Taylor County, WI Insulation Payback
Taylor County attic insulation, by the numbers
DOE classifies Taylor County as climate zone 7, very cold — severe, long winters where heating is nearly the whole story. Its recommended attic R-value for bare joists is 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 $2,397 a year — payback in roughly 1.5 years. Topping up the attic pays for itself fast here.
Where the savings come from
Split it out and it's roughly $2,343 a year on the heating side, $54 on cooling. By estimated insulation savings, Taylor County lands in the 96th percentile nationally. Zone 7 alone covers 120 counties in this dataset, and Taylor County comes in 93rd by savings. Wisconsin averages $2,200/year across the counties tracked here; Taylor County comes in 9% higher.
The climate data behind this
NOAA's MEDFORD, WI US station, 9.6 miles from Taylor County, supplies the 8,763 HDD and 334 CDD this estimate runs on. Combined heating and cooling load puts Taylor County in the 96th percentile of this 3,162-county dataset.
Already have some insulation?
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $350/year saved — roughly 6.5 years to break even. Worth doing on the numbers alone.

Taylor County's R-60 target and its degree-day figures both come from named federal sources - see the methodology guide for exactly which ones. The guide to what R-value actually means explains why R-60 is the target here specifically.
