Wilcox County, AL Insulation Payback
Wilcox County attic insulation, by the numbers
Wilcox County sits in IECC climate zone 3 (Hot-Humid) — summers that stay hot and humid while winters barely register on the energy bill. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to R-49. Going from R-2 to the recommended R-49 costs roughly $2,820 installed for a typical attic (about 1,000 sq ft), and pays for itself in about 3 years at an estimated $950/year saved. Topping up the attic pays for itself fast here.
Heating vs. cooling in Wilcox County
Split it out and it's roughly $597 a year on the heating side, $353 on cooling. By estimated insulation savings, Wilcox County lands in the 13th percentile nationally. Zone 3 alone covers 690 counties in this dataset, and Wilcox County comes in 572nd by savings. Alabama averages $1,001/year across the counties tracked here; Wilcox County comes in 5% lower.
Wilcox County's actual weather, not a national average
NOAA's CAMDEN 3 NW, AL US station, 2.8 miles from Wilcox County, supplies the 2,252 HDD and 2,215 CDD this estimate runs on. Combined heating and cooling load puts Wilcox County in the 10th percentile of this 3,162-county dataset. One local detail the R-value alone won't tell you: Wilcox County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
If the attic isn't bare
A shallower starting point changes the math: with R-11 already down, only the gap to R-38 needs filling, at roughly $1,620 for an estimated $128/year saved (~12.7-year payback). Call this borderline rather than a clear win.
Getting it done in Wilcox County
Actual quotes will vary by attic access, existing debris, and whether the job needs air sealing first. Treat the $2,820 figure above as a planning number for Wilcox County, not a bid - contractors typically charge a $600 minimum regardless of job size.
Where these figures come from
Wilcox County's R-49 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-49 is the target here specifically.
