Morris County, KS Insulation Payback

Is attic insulation worth it in Morris County, KS?

DOE classifies Morris County as climate zone 4, mixed-humid — heating load in winter and cooling load in summer, both worth taking seriously here. 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 $1,568 a year — payback in roughly 2.2 years. Few home upgrades pay back that quickly.

Where the savings come from

Heating accounts for about $1,323/year of that and cooling about $245/year — Morris County needs both. Nationally, Morris County ranks in the 57th percentile for insulation savings potential. Compared only against its own climate zone, Morris County places 80th out of 825. Against Kansas's own average of $1,594/year, Morris County runs 2% below that.

Morris County's actual weather, not a national average

The heating and cooling degree days behind this estimate — 4,948 HDD and 1,523 CDD (base 65°F, 1991-2020 normals) — come from COUNCIL GROVE LAKE, KS US, the nearest NOAA station with published normals, 7.7 miles from Morris County's center. That combined heating-and-cooling load ranks Morris County 1228th nationally by total degree days — the 61th percentile. Its moisture regime is classified humid, which matters for whether the attic needs a vapor retarder as part of the job — worth asking a contractor about locally.

If the attic isn't bare

If Morris 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 $229/year — payback about 10 years. Whether that is worth it depends on how long you plan to stay.
