Green Bay labor market for attic insulation

Insulation workers, floor, ceiling and wall (47-2131), 80% of the weighting: a median of $23.71 an hour, in line with the US median of $23.62.

Construction laborers (47-2061), 20% of the weighting: a median of $26.39 an hour, 16% above the US median of $22.66. The middle half of them earn between $22.53 and $31.63 an hour.
