What is a Heat & Frost Insulator?

Heat and Frost Insulators work with commercial and industrial insulation. They install insulation and soundproofing for heating, ventilation, steam generation, process piping and plumbing systems, remove hazardous waste, and firestopping.  Heat and Frost Insulators are responsible for installing the materials that control and maintain the temperature of buildings and mechanical equipment.  They work with adhesives, staples or tape to secure insulation to walls and structures, or use machines to blow insulation directly into spaces. A variety of machinery and power tools are constantly used.  They also remove asbestos and lead from old buildings prior to renovation or demolition.  Heat and Frost Insulators use vacuums and scrapers and have to work carefully to remove the asbestos during abatement.  Work is conducted in commercial buildings, refineries, ships, industrial plants and private residences in all kinds of indoor and outdoor climates.

The working conditions tend to be in and around dust. The minute particles from insulation materials, especially when blown, can irritate the eyes, skin and respiratory system. Removing cancer-causing asbestos insulation is a hazardous task. To protect from the dangers of asbestos and irritants, workers follow strict safety guidelines, take decontamination showers, keep work areas well ventilated and wear protective suits, masks and respirators.
