There are 3 methods that are acceptable ways to install Owens Corning fiberglass insulation. Friction fit, Face Stapling and Inset Stapling are all equally as effective pertaining to a vapor retarder standpoint. Once the drywall/gypsum board (air barrier) is installed over the insulation, the minimal exposure of the studs, when friction fit or inset stapling, is not a significant difference. It's basically the preference of the installer. One reason that many installers probably install with friction fit is if face stapled, and there are any staples that aren't inserted well enough, it could cause issues when it comes to installing the drywall.
