Kit Carson County, CO Insulation Payback
Kit Carson County attic insulation, by the numbers
DOE classifies Kit Carson 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. 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 $1,701/year saved. Topping up the attic pays for itself fast here.
Heating vs. cooling in Kit Carson County
Split it out and it's roughly $1,556 a year on the heating side, $145 on cooling. By estimated insulation savings, Kit Carson County lands in the 66th percentile nationally. Zone 5 alone covers 745 counties in this dataset, and Kit Carson County comes in 485th by savings. Colorado averages $2,043/year across the counties tracked here; Kit Carson County comes in 17% lower.
The climate data behind this
The heating and cooling degree days behind this estimate — 5,821 HDD and 901 CDD (base 65°F, 1991-2020 normals) — come from STRATTON, CO US, the nearest NOAA station with published normals, 0.2 miles from Kit Carson County's center. Combined heating and cooling load puts Kit Carson County in the 66th percentile of this 3,162-county dataset. One local detail the R-value alone won't tell you: Kit Carson 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 $248/year saved — roughly 9.2 years to break even. Call this borderline rather than a clear win.
Next steps for a Kit Carson County attic
Get more than one quote before committing. Attic access and any needed air sealing move the price around, and most contractors won't take a job below roughly $600 regardless of size - worth asking upfront given Kit Carson County's estimated $1,701/year on the line.
Where these figures come from
Kit Carson 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.
