Provision is made for the thermal insulation of a non-planar portion of a body by fabricating a molded insulative piece which fits closely over the non-planar portion and may be secured thereto by way of an adhesive. A thermosetting foam which is adaptable to this use but is susceptible to damage by exposure to sunlight and to abrasive wear, is protected by an outer protective covering that may be integrally formed with a foam core section during the molding process.
