ABSTRACT:
A panel, which may form a wall or a door (12) of a fire resistant cabinet (10), consists of an outer casing (16, 26) and an inner panel (14, 24) spaced apart by zig-zag shaped bridging members (20, 22, 28). The inner panel is double-walled and contains a material which undergoes a phase change at a temperature below that at which the contents of the cabinet might suffer damage. The space between the outer casing and the inner panel contains a number of metal foils (32, 34) parallel to the outer casing which acts as radiant heat shields. The bridging members may be of ceramic material of low thermal conductivity, and may be slotted to increase their resistance to heat flow.
