Lane County, KS Insulation Payback
Attic insulation payback for Lane County, KS
Lane County, Kansas is zone 5 under DOE's climate map (Cold), which means cold enough that heating, not cooling, is what decides the bill. An uninsulated attic there should be built 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 $1,637 a year — payback in roughly 2.1 years. Hard to find a home improvement with a faster payback than this.
Heating vs. cooling in Lane County
Of that, about $1,424/year comes from reduced heating and $214/year from reduced cooling load through the ceiling. Lane County beats 62% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 745 counties DOE places in zone 5, Lane County ranks 594th. Against Kansas's own average of $1,594/year, Lane County runs 3% above that.
The climate data behind this
Lane County's climate figures — 5,325 heating and 1,330 cooling degree days a year — are read from HEALY, KS US, 11.7 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Lane County sits at the 65th percentile nationally. DOE also classifies Lane County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
Already have some insulation?
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $239/year saved — roughly 9.5 years to break even. It is close - the payback only just fits a reasonable timeframe.
