What Insulation Workers Do[About this section] [To Top]
Insulation workers, also called insulators, install and replace the materials used to insulate buildings and their mechanical systems.
Duties of Insulation Workers
Insulators typically do the following:
- Remove and dispose of old insulation
- Review blueprints and specifications to determine the amount and type of insulation needed
- Measure and cut insulation to fit into walls and around pipes
- Secure insulation with staples, tape, or screws
- Use air compressors to spray foam insulation
- Install plastic barriers to protect insulation from moisture
Insulated buildings save energy by keeping heat in during the winter and out in the summer. Insulated vats, vessels, boilers, steam pipes, and water pipes prevent the loss of heat or cold and prevent burns. In addition, insulation helps reduce noise that passes through walls and ceilings.
Insulators often must remove old insulation when renovating buildings. In the past, asbestos—now known to cause cancer—was used extensively to insulate walls, ceilings, pipes, and industrial equipment. Because of this danger, hazardous materials removal workers or specially trained insulators are required to remove asbestos before workers can begin installation.
Insulators use common hand tools, such as knives and scissors. They also may use a variety of power tools, such as power saws to cut insulating materials, welders to secure clamps, staple guns to fasten insulation to walls, and air compressors to spray insulation.
Insulators sometimes wrap a cover of aluminum, sheet metal, or vapor barrier (plastic sheeting) over the insulation. Doing so protects the insulation from contact damage and keeps moisture out.
Floor, ceiling, and wall insulators install insulation in attics, under floors, and behind walls in homes and other buildings. Most of these workers unroll, cut, fit, and staple batts of fiberglass insulation between wall studs and ceiling joists. Alternatively, some workers spray foam insulation with a compressor hose into the space being filled.
Mechanical insulators apply insulation to equipment, pipes, or ductwork in businesses, factories, and many other types of buildings. When insulating a steam pipe, for example, they consider the diameter, thickness, and temperature of the pipe in determining the type of insulation to be used.
Work Environment for Insulation Workers[About this section] [To Top]
Floor, ceiling, and wall insulation workers, hold about 33,700 jobs. The largest employers of floor, ceiling, and wall insulation workers are as follows:
| Drywall and insulation contractors | 62% |
| Building equipment contractors | 13% |
| Self-employed workers | 8% |
| Nonresidential building construction | 2% |
| Foundation, structure, and building exterior contractors | 1% |
Mechanical insulation workers hold about 31,200 jobs. The largest employers of mechanical insulation workers are as follows:
| Building equipment contractors | 61% |
| Drywall and insulation contractors | 18% |
| Self-employed workers | 8% |
| Other specialty trade contractors | 0% |
Insulators generally work indoors. Mechanical insulators work both indoors and outdoors, sometimes in extreme temperatures. They spend most of their workday standing, bending, or kneeling in confined spaces. Insulators may work at great heights on scaffolding, work platforms, or ladders.
Injuries and Illnesses for Insulation Workers
Common hazards for insulation workers include falls from ladders and cuts from knives. In addition, small particles from insulation materials can irritate the eyes, skin, and lungs. To protect themselves, insulators must keep the work area well-ventilated and follow product and employer safety recommendations. They also may wear personal protective equipment (PPE), including suits, masks, and respirators, to protect against hazardous fumes or materials.
Mechanical insulators may get burns from insulating pipes that are in service.
Insulation Worker Work Schedules
Most insulators work full time, and more than 40 hours a week may be required to meet construction deadlines. Those who insulate outdoors may not be able to work in bad weather, such as during a storm or in extreme heat or cold.
How to Become an Insulation Worker[About this section] [To Top]
Get the education you need: Find schools for Insulation Workers near you!
Most floor, ceiling, and wall insulators learn their trade on the job. Many mechanical insulators complete an apprenticeship program after earning a high school diploma or equivalent.
Education for Insulation Workers
There are no specific education requirements for floor, ceiling, and wall insulators. Mechanical insulators should have a high school diploma. High school courses in basic math, woodworking, mechanical drawing, algebra, and general science are considered helpful for all types of insulators.
Insulation Worker Training
Most floor, ceiling, and wall insulators learn their trade on the job. New workers are provided basic instruction on installation as well as mandatory Occupational Safety and Health Administration (OSHA) safety training on handling insulation and asbestos. Insulators who install blown or sprayed insulation will work alongside more experienced workers to learn how to operate equipment before being tasked with leading a spray installation job.
Many mechanical insulators learn their trade through a 4-year apprenticeship. Some apprenticeships may last up to 5 years. For each year of a typical program, apprentices complete at least 144 hours of technical instruction and 2,000 hours of paid on-the-job training.
Unions and individual contractors offer apprenticeship programs. Although most insulators start out by entering apprenticeships directly, others begin by working as helpers. The International Association of Heat and Frost Insulators and Allied Workers provides contact information on local union chapters.
Licenses, Certifications, and Registrations for Insulation Workers
Insulation workers who remove and handle asbestos must be trained through a program accredited by the U.S. Environmental Protection Agency.
The National Insulation Association offers a certification for mechanical insulators who conduct energy appraisals to determine if and how insulation can benefit industrial customers.
Important Qualities for Insulation Workers
Dexterity. Insulators often reach above their heads to install insulation, sometimes in confined spaces, where maneuvering can be difficult.
Math skills. Mechanical insulators need to measure the size of the equipment or pipe they are insulating to determine the amount and dimensions of insulation needed.
Mechanical skills. Insulators use a variety of hand and power tools to install insulation. Those who apply foam insulation, for example, must be able to operate and maintain an air compressor and sprayer to spread the foam onto walls or across attics.
Physical stamina. Insulators spend much of the workday standing, kneeling, and bending in uncomfortable positions.

Job Outlook for Insulation Workers[About this section] [To Top]
Overall employment of insulation workers is projected to grow 3 percent over the next ten years, slower than the average for all occupations.
Despite limited employment growth, about 6,000 openings for insulation workers are projected each year, on average, over the decade. Most of those openings are expected to result from the need to replace workers who transfer to different occupations or exit the labor force, such as to retire.
Employment of Insulation Workers
The continuing need to make new and existing buildings and systems more energy efficient will drive the demand for mechanical insulation workers.
The amount of new home building and retrofitting of existing insulation will continue to be linked to the employment of floor, ceiling, and wall insulation workers over the projections decade.
