I am planning to hang a second layer of drywall along one side of an 18' hallway for soundproofing purposes (green glue between drywall layers) and I just want to make sure I am doing it correctly as it's my first time working with drywall.
The middle of the hall should be fairly straightforward but I have some concerns about the ends. Attached is a pic of one end of the hall wherein the stud (16" OC, marked with painter's tape) is behind a door frame. I know that, ideally, a sheet of drywall should be screwed onto studs at both ends but this is not possible in this case as the door frame is in the way.
I don't want to leave the sheet just hanging unscrewed on one side and and I'd greatly appreciate any suggestions.
Thanks for reading. -Reg
