Ashland County, WI Insulation Payback
Ashland County attic insulation, by the numbers
Ashland County sits in IECC climate zone 7 (Very Cold) — a climate where the heating season stretches across most of the year. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to R-60. For an attic around 1,000 square feet, closing the gap from R-2 to R-60 costs around $3,480 and saves an estimated $2,421 a year — payback in roughly 1.4 years. Topping up the attic pays for itself fast here.
Where the savings come from
Split it out and it's roughly $2,375 a year on the heating side, $47 on cooling. By estimated insulation savings, Ashland County lands in the 96th percentile nationally. Zone 7 alone covers 120 counties in this dataset, and Ashland County comes in 86th by savings. Wisconsin averages $2,200/year across the counties tracked here; Ashland County comes in 10% higher.
Ashland County's actual weather, not a national average
Ashland County's climate figures — 8,882 heating and 290 cooling degree days a year — are read from ASHLAND 3S, WI US, 11.2 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Ashland County sits at the 96th percentile nationally.
Already have some insulation?
If Ashland County's attic already has 3-4 inches of old insulation (about R-11) rather than bare joists, the recommended target drops to R-49. That smaller top-up costs around $2,280 and saves an estimated $353/year — payback about 6.5 years. Worth doing on the numbers alone.
