Muskingum County, OH Insulation Payback
Muskingum County attic insulation, by the numbers
Muskingum County sits in IECC climate zone 5 (Cold) — winters that dominate the energy bill, with cooling a minor factor. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to 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 $1,555 a year in heating and cooling — a payback around 2.2 years. Topping up the attic pays for itself fast here.
Where the savings come from
Split it out and it's roughly $1,409 a year on the heating side, $147 on cooling. By estimated insulation savings, Muskingum County lands in the 57th percentile nationally. Zone 5 alone covers 745 counties in this dataset, and Muskingum County comes in 688th by savings. Ohio averages $1,669/year across the counties tracked here; Muskingum County comes in 7% lower.
The climate data behind this
The heating and cooling degree days behind this estimate — 5,268 HDD and 914 CDD (base 65°F, 1991-2020 normals) — come from ZANESVILLE MUNI AP, OH US, the nearest NOAA station with published normals, 3.1 miles from Muskingum County's center. By total degree days, Muskingum County sits at the 56th percentile nationally. One local detail the R-value alone won't tell you: Muskingum County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
If the attic isn't bare
If Muskingum 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 $227/year — payback about 10 years. Call this borderline rather than a clear win.
Getting it done in Muskingum County
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 Muskingum County's estimated $1,555/year on the line.
Where these figures come from
Muskingum County's R-60 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-60 is the target here specifically.
