Baraga County, MI Insulation Payback
Is attic insulation worth it in Baraga County, MI?
Baraga County, Michigan is zone 7 under DOE's climate map (Very Cold), which means a climate where the heating season stretches across most of the year. 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 $2,575 a year in heating and cooling — a payback around 1.4 years. Few home upgrades pay back that quickly.
Heating vs. cooling in Baraga County
Heating accounts for about $2,545/year of that and cooling about $30/year — Baraga County needs both. Nationally, Baraga County ranks in the 98th percentile for insulation savings potential. Compared only against its own climate zone, Baraga County places 48th out of 120. Against Michigan's own average of $2,064/year, Baraga County runs 25% above that.
Where these numbers come from
Baraga County's climate figures — 9,518 heating and 187 cooling degree days a year — are read from HERMAN, MI US, 2.2 miles away, NOAA's nearest 1991-2020 normals station. Combined heating and cooling load puts Baraga County in the 98th percentile of this 3,162-county dataset.
The smaller top-up scenario
If Baraga 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 $376/year — payback about 6.1 years. The math clears comfortably within a normal ownership horizon.
