Orleans County, VT Insulation Payback
Is attic insulation worth it in Orleans County, VT?
Orleans County sits in IECC climate zone 6 (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. 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 $2,366 a year in heating and cooling — a payback around 1.5 years. Few home upgrades pay back that quickly.
Heating vs. cooling in Orleans County
Heating accounts for about $2,324/year of that and cooling about $42/year — Orleans County needs both. Nationally, Orleans County ranks in the 95th percentile for insulation savings potential. Compared only against its own climate zone, Orleans County places 53rd out of 459. Against Vermont's own average of $2,179/year, Orleans County runs 9% above that.
Orleans County's actual weather, not a national average
Orleans County's climate figures — 8,691 heating and 264 cooling degree days a year — are read from NEWPORT, VT US, 8.8 miles away, NOAA's nearest 1991-2020 normals station. That combined heating-and-cooling load ranks Orleans County 174th nationally by total degree days — the 95th percentile. Its moisture regime is classified humid, which matters for whether the attic needs a vapor retarder as part of the job — worth asking a contractor about locally.
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 $345/year saved (~6.6-year payback). The math clears comfortably within a normal ownership horizon.
