Labette County, KS Insulation Payback
Labette County, KS: what topping up your attic actually costs
Labette County, Kansas is zone 4 under DOE's climate map (Mixed-Humid), which means heating load in winter and cooling load in summer, both worth taking seriously here. An uninsulated attic there should be built 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 2.3 years at an estimated $1,485/year saved. That's about as fast as attic paybacks get.
Where the savings come from
The estimated savings split roughly $1,254/year heating, $231/year cooling. Out of every 100 US counties tracked here, Labette County's savings potential beats roughly 52 of them. Within zone 4 specifically, it ranks 199th of 825 counties by estimated savings. Kansas averages $1,594/year across the counties tracked here; Labette County comes in 7% lower.
Where these numbers come from
Labette County's climate figures — 4,690 heating and 1,440 cooling degree days a year — are read from MOUND VALLEY 3 WSW, KS US, 8.4 miles away, NOAA's nearest 1991-2020 normals station. That combined heating-and-cooling load ranks Labette County 1438th nationally by total degree days — the 55th percentile. Labette 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?
If Labette 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 $217/year — payback about 10.5 years. This one is a genuine toss-up, not a clear yes.
