This product meets APA Performance standard structural tests and engineered to perform in applications that require superior cross-panel strength, racking strength or shear resistance. Roof sheathing Select the appropriate Technowood Engineered osb panel thickness or span rating for tne Apply the strength axis perpendicular to the supports. All panels should be continuous over two or more spans; all end joints must be staggered Fasteners shall be located a minimum 3/8" from panel edges. Leave 1/8" gap at all panel ends and edges to allow movement due to climatic changes, preventing roof panel ridging.
