A double isolated electrically shielded screen room in which all side, ceiling and floor panels thereof are provided with peripheral grooves. A tongue strip matingly engages the grooves in adjacent panels and clamping is completed with bolts. This construction minimizes the number of individual elements required for the screen room and facilitates assembly and disassembly. To reduce the possibility of the wood frame members being split, they may be partially cut through at the base of each groove. Alternatively, the frame members could be fully cut through, resulting in two individual pieces, permitting more freedom in putting the shielding on each panel.
