A wall framing system for supporting an interior wall in spaced proximity to an exterior wall includes one or more stud members extending between upper and lower frame channel members, which are configured to self-locate in relation to the exterior wall in a manner which establishes a moisture and air barrier between the exterior wall and the interior wall supported by the wall framing system. The interior wall supported by the wall framing system is resistant to moisture degradation, and maintains desired R-value insulation properties throughout the wall.
