Beckham County, OK Insulation Payback
Beckham County attic insulation, by the numbers
DOE classifies Beckham County as climate zone 3, mixed-humid — a genuine mix of cold winters and humid summers, with neither one dominating the bill. Its recommended attic R-value for bare joists is R-49. Going from R-2 to the recommended R-49 costs roughly $2,820 installed for a typical attic (about 1,000 sq ft), and pays for itself in about 2.1 years at an estimated $1,316/year saved. Topping up the attic pays for itself fast here.
The breakdown behind the number
Split it out and it's roughly $1,017 a year on the heating side, $299 on cooling. By estimated insulation savings, Beckham County lands in the 40th percentile nationally. Zone 3 alone covers 690 counties in this dataset, and Beckham County comes in 24th by savings. Oklahoma averages $1,260/year across the counties tracked here; Beckham County comes in 4% higher.
Beckham County's actual weather, not a national average
NOAA's ERICK 4ESE MESONET, OK US station, 7.8 miles from Beckham County, supplies the 3,833 HDD and 1,878 CDD this estimate runs on. Combined heating and cooling load puts Beckham County in the 45th percentile of this 3,162-county dataset. One local detail the R-value alone won't tell you: Beckham County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
Already have some insulation?
A shallower starting point changes the math: with R-11 already down, only the gap to R-38 needs filling, at roughly $1,620 for an estimated $177/year saved (~9.1-year payback). Call this borderline rather than a clear win.
Getting it done in Beckham County
Get more than one quote before committing. Attic access and any needed air sealing move the price around, and most contractors won't take a job below roughly $600 regardless of size - worth asking upfront given Beckham County's estimated $1,316/year on the line.
Where these figures come from
Beckham County's R-49 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-49 is the target here specifically.
