Heat and frost insulators

Insulators install insulation in both industrial and commercial mechanical systems, such as piping, boilers, duct work, storage tanks and equipment for the purpose of energy savings and burn protection, and to control system heat transfer and condensation.

What an insulator does

An insulation worker fabricates and installs insulating material on commercial and industrial process piping, piping supply, vents and drains for plumbing systems, as well as for heating, cooling, and ventilation systems, duct systems, reduction of fire hazards, and for protection from heat and cold in other mechanical hazards, and for protection from heat or cold in other mechanical piping systems. An insulator also alters and repairs insulating materials. The insulation worker uses a wide variety of hand tools and materials to perform the trade's various tasks.

Working conditions

The work for this craft is varied indeed. The asbestos/heat & frost insulator may work both indoors and out, on everything from storm-drain piping to air conditioning ductwork. Physical and health hazards include breathing of hazardous chemicals, but the use of protective safety equipment reduces these dangers.
