Goshen County, WY Insulation Payback
Is attic insulation worth it in Goshen County, WY?
Goshen 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 $1,964 a year — payback in roughly 1.8 years. Few home upgrades pay back that quickly.
Where the savings come from
Heating accounts for about $1,886/year of that and cooling about $78/year — Goshen County needs both. Nationally, Goshen County ranks in the 80th percentile for insulation savings potential. Compared only against its own climate zone, Goshen County places 79th out of 745. Against Wyoming's own average of $2,161/year, Goshen County runs 9% below that.
Goshen County's actual weather, not a national average
Goshen County's climate figures — 7,055 heating and 483 cooling degree days a year — are read from LINGLE 2WSW, WY US, 3.4 miles away, NOAA's nearest 1991-2020 normals station. Combined heating and cooling load puts Goshen County in the 80th percentile of this 3,162-county dataset. Its moisture regime is classified dry, which matters for whether the attic needs a vapor retarder as part of the job — worth asking a contractor about locally.
The smaller top-up scenario
If Goshen 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 $286/year — payback about 8 years. The math clears comfortably within a normal ownership horizon.
Getting it done in Goshen 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 Goshen County, not a bid - contractors typically charge a $600 minimum regardless of job size.
