As I'm looking at purchasing a house in the next year or so I know I'll be finishing a basement, or remodeling an existing one for a dedicated room.\nFigured this could be an interesting thread will do's and dont's in the process.\nFor walls along the foundation, 2x3 or 2x4. Do you keep studs right up against the foundation or a few inches away, vapor barrier or no, if 2x3 studs do you space them every 16 or 24 inches. Rolled insulation, foam board, or other. Drywall thickness. The reason I bring these up is there is a long debate on 'the right way' especially pertaining to moisture.
