Spray Foam Insulation in Augusta, GA

Spray Foam Insulation in Augusta covers a city founded in 1736 at the head of navigation on the Savannah River, on the fall line where the Piedmont meets the coastal plain. Wikipedia lists Augusta as Georgia's third-most-populous city, with 202,081 people at the 2020 census. After the Civil War, textile mills rose along the Augusta Canal, including Enterprise, Sibley and King mills, and the city grew outward from its historic core.

Heat and humidity

Wikipedia's climate summary describes very hot, humid summers: July averages 81.6F, 82 days a year reach 90F or more, and the record is 108F. Winters are short, with 53 freezing nights and occasional freezing rain; the record low is -1F. Cooling dominates energy use, so hot attics and humid crawl spaces are where most comfort problems start.

Older homes

Neighborhoods near downtown and along the canal hold older houses, some with raised floors over crawl spaces, tall ceilings and attics with little insulation. Crawl spaces under these homes are often vented, and batts under the floor tend to sag in humid air. Encapsulation or foam on the subfloor fixes that.

Newer homes

Farther out, ranches and two-story homes from the late 20th century onward usually have ducts in the attic and an attic floor with modest insulation. Sealing the ceiling and blowing loose fill deep, or foaming the roof deck to bring the ducts inside, are the two main options.

Code and programs

OpenEI lists Richmond County in Climate Zone 3A. The Insulation Institute's summary of Georgia's code lists R-38 ceilings for new work. Georgia Power's improvement program page lists incentives for bringing attics at R-38 or less up to R-49, plus air sealing through an affiliated installer.

Mill-era housing

Mill villages along the canal were built quickly for workers. Their small houses often have thin walls, little attic insulation and crawl spaces open to the weather. Small houses mean small jobs, and sealing plus attic loose fill makes a big difference in comfort.

Timing

Attics are easiest to work in during the cooler months, when temperatures up there are tolerable and foam and loose fill go in quickly. Crawl spaces and metal buildings can be done most of the year. Booking in fall or winter means the work is finished before the next cooling season starts.
