Routt County, CO Insulation Payback
Is attic insulation worth it in Routt County, CO?
Routt County, Colorado is zone 7 under DOE's climate map (Very Cold), which means winters long and harsh enough that heating is essentially the entire equation. An uninsulated attic there should be built up to 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 $2,384 a year in heating and cooling — a payback around 1.5 years. Few home upgrades pay back that quickly.
