Rated Sheathing: Walls

Rated Sheathing 9.5mm Panel: Bending Strength & Stiffness with Support Spacing Options 

General info: APA rated OSB Sheathing always has a bond durability classification of Exposure 1 as not for exterior use. Panels have one surface with an overlay, texturing or grooving. Creating the tongue reduces the panel width by approximately 12.5 mm (1/2”), so net width may be 1,206mm (47.5 in)
Bending strength – stress applied parallel: Factor of safety (F S) – 300 (lb-in²/ft of panel width) when stress applied parallel to strength axis. The strength axis is always parallel to the face and back orientation of the strands unless otherwise indicated
Bending strength  – stress applied perpendicular: Factor of safety (F S) – 97 (lb-in²/ft of panel width) when stress applied perpendicular  to strength axis
Bending stiffness – stress applied parallel: E I (lb-in²/ft of panel width) -60,000 when stress applied parallel to strength axis. E I provides a measure of the resistance of the beam to bending. The larger the E I, the smaller the deflection
Bending stiffness – stress applied perpendicular: E I (lb-in²/ft of panel width) – 11,000 when stress applied perpendicular to strength axis
Span rating/support spacing: Wall-16 or Wall-24 oc
Thickness/ US Performance Category: 9.5mm (min 8.7mm; max 10.3mm); (3/8)*
