Beaver County, UT Insulation Payback
Attic insulation payback for Beaver County, UT
DOE classifies Beaver County as climate zone 5, cold — winters that dominate the energy bill, with cooling a minor factor. Its recommended attic R-value for bare joists is 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 $1,607 a year in heating and cooling — a payback around 2.2 years. Hard to find a home improvement with a faster payback than this.
Heating vs. cooling in Beaver County
Of that, about $1,475/year comes from reduced heating and $133/year from reduced cooling load through the ceiling. Beaver County beats 60% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 745 counties DOE places in zone 5, Beaver County ranks 636th. Against Utah's own average of $1,791/year, Beaver County runs 10% below that.
The climate data behind this
The heating and cooling degree days behind this estimate — 5,515 HDD and 827 CDD (base 65°F, 1991-2020 normals) — come from MILFORD, UT US, the nearest NOAA station with published normals, 12.5 miles from Beaver County's center. By total degree days, Beaver County sits at the 59th percentile nationally. DOE also classifies Beaver County as moisture regime B (dry) - ask a local contractor whether that changes the vapor-barrier approach for this job.
If the attic isn't bare
If Beaver 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 $234/year — payback about 9.7 years. It is close - the payback only just fits a reasonable timeframe.
Quotes and materials for this job
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 Beaver County, not a bid - contractors typically charge a $600 minimum regardless of job size.
