Abstract
A composite structural board having a structural board and a water-resistant barrier (WRB) sheet, and a wall system comprising same, wherein a face of the structural board is discontinuously attached to the inner face of the WRB sheet solely by a first adhesive, the WRB sheet fully covering the face of the structural board; wherein the unattached areas between the face of the structural board and the inner face of the WRB sheet define paths by which a liquid can move between the face of the structural board and the inner face of the WRB sheet; in some instances the WRB sheet material extends beyond at least one edge of the structural board forming a WRB sheet flap.
