Lincoln County, WV Insulation Payback
Attic insulation payback for Lincoln County, WV
Lincoln County, West Virginia is zone 4 under DOE's climate map (Mixed-Humid), which means heating load in winter and cooling load in summer, both worth taking seriously here. An uninsulated attic there should be built up to R-60. Going from R-2 to the recommended R-60 costs roughly $3,480 installed for a typical attic (about 1,000 sq ft), and pays for itself in about 2.5 years at an estimated $1,411/year saved. Hard to find a home improvement with a faster payback than this.
The breakdown behind the number
Of that, about $1,219/year comes from reduced heating and $192/year from reduced cooling load through the ceiling. Lincoln County beats 46% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 825 counties DOE places in zone 4, Lincoln County ranks 365th. Against West Virginia's own average of $1,526/year, Lincoln County runs 8% below that.
The climate data behind this
The heating and cooling degree days behind this estimate — 4,559 HDD and 1,196 CDD (base 65°F, 1991-2020 normals) — come from HAMLIN, WV US, the nearest NOAA station with published normals, 7.7 miles from Lincoln County's center. That combined heating-and-cooling load ranks Lincoln County 1704th nationally by total degree days — the 46th percentile. DOE also classifies Lincoln County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
Already have some insulation?
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $206/year saved — roughly 11.1 years to break even. It is close - the payback only just fits a reasonable timeframe.
