Lincoln County, CO Insulation Payback
Lincoln County attic insulation, by the numbers
DOE classifies Lincoln 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. Topping up a typical 1,000-square-foot attic from bare joists (R-2) to R-60 runs an estimated $3,480, and saves about $1,795 a year in heating and cooling — a payback around 1.9 years. Topping up the attic pays for itself fast here.
The breakdown behind the number
Split it out and it's roughly $1,698 a year on the heating side, $97 on cooling. By estimated insulation savings, Lincoln County lands in the 72th percentile nationally. Zone 5 alone covers 745 counties in this dataset, and Lincoln County comes in 305th by savings. Colorado averages $2,043/year across the counties tracked here; Lincoln County comes in 12% lower.
Where these numbers come from
Lincoln County's climate figures — 6,349 heating and 605 cooling degree days a year — are read from HUGO 1 NW, CO US, 10.4 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Lincoln County sits at the 70th percentile nationally. One local detail the R-value alone won't tell you: Lincoln County sits in moisture regime B (dry), which can affect the vapor-barrier choice.
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 $262/year saved — roughly 8.7 years to break even. Call this borderline rather than a clear win.
Next steps for a Lincoln 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 Lincoln County job, not a quote. Expect at least a $600 minimum charge from most contractors.
Where these figures come from
Lincoln 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.
