Garfield County, NE Insulation Payback
Garfield County attic insulation, by the numbers
Garfield County sits in IECC climate zone 5 (Cold) — winters that dominate the energy bill, with cooling a minor factor. 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 1.8 years at an estimated $1,976/year saved. Topping up the attic pays for itself fast here.
The breakdown behind the number
Split it out and it's roughly $1,859 a year on the heating side, $118 on cooling. By estimated insulation savings, Garfield County lands in the 81th percentile nationally. Zone 5 alone covers 745 counties in this dataset, and Garfield County comes in 64th by savings. Nebraska averages $1,872/year across the counties tracked here; Garfield County comes in 6% higher.
Garfield County's actual weather, not a national average
The heating and cooling degree days behind this estimate — 6,952 HDD and 732 CDD (base 65°F, 1991-2020 normals) — come from ERICSON 8 WNW, NE US, the nearest NOAA station with published normals, 9.7 miles from Garfield County's center. That combined heating-and-cooling load ranks Garfield County 571st nationally by total degree days — the 82th percentile. One local detail the R-value alone won't tell you: Garfield County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
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 $288/year saved — roughly 7.9 years to break even. Worth doing on the numbers alone.
Getting it done in Garfield County
Get more than one quote before committing. Attic access and any needed air sealing move the price around, and most contractors won't take a job below roughly $600 regardless of size - worth asking upfront given Garfield County's estimated $1,976/year on the line.
Where these figures come from
Garfield 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.
