Klamath County, OR Insulation Payback

Klamath County attic insulation, by the numbers

DOE classifies Klamath County as climate zone 5, cold — a real winter that drives most of the annual energy bill 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 $1,985 a year — payback in roughly 1.8 years. Topping up the attic pays for itself fast here.

Where the savings come from

Split it out and it's roughly $1,969 a year on the heating side, $16 on cooling. By estimated insulation savings, Klamath County lands in the 81th percentile nationally. Zone 5 alone covers 745 counties in this dataset, and Klamath County comes in 58th by savings. Oregon averages $1,557/year across the counties tracked here; Klamath County comes in 27% higher.

Klamath County's actual weather, not a national average

NOAA's CHILOQUIN 12 NW (FORT KLAMATH), OR US station, 17.8 miles from Klamath County, supplies the 7,365 HDD and 98 CDD this estimate runs on. Combined heating and cooling load puts Klamath County in the 79th percentile of this 3,162-county dataset. One local detail the R-value alone won't tell you: Klamath County sits in moisture regime B (dry), which can affect the vapor-barrier choice.

Already have some insulation?

Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $290/year saved — roughly 7.9 years to break even. Worth doing on the numbers alone.

Klamath 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.
