Hi everyone, Im in the process of building my own studio but i found i have a problem, how should i attach 2 walls together with steel framing? I saw steves post about corner framing but only for wood studs, so i dont know if the corner shoud be closed up with mass (wood stud). any pic to show the direction? Thanks!
you don't need it mass-stuffed. The frames is not supposed to act as mass. It's just a means to hang sheets of gypsum (or whatever) on. Just make sure you attach the gypsum boards the "right" way and use sealant to cover the perimeter. There's plenty info on how to do corners. It you are not to confident, shift one of the metal studs about 1cm deeper so it gets a bit behind the other one. That way you'll be sure there's no gap and your sealant won't "escape" easily. However, you need to concern about enough grip for the layers of mass you're gonna hang there. You can always put two c-profile studs next to each other. no problem.

Ok so its simply for structural purpose the different ways for fastening the studs at the corner, it wasnt clear for me if it was for structural or acoustic purpose. Thanks!
A wooden framed wall adds mass due to the framing members. The difference between it (wood) and a metal framed wall is rigidity, a metal framed wall having less rigidity. The methods to frame either is simple. When you construct the assembly your goal is to accommodate the sheathing that will be applied directly to it. In the aspect of a double wall assembly, you construct the framing in respect to the sheathing as it will be applied to either the exterior face (if applicable) or the interior face of the wall assembly. As to if this is a discussion on ACOUSTICS or CONSTRUCTION...this is a discussion on CONSTRUCTION.
