Been analyzing the interior wall thing to death. I finally decided to go with 3/4 T&G plywood. Chose to Tapcon the base angle rather than drive anchors. I'm doing it by myself so it's going slow.
Hello...I am going to do something similar to what you did in your building. I have a newer building that we built several years ago and in there I decided to stud it out for walls...the building is a partial garden shop for my wife and man cave for me. Especially in the man cave, I wanted to put up different walls (our projector wall is drywall, other walls are planked, etc.) so that is why I studded it out.
My older 30' x 50' building has been primarily used for storage. As I am typing this we have a spray foam contractor finishing up putting a thermal barrier on the foam and in the next several weeks I will begin putting up walls for what will eventually be a hobby wood/machine shop.
I am thinking of going straight to the framing with 3/4" T&G instead of studding out. I am wondering why instead of a base angle I couldn't use PT lumber with sinkers as a nailing board for the bottom of the plywood. i realize that steel would outlive what I have left on this earth but PT probably would also, especially if I paint it. Thanks for any advice.
BTW...what did you use as fasteners for attaching your boards? When I studded out my newer building I used these
