How much do insulation workers earn on prevailing wage jobs in Idaho?
Every row below is one wage determination line: a insulation worker classification, in one county, for one construction type, under one funding source. The rate that applies to your project is the row whose county, construction type and funding source all match it — a Highway rate does not apply to a Building project in the same county, and a state determination does not substitute for a federal one.
What does the insulation worker classification cover?
Insulation workers apply thermal and acoustic insulation. Mechanical insulation — pipe, duct and vessel lagging — is usually a distinct and higher-rated classification than batt and blown building insulation, and asbestos abatement is separate again.
Work typically covered
- Pipe and duct insulation
- Vessel and equipment lagging
- Batt and blown building insulation
- Firestopping
- Jacketing and cladding
Also listed as

Insulation Worker prevailing wage questions
What is the prevailing wage for a insulation worker in Idaho?
Across the 23 federal-funded determination records WageFinder lists for insulation workers in Idaho, total prevailing wage runs from $21.93 to $21.96 per hour, median $21.93. There is no single statewide figure: each county's determination sets its own rate, and the same county can carry different rates for Building, Highway, Heavy and Residential work.
Does the insulation worker rate include benefits?
The total prevailing wage shown is the base hourly rate plus the fringe benefit rate. Of the 23 Idaho records on this page, 23 list a fringe amount separately, with a median of $1.80 per hour — roughly 8% of the median total. The rest list no separate fringe, meaning the base rate is the whole obligation. Fringe can be paid as bona fide benefit plan contributions, as cash added to the paycheck, or as a mix of both.
