Abstract
A sheathing panel includes a barrier overlay secured to a panel; wherein the sheathing panel is bulk water resistant and has at least one of the following properties: a water vapor transmission rate of at least 7.0 grams per square meter per 24 hours (grams/m2/24 hours) as determined by ASTM E96-15 procedure A at 73° F. and 50% relative humidity (RH), a water vapor permeance of at least 1.3 perms as determined by ASTM E96-15 procedure A at 73° F. and 50% relative humidity (RH), or an air infiltration rate of less than 0.2 liters per second per square meter (L/s-m2) at 75 pascals (Pa) as determined by ASTM E2357-11.
Claims22
A sheathing panel, comprising:
- a barrier overlay secured to a panel;
- and
- an anti-skid coating comprising a polymer and covering about 2 to about 25% of a surface area of the barrier overlay;
- wherein the sheathing panel is bulk water resistant and water vapor permeable.
A sheathing panel, comprising:
- a barrier overlay secured to a panel;
- and
- an anti-skid coating comprising a polymer, covering about 2 to about 25% of a surface area of the barrier overlay, including a repeating pattern, and providing a dry coefficient of friction of at least 0.6 as determined by ASTM F1679-04;
- wherein the sheathing panel is bulk water resistant and water vapor permeable.
A sheathing panel system, comprising:
- at least two adjacent panels, each panel having an outer surface, an inner surface, and at least one edge extending therebetween, wherein each panel is aligned with its at least one edge proximate to the at least one edge of the adjacent panel to define a longitudinal joint between the two adjacent panels, and wherein the edges of the adjacent panels are substantially parallel to each other;
- a barrier overlay secured to the outer surface or the inner surface of each panel;
- an anti-skid coating comprising a polymer and covering about 2 to about 25% of a surface area of the barrier overlay secured to the outer surface or the inner surface of each panel;
- and
- a means for sealing the longitudinal joint between the two adjacent panels;
- wherein each panel is bulk water resistant and water vapor permeable.
