The enclosure is formed by a series of prefabricated walls or other panels (1,2) and spacing bars (3) dimensioned to fit within an existing space. The panels may be formed of moulded, extruded, folded or otherwise formed material, and are connected together by welding, gluing, bolting or riveting, or a combination of these or other methods. The space defined between the walls of the enclosure and those of the space which surrounds it may be filled with insulating material. The insulating material may also provide additional protection of the enclosure against unauthorised entry.
