Osborne County, KS Insulation Payback
Attic insulation payback for Osborne County, KS
Osborne County, Kansas is zone 5 under DOE's climate map (Cold), which means a real winter that drives most of the annual energy bill here. An uninsulated attic there should be built 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 years at an estimated $1,707/year saved.
Hard to find a home improvement with a faster payback than this.
The breakdown behind the number
Of that, about $1,493/year comes from reduced heating and $214/year from reduced cooling load through the ceiling. Osborne County beats 66% of the counties in this 3,171-county dataset on estimated insulation savings. Among the 754 counties DOE places in zone 5, Osborne County ranks 482nd. Against Kansas's own average of $1,594/year, Osborne County runs 7% above that.
Osborne County's actual weather, not a national average
Osborne County's climate figures — 5,584 heating and 1,334 cooling degree days a year — are read from Alton 1 W, KS US, 14 miles away, NOAA's nearest 1991-2020 normals station. Combined heating and cooling load puts Osborne County in the 70th percentile of this 3,171-county dataset. DOE also classifies Osborne 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 $249/year saved (~9.2-year payback). It is close - the payback only just fits a reasonable timeframe.
Getting it done in Osborne County
Get quotes from at least two local contractors 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 checking upfront given Osborne County's estimated $1,707/year on the line.
