Metcalfe County, KY Insulation Payback
Metcalfe County attic insulation, by the numbers
Metcalfe 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. 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 $1,356 a year — payback in roughly 2.6 years. Topping up the attic pays for itself fast here.
Heating vs. cooling in Metcalfe County
Split it out and it's roughly $1,140 a year on the heating side, $216 on cooling. By estimated insulation savings, Metcalfe County lands in the 43th percentile nationally. Zone 4 alone covers 825 counties in this dataset, and Metcalfe County comes in 474th by savings. Kentucky averages $1,385/year across the counties tracked here; Metcalfe County comes in 2% lower.
Where these numbers come from
NOAA's KNOB LICK 4S, KY US station, 4.2 miles from Metcalfe County, supplies the 4,263 HDD and 1,343 CDD this estimate runs on. Combined heating and cooling load puts Metcalfe County in the 42th percentile of this 3,162-county dataset. One local detail the R-value alone won't tell you: Metcalfe 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 $198/year saved — roughly 11.5 years to break even. Call this borderline rather than a clear win.
Getting it done in Metcalfe 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 Metcalfe County job, not a quote. Expect at least a $600 minimum charge from most contractors.

Metcalfe 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.
