Cedar County, NE Insulation Payback
Attic insulation payback for Cedar County, NE
DOE classifies Cedar County as climate zone 5, cold — cold enough that heating, not cooling, is what decides the bill. Its recommended attic R-value for bare joists is R-60. For an attic around 1,000 square feet, closing the gap from R-2 to R-60 costs around $3,480 and saves an estimated $2,009 a year — payback in roughly 1.7 years. Hard to find a home improvement with a faster payback than this.
Where the savings come from
Of that, about $1,878/year comes from reduced heating and $130/year from reduced cooling load through the ceiling. Cedar County beats 83% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 745 counties DOE places in zone 5, Cedar County ranks 38th. Against Nebraska's own average of $1,872/year, Cedar County runs 7% above that.
Cedar County's actual weather, not a national average
NOAA's HARTINGTON, NE US station, 0.9 miles from Cedar County, supplies the 7,025 HDD and 811 CDD this estimate runs on. By total degree days, Cedar County sits at the 84th percentile nationally. DOE also classifies Cedar 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 $293/year saved — roughly 7.8 years to break even. Topping up the attic pays for itself here.
