Spray Foam Insulation in Thomasville, GA

Spray Foam Insulation in Thomasville serves Thomas County's seat, about 34 miles northeast of Tallahassee. Thomasville was founded in 1825, incorporated as a town in 1831 and as a city in 1889, and is known as the City of Roses for its yearly Rose Festival, according to Wikipedia. Its Big Oak, a southern live oak, dates to about 1680. The 2020 census counted 18,881 residents and 8,874 housing units, 11.6% vacant.

Older homes downtown, newer ones outside

Thomasville has a historic downtown with older houses, plus newer homes. Older homes tend to have tall ceilings, chimneys and floors over crawl spaces, with attics that hold little insulation. Newer homes usually have blown insulation in the attic but leaks around lights, fans and the hatch. In both, sealing the attic and bringing it to depth is the first step.

Plantation land and outbuildings

The area is known for plantations open to the public, including Pebble Hill Plantation. On rural properties with barns, equipment sheds and metal shops, closed-cell spray foam on steel stops condensation and heat, and in wood barns it can insulate the part you plan to use as a shop or office.

Climate

Wikipedia's climate figures for Thomasville list an annual mean daily high of 79F, an annual mean low of 56F, 53.3 inches of rain a year, a record high of 106F and a record low of 5F. Summers are long and humid, and winter cold snaps are sharper than on the coast. A house sealed at the attic and floor stays more comfortable in both seasons.

Climate zone and Georgia code

Thomas County is in IECC Climate Zone 2A, the same hot-humid zone as Tallahassee (OpenEI). Georgia adopts its own version of the energy code, so check current requirements with the city or county building office for any remodel. For existing homes, DOE's Zone 2 guidance suggests R-49 to R-60 for an attic starting from nothing and adding R-38 to R-49 where 3 to 4 inches already exist.

Historic houses, careful work

In older Thomasville houses, we look closely at chimneys, old wiring and any vermiculite before we cover anything, and we plan the floor so moisture is not trapped against old wood. Attics are usually the simplest place to start: seal, then insulate to depth. Where there is a finished attic room or a cathedral ceiling, spray foam under the roof deck is often the only practical way to insulate it.
