Beaver County, OK Insulation Payback
Beaver County attic insulation, by the numbers
DOE classifies Beaver County as climate zone 4, mixed-dry — big seasonal swings - a dry hot summer, then a real winter cold snap. Its recommended attic R-value for bare joists is 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 $1,507 a year — payback in roughly 2.3 years. Topping up the attic pays for itself fast here.
Heating vs. cooling in Beaver County
Split it out and it's roughly $1,250 a year on the heating side, $257 on cooling. By estimated insulation savings, Beaver County lands in the 53th percentile nationally. Zone 4 alone covers 825 counties in this dataset, and Beaver County comes in 163rd by savings. Oklahoma averages $1,260/year across the counties tracked here; Beaver County comes in 20% higher.
Where these numbers come from
Beaver County's climate figures — 4,674 heating and 1,600 cooling degree days a year — are read from BEAVER, OK US, 5.2 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Beaver County sits at the 58th percentile nationally. One local detail the R-value alone won't tell you: Beaver County sits in moisture regime B (dry), which can affect the vapor-barrier choice.
The smaller top-up scenario
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 $220/year — payback about 10.4 years. Call this borderline rather than a clear win.
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.
Where these figures come from
Beaver County's R-60 target and its degree-day figures both come from named federal sources - see the methodology guide for exactly which ones. The guide to what R-value actually means explains why R-60 is the target here specifically.
