Sheridan County, KS Insulation Payback
Attic insulation payback for Sheridan County, KS
Sheridan County, Kansas 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 $1,651 a year in heating and cooling — a payback around 2.1 years. Hard to find a home improvement with a faster payback than this.
The breakdown behind the number
Of that, about $1,448/year comes from reduced heating and $203/year from reduced cooling load through the ceiling. Sheridan County beats 63% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 745 counties DOE places in zone 5, Sheridan County ranks 569th. Against Kansas's own average of $1,594/year, Sheridan County runs 4% above that.
Sheridan County's actual weather, not a national average
Sheridan County's climate figures — 5,417 heating and 1,262 cooling degree days a year — are read from HOXIE, KS US, 0.4 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Sheridan County sits at the 65th percentile nationally. DOE also classifies Sheridan County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
If the attic isn't bare
A shallower starting point changes the math: with R-11 already down, only the gap to R-49 needs filling, at roughly $2,280 for an estimated $241/year saved (~9.5-year payback). It is close - the payback only just fits a reasonable timeframe.
