Insulator (Heat and Frost)

Duties

Insulators (heat and frost) apply, remove and repair thermal and acoustical insulation (e.g. calcium silicate, glass foam, mineral wool, styrofoam, fibreglass) on all types of industrial equipment (e.g. duct piping, heat exchangers, tanks, vessels).

In general, insulators (heat and frost):

  • read and interpret drawings and specifications to determine insulation requirements
  • select the amount and type of insulation to be installed as well as a method of securing the insulation (e.g., spraying, pinwelding, wiring, pasting, strapping, taping) according to the type and shape of surface, whether or not the equipment is cold or hot, inside or outside, and what the equipment is going to be used for
  • measure and cut insulating material and coverings to the required shape and dimension
  • fit insulation around obstructions or shape insulation materials and protective coverings
  • install vapour barriers and finish insulated surfaces by applying metal cladding, canvas, plastic sheeting or cement
  • remove or seal off old asbestos insulation.

For more information regarding tasks and activities, please review the Trade Regulation.

Employment and Advancement

Insulators (heat and frost) are employed by construction companies, insulation contractors and industrial plant. This occupation is subject to business cycle swings which can lead to periodic high levels of unemployment.

Journeyperson wage rates are competitive with other trades in similar industry sectors, but generally range from $30 to $42 an hour, plus benefits.

Insulators may advance to supervisory positions such as foreman, general foreman or superintendent. They may also advance to estimator positions. Estimators review blueprints for proposed work, determine how much material will be needed and how long the work will take.
