Coshocton County, OH Insulation Payback
Coshocton County, OH: what topping up your attic actually costs
DOE classifies Coshocton County as climate zone 5, cold — winters that dominate the energy bill, with cooling a minor factor. Its recommended attic R-value for bare joists is R-60. For an attic around 1,000 square feet, closing the gap from R-2 to R-60 costs around $3,480 and saves an estimated $1,635 a year — payback in roughly 2.1 years. That's about as fast as attic paybacks get.
The breakdown behind the number
The estimated savings split roughly $1,513/year heating, $121/year cooling. Out of every 100 US counties tracked here, Coshocton County's savings potential beats roughly 62 of them. Within zone 5 specifically, it ranks 596th of 745 counties by estimated savings. Ohio averages $1,669/year across the counties tracked here; Coshocton County comes in 2% lower.
Where these numbers come from
Coshocton County's climate figures — 5,660 heating and 756 cooling degree days a year — are read from COSHOCTON WPC PLT, OH US, 5 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Coshocton County sits at the 60th percentile nationally. Coshocton County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
The smaller top-up scenario
If Coshocton County's attic already has 3-4 inches of old insulation (about R-11) rather than bare joists, the recommended target drops to R-49. That smaller top-up costs around $2,280 and saves an estimated $238/year — payback about 9.6 years. This one is a genuine toss-up, not a clear yes.

Get more than one quote before committing. Attic access and any needed air sealing move the price around, and most contractors won't take a job below roughly $600 regardless of size - worth asking upfront given Coshocton County's estimated $1,635/year on the line.
Nothing here is a guess
Every figure on this page traces to DOE/IECC climate zones and NOAA degree-day normals, documented in the methodology guide. The guide to what R-value actually means explains why R-60 is the target here specifically.
