Matagorda County, TX Insulation Payback
Is attic insulation worth it in Matagorda County, TX?
Matagorda County sits in IECC climate zone 2 (Hot-Humid) — long, muggy summers and mild winters, where cooling dominates the energy bill. 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 3.5 years at an estimated $799/year saved. That is a solid payback as home upgrades go.
Heating vs. cooling in Matagorda County
Heating accounts for about $350/year of that and cooling about $449/year — Matagorda County needs both. Nationally, Matagorda County ranks in the 4th percentile for insulation savings potential. Compared only against its own climate zone, Matagorda County places 177th out of 233. Against Texas's own average of $1,035/year, Matagorda County runs 23% below that.
Matagorda County's actual weather, not a national average
Matagorda County's climate figures — 1,319 heating and 2,820 cooling degree days a year — are read from MATAGORDA NO 2, TX US, 6.5 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Matagorda County sits at the 4th percentile nationally. 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.
Already have some insulation?
Already have a few inches up there? Topping R-11 up to R-38 runs about $1,620 for about $108/year saved — roughly 15 years to break even. Whether that is worth it depends on how long you plan to stay.
