Pike County, IN Insulation Payback
Attic insulation payback for Pike County, IN
Pike County, Indiana 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 2.3 years at an estimated $1,520/year saved. Hard to find a home improvement with a faster payback than this.
Where the savings come from
Of that, about $1,354/year comes from reduced heating and $166/year from reduced cooling load through the ceiling. Pike County beats 54% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 825 counties DOE places in zone 4, Pike County ranks 142nd. Against Indiana's own average of $1,634/year, Pike County runs 7% below that.
Pike County's actual weather, not a national average
The heating and cooling degree days behind this estimate — 5,064 HDD and 1,033 CDD (base 65°F, 1991-2020 normals) — come from PETERSBURG 61 BRG, IN US, the nearest NOAA station with published normals, 5 miles from Pike County's center. Combined heating and cooling load puts Pike County in the 54th percentile of this 3,162-county dataset. DOE also classifies Pike County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
The smaller top-up scenario
If Pike 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 $222/year — payback about 10.3 years. It is close - the payback only just fits a reasonable timeframe.
