Structural 1 Rated Sheathing: Floors

Structural 1 Panel (18.2mm) – Bending Strength & Stiffness with Support Spacing ‘Floor-24’  

General info: Structural 1 denotes a performance-rated panel, with superior bending stiffness and strength
Bending strength – stress applied parallel: Factor of safety (F S) – 1,000 (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) – 607.5 (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) – 400,000 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 – 146,600 when stress applied perpendicular to strength axis
Span rating/support spacing: Floor-24
Thickness/US Performance Category*: 18.2mm (min 17.48mm; max 19mm); (23/32)*
