An insulated structure, typically a drum, can initially have an outer uninsulated wall of heat conductive material. The outer wall, such as the outer cylindrical wall of a drum, may then be insulated with insulation supplied as panels. Each panel covers a part of the surface, e.g., extends part way around a portion of the circumference of a drum. Each panel connects, end-to-end, to at least one other insulation panel. Adjacent panels are advantageously joined end-to-end by adjustable joining means. Each panel has an outer metal sheet, such as of galvanized steel. This sheet has an inner layer of ceramic fiber insulation bonded to it. In addition to being attached to each other, panels may also be secured to the wall.
