La Crosse County, WI Insulation Payback
La Crosse County attic insulation, by the numbers
La Crosse 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. Going from R-2 to the recommended R-60 costs roughly $3,480 installed for a typical attic (about 1,000 sq ft), and pays for itself in about 1.6 years at an estimated $2,117/year saved. Topping up the attic pays for itself fast here.
Heating vs. cooling in La Crosse County
Split it out and it's roughly $2,030 a year on the heating side, $87 on cooling. By estimated insulation savings, La Crosse County lands in the 87th percentile nationally. Zone 6 alone covers 459 counties in this dataset, and La Crosse County comes in 280th by savings. Wisconsin averages $2,200/year across the counties tracked here; La Crosse County comes in 4% lower.
La Crosse County's actual weather, not a national average
NOAA's LA CROSSE WFO, WI US station, 7.1 miles from La Crosse County, supplies the 7,593 HDD and 543 CDD this estimate runs on. That combined heating-and-cooling load ranks La Crosse County 396th nationally by total degree days — the 88th percentile. One local detail the R-value alone won't tell you: La Crosse County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
The smaller top-up scenario
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 $309/year saved (~7.4-year payback). Worth doing on the numbers alone.
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 La Crosse County job, not a quote. Expect at least a $600 minimum charge from most contractors.
Where these figures come from
La Crosse 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.
