McCracken County, KY Insulation Payback
McCracken County attic insulation, by the numbers
McCracken 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 $1,320 a year in heating and cooling — a payback around 2.6 years. Topping up the attic pays for itself fast here.
Heating vs. cooling in McCracken County
Split it out and it's roughly $1,049 a year on the heating side, $270 on cooling. By estimated insulation savings, McCracken County lands in the 40th percentile nationally. Zone 4 alone covers 825 counties in this dataset, and McCracken County comes in 543rd by savings. Kentucky averages $1,385/year across the counties tracked here; McCracken County comes in 5% lower.
The climate data behind this
McCracken County's climate figures — 3,925 heating and 1,683 cooling degree days a year — are read from PADUCAH, KY US, 3.4 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, McCracken County sits at the 42th percentile nationally. One local detail the R-value alone won't tell you: McCracken County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
If the attic isn't bare
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $193/year saved — roughly 11.8 years to break even. Call this borderline rather than a clear win.
Getting it done in McCracken County
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 McCracken County job, not a quote. Expect at least a $600 minimum charge from most contractors.
Where these figures come from
McCracken 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.
