Emmons County, ND Insulation Payback

Emmons County attic insulation, by the numbers

Emmons County, North Dakota is zone 6 under DOE's climate map (Cold), which means cold enough that heating, not cooling, is what decides the bill. 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 $2,398 a year in heating and cooling — a payback around 1.5 years. Topping up the attic pays for itself fast here.

The breakdown behind the number

Split it out and it's roughly $2,300 a year on the heating side, $98 on cooling. By estimated insulation savings, Emmons County lands in the 96th percentile nationally. Zone 6 alone covers 459 counties in this dataset, and Emmons County comes in 32nd by savings. North Dakota averages $2,496/year across the counties tracked here; Emmons County comes in 4% lower.

The climate data behind this

NOAA's LINTON, ND US station, 1.3 miles from Emmons County, supplies the 8,602 HDD and 609 CDD this estimate runs on. That combined heating-and-cooling load ranks Emmons County 121st nationally by total degree days — the 96th percentile. One local detail the R-value alone won't tell you: Emmons County sits in moisture regime A (humid), which can affect the vapor-barrier choice.

Already have some insulation?

Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $350/year saved — roughly 6.5 years to break even. Worth doing on the numbers alone.

Quotes and materials for this job

Real bids depend on how easy the attic is to reach and whether old insulation needs removing first, so treat $3,480 as a starting estimate for a Emmons County job, not a quote. Expect at least a $600 minimum charge from most contractors.
