You must complete four years of Apprenticeship Training to become a Red Seal Certified Journeyperson Insulator. In addition to the practical training that apprentices receive on the job, you also take five weeks of theory and schooling for first and second year, and four weeks of theory and schooling for third and fourth year.

You can continue your apprenticeship with any Heat & Frost Insulation company in Canada, and most in North America. You don’t need to complete the apprenticeship within four years. You can take time away, and return to the program as long as you have the required hours worked.
