Henry County, OH Insulation Payback
Henry County attic insulation, by the numbers
Henry County, Ohio is zone 5 under DOE's climate map (Cold), which means winters that dominate the energy bill, with cooling a minor factor. An uninsulated attic there should be built up to R-60. Going from R-2 to the recommended R-60 costs roughly $3,480 installed for a typical attic (about 1,000 sq ft), and pays for itself in about 1.9 years at an estimated $1,786/year saved. Topping up the attic pays for itself fast here.
The breakdown behind the number
Split it out and it's roughly $1,653 a year on the heating side, $133 on cooling. By estimated insulation savings, Henry County lands in the 71th percentile nationally. Zone 5 alone covers 745 counties in this dataset, and Henry County comes in 326th by savings. Ohio averages $1,669/year across the counties tracked here; Henry County comes in 7% higher.
Where these numbers come from
NOAA's NAPOLEON, OH US station, 4.9 miles from Henry County, supplies the 6,183 HDD and 827 CDD this estimate runs on. Combined heating and cooling load puts Henry County in the 72th percentile of this 3,162-county dataset. One local detail the R-value alone won't tell you: Henry 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-49 runs about $2,280 for about $261/year saved — roughly 8.8 years to break even. Call this borderline rather than a clear win.
Next steps for a Henry County attic
Real bids depend on how easy the attic is to reach and whether old insulation needs removing first, so treat $3,480 as a starting estimate for a Henry County job, not a quote. Expect at least a $600 minimum charge from most contractors.
