Las Animas County, CO Insulation Payback
Attic insulation payback for Las Animas County, CO
Las Animas County, Colorado is zone 4 under DOE's climate map (Mixed-Dry), which means big seasonal swings - a dry hot summer, then a real winter cold snap. An uninsulated attic there should be built 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 2.2 years at an estimated $1,551/year saved. Hard to find a home improvement with a faster payback than this.
Where the savings come from
Of that, about $1,410/year comes from reduced heating and $141/year from reduced cooling load through the ceiling. Las Animas County beats 56% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 825 counties DOE places in zone 4, Las Animas County ranks 97th. Against Colorado's own average of $2,043/year, Las Animas County runs 24% below that.
Where these numbers come from
Las Animas County's climate figures — 5,272 heating and 877 cooling degree days a year — are read from TRINIDAD PERRY STOKES AP, CO US, 16.6 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Las Animas County sits at the 55th percentile nationally. DOE also classifies Las Animas County as moisture regime B (dry) - ask a local contractor whether that changes the vapor-barrier approach for this job.
Already have some insulation?
If Las Animas County's attic already has 3-4 inches of old insulation (about R-11) rather than bare joists, the recommended target drops to R-49. That smaller top-up costs around $2,280 and saves an estimated $226/year — payback about 10.1 years. It is close - the payback only just fits a reasonable timeframe.
