherein the first and second longitudinal end portions of each elongate slat may be respectively provided with at least one eyelet-structure which protrudes therefrom, whereby a first and second rows of eyelet-structures are formed along the first and second side borders; and at least a first cord and a second cord respectively strung loosely through all eyelet-structures of respective row of eyelet-structures, and each cord may be configured to confine all eyelet-structures of the respective row of eyelet-structures within a length of each cord.

A security panel system that is adapted to protect innocent bystanders from gunfire in the event of a shooting. The security panel system includes a main body having a first rail, a second rail, a panel, and a locking mechanism. The first rail and the second rail may each be mounted adjacent to a window and movably secure a panel therebetween. The panel is movable between an opened position and a closed position. The locking mechanism is configured to secure the panel in the closed position. It should be appreciated that, while the panel is in the closed position, the shooter may not be able to see or fire through the window due to use of the security panel system.

The application describes a frame assembly. The frame assembly comprises: first and second glass panels substantially parallel to each other; and an intermediate ballistic panel positioned between the first and second glass panels. A spacer element is positioned between the first and second glass panels and adapted to receive the intermediate ballistic panel. The spacer element comprises a recess adapted to receive the intermediate ballistic panel therein. The recess is larger than the intermediate ballistic panel in at least one dimension by a tolerance value to accommodate thermal expansion of the intermediate ballistic panel.
