Thomas County, NE Insulation Payback
Thomas County, NE: what topping up your attic actually costs
Thomas County sits in IECC climate zone 5 (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 1.8 years at an estimated $1,912/year saved. That's about as fast as attic paybacks get.
Heating vs. cooling in Thomas County
The estimated savings split roughly $1,787/year heating, $124/year cooling. Out of every 100 US counties tracked here, Thomas County's savings potential beats roughly 78 of them. Within zone 5 specifically, it ranks 135th of 745 counties by estimated savings. Nebraska averages $1,872/year across the counties tracked here; Thomas County comes in 2% higher.
The climate data behind this
NOAA's PURDUM, NE US station, 20.3 miles from Thomas County, supplies the 6,684 HDD and 774 CDD this estimate runs on. Combined heating and cooling load puts Thomas County in the 79th percentile of this 3,162-county dataset. Thomas County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
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 $279/year saved — roughly 8.2 years to break even. This one is a genuine toss-up, not a clear yes.
