Abstract

A sheathing panel including a cementitious substrate having a first side and a second side. The first side faces an interior of a building and the second side faces towards an exterior of the building. The sheathing panel includes a moisture-resistant fabric having a first surface and a second surface opposing the first surface. The first surface is joined with the second side of the cementitious substrate and the second surface faces an exterior. The moisture-resistant fabric includes an adhesive layer disposed on the first surface.
