Pulaski County, AR Insulation Payback
Attic insulation payback for Pulaski County, AR
DOE classifies Pulaski County as climate zone 3, mixed-humid — heating load in winter and cooling load in summer, both worth taking seriously here. Its recommended attic R-value for bare joists is 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 $1,157 a year in heating and cooling — a payback around 2.4 years. Hard to find a home improvement with a faster payback than this.
Where the savings come from
Of that, about $840/year comes from reduced heating and $317/year from reduced cooling load through the ceiling. Pulaski County beats 28% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 690 counties DOE places in zone 3, Pulaski County ranks 153rd. Against Arkansas's own average of $1,185/year, Pulaski County runs 2% below that.
Where these numbers come from
NOAA's LITTLE ROCK AP ADAMS FLD, AR US station, 5.2 miles from Pulaski County, supplies the 3,165 HDD and 1,989 CDD this estimate runs on. By total degree days, Pulaski County sits at the 30th percentile nationally. DOE also classifies Pulaski County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
The smaller top-up scenario
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 $156/year saved (~10.4-year payback). It is close - the payback only just fits a reasonable timeframe.
Next steps for a Pulaski County attic
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 Pulaski County, not a bid - contractors typically charge a $600 minimum regardless of job size.
