What is the best way to finish basement walls?
I'm putting in a 2 piece washroom in a finished basement. I've removed everything back to the foundation wall in that one area where I will be building. The basement was finished with tar paper on foundation wall, 2 by 2 framing with fiberglass insulation, vapour barrier and drywall. Everything I've researched including articles on this site suggest this is the wrong approach. I plan to glue 2" rigid to foundation wall, 2 by 4 framing with roxul and drywall. Is this best approach given the rest of basement is done the old school way (incorrectly)? Thanks in advance your site is new to me and is a great resource.
