Pike County, KY Insulation Payback
Pike County attic insulation, by the numbers
Pike County, Kentucky is zone 4 under DOE's climate map (Mixed-Humid), which means real heating and real cooling seasons both, roughly balanced across the year. 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 $1,298 a year — payback in roughly 2.7 years. Topping up the attic pays for itself fast here.
The breakdown behind the number
Split it out and it's roughly $1,074 a year on the heating side, $224 on cooling. By estimated insulation savings, Pike County lands in the 38th percentile nationally. Zone 4 alone covers 825 counties in this dataset, and Pike County comes in 587th by savings. Kentucky averages $1,385/year across the counties tracked here; Pike County comes in 6% lower.
The climate data behind this
NOAA's WILLIAMSON, WV US station, 14.9 miles from Pike County, supplies the 4,016 HDD and 1,397 CDD this estimate runs on. That combined heating-and-cooling load ranks Pike County 1975th nationally by total degree days — the 38th percentile. One local detail the R-value alone won't tell you: Pike County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
If the attic isn't bare
If Pike 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 $189/year — payback about 12 years. Call this borderline rather than a clear win.

Where these figures come from
Pike 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.
