Ohio County, KY Insulation Payback
Ohio County attic insulation, by the numbers
Ohio County sits in IECC climate zone 4 (Mixed-Humid) — heating load in winter and cooling load in summer, both worth taking seriously here. 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 $1,382 a year in heating and cooling — a payback around 2.5 years. Topping up the attic pays for itself fast here.
The breakdown behind the number
Split it out and it's roughly $1,158 a year on the heating side, $224 on cooling. By estimated insulation savings, Ohio County lands in the 44th percentile nationally. Zone 4 alone covers 825 counties in this dataset, and Ohio County comes in 423rd by savings. Kentucky averages $1,385/year across the counties tracked here; Ohio County comes in 0% higher.
Where these numbers come from
Ohio County's climate figures — 4,330 heating and 1,393 cooling degree days a year — are read from BEAVER DAM, KY US, 4 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Ohio County sits at the 45th percentile nationally. One local detail the R-value alone won't tell you: Ohio 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 $202/year saved — roughly 11.3 years to break even. Call this borderline rather than a clear win.
Getting it done in Ohio County
Get more than one quote before committing. Attic access and any needed air sealing move the price around, and most contractors won't take a job below roughly $600 regardless of size - worth asking upfront given Ohio County's estimated $1,382/year on the line.
Where these figures come from
Ohio 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.
