Product Description

15/32" OSB — 4×8 Sheathing Panels are loaded at our Boise, Idaho lumberyard for projects across the Treasure Valley. Engineered as a nominal 1/2" panel, these rigid APA-certified sheets carry a solid 32/16 span profile. This density gives them enhanced structural strength and stiffness under more demanding roof and wall loads.

Specifications
  • Thickness: 15/32" (Nominal 1/2")
  • APA Span Rating: 32/16
  • Moisture Class: Exposure 1
Common Uses
  • High-stiffness roof sheathing designed for wide 24" on-center truss configurations.
  • Heavy exterior wall backing and light commercial framing wraps.
Contractor & Builder Notes
  • Deflection Control: The heavy 32/16 structural code rating ensures minimal panel deflection or dip under construction framing foot traffic on open runs.
  • Pneumatic Prep: Set gun pressure flush; avoiding over-driven nail heads preserves the composite panel's full design pull-through strength values.
