Bayfield County, WI Insulation Payback
Attic insulation payback for Bayfield County, WI
Bayfield County, Wisconsin is zone 7 under DOE's climate map (Very Cold), which means severe, long winters where heating is nearly the whole story. An uninsulated attic there should be built up to R-60. Topping up a typical 1,000-square-foot attic from bare joists (R-2) to R-60 runs an estimated $3,480, and saves about $2,393 a year in heating and cooling — a payback around 1.5 years. Hard to find a home improvement with a faster payback than this.
The breakdown behind the number
Of that, about $2,352/year comes from reduced heating and $42/year from reduced cooling load through the ceiling. Bayfield County beats 96% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 120 counties DOE places in zone 7, Bayfield County ranks 96th. Against Wisconsin's own average of $2,200/year, Bayfield County runs 9% above that.
Bayfield County's actual weather, not a national average
NOAA's ASHLAND KENNEDY MEM AP, WI US station, 13.6 miles from Bayfield County, supplies the 8,796 HDD and 259 CDD this estimate runs on. That combined heating-and-cooling load ranks Bayfield County 147th nationally by total degree days — the 95th percentile.
If the attic isn't bare
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $349/year saved — roughly 6.5 years to break even. Topping up the attic pays for itself here.
