Wyoming County, PA Insulation Payback
Wyoming County, PA: what topping up your attic actually costs
DOE classifies Wyoming County as climate zone 5, cold — cold enough that heating, not cooling, is what decides the bill. Its recommended attic R-value for bare joists is 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 $1,662 a year in heating and cooling — a payback around 2.1 years. That's about as fast as attic paybacks get.
The breakdown behind the number
The estimated savings split roughly $1,535/year heating, $127/year cooling. Out of every 100 US counties tracked here, Wyoming County's savings potential beats roughly 64 of them. Within zone 5 specifically, it ranks 551st of 745 counties by estimated savings. Pennsylvania averages $1,724/year across the counties tracked here; Wyoming County comes in 4% lower.
Where these numbers come from
Wyoming County's climate figures — 5,740 heating and 791 cooling degree days a year — are read from WILKES-BARRE INTL AP, PA US, 19.7 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Wyoming County sits at the 62th percentile nationally. Wyoming County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
Already have some insulation?
A shallower starting point changes the math: with R-11 already down, only the gap to R-49 needs filling, at roughly $2,280 for an estimated $242/year saved (~9.4-year payback). This one is a genuine toss-up, not a clear yes.
Next steps for a Wyoming County attic
Actual quotes will vary by attic access, existing debris, and whether the job needs air sealing first. Treat the $3,480 figure above as a planning number for Wyoming County, not a bid - contractors typically charge a $600 minimum regardless of job size.
Nothing here is a guess
Every figure on this page traces to DOE/IECC climate zones and NOAA degree-day normals, documented in the methodology guide. The guide to what R-value actually means explains why R-60 is the target here specifically.
