Apply, remove, and repair insulation on pipes, ductwork, and mechanical systems — precision material work that keeps power plants, refineries, and commercial buildings energy-efficient and safe.
Heat & frost insulators apply, remove, and repair insulation on pipes, ductwork, boilers, tanks, and other mechanical systems to control temperature, cut energy loss, and reduce noise. They measure and cut fiberglass, calcium silicate, foam, and other insulating material to fit around obstructions, then cover and seal finished surfaces with canvas, mastic, tape, or sheet metal jacketing to protect against weather and physical damage. On industrial and commercial sites, insulators are also trained and certified to handle removal of asbestos-containing material under strict safety protocols.
- ✓ Measure and cut insulation for covering surfaces, using tape measures, handsaws, knives, or scissors.
- ✓ Apply, remove, and repair insulation on industrial equipment, pipes, ductwork, or mechanical systems to control noise and maintain temperature.
- ✓ Select appropriate insulation — fiberglass, Styrofoam, cork, or other material — based on heat-retaining or excluding characteristics.
- ✓ Fit insulation around obstructions, shaping insulating materials and protective coverings as required.
- ✓ Determine the amount and type of insulation needed, and method of installation, based on location, surface shape, and equipment use.
- ✓ Cover, seal, or finish insulated surfaces with plastic covers, canvas strips, sealants, tape, cement, or asphalt mastic.
- ✓ Install sheet metal around insulated pipes to protect the insulation from weather or physical damage.
- ✓ Read blueprints and specifications to determine job requirements.
- ✓ Prepare surfaces for insulation application by brushing on adhesives or cement, or attaching metal pins.

Prevailing wage is set per county and local, so actual pay varies by employer and location. Source: ACT Ohio county prevailing-wage schedules.
Typical Entry Requirement — A high school diploma or GED is the standard minimum; no four-year degree is required.
Apprenticeship Path — Most insulators enter the trade through a 4-year apprenticeship sponsored by the International Association of Heat & Frost Insulators and Allied Workers, combining paid on-the-job training with in-class instruction.
Core Coursework — Insulation materials and systems, blueprint reading, applied mathematics, and asbestos-abatement safety procedures are emphasized throughout the apprenticeship.
Certifications — Many insulators pursue OSHA safety credentials and asbestos-handling certifications to qualify for industrial and hazmat work.
