Abstract: A ceiling tile system capable of mitigating radio-frequency and acoustic waves from passing therethrough including a set of conductive grid bars; and a set of ceiling tiles each having a layer of conductive material and a layer of acoustic insulation.

Abstract: A radio frequency (RF) and acoustic shielded door that has a door leaf with an acoustically insulated core. The perimeter of the door leaf is banded with a conductive contact channel, which is electro-mechanically bonded to a shielding media that is applied to the door face. A conductive angled contact is mechanically attached at a bottom of the door. An acoustic or radio frequency gasket seal assembly is attached to the door frame, and the gasket seal assembly is adjustable so that a complete seal can be formed around the head, jamb and sill of the door.

Abstract: An improved radiation resistant door seal which is comprised of a door member and frame member. The door member comprises a plurality of flange members and a conductive blade which extends lengthwise and is insertable within a channel formed within the frame member. The channel within the frame member further comprises side walls with bowed contact members on each side of the walls to engagingly capture the blade when inserted therein. A plurality of finger-like contact members is positioned within the door member such to provide enhanced shielding and electrical contact areas to thwart radiation penetration.
