Clear Creek County, CO Insulation Payback
Attic insulation payback for Clear Creek County, CO
Clear Creek County, Colorado 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. 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 $2,229 a year in heating and cooling — a payback around 1.6 years. Hard to find a home improvement with a faster payback than this.
The breakdown behind the number
Of that, about $2,222/year comes from reduced heating and $7/year from reduced cooling load through the ceiling. Clear Creek County beats 91% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 120 counties DOE places in zone 7, Clear Creek County ranks 112th. Against Colorado's own average of $2,043/year, Clear Creek County runs 9% above that.
Clear Creek County's actual weather, not a national average
Clear Creek County's climate figures — 8,312 heating and 41 cooling degree days a year — are read from GEORGETOWN, CO US, 1.9 miles away, NOAA's nearest 1991-2020 normals station. Combined heating and cooling load puts Clear Creek County in the 89th percentile of this 3,162-county dataset.
If the attic isn't bare
If Clear Creek 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 $325/year — payback about 7 years. Topping up the attic pays for itself here.
