Perkins County, NE Insulation Payback
Perkins County attic insulation, by the numbers
Perkins County sits in IECC climate zone 5 (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. For an attic around 1,000 square feet, closing the gap from R-2 to R-60 costs around $3,480 and saves an estimated $1,855 a year — payback in roughly 1.9 years. Topping up the attic pays for itself fast here.
Where the savings come from
Split it out and it's roughly $1,710 a year on the heating side, $144 on cooling. By estimated insulation savings, Perkins County lands in the 75th percentile nationally. Zone 5 alone covers 745 counties in this dataset, and Perkins County comes in 199th by savings. Nebraska averages $1,872/year across the counties tracked here; Perkins County comes in 1% lower.
Where these numbers come from
Perkins County's climate figures — 6,397 heating and 898 cooling degree days a year — are read from MADRID, NE US, 4.5 miles away, NOAA's nearest 1991-2020 normals station. That combined heating-and-cooling load ranks Perkins County 743rd nationally by total degree days — the 77th percentile. One local detail the R-value alone won't tell you: Perkins County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
The smaller top-up scenario
If Perkins 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 $271/year — payback about 8.4 years. Call this borderline rather than a clear win.
Getting it done in Perkins County
Actual quotes will vary by attic access, existing debris, and whether the job needs air sealing first. Treat the $3,480 figure above as a planning number for Perkins County, not a bid - contractors typically charge a $600 minimum regardless of job size.
Where these figures come from
Perkins County's R-60 target and its degree-day figures both come from named federal sources - see the methodology guide for exactly which ones. The guide to what R-value actually means explains why R-60 is the target here specifically.
