Braxton County, WV Insulation Payback
Braxton County, WV: what topping up your attic actually costs
Braxton County, West Virginia is zone 4 under DOE's climate map (Mixed-Humid), which means real heating and real cooling seasons both, roughly balanced across 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 $1,478 a year — payback in roughly 2.4 years. That's about as fast as attic paybacks get.
Heating vs. cooling in Braxton County
The estimated savings split roughly $1,323/year heating, $154/year cooling. Out of every 100 US counties tracked here, Braxton County's savings potential beats roughly 52 of them. Within zone 4 specifically, it ranks 213th of 825 counties by estimated savings. West Virginia averages $1,526/year across the counties tracked here; Braxton County comes in 3% lower.
Where these numbers come from
Braxton County's climate figures — 4,949 heating and 961 cooling degree days a year — are read from GASSAWAY, WV US, 3 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Braxton County sits at the 50th percentile nationally. Braxton County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
If the attic isn't bare
If Braxton 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 $216/year — payback about 10.6 years. This one is a genuine toss-up, not a clear yes.
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 Braxton County, not a bid - contractors typically charge a $600 minimum regardless of job size.
Nothing here is a guess
Every figure on this page traces to DOE/IECC climate zones and NOAA degree-day normals, documented in the methodology guide. The guide to what R-value actually means explains why R-60 is the target here specifically.
