Kiowa County, KS Insulation Payback
Kiowa County, KS: what topping up your attic actually costs
DOE classifies Kiowa County as climate zone 4, mixed-humid — a genuine mix of cold winters and humid summers, with neither one dominating the bill. Its recommended attic R-value for bare joists is 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 $1,582 a year — payback in roughly 2.2 years. That's about as fast as attic paybacks get.
Where the savings come from
The estimated savings split roughly $1,359/year heating, $223/year cooling. Out of every 100 US counties tracked here, Kiowa County's savings potential beats roughly 58 of them. Within zone 4 specifically, it ranks 68th of 825 counties by estimated savings. Kansas averages $1,594/year across the counties tracked here; Kiowa County comes in 1% lower.
Where these numbers come from
The heating and cooling degree days behind this estimate — 5,081 HDD and 1,390 CDD (base 65°F, 1991-2020 normals) — come from GREENSBURG, KS US, the nearest NOAA station with published normals, 3 miles from Kiowa County's center. Combined heating and cooling load puts Kiowa County in the 61th percentile of this 3,162-county dataset. Kiowa County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
Already have some insulation?
If Kiowa County's attic already has 3-4 inches of old insulation (about R-11) rather than bare joists, the recommended target drops to R-49. That smaller top-up costs around $2,280 and saves an estimated $231/year — payback about 9.9 years. This one is a genuine toss-up, not a clear yes.

Nothing here is a guess
Every figure on this page traces to DOE/IECC climate zones and NOAA degree-day normals, documented in the methodology guide. The guide to what R-value actually means explains why R-60 is the target here specifically.
