Woodson County, KS Insulation Payback
Woodson County attic insulation, by the numbers
DOE classifies Woodson County as climate zone 4, mixed-humid — heating load in winter and cooling load in summer, both worth taking seriously here. Its recommended attic R-value for bare joists is 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 2.3 years at an estimated $1,493/year saved. Topping up the attic pays for itself fast here.
The breakdown behind the number
Split it out and it's roughly $1,264 a year on the heating side, $230 on cooling. By estimated insulation savings, Woodson County lands in the 53th percentile nationally. Zone 4 alone covers 825 counties in this dataset, and Woodson County comes in 184th by savings. Kansas averages $1,594/year across the counties tracked here; Woodson County comes in 6% lower.
The climate data behind this
The heating and cooling degree days behind this estimate — 4,726 HDD and 1,430 CDD (base 65°F, 1991-2020 normals) — come from YATES CTR, KS US, the nearest NOAA station with published normals, 1.7 miles from Woodson County's center. That combined heating-and-cooling load ranks Woodson County 1421st nationally by total degree days — the 55th percentile. One local detail the R-value alone won't tell you: Woodson County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
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 $218/year saved (~10.5-year payback). Call this borderline rather than a clear win.
Next steps for a Woodson 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 Woodson County job, not a quote. Expect at least a $600 minimum charge from most contractors.
Where these figures come from
Woodson 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.
