Garfield County, CO Insulation Payback
Attic insulation payback for Garfield County, CO
Garfield County, Colorado is zone 5 under DOE's climate map (Cold), which means winters that dominate the energy bill, with cooling a minor factor. 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 1.8 years at an estimated $1,950/year saved. Hard to find a home improvement with a faster payback than this.
The breakdown behind the number
Of that, about $1,897/year comes from reduced heating and $53/year from reduced cooling load through the ceiling. Garfield County beats 80% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 745 counties DOE places in zone 5, Garfield County ranks 94th. Against Colorado's own average of $2,043/year, Garfield County runs 5% below that.
The climate data behind this
Garfield County's climate figures — 7,093 heating and 330 cooling degree days a year — are read from RIFLE 3ENE, CO US, 10.2 miles away, NOAA's nearest 1991-2020 normals station. Combined heating and cooling load puts Garfield County in the 78th percentile of this 3,162-county dataset. DOE also classifies Garfield County as moisture regime B (dry) - ask a local contractor whether that changes the vapor-barrier approach for this job.
Already have some insulation?
If Garfield 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 $284/year — payback about 8 years. It is close - the payback only just fits a reasonable timeframe.
