Unbranded Attic Pine Oriented Strand Board (Common: 5/8 in. x 2 ft. x 4 ft.; Actual: 0.594 in. x 23.75 in. x 47.75 in.)

OSB Attic Decking has a convenient tongue and groove design for easy installation. Use the tongue and groove feature to lock multiple boards together and improve the organization of your storage space. Enjoy a clean look and increase the usable square footage of your attic by multiples of 8 sq. ft. per board. For standard installation, apply this pre-cut decking to supporting joists or truss bottom chords spaced 24" O.C. or less. Securely fasten the decking to supporting members following the requirements of the local building code. Apply the long direction of the plywood across the supporting joist (the face grain of the plywood runs perpendicular to the supporting joist). When properly applied, this decking will support 30 pounds per square foot of storage load. See Fastening Requirements under Info & Guides for further installation instructions.
