Clarion County, PA Insulation Payback
Clarion County attic insulation, by the numbers
Clarion County, Pennsylvania is zone 5 under DOE's climate map (Cold), which means a real winter that drives most of the annual energy bill here. An uninsulated attic there should be built up to R-60. Topping up a typical 1,000-square-foot attic from bare joists (R-2) to R-60 runs an estimated $3,480, and saves about $1,866 a year in heating and cooling — a payback around 1.9 years. Topping up the attic pays for itself fast here.
Where the savings come from
Split it out and it's roughly $1,794 a year on the heating side, $72 on cooling. By estimated insulation savings, Clarion County lands in the 76th percentile nationally. Zone 5 alone covers 745 counties in this dataset, and Clarion County comes in 183rd by savings. Pennsylvania averages $1,724/year across the counties tracked here; Clarion County comes in 8% higher.
Where these numbers come from
Clarion County's climate figures — 6,709 heating and 448 cooling degree days a year — are read from CLARION 3 SW, PA US, 0.9 miles away, NOAA's nearest 1991-2020 normals station. That combined heating-and-cooling load ranks Clarion County 810th nationally by total degree days — the 74th percentile. One local detail the R-value alone won't tell you: Clarion County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
The smaller top-up scenario
If Clarion 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 $272/year — payback about 8.4 years. Call this borderline rather than a clear win.
Quotes and materials for this job
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 Clarion County job, not a quote. Expect at least a $600 minimum charge from most contractors.
Where these figures come from
Clarion 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.
