Panola County, MS Insulation Payback
Panola County attic insulation, by the numbers
Panola County, Mississippi 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. 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 $1,134 a year — payback in roughly 2.5 years. Topping up the attic pays for itself fast here.
The breakdown behind the number
Split it out and it's roughly $824 a year on the heating side, $310 on cooling. By estimated insulation savings, Panola County lands in the 27th percentile nationally. Zone 3 alone covers 690 counties in this dataset, and Panola County comes in 182nd by savings. Mississippi averages $1,022/year across the counties tracked here; Panola County comes in 11% higher.
The climate data behind this
Panola County's climate figures — 3,106 heating and 1,945 cooling degree days a year — are read from BATESVILLE 2 SW, MS US, 4.2 miles away, NOAA's nearest 1991-2020 normals station. Combined heating and cooling load puts Panola County in the 27th percentile of this 3,162-county dataset. One local detail the R-value alone won't tell you: Panola County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
If the attic isn't bare
Already have a few inches up there? Topping R-11 up to R-38 runs about $1,620 for about $153/year saved — roughly 10.6 years to break even. Call this borderline rather than a clear win.
Getting it done in Panola County
Real bids depend on how easy the attic is to reach and whether old insulation needs removing first, so treat $2,820 as a starting estimate for a Panola County job, not a quote. Expect at least a $600 minimum charge from most contractors.
Where these figures come from
Panola 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.
