Breathitt County, KY Insulation Payback
Breathitt County attic insulation, by the numbers
DOE classifies Breathitt 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. 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 $1,422 a year — payback in roughly 2.4 years. Topping up the attic pays for itself fast here.
Heating vs. cooling in Breathitt County
Split it out and it's roughly $1,271 a year on the heating side, $152 on cooling. By estimated insulation savings, Breathitt County lands in the 47th percentile nationally. Zone 4 alone covers 825 counties in this dataset, and Breathitt County comes in 338th by savings. Kentucky averages $1,385/year across the counties tracked here; Breathitt County comes in 3% higher.
Breathitt County's actual weather, not a national average
The heating and cooling degree days behind this estimate — 4,752 HDD and 944 CDD (base 65°F, 1991-2020 normals) — come from QUICKSAND, KY US, the nearest NOAA station with published normals, 2.1 miles from Breathitt County's center. That combined heating-and-cooling load ranks Breathitt County 1754th nationally by total degree days — the 45th percentile. One local detail the R-value alone won't tell you: Breathitt County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
The smaller top-up scenario
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $207/year saved — roughly 11 years to break even. Call this borderline rather than a clear win.
