Learn to apply, remove and repair thermal and acoustical insulation on all types of commercial and industrial equipment - such as calcium silicate, glass foam, mineral wool, styrofoam and fibreglass - on all types of commercial and industrial equipment.

If you are comfortable working at heights and like precise tasks, then you'll enjoy a career as an insulator.

Throughout your career, you will read and interpret drawings and specifications to determine insulation requirements, select the amount and type of insulation to be installed as well as the method of securing the insulation according to the type and shape of the surface, whether or not the equipment is cold or hot, inside or outside and what the equipment is going to be used for.

You'll also measure, cut and fit insulating material and coverings to the required shape and dimension, install vapour barriers and finish insulated surfaces by applying metal cladding, canvas, plastic sheeting or cement and remove or seal old asbestos insulation.

This is a non-compulsory trade – individuals can work in the trade without certification if the employer deems the individual to have the skills of a journeyperson. However, individuals who are working in the trade and learning the trade must become a registered apprentice.

Is this the right fit for me?

Students who have the following characteristics see greater success in the trade:

  • manual dexterity
  • the strength, stamina and ability to use proper lifting techniques to lift items weighing up to 25 kilograms
  • the ability to work at various elevations, in confined spaces and in hot and cold environments
  • the ability to work alone in a team environment
  • a commitment to safe work habits


Upon successfully completing the required working hours and technical training periods, graduates will be awarded journeyperson status by Alberta’s Apprenticeship and Industry Training.

This is a Red Seal Endorsed trade – a recognizable standard that allows tradespeople to work across Canada.

Career opportunities

Start your career by finding an employer who is willing to indenture you as an apprentice. As an insulator, you will likely be employed by construction companies, insulation contractors and industrial plants. You will work indoors and outdoors all year round in both commercial and industrial settings.

After becoming a journeyperson, you may advance to supervisory positions or take on new apprentices. Insulators may advance to positions such as foreman, general foreman, site superintendent or other management opportunities. 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. Some journeypersons go on to run their own businesses – we can help you build your business with our Blue Seal business certificate.
