The body of a cabinet for storing temperature-sensitive articles such as magnetic discs and tapes is built by a process which involves the successive steps of (i) fabricating an internal skin; (ii) attaching so-called “phase-change”material to the skin; (iii) applying insulative polyurethane foam in-situ to the structure of step (ii); (iv) casting concrete or the like water-bearing material around the structure of step (iii); and (v) completing the outer finishing skin. Thus the conventional “double-box”structure is avoided. The door for the cabinet can be built by a similar sequence in which “phase-change”material, insulative form and water-bearing layers are applied successively to a pan forming the internal face of the door.

A method of constructing a fire-resistant enclosure for the protection of temperature-sensitive articles, which comprises constructing the body of said fire-resistant enclosure by the successive steps of providing an open box-like structure to constitute an internal skin of the body, applying to at least some of the external surface of said structure a layer of phase-change material, applying to the external surface of the assembly of said structure and phase-change material a layer of thermally-insulative material, and applying to the external surface of the assembly of said structure, phase-change material and thermally-insulative material a layer of water-bearing material, whereby the finished body comprises successive layers of said phase-change, thermally-insulative and water-bearing materials built upon said structure; constructing a door for said fire-resistant enclosure by the successive steps of providing a face structure to constitute an internal face of the door, applying to at least part of the external surface of said face structure a layer of phase-change material, applying to the external surface of the assembly of said face structure and phase-change material layer of thermally-insulative material, and applying to the external surface of the assembly of said face structure, phase-change material and thermally-insulative material a layer of water-bearing material, whereby the finished door comprises successive layers of said phase-change, thermally-insulative and water-bearing materials built upon said face structure; and uniting said body and door.
