Insulation workers install and replace the materials used to insulate buildings and mechanical systems. The US Bureau of Labor Statistics lists their duties as removing and disposing of old insulation, reviewing blueprints to work out what is needed, measuring and cutting insulation to fit walls and pipes, securing it with staples, tape or screws, spraying foam insulation with air compressors, and installing plastic barriers to keep out moisture. Floor, ceiling and wall insulators work in homes and other buildings; mechanical insulators insulate equipment, pipes and ductwork.
The short answer: AI is very unlikely to replace insulation workers. The ILO's 2025 index places insulation workers in its not exposed group, with a score of 0.13. The BLS projects employment to grow 3 percent from 2025 to 2035, about as fast as average, from 71,900 to 74,300 jobs, with about 4,800 openings a year. Projections are estimates, not guarantees.
How exposed insulation workers are
The International Labour Organization scores occupations' tasks from 0 (cannot be automated with generative AI) to 1 (could be done without a human operator), and groups them into gradients from 1 to 4, with 4 the most exposed; below them sit minimal exposure and not exposed (ILO Working Paper 140, 2025).
| Occupation (ISCO-08) | ILO category | Mean task score (0 to 1) |
|---|---|---|
| Insulation Workers | Not exposed | 0.13 |
This is physical work in attics, crawl spaces, scaffolding and plant rooms. The BLS says insulators spend the day standing, bending or kneeling in confined spaces, often at heights, which generative AI cannot do.
What the BLS projects
| Occupation | Projected change 2025 to 2035 | Openings a year |
|---|---|---|
| Insulation workers | Grow 3% | About 4,800 |
The BLS ties demand to the continuing need to make new and existing buildings and systems more energy efficient, and to the amount of new home building and retrofitting. Most openings come from replacing workers who retire or change jobs.
Where AI is helping
- Estimating materials and quotes from plans and measurements.
- Energy modeling that shows where a building loses heat, which tells crews where to work.
- Scheduling crews and ordering materials.
What stays with insulation workers
- Installation: cutting, fitting and securing material in awkward, irregular spaces.
- Safety: the BLS notes falls, cuts, irritating particles and, for mechanical insulators, burns from hot pipes.
- Removal: taking out old insulation, which for asbestos requires EPA accredited training.
- Judgment on site: spotting moisture, gaps and problems the plans do not show.
- Checking AI help: generated estimates and specifications can be wrong, which NIST calls confabulation (NIST AI 600-1). See checking AI output.
How the job is changing
Energy efficiency work keeps demand steady, and software helps with estimates and planning, while the installation itself stays hands on. The BLS says most floor, ceiling and wall insulators learn on the job, many mechanical insulators complete a 4 or 5 year apprenticeship after high school, and asbestos removal needs accredited training.

Pay and how to get in
The US Bureau of Labor Statistics puts the median annual pay for insulation workers at $51,330 in May 2025, against $50,980 for all workers. The BLS says the education needed to enter varies; its profile explains the routes in. See how this job compares in AI exposure by pay and AI exposure by education level.
Questions and answers
Will AI replace insulation workers?
Not on current projections. The BLS projects 3 percent growth from 2025 to 2035, with about 4,800 openings a year, and the ILO rates the job as not exposed.
How exposed are insulation workers to AI?
The ILO places insulation workers in its not exposed group, with a score of 0.13.
Why is demand for insulation workers growing?
The BLS points to the continuing need to make buildings and systems more energy efficient, and to new home building and retrofitting.
How do you become an insulation worker?
The BLS says most floor, ceiling and wall insulators learn on the job, while many mechanical insulators complete a 4 or 5 year apprenticeship.
