Roseburg’s Sheathing panels are especially designed for engineered applications such as structural components where design properties including tension, compression, shear, cross-panel flexural properties and nail holding and bearing are of significant importance. Sheathing is manufactured according to the grade, veneer and panel thickness, construction, workmanship, and identification requirements for plywood sheathing as outlined in the PS 1-09.


  • Custom grade, thickness, and dimensions available.
  • Produced to customer specifications to meet specific end use needs.
  • NAUF (No added urea formaldehyde)
  • All items available Structural 1


  • Nails directly over framing wall studs and roof joists.
  • Framing applications where state and/or local building codes require shear wall construction for extra strength.
  • Sub-wall/roof foundation for home wrap vapor-barrier and the most common siding material to be applied directly over it.


Can be cut, drilled, routed, glued, fastened and finished with ordinary tools. Always use sharp, high-speed tools. Because of the cross-layer construction, nails, screws, and other fasteners may be placed near the panel edge without splitting the panel.
