Fiberglass Batting
(R-11 to R-38) Fiberglass batting insulation is used for exterior walls, interior walls, and ceiling batts. Air-Tite uses Owens corning fiberglass batts, which meet all building codes and can vary in r-values depending on the application type. These batts are used for not only energy efficiency, but also for sound proofing interior walls of a home as well.
