Stafford County, KS Insulation Payback
Stafford County attic insulation, by the numbers
Stafford County sits in IECC climate zone 4 (Mixed-Humid) — real heating and real cooling seasons both, roughly balanced across the year. For a currently uninsulated attic, DOE and ENERGY STAR recommend building 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 $1,520 a year in heating and cooling — a payback around 2.3 years. Topping up the attic pays for itself fast here.
The breakdown behind the number
Split it out and it's roughly $1,260 a year on the heating side, $261 on cooling. By estimated insulation savings, Stafford County lands in the 54th percentile nationally. Zone 4 alone covers 825 counties in this dataset, and Stafford County comes in 143rd by savings. Kansas averages $1,594/year across the counties tracked here; Stafford County comes in 5% lower.
The climate data behind this
The heating and cooling degree days behind this estimate — 4,711 HDD and 1,624 CDD (base 65°F, 1991-2020 normals) — come from HUDSON, KS US, the nearest NOAA station with published normals, 5.8 miles from Stafford County's center. That combined heating-and-cooling load ranks Stafford County 1311th nationally by total degree days — the 59th percentile. One local detail the R-value alone won't tell you: Stafford County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
If the attic isn't bare
If Stafford 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 $222/year — payback about 10.3 years. Call this borderline rather than a clear win.
Next steps for a Stafford County attic
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 Stafford County job, not a quote. Expect at least a $600 minimum charge from most contractors.
Where these figures come from
Stafford County's R-60 target and its degree-day figures both come from named federal sources - see the methodology guide for exactly which ones. The guide to what R-value actually means explains why R-60 is the target here specifically.
