Insulators perform some or all of the following duties:

  • read and interpret drawings and specifications to determine insulation requirements and select type of insulation required
  • 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
  • apply waterproofing cement over insulating materials to finish surfaces
  • remove asbestos or urea-formaldehyde insulation from buildings when required

Work environment

Insulators typically work a standard 40-hour workweek, however, they may also be required to work longer hours to complete projects on time. Insulating work in the Construction industry is often project based and workers may experience gaps in employment between projects. For the same reason, insulators sometimes travel to where the work is.

Insulators generally work indoors. They often work at heights and in confined spaces. The work environment can be dusty and workers can be exposed to particles of insulation material that can be irritating to the eyes, skin and respiratory system. Workers strictly conform to health and safety procedures to protect themselves from exposure to airborne particles and skin irritants.

Heat and frost insulators who work on large industrial, institutional and commercial construction projects work both indoors and outdoors in all regions of Canada.

Job requirements

Education, training & qualifications

No formal minimum education is required for most insulation contractors in B.C., however, they must have basic reading/writing skills and be able to perform paperwork related duties. While trade certification is not required to be an insulator in B.C., it will likely increase job opportunities.

Requirements for trade certification include:

  • completion of an apprenticeship program (or a combination of several years of work experience and some college or industry courses in insulation)

In addition, many insulators are expected to operate and maintain diesel powered blowing machines and must have a valid driver’s license.

The Industry Training Authority offers a four-year apprenticeship program for insulators specializing in the area of heat and frost insulation. Apprenticeship programs:

  • may begin in secondary school, through entry-level training programs at colleges and technical institutes, or through direct entry to the workplace
  • involve a combination of work experience and technical training
  • require workers to find a sponsor employer who is willing to participate in the program

Interprovincial Standards Red Seal certification is available to insulators through the Industry Training Authority. This allows holders to work in any province or territory. Once individuals pass the final examination of their accredited training program, they will achieve certification and will automatically receive Red Seal qualification.

Insulators with 8,880 hours of documented, directly related work experience can challenge the Interprovincial Red Seal examination. For more information please see the Industry Training Authority website at

As of July 1, 2017 when the Canadian Free Trade Agreement (CFTA) came into force, you will not need significant additional training, experience, testing or assessment if your qualifications or certificates are recognized by a Canadian regulatory authority. This applies whether you were trained in Canada or internationally.

Insights from industry

Of the opportunities that arise in the coming years, approximately one-half will come from retirements.

Government funding for capital projects has been an important source of construction employment. Major investments are planned and are underway in B.C.'s transportation infrastructure, including ports and airports.

Industry sources report that demand for workers may be higher for those who work mainly in spray foam.

At present, experienced insulators are in relatively short supply, and in general the experienced workforce is approaching retirement age; however, training is provided to those requiring experience.

Career paths and resources

Career paths

New hires often begin by working with the batting and sprayed two part polyurethane foam as well as working on a blowing truck. With experience and additional training, insulators can become insulation estimators.

Progression to supervisory positions, such as crew leader, site foreman, general foreman or project manager is also possible with experience.

Some experienced insulators may also choose to become independent contractors or company owners.
