Abstract: A modular SCIF includes a frame made from a plurality of prefabricated channels, and a plurality of prefabricated wall and ceiling panels that are attached to the frame. The frame, channels and panels are meet a set of standard dimensions. The SCIF fits within most offices and dwellings. The modular SCIF includes a prefabricated door and doorframe that are attached to the modular SCIF. The SCIF is attached directly to a concrete floor, the floor of a vehicle or to a track system. The panels include several layers, including a core layer of expanded metal and two layers of acoustic board. Additional layers include two layers of ABS plastic sheet, two layers of mass loaded vinyl sheet, two layers of galvanized steel sheet, and two layers of aluminum sheet. The additional layers may be used singly or collectively.
