Insulation Workers

What Insulation Workers Do

Insulation workers install and replace the materials used to insulate buildings or mechanical systems.

Work Environment

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, often in confined spaces.

How to Become an Insulation Worker

Floor, ceiling, and wall insulators typically learn their trade on the job. Mechanical insulators may complete an apprenticeship program after earning a high school diploma or equivalent.


The median annual wage for insulation workers, floor, ceiling, and wall was $40,380 in May 2019.

The median annual wage for insulation workers, mechanical was $48,690 in May 2019.

Job Outlook

Overall employment of insulation workers is projected to grow 3 percent from 2019 to 2029, about as fast as the average for all occupations. However, growth rates will vary by occupation.

Insulation workers, also called insulators, install and replace the materials used to insulate buildings or mechanical systems.


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

Insulators install and replace the material that saves energy and helps reduce noise in buildings and around vats, vessels, boilers, steam pipes, and water pipes. Insulators also install fire-stopping materials to prevent the spread of a fire and smoke throughout a building.

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 the health risks associated with handling asbestos, hazardous materials removal workers or specially trained insulators must remove asbestos before workers begin installing new insulation.

Insulators use common handtools, such as knives, trowels, and scissors. They also may use a variety of power tools, such as 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 plastic 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. To fill the space between wall studs and ceiling joists, workers either unroll, cut, fit, and staple batts of insulation or spray foam insulation.

Mechanical insulators apply insulation to equipment, pipes, or ductwork in many types of buildings.

Insulation workers, floor, ceiling, and wall held about 34,000 jobs in 2019. The largest employers of insulation workers, floor, ceiling, and wall were as follows:

Drywall and insulation contractors 67%
Building equipment contractors 11
Nonresidential building construction 2
Foundation, structure, and building exterior contractors 1
Self-employed workers 1

Insulation workers, mechanical held about 27,300 jobs in 2019. The largest employers of insulation workers, mechanical were as follows:

Building equipment contractors 62%
Drywall and insulation contractors 18
Other specialty trade contractors 4
Self-employed workers 1

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

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.

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.
