The new seamless lamination of a high-temperature fabric to a highly-reflective foil is the makeup of Thermo- Sleeve, which provides protection from radiant heat for hoses and wires. Thermo- Sleeve’s ultra light-weight construction provides more insulating than traditional bulky rubber-coated fiberglass. The aluminized sleeving reflects over 90% of radiant heat, and is fireproof and oil resistant.
