Towner County, ND Insulation Payback
Towner County, ND: what topping up your attic actually costs
Towner County, North Dakota is zone 7 under DOE's climate map (Very Cold), which means winters long and harsh enough that heating is essentially the entire equation. 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 $2,832 a year in heating and cooling — a payback around 1.2 years. That's about as fast as attic paybacks get.
Where the savings come from
The estimated savings split roughly $2,806/year heating, $25/year cooling. Out of every 100 US counties tracked here, Towner County's savings potential beats roughly 99 of them. Within zone 7 specifically, it ranks 12th of 120 counties by estimated savings. North Dakota averages $2,496/year across the counties tracked here; Towner County comes in 13% higher.
The climate data behind this
Towner County's climate figures — 10,496 heating and 156 cooling degree days a year — are read from ROLLA 1NE, ND US, 20.6 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Towner County sits at the 99th percentile nationally.
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 $413/year saved (~5.5-year payback). That is a solid payback as home upgrades go.
