Clare County, MI Insulation Payback
Clare County attic insulation, by the numbers
Clare County, Michigan is zone 6 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. 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 $2,054 a year in heating and cooling — a payback around 1.7 years. Topping up the attic pays for itself fast here.
Heating vs. cooling in Clare County
Split it out and it's roughly $1,985 a year on the heating side, $69 on cooling. By estimated insulation savings, Clare County lands in the 84th percentile nationally. Zone 6 alone covers 459 counties in this dataset, and Clare County comes in 345th by savings. Michigan averages $2,064/year across the counties tracked here; Clare County comes in 0% higher.
Where these numbers come from
Clare County's climate figures — 7,425 heating and 428 cooling degree days a year — are read from GLADWIN, MI US, 17.3 miles away, NOAA's nearest 1991-2020 normals station. That combined heating-and-cooling load ranks Clare County 501st nationally by total degree days — the 84th percentile. One local detail the R-value alone won't tell you: Clare County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
The smaller top-up scenario
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $300/year saved — roughly 7.6 years to break even. Worth doing on the numbers alone.
