How do you frame a wall more than 8-10 feet tall?
I see from your other question, that you are rehabing an industrial space. Personally, I'd use steel studs in this application. You can build them to 16 ft, no problem. You will need to install horizontal stiffeners as Mike mentions, unless you go wider that the 4 inches of wall thickness. It is very difficult to build and handle a wood framed wall of that size, but stacking is an alternative. Finding 2X4's that are not waned or bowed will be a challenge as well. 2X6's would be better, but steel would be the best.
