Presque Isle County, MI Insulation Payback
Presque Isle County attic insulation, by the numbers
Presque Isle County sits in IECC climate zone 6 (Cold) — a real winter that drives most of the annual energy bill here. For a currently uninsulated attic, DOE and ENERGY STAR recommend building 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 1.6 years at an estimated $2,226/year saved. Topping up the attic pays for itself fast here.
Where the savings come from
Split it out and it's roughly $2,174 a year on the heating side, $53 on cooling. By estimated insulation savings, Presque Isle County lands in the 91th percentile nationally. Zone 6 alone covers 459 counties in this dataset, and Presque Isle County comes in 166th by savings. Michigan averages $2,064/year across the counties tracked here; Presque Isle County comes in 8% higher.
Where these numbers come from
NOAA's ALPENA 10NW, MI US station, 9.9 miles from Presque Isle County, supplies the 8,129 HDD and 327 CDD this estimate runs on. Combined heating and cooling load puts Presque Isle County in the 90th percentile of this 3,162-county dataset. One local detail the R-value alone won't tell you: Presque Isle County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
Already have some insulation?
A shallower starting point changes the math: with R-11 already down, only the gap to R-49 needs filling, at roughly $2,280 for an estimated $325/year saved (~7-year payback). Worth doing on the numbers alone.
