Abstract
An insulating roll comprising: a metal conduit having an outer peripheral portion; a plurality of discs having outer peripheries and preferably fabricated from an inorganic material positioned axially on and around the metal conduit; a tubular shell having an inner surface about and spaced apart from said outer peripheries; metallic foils extending between each or a plurality of said discs from said outer peripheral portion to and beyond said outer peripheries to the inner surface of said tubular shell, said metallic foils being in interference or frictional contact with said inner surface. A novel method for attaching the tubular shell to the conduit to simplify removal and replacement thereof is also described.
