Abstract
The present invention provides a panel sheathing for making wall and roof structures in which the panels (e.g., wood boards, oriented strand boards, plywood, etc.) are pre-coated at a factory, before installation at the building/construction site, using a polymeric barrier coating having specific water permeability, self-sealing properties with respect to penetrated metal fasteners (e.g., nails) in accordance with ASTM D7349 (modified using 1.5-5.0 inches water depth in hydrostatic head testing over sample of coated panel in which a steel nail is driven to within ⅛ inches of being flush with the panel and conditioning the test specimen for 24 hours at 23° C. prior to hydrostatic loading), as well as anti-blocking properties whereby the coated panels can be transported in stacked configuration without sticking or disintegration of the polymeric barrier coating. The coated panels do not require the use at the installation site of felt paper, house wrap, or additional applied barrier coating to provide excellent weather barrier properties. The present invention also provides methods for constructing the panel sheathing structure as well as for making the coated panels.
