Spray Foam Insulation in Texarkana, AR

Spray Foam Insulation in Texarkana, Arkansas starts with a different code than across the street. The Miller County seat was organized on December 8, 1873, and incorporated in Arkansas in 1880. The 2020 census counted 29,387 residents and 13,593 housing units, 13.0 percent vacant. The city sits in the Piney Woods on the flat Gulf Coastal Plain, with Nix Creek draining to the Red River.

Climate

Texarkana Webb Field's 1991-2020 normals list a July average high of 92.7F, a January average low of 35.1F, about 48.87 inches of precipitation and 2.7 inches of snow a year. Records run from 117F in August to -9F. Humid summers dominate, but cold snaps happen.

Arkansas code

Arkansas uses the 2009 IECC with state amendments, in effect since January 1, 2015. In Climate Zone 3, which includes Miller County, it lists R-30 for ceilings, R-13 for wood-frame walls, and R-13 cavity or R-5 continuous for crawl space walls. Those are minimums for new work; ENERGY STAR suggests R-49 for an existing attic with no insulation.

Housing

The Arkansas side has older homes near downtown, postwar homes and newer neighborhoods. Crawl spaces are common, and in a city this humid, those crawl spaces are often where comfort problems start. Sagging batts, sweating ducts and damp framing are the usual findings.

The courthouse on the line

The Federal Courthouse sits directly on the Arkansas-Texas line and is described as the only federal office building to straddle a state line. For homeowners the line matters too: the energy code, permit office and utility programs differ by side.

Utility help

If SWEPCO is your utility, its weatherization page lists insulation and caulking and weatherstripping through approved Arkansas contractors. Check the current program first.

Red River Army Depot

The Arkansas side's 2018 financial report lists the Red River Army Depot as the largest single employer, with 4,135 employees. Homes from the decades after World War II, when the depot was growing, often have crawl spaces with failing insulation and attics that need sealing.

Sulphur River bottoms

The Sulphur River Wildlife Management Area preserves 16,520 acres of bottomland hardwoods, cypress breaks and oxbow lakes in Miller County. Bottomland and frequent rain keep the ground damp, which is why crawl spaces here so often need work.
