ABSTRACT:
A wall assembly includes a wall frame, a trough, a moisture transport spacer coupled to the wall frame and providing a substantial barrier to the passage of air and moisture vapor through the wall assembly, a moisture wicking sheet disposed at a bottom of the wall frame and extending from the moisture transport spacer to the trough, and an air seal disposed between the moisture wicking sheet and the bottom of the wall frame. The trough communicates with a dynamic ventilation system configured to remove moisture collected in the trough.
