Barton County, KS Insulation Payback
Attic insulation payback for Barton County, KS
Barton County sits in IECC climate zone 4 (Mixed-Humid) — heating load in winter and cooling load in summer, both worth taking seriously here. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to R-60. Going from R-2 to the recommended R-60 costs roughly $3,480 installed for a typical attic (about 1,000 sq ft), and pays for itself in about 2.2 years at an estimated $1,599/year saved. Hard to find a home improvement with a faster payback than this.
Where the savings come from
Of that, about $1,387/year comes from reduced heating and $212/year from reduced cooling load through the ceiling. Barton County beats 60% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 825 counties DOE places in zone 4, Barton County ranks 51st. Against Kansas's own average of $1,594/year, Barton County runs 0% above that.
Where these numbers come from
Barton County's climate figures — 5,188 heating and 1,320 cooling degree days a year — are read from GREAT BEND 3W, KS US, 8.9 miles away, NOAA's nearest 1991-2020 normals station. That combined heating-and-cooling load ranks Barton County 1209th nationally by total degree days — the 62th percentile. DOE also classifies Barton County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
The smaller top-up scenario
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 $233/year saved (~9.8-year payback). It is close - the payback only just fits a reasonable timeframe.

Get more than one quote before committing. Attic access and any needed air sealing move the price around, and most contractors won't take a job below roughly $600 regardless of size - worth asking upfront given Barton County's estimated $1,599/year on the line.
