ABSTRACT:
Thermally insulative sleeves include a seamless, hollow, flexibly resilient inner tubular member woven of strand material including at least one metal wire strand, a separate, integral, at least essentially unbroken, metal surface member applied over the inner tubular member extending along and at least essentially completely surrounding the inner tubular member and a flexible outer cover also woven of strand material extending along and completely around the inner tubular member and metal surfaced member securing the metal surface member with the inner tubular member and offering some degree of protection. The inner tubular member may be knit from wire or from a combination of wire and glass fiber yarn, the latter providing some thermal insulative protection. The metal surfaced member may be foil or some other metal covered composite or laminate material sufficiently thin and pliable so as to be deformable by the inner member. The flexible outer mender is preferably wire strand continuously knitted around the other two members. Sleeves provide reflective and, with a glass fiber inner tubular member, insulative thermal protection.
