Bollinger County, MO Insulation Payback
Attic insulation payback for Bollinger County, MO
Bollinger County sits in IECC climate zone 4 (Mixed-Humid) — a genuine mix of cold winters and humid summers, with neither one dominating 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 2.6 years at an estimated $1,320/year saved. Hard to find a home improvement with a faster payback than this.
Where the savings come from
Of that, about $1,075/year comes from reduced heating and $245/year from reduced cooling load through the ceiling. Bollinger County beats 40% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 825 counties DOE places in zone 4, Bollinger County ranks 544th. Against Missouri's own average of $1,534/year, Bollinger County runs 14% below that.
The climate data behind this
NOAA's MARBLE HILL, MO US station, 3.4 miles from Bollinger County, supplies the 4,020 HDD and 1,528 CDD this estimate runs on. By total degree days, Bollinger County sits at the 41th percentile nationally. DOE also classifies Bollinger 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
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $193/year saved — roughly 11.8 years to break even. It is close - the payback only just fits a reasonable timeframe.
