Ballard County, KY Insulation Payback
Attic insulation payback for Ballard County, KY
DOE classifies Ballard County as climate zone 4, mixed-humid — heating load in winter and cooling load in summer, both worth taking seriously here. 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 $1,345 a year — payback in roughly 2.6 years. Hard to find a home improvement with a faster payback than this.
Heating vs. cooling in Ballard County
Of that, about $1,090/year comes from reduced heating and $256/year from reduced cooling load through the ceiling. Ballard County beats 42% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 825 counties DOE places in zone 4, Ballard County ranks 497th. Against Kentucky's own average of $1,385/year, Ballard County runs 3% below that.
Ballard County's actual weather, not a national average
NOAA's CAIRO 3N, IL US station, 9.7 miles from Ballard County, supplies the 4,075 HDD and 1,592 CDD this estimate runs on. By total degree days, Ballard County sits at the 44th percentile nationally. DOE also classifies Ballard County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
If the attic isn't bare
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $196/year saved — roughly 11.6 years to break even. It is close - the payback only just fits a reasonable timeframe.
