Gentry County, MO Insulation Payback
Gentry County attic insulation, by the numbers
DOE classifies Gentry County as climate zone 5, cold — winters that dominate the energy bill, with cooling a minor factor. Its recommended attic R-value for bare joists is 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 years at an estimated $1,745/year saved. Topping up the attic pays for itself fast here.
The breakdown behind the number
Split it out and it's roughly $1,552 a year on the heating side, $194 on cooling. By estimated insulation savings, Gentry County lands in the 69th percentile nationally. Zone 5 alone covers 745 counties in this dataset, and Gentry County comes in 399th by savings. Missouri averages $1,534/year across the counties tracked here; Gentry County comes in 14% higher.
Gentry County's actual weather, not a national average
Gentry County's climate figures — 5,804 heating and 1,205 cooling degree days a year — are read from ALBANY, MO US, 4.8 miles away, NOAA's nearest 1991-2020 normals station. That combined heating-and-cooling load ranks Gentry County 903rd nationally by total degree days — the 71th percentile. One local detail the R-value alone won't tell you: Gentry County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
Already have some insulation?
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $255/year saved — roughly 9 years to break even. Call this borderline rather than a clear win.
Next steps for a Gentry County attic
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 Gentry County job, not a quote. Expect at least a $600 minimum charge from most contractors.
Where these figures come from
Gentry 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.
