Ness County, KS Insulation Payback

Ness County, KS: what topping up your attic actually costs

Ness 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. Topping up a typical 1,000-square-foot attic from bare joists (R-2) to R-60 runs an estimated $3,480, and saves about $1,655 a year in heating and cooling — a payback around 2.1 years. That's about as fast as attic paybacks get.

Where the savings come from

The estimated savings split roughly $1,437/year heating, $218/year cooling. Out of every 100 US counties tracked here, Ness County's savings potential beats roughly 63 of them. Within zone 5 specifically, it ranks 563rd of 745 counties by estimated savings. Kansas averages $1,594/year across the counties tracked here; Ness County comes in 4% higher.

Ness County's actual weather, not a national average

The heating and cooling degree days behind this estimate — 5,375 HDD and 1,356 CDD (base 65°F, 1991-2020 normals) — come from NESS CITY, KS US, the nearest NOAA station with published normals, 2 miles from Ness County's center. By total degree days, Ness County sits at the 66th percentile nationally. Ness County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.

If the attic isn't bare

Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $241/year saved — roughly 9.4 years to break even. This one is a genuine toss-up, not a clear yes.

Getting it done in Ness County

Real bids depend on how easy the attic is to reach and whether old insulation needs removing first, so treat $3,480 as a starting estimate for a Ness County job, not a quote. Expect at least a $600 minimum charge from most contractors.

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.
