23/32" OSB APA-rated tongue-and-groove subfloor (4×8) — commonly referred to as 3/4" OSB subfloor — is a heavy-duty structural panel designed specifically for residential floor systems.
The tongue-and-groove edge profile provides panel-to-panel load transfer, reducing floor deflection and helping eliminate edge movement and squeaks when installed correctly.
This thickness is commonly specified over floor joists and I-joists in single-family and light multi-family construction.
