Panel for sheathing system and method
The panel includes a water resistant barrier layer secured atop its outward facing surface. The water resistant barrier layer includes a skid resistant surface. The panels are made of lignocellulosic material. The water resistant and skid resistant surface may include indicia for aligning strips of tape or for aligning fasteners. A method for manufacturing the water resistant building panels is also disclosed and includes the steps of feeding paper onto a forming belt, depositing lignocellulosic material and the binding agent onto the forming belt so as to form a lignocellulosic mat, applying heat and pressure so as to impart the skid resistant surface on the paper, and cutting panels to predetermined sizes.
