Hancock County, KY Insulation Payback
Hancock County, KY: what topping up your attic actually costs
DOE classifies Hancock 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. 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 $1,360 a year in heating and cooling — a payback around 2.6 years. That's about as fast as attic paybacks get.
Heating vs. cooling in Hancock County
The estimated savings split roughly $1,128/year heating, $233/year cooling. Out of every 100 US counties tracked here, Hancock County's savings potential beats roughly 43 of them. Within zone 4 specifically, it ranks 462nd of 825 counties by estimated savings. Kentucky averages $1,385/year across the counties tracked here; Hancock County comes in 2% lower.
The climate data behind this
Hancock County's climate figures — 4,217 heating and 1,450 cooling degree days a year — are read from CANNELTON, IN US, 6.1 miles away, NOAA's nearest 1991-2020 normals station. Combined heating and cooling load puts Hancock County in the 44th percentile of this 3,162-county dataset. Hancock County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
Already have some insulation?
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 $198/year saved (~11.5-year payback). This one is a genuine toss-up, not a clear yes.
Getting it done in Hancock County
Actual quotes will vary by attic access, existing debris, and whether the job needs air sealing first. Treat the $3,480 figure above as a planning number for Hancock County, not a bid - contractors typically charge a $600 minimum regardless of job size.
Nothing here is a guess
Every figure on this page traces to DOE/IECC climate zones and NOAA degree-day normals, documented in the methodology guide. The guide to what R-value actually means explains why R-60 is the target here specifically.
