Insulators maintain and apply thermal insulation to commercial and industrial structures and equipment.

What do Insulators do?

  • Read and interpret drawings and specifications to determine insulation requirements and select type of insulation.
  • Measure and cut insulating material to required dimensions using hand and power tools.
  • Apply and secure insulation using spraying, blowing, pasting, strapping, taping and other application and installation methods.
  • Fit insulation around obstructions and between studs and joists.
  • Install vapour barriers and remove asbestos or urea-formaldehyde insulation materials from buildings when required.

The ability to be focused and responsible is a vital part of insulators’ work and safety. The work often requires spending most of the day on their feet, bending, kneeling, working at heights, climbing (scaffolds, ladders) and lifting. Insulators must be able to use their body to brace large items and guide objects or materials into place. This requires them to have a good combination of motor co-ordination and manual and finger dexterity.

With experience, insulators act as mentors and trainers to apprentices in the trade. They could also move into positions such as maintenance, instructor, contractor, foreperson, superintendent or estimator.
