Richland County, WI Insulation Payback
Richland County attic insulation, by the numbers
Richland County sits in IECC climate zone 6 (Cold) — cold enough that heating, not cooling, is what decides the bill. 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 $2,089 a year — payback in roughly 1.7 years. Topping up the attic pays for itself fast here.
Where the savings come from
Split it out and it's roughly $2,005 a year on the heating side, $84 on cooling. By estimated insulation savings, Richland County lands in the 86th percentile nationally. Zone 6 alone covers 459 counties in this dataset, and Richland County comes in 305th by savings. Wisconsin averages $2,200/year across the counties tracked here; Richland County comes in 5% lower.
Richland County's actual weather, not a national average
The heating and cooling degree days behind this estimate — 7,498 HDD and 522 CDD (base 65°F, 1991-2020 normals) — come from RICHLAND CTR, WI US, the nearest NOAA station with published normals, 3.9 miles from Richland County's center. By total degree days, Richland County sits at the 86th percentile nationally. One local detail the R-value alone won't tell you: Richland County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
Already have some insulation?
If Richland 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 $305/year — payback about 7.5 years. Worth doing on the numbers alone.
Getting it done in Richland County
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 Richland County, not a bid - contractors typically charge a $600 minimum regardless of job size.
Where these figures come from
Richland 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.
