Abstract: A self-contained room capable of shielding the interior environment from magnetic and radio frequency interferences, as well as other wave and vibrational disturbances, comprised of an outer enclosure and an inner enclosure, raised above an existing floor by a fiberglass dowel system. The walls of both enclosures are made of mumetel sheets, pressure sealed to protect against ambient and man-made interferences, with an underlying aluminum structural frame. All seams and penetrations are shielded against wave interferences of natural or man-made origin.
