Burke County, ND Insulation Payback
Burke County, ND: what topping up your attic actually costs
Burke County, North Dakota is zone 7 under DOE's climate map (Very Cold), which means severe, long winters where heating is nearly the whole story. An uninsulated attic there should be built 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 1.3 years at an estimated $2,728/year saved. That's about as fast as attic paybacks get.
Heating vs. cooling in Burke County
The estimated savings split roughly $2,681/year heating, $47/year cooling. Out of every 100 US counties tracked here, Burke County's savings potential beats roughly 99 of them. Within zone 7 specifically, it ranks 18th of 120 counties by estimated savings. North Dakota averages $2,496/year across the counties tracked here; Burke County comes in 9% higher.
The climate data behind this
Burke County's climate figures — 10,028 heating and 290 cooling degree days a year — are read from POWERS LAKE 1N, ND US, 15.9 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Burke County sits at the 99th percentile nationally.
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 $398/year saved — roughly 5.7 years to break even. That is a solid payback as home upgrades go.
