Pemiscot County, MO Insulation Payback
Attic insulation payback for Pemiscot County, MO
DOE classifies Pemiscot County as climate zone 4, mixed-humid — a genuine mix of cold winters and humid summers, with neither one dominating the bill. Its recommended attic R-value for bare joists is R-60. Topping up a typical 1,000-square-foot attic from bare joists (R-2) to R-60 runs an estimated $3,480, and saves about $1,268 a year in heating and cooling — a payback around 2.7 years. Hard to find a home improvement with a faster payback than this.
Where the savings come from
Of that, about $961/year comes from reduced heating and $306/year from reduced cooling load through the ceiling. Pemiscot County beats 36% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 825 counties DOE places in zone 4, Pemiscot County ranks 644th. Against Missouri's own average of $1,534/year, Pemiscot County runs 17% below that.
Where these numbers come from
NOAA's CARUTHERSVILLE, MO US station, 7.2 miles from Pemiscot County, supplies the 3,595 HDD and 1,908 CDD this estimate runs on. By total degree days, Pemiscot County sits at the 40th percentile nationally. DOE also classifies Pemiscot County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
