Sheridan County, NE Insulation Payback
Sheridan County attic insulation, by the numbers
Sheridan County, Nebraska is zone 5 under DOE's climate map (Cold), which means winters that dominate the energy bill, with cooling a minor factor. 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 $1,983 a year in heating and cooling — a payback around 1.8 years. Topping up the attic pays for itself fast here.
Where the savings come from
Split it out and it's roughly $1,888 a year on the heating side, $96 on cooling. By estimated insulation savings, Sheridan County lands in the 81th percentile nationally. Zone 5 alone covers 745 counties in this dataset, and Sheridan County comes in 60th by savings. Nebraska averages $1,872/year across the counties tracked here; Sheridan County comes in 6% higher.
Sheridan County's actual weather, not a national average
Sheridan County's climate figures — 7,060 heating and 596 cooling degree days a year — are read from HAY SPRINGS 12 S, NE US, 16.6 miles away, NOAA's nearest 1991-2020 normals station. Combined heating and cooling load puts Sheridan County in the 81th percentile of this 3,162-county dataset. One local detail the R-value alone won't tell you: Sheridan County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
If the attic isn't bare
If Sheridan 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 $289/year — payback about 7.9 years. Worth doing on the numbers alone.

Where these figures come from
Sheridan 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.
