Gunnison County, CO Insulation Payback
Gunnison County attic insulation, by the numbers
Gunnison County sits in IECC climate zone 7 (Very Cold) — a climate where the heating season stretches across most of the year. For a currently uninsulated attic, DOE and ENERGY STAR recommend building 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 $2,659 a year in heating and cooling — a payback around 1.3 years. Topping up the attic pays for itself fast here.
The breakdown behind the number
Split it out and it's roughly $2,656 a year on the heating side, $3 on cooling. By estimated insulation savings, Gunnison County lands in the 99th percentile nationally. Zone 7 alone covers 120 counties in this dataset, and Gunnison County comes in 31st by savings. Colorado averages $2,043/year across the counties tracked here; Gunnison County comes in 30% higher.
Gunnison County's actual weather, not a national average
NOAA's GUNNISON 3SW, CO US station, 11.1 miles from Gunnison County, supplies the 9,935 HDD and 16 CDD this estimate runs on. By total degree days, Gunnison County sits at the 99th percentile nationally.
If the attic isn't bare
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 $388/year saved (~5.9-year payback). 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 Gunnison County job, not a quote. Expect at least a $600 minimum charge from most contractors.
Where these figures come from
Gunnison 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.
