Pre Treated Wood or XPS or FoamSeal
I am about 95% complete with insulating my concrete walls with XPS. I was able to glue them but I spent alot of time smoothing out the walls with my Fatmax chisel. Anyway, my next step is framing! My question now is what is the best method for protecting the base wood from rotting? Do I use XPS, or the Owens Corning Foam Seal, or pre treated wood? Ideally I would want the most cost conscious choice however if one is really better than the other I would probably go that route.
