Lipscomb County, TX Insulation Payback
Lipscomb County attic insulation, by the numbers
Lipscomb County sits in IECC climate zone 4 (Mixed-Dry) — a wide swing between a hot dry summer and a cold winter. For a currently uninsulated attic, DOE and ENERGY STAR recommend building 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 $1,489 a year in heating and cooling — a payback around 2.3 years. Topping up the attic pays for itself fast here.
The breakdown behind the number
Split it out and it's roughly $1,240 a year on the heating side, $249 on cooling. By estimated insulation savings, Lipscomb County lands in the 52th percentile nationally. Zone 4 alone covers 825 counties in this dataset, and Lipscomb County comes in 192nd by savings. Texas averages $1,035/year across the counties tracked here; Lipscomb County comes in 44% higher.
The climate data behind this
The heating and cooling degree days behind this estimate — 4,639 HDD and 1,548 CDD (base 65°F, 1991-2020 normals) — come from LIPSCOMB, TX US, the nearest NOAA station with published normals, 3 miles from Lipscomb County's center. By total degree days, Lipscomb County sits at the 56th percentile nationally. One local detail the R-value alone won't tell you: Lipscomb 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 $217/year saved — roughly 10.5 years to break even. Call this borderline rather than a clear win.
Getting it done in Lipscomb County
Real bids depend on how easy the attic is to reach and whether old insulation needs removing first, so treat $3,480 as a starting estimate for a Lipscomb County job, not a quote. Expect at least a $600 minimum charge from most contractors.
Where these figures come from
Lipscomb 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.
