Henry County, IN Insulation Payback
Henry County attic insulation, by the numbers
Henry County sits in IECC climate zone 5 (Cold) — winters that dominate the energy bill, with cooling a minor factor. For a currently uninsulated attic, DOE and ENERGY STAR recommend building 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 $1,727 a year — payback in roughly 2 years. Topping up the attic pays for itself fast here.
Where the savings come from
Split it out and it's roughly $1,609 a year on the heating side, $118 on cooling. By estimated insulation savings, Henry County lands in the 68th percentile nationally. Zone 5 alone covers 745 counties in this dataset, and Henry County comes in 427th by savings. Indiana averages $1,634/year across the counties tracked here; Henry County comes in 6% higher.
Where these numbers come from
Henry County's climate figures — 6,018 heating and 737 cooling degree days a year — are read from NEW CASTLE 3 SW, IN US, 2.4 miles away, NOAA's nearest 1991-2020 normals station. That combined heating-and-cooling load ranks Henry County 1048th nationally by total degree days — the 67th percentile. One local detail the R-value alone won't tell you: Henry County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
If the attic isn't bare
If Henry 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 $252/year — payback about 9 years. Call this borderline rather than a clear win.
Next steps for a Henry County attic
Real bids depend on how easy the attic is to reach and whether old insulation needs removing first, so treat $3,480 as a starting estimate for a Henry County job, not a quote. Expect at least a $600 minimum charge from most contractors.
Where these figures come from
Henry County's R-60 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-60 is the target here specifically.
