Crittenden County, AR Insulation Payback
Crittenden County, AR: what topping up your attic actually costs
Crittenden County sits in IECC climate zone 3 (Mixed-Humid) — a genuine mix of cold winters and humid summers, with neither one dominating the bill. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to R-49. For an attic around 1,000 square feet, closing the gap from R-2 to R-49 costs around $2,820 and saves an estimated $1,143 a year — payback in roughly 2.5 years. That's about as fast as attic paybacks get.
Where the savings come from
The estimated savings split roughly $797/year heating, $346/year cooling. Out of every 100 US counties tracked here, Crittenden County's savings potential beats roughly 27 of them. Within zone 3 specifically, it ranks 171st of 690 counties by estimated savings. Arkansas averages $1,185/year across the counties tracked here; Crittenden County comes in 4% lower.
The climate data behind this
Crittenden County's climate figures — 3,004 heating and 2,173 cooling degree days a year — are read from WEST MEMPHIS MUNI AP, AR US, 5.9 miles away, NOAA's nearest 1991-2020 normals station. Combined heating and cooling load puts Crittenden County in the 31th percentile of this 3,162-county dataset. Crittenden County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
If the attic isn't bare
A shallower starting point changes the math: with R-11 already down, only the gap to R-38 needs filling, at roughly $1,620 for an estimated $154/year saved (~10.5-year payback). This one is a genuine toss-up, not a clear yes.
Next steps for a Crittenden County attic
Actual quotes will vary by attic access, existing debris, and whether the job needs air sealing first. Treat the $2,820 figure above as a planning number for Crittenden County, not a bid - contractors typically charge a $600 minimum regardless of job size.
Nothing here is a guess
Every figure on this page traces to DOE/IECC climate zones and NOAA degree-day normals, documented in the methodology guide. The guide to what R-value actually means explains why R-49 is the target here specifically.
