Sheboygan County, WI Insulation Payback
Attic insulation payback for Sheboygan County, WI
Sheboygan County, Wisconsin is zone 6 under DOE's climate map (Cold), which means cold enough that heating, not cooling, is what decides the bill. An uninsulated attic there should be built 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 $1,947 a year — payback in roughly 1.8 years. Hard to find a home improvement with a faster payback than this.
Heating vs. cooling in Sheboygan County
Of that, about $1,850/year comes from reduced heating and $97/year from reduced cooling load through the ceiling. Sheboygan County beats 79% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 459 counties DOE places in zone 6, Sheboygan County ranks 430th. Against Wisconsin's own average of $2,200/year, Sheboygan County runs 11% below that.
Where these numbers come from
Sheboygan County's climate figures — 6,919 heating and 603 cooling degree days a year — are read from SHEBOYGAN, WI US, 1.1 miles away, NOAA's nearest 1991-2020 normals station. That combined heating-and-cooling load ranks Sheboygan County 650th nationally by total degree days — the 79th percentile. DOE also classifies Sheboygan County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
If the attic isn't bare
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 $284/year saved (~8-year payback). It is close - the payback only just fits a reasonable timeframe.
Getting it done in Sheboygan 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 Sheboygan County, not a bid - contractors typically charge a $600 minimum regardless of job size.
