Abstract

Abstract This invention deals with casings useful for fabricating articles used in insulation methods and a blanket type thermal insulation formed from such articles that can be placed on substrates to prevent exaggerated changes in temperature of the substrate. The flexibility of the blanket allows for its use on a variety of configurations of substrates.
