What insulation workers, mechanical do

Mechanical insulation workers apply insulating materials to pipes, ductwork and other mechanical systems, such as industrial equipment, heat exchangers, tanks and vessels, so that noise is controlled and temperatures hold. They read blueprints and specifications to learn the job requirements, determine the amounts and types of insulation and the installation methods from factors such as location, surface shape and equipment use, and select the material, such as fiberglass, Styrofoam or cork, by its heat-retaining or heat-excluding characteristics. Insulation is measured and cut with tape measures, handsaws, knives and scissors, then fitted around obstructions and shaped, along with protective coverings, as needed. Surfaces and access holes are covered, sealed or finished with plastic covers, canvas strips, sealants, tape, cement or asphalt mastic, and sheet metal is screwed on around insulated pipes to protect them from weather and physical damage. Workers also remove and repair existing insulation. Floor, ceiling and wall insulation work (47-2131), which lines the structure itself, is classified separately.

Typical entry: Most workers in this occupation report a high school diploma or equivalent as their level of education, according to O*NET.

Also called: AC Insulation Installer (Air Conditioning Insulation Installer), Blanket Maker, Boiler Coverer, Commercial Insulator, Duct Insulator.

Median annual wage in each release, as published; a release without a published median has no point. The same numbers are in the table above.

BLS does not design OEWS as a time series: each release pools three years of samples, and occupational classifications, area definitions and estimation methods change between releases, so a difference between two releases is not a measure of change over time. The figures are shown as published, side by side, and nothing is computed from them. See how often OEWS is updated.
