Insulation Needs in Marietta

Marietta’s housing stock spans multiple eras with very different original insulation standards. Homes built in the 1960s-1980s near Marietta Square and in established Cobb County neighborhoods often have original fiberglass batts rated R-11 to R-19 that have settled and compressed over decades. Newer construction in East Cobb — Walton, Wheeler, and Lassiter school district communities — may have builder-grade insulation that meets minimum code but falls short of optimal performance for Georgia’s climate.
