Neosho County, KS Insulation Payback
Attic insulation payback for Neosho County, KS
Neosho 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. For an attic around 1,000 square feet, closing the gap from R-2 to R-60 costs around $3,480 and saves an estimated $1,484 a year — payback in roughly 2.3 years. Hard to find a home improvement with a faster payback than this.
The breakdown behind the number
Of that, about $1,258/year comes from reduced heating and $226/year from reduced cooling load through the ceiling. Neosho 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, Neosho County ranks 201st. Against Kansas's own average of $1,594/year, Neosho County runs 7% below that.
Neosho County's actual weather, not a national average
Neosho County's climate figures — 4,704 heating and 1,407 cooling degree days a year — are read from CHANUTE 4E, KS US, 8.2 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Neosho County sits at the 54th percentile nationally. DOE also classifies Neosho 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
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $216/year saved — roughly 10.5 years to break even. It is close - the payback only just fits a reasonable timeframe.
