An insulating roller cover is now disclosed that provides a highly desirable combination of features. The cover is free from asbestos and is therefore of more desirable construction for handling and use. For the roller cover, at least substantially ceramic fiber is highly compressed, providing a dense and refractory, elevated temperature resistant insulating cover. The cover may itself serve as a load bearing surface; or may provide a foundation or protective media for annular discs or 10 sleeve members made of various, load bearing materials. These load bearing materials may be unable to resist direct contact with the shaft due to thermal shock or the differences in their respective expansion and contraction rates. Where impregnant is utilized with the highly compressed fiber, such will often comprise a colloidal substituent.

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.
