Roof Sheathing Installation*

  • Install Norbord OSB panels with long sides running perpendicular to rafters or top chord members
  • Leave a gap of approximately 3mm between panel edges to allow for expansion due to rain or increased humidity
  • Blocking can be eliminated when using OSB panels featuring a tongue & groove (T&G) joint, resulting in faster installation
  • Recommended OSB grade class: 3
  • For detailed inquiries about OSB structural strength properties and other technical points please contact our sales and marketing staff at Interex Japan.
