Monroe County, AR Insulation Payback

Monroe County attic insulation, by the numbers

Monroe County sits in IECC climate zone 3 (Mixed-Humid) — real heating and real cooling seasons both, roughly balanced across the year. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to R-49. Topping up a typical 1,000-square-foot attic from bare joists (R-2) to R-49 runs an estimated $2,820, and saves about $1,175 a year in heating and cooling — a payback around 2.4 years. Topping up the attic pays for itself fast here.

Where the savings come from

Split it out and it's roughly $857 a year on the heating side, $318 on cooling. By estimated insulation savings, Monroe County lands in the 29th percentile nationally. Zone 3 alone covers 690 counties in this dataset, and Monroe County comes in 126th by savings. Arkansas averages $1,185/year across the counties tracked here; Monroe County comes in 1% lower.

The climate data behind this

NOAA's CLARENDON, AR US station, 5.8 miles from Monroe County, supplies the 3,230 HDD and 1,993 CDD this estimate runs on. By total degree days, Monroe County sits at the 32th percentile nationally. One local detail the R-value alone won't tell you: Monroe County sits in moisture regime A (humid), which can affect the vapor-barrier choice.

Already have some insulation?

Already have a few inches up there? Topping R-11 up to R-38 runs about $1,620 for about $158/year saved — roughly 10.2 years to break even. Call this borderline rather than a clear win.

Where these figures come from

Monroe 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.
