Glasscock County, TX Insulation Payback
Is attic insulation worth it in Glasscock County, TX?
Glasscock County sits in IECC climate zone 3 (Hot-Dry) — intense summer heat with low humidity, where attic radiant heat gain is the main driver. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to R-49. Going from R-2 to the recommended R-49 costs roughly $2,820 installed for a typical attic (about 1,000 sq ft), and pays for itself in about 2.6 years at an estimated $1,092/year saved. Few home upgrades pay back that quickly.
Heating vs. cooling in Glasscock County
Heating accounts for about $743/year of that and cooling about $349/year — Glasscock County needs both. Nationally, Glasscock County ranks in the 24th percentile for insulation savings potential. Compared only against its own climate zone, Glasscock County places 253rd out of 690. Against Texas's own average of $1,035/year, Glasscock County runs 6% above that.
Glasscock County's actual weather, not a national average
NOAA's GARDEN CITY, TX US station, 2.4 miles from Glasscock County, supplies the 2,801 HDD and 2,188 CDD this estimate runs on. Combined heating and cooling load puts Glasscock County in the 25th percentile of this 3,162-county dataset. Its moisture regime is classified dry, 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 Glasscock County's attic already has 3-4 inches of old insulation (about R-11) rather than bare joists, the recommended target drops to R-38. That smaller top-up costs around $1,620 and saves an estimated $147/year — payback about 11 years. Whether that is worth it depends on how long you plan to stay.
Getting it done in Glasscock County
Real bids depend on how easy the attic is to reach and whether old insulation needs removing first, so treat $2,820 as a starting estimate for a Glasscock County job, not a quote. Expect at least a $600 minimum charge from most contractors.
