Holt County, MO Insulation Payback
Holt County, MO: what topping up your attic actually costs
Holt County sits in IECC climate zone 5 (Cold) — winters that dominate the energy bill, with cooling a minor factor. 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 2 years at an estimated $1,708/year saved.
That's about as fast as attic paybacks get.
Heating vs. cooling in Holt County
The estimated savings split roughly $1,514/year heating, $194/year cooling. Out of every 100 US counties tracked here, Holt County's savings potential beats roughly 66 of them. Within zone 5 specifically, it ranks 478th of 754 counties by estimated savings. Missouri averages $1,534/year across the counties tracked here; Holt County comes in 11% higher.
The climate data behind this
Holt County's climate figures — 5,662 heating and 1,208 cooling degree days a year — are read from Oregon, MO US, 8.8 miles away, NOAA's nearest 1991-2020 normals station. That combined heating-and-cooling load ranks Holt County 1000th nationally by total degree days — the 68th percentile. Holt County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
The smaller top-up scenario
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $249/year saved — roughly 9.2 years to break even. This one is a genuine toss-up, not a clear yes.
Getting it done in Holt County
Actual quotes will vary by attic access, existing debris, and whether the job needs air sealing first, so treat the $3,480 figure above as a planning number for Holt County, not a bid. Worth getting quotes from at least two local contractors before committing - most charge a $600 minimum regardless of job size.
Nothing here is a guess
Every figure on this page traces to DOE/IECC climate zones and NOAA degree-day normals, documented in the methodology guide. The guide to what R-value actually means explains why R-60 is the target here specifically.
