Aleutians East Borough, AK Insulation Payback
Attic insulation payback for Aleutians East Borough, AK
Aleutians East Borough sits in IECC climate zone 7 (Very Cold) — severe, long winters where heating is nearly the whole story. 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 $2,504 a year in heating and cooling — a payback around 1.4 years. Hard to find a home improvement with a faster payback than this.
Heating vs. cooling in Aleutians East Borough
Nearly all of that is heating savings ($2,504/year) — Aleutians East Borough's cooling load through the ceiling is negligible. Aleutians East Borough beats 97% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 120 counties DOE places in zone 7, Aleutians East Borough ranks 65th. Against Alaska's own average of $2,854/year, Aleutians East Borough runs 12% below that.
Where these numbers come from
Aleutians East Borough's climate figures — 9,363 heating and 0 cooling degree days a year — are read from COLD BAY AP, AK US, 29 miles away, NOAA's nearest 1991-2020 normals station. That combined heating-and-cooling load ranks Aleutians East Borough 100th nationally by total degree days — the 97th percentile.
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 $365/year saved (~6.2-year payback). Topping up the attic pays for itself here.
Getting it done in Aleutians East Borough
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 Aleutians East Borough, not a bid - contractors typically charge a $600 minimum regardless of job size.
