ABSTRACT:
The protective enclosure is of the type composed of several panels of square or rectangular shape removably assembled to one another. Each panel is generally constituted by a sheet-metal plate whose edges are folded so as to form a stiffening frame bordering the inner surface of the panel and defining, on the side of said inner surface, a space adapted to receive a thermally and/or acoustically insulating material. Each said panel is equipped, on at least three of its edges, with means enabling it to form a rigid assembly with adjacent panels, and ensuring, simultaneously their tightening, their alignment and/or their squaring.
