Insulators (Heat and Frost) cover exposed surfaces of pipes, steam generators, ducts, process vats and related equipment with a variety of insulating materials. They work on a wide variety of commercial and industrial sites, often in confined conditions with relatively dangerous substances. They often apply waterproofing products or vapour barriers over top of the insulating materials and, in some cases, they also remove old insulation material such as asbestos, ceramic fibres, lead, mould, and urea-formaldehyde from buildings.

Insulator (Heat and Frost) is a nationally designated trade under the Interprovincial Standards Red Seal program.
