Prince of Wales-Hyder Census Area, AK Insulation Payback
Attic insulation payback for Prince of Wales-Hyder Census Area, AK
Prince of Wales-Hyder Census Area, Alaska is zone 7 under DOE's climate map (Very Cold), which means a climate where the heating season stretches across most of the year. An uninsulated attic there should be built 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 $1,930 a year — payback in roughly 1.8 years. Hard to find a home improvement with a faster payback than this.
Where the savings come from
Of that, about $1,929/year comes from reduced heating and $1/year from reduced cooling load through the ceiling. Prince of Wales-Hyder Census Area beats 79% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 120 counties DOE places in zone 7, Prince of Wales-Hyder Census Area ranks 119th. Against Alaska's own average of $2,854/year, Prince of Wales-Hyder Census Area runs 32% below that.
Prince of Wales-Hyder Census Area's actual weather, not a national average
NOAA's KLAWOCK AP, AK US station, 7.9 miles from Prince of Wales-Hyder Census Area, supplies the 7,216 HDD and 6 CDD this estimate runs on. That combined heating-and-cooling load ranks Prince of Wales-Hyder Census Area 778th nationally by total degree days — the 75th percentile.
Already have some insulation?
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $282/year saved — roughly 8.1 years to break even. It is close - the payback only just fits a reasonable timeframe.
