HEAT & FROST INSULATORS & ALLIED WORKERS
International Association of Heat and Frost Insulators and Allied Workers
Heat and Frost Insulators apply thermal insulation to pipes, ducts, tanks, boilers, refrigeration equipment, and other surfaces requiring thermal control of temperatures. The responsibilities of these mechanics and apprentices also include the manufacture, fabrication, assembling, spraying, repairing, dismantling, reconditioning, corrosive control, testing, and maintenance of heat or frost insulation. Workers also handle insulation materials made of fiberglass, rubber, calcium silicate, and urethane. Asbestos workers also do removal of asbestos-containing materials.
