Van Buren County, AR Insulation Payback
Van Buren County attic insulation, by the numbers
Van Buren County, Arkansas is zone 3 under DOE's climate map (Mixed-Humid), which means heating load in winter and cooling load in summer, both worth taking seriously here. An uninsulated attic there should be built 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 $1,338 a year in heating and cooling — a payback around 2.1 years. Topping up the attic pays for itself fast here.
Where the savings come from
Split it out and it's roughly $1,147 a year on the heating side, $191 on cooling. By estimated insulation savings, Van Buren County lands in the 41th percentile nationally. Zone 3 alone covers 690 counties in this dataset, and Van Buren County comes in 15th by savings. Arkansas averages $1,185/year across the counties tracked here; Van Buren County comes in 13% higher.
Where these numbers come from
NOAA's DENNARD 10 WSW, AR US station, 13.9 miles from Van Buren County, supplies the 4,323 HDD and 1,196 CDD this estimate runs on. Combined heating and cooling load puts Van Buren County in the 40th percentile of this 3,162-county dataset. One local detail the R-value alone won't tell you: Van Buren 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 $180/year saved — roughly 9 years to break even. Call this borderline rather than a clear win.
