In LEED v4.1 they've changed to a wall panels category which focuses mostly on finish wall treatments. Does this category include gypsum sheathing? Or does it exclude internal wall components? We are having a difficult time finding sheathing products that meet Greenguard Gold. It is unclear to me if sheathing is included in v4.1 . Our sheathing is within the waterproofing membrane.  Any clarity would be appreciated. Thank you!
