Craighead County, AR Insulation Payback
Craighead County attic insulation, by the numbers
Craighead County sits in IECC climate zone 3 (Mixed-Humid) — a genuine mix of cold winters and humid summers, with neither one dominating the bill. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to R-49. For an attic around 1,000 square feet, closing the gap from R-2 to R-49 costs around $2,820 and saves an estimated $1,233 a year — payback in roughly 2.3 years. Topping up the attic pays for itself fast here.
Heating vs. cooling in Craighead County
Split it out and it's roughly $916 a year on the heating side, $318 on cooling. By estimated insulation savings, Craighead County lands in the 33th percentile nationally. Zone 3 alone covers 690 counties in this dataset, and Craighead County comes in 63rd by savings. Arkansas averages $1,185/year across the counties tracked here; Craighead County comes in 4% higher.
The climate data behind this
NOAA's JONESBORO MUNI AP, AR US station, 0.9 miles from Craighead County, supplies the 3,451 HDD and 1,994 CDD this estimate runs on. Combined heating and cooling load puts Craighead County in the 38th percentile of this 3,162-county dataset. One local detail the R-value alone won't tell you: Craighead 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 $166/year saved (~9.8-year payback). Call this borderline rather than a clear win.
Getting it done in Craighead 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 Craighead County, not a bid - contractors typically charge a $600 minimum regardless of job size.
Where these figures come from
Craighead 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.
