As a Heat and Frost Insulator, you could think of yourself as giving houses and buildings the perfect coat to withstand every season. You will work with insulating material to prevent or reduce the flow of heat, cold, vapour, moisture, sound, or fire. These materials will be used on systems, equipment, walls, floors, and ceilings. Your job will also involve applying metal and plastic finishes. People like steady temperatures in their buildings, and you’re to thank for that.
