Forensic Shielded Rooms

The forensic shielded room is specially designed to meet the requirements of evidence and examination rooms.


Global EMC’s Forensic shielded room is an electrically conductive volume that can be manufactured and designed in any size or shape. The principle is that radiated electromagnetic waves (magnetic/radio/microwave) hit the exterior of the room and flow around the outside in conducted micro-energies. The typical frequency range of a Faraday cage is 10 kHz to 18 GHz but can be extended to 1 kHz to 86 GHz if required. The forensic shielded room is specially designed to meet the requirements of evidence and examination rooms.

The shielded enclosure will be made in a bespoke size to fit the host building and maximise the usable space.

The shielding is an enclosure of all walls, ceiling and flooring using 2mm modular pan steel. This shielded enclosure gives superb performance. It is a modular assembly of individual steel fabrications that are produced from 2mm galvanized sheet steel. These are folded at the edges of each panel to form flanges which are bolted together. Double wire mesh gasket is placed between each flange to form a high performance electromagnetic seal. Rooms are designed with an air lock entry system where the opening of one door will not break the integrity of the shield. Indicator lights are provided to show when a door is opened and closed.
