Panel for sheathing system and method
View Patent ↗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.
1. A panel for a panelized sheathing construction system comprising a wood or wood composite panel having a first inward facing surface, a second outward facing surface and a peripheral edge; said panel further comprising a panel surface barrier layer adhesively secured by a layer of adhesive to the outward facing surface of said panel, said panel surface barrier layer being substantially bulk water resistant; wherein said panel with said barrier layer is characterized by a permeability in a range from about 0.1 U.S. perms to about 1.0 U.S. perms as determined by ASTM E96 procedure A, a water vapor transmission rate from about 0.7 to about 7 grams/m 2 /24 hrs as determined by ASTM E96 procedure A (at 73° F.-50% RH), a permeability from about 0.1 to about 12 perms as determined ASTM E96 procedure B (at 73° F.-100% RH), and a liquid water transmission rate from about 1 to about 28 grams/100 in 2 /24 hrs via Cobb ring according to the test method described in ASTM D5795.
2. The panel of claim 1 , wherein said barrier layer further comprises an applied coating layer.
3. The panel of claim 2 , wherein said coating layer comprises an acrylic resin.
4. The panel of claim 2 , wherein said coating layer comprises an asphalt base.
5. The panel of claim 1 , wherein said surface barrier layer further comprises a UV resistant overlay.
6. The panel of claim 1 , further comprising a radiant reflective layer.
7. The panel of claim 1 , wherein a surface of said water resistant barrier layer is adapted to provide a wet coefficient of friction in a range of from about 0.8 to about 1.1 (English XL Tribometer) and said textured surface is adapted to provide a dry coefficient of friction of at least about 0.8 (English XL Tribometer).
8. The panel of claim 1 , wherein said surface barrier layer further comprises indicia for positioning fasteners, said fasteners being adapted to secure said panel on said building frame structure.
9. The panel of claim 8 , wherein said indicia further comprises alignment guides for applying strips of tape.
