Butler County, KS Insulation Payback
Attic insulation payback for Butler County, KS
Butler County, Kansas is zone 4 under DOE's climate map (Mixed-Humid), which means a genuine mix of cold winters and humid summers, with neither one dominating the bill. 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 $1,488 a year in heating and cooling — a payback around 2.3 years. Hard to find a home improvement with a faster payback than this.
The breakdown behind the number
Of that, about $1,235/year comes from reduced heating and $253/year from reduced cooling load through the ceiling. Butler County beats 52% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 825 counties DOE places in zone 4, Butler County ranks 194th. Against Kansas's own average of $1,594/year, Butler County runs 7% below that.
Where these numbers come from
Butler County's climate figures — 4,620 heating and 1,574 cooling degree days a year — are read from EL DORADO, KS US, 3.1 miles away, NOAA's nearest 1991-2020 normals station. Combined heating and cooling load puts Butler County in the 56th percentile of this 3,162-county dataset. DOE also classifies Butler County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
Already have some insulation?
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 $217/year saved (~10.5-year payback). It is close - the payback only just fits a reasonable timeframe.
