Oriented Strand Board

OSB PanelOSB shares many of the strength and performance characteristics of plywood.

Panels produced by APA member mills are manufactured to US Voluntary Product Standard PS2 – Performance Standard for Wood-based Structural-Use Panels, PS2-18. This sets the performance requirements based on the panels intended end use in load-bearing applications.

This performance approach is also taken by European Standards for wood-based panel products. See the individual European standards for OSB and the overall standard for wood-based panels, EN 13986: 2004+A1 2015.

The combination of wood and adhesives creates a strong, dimensionally stable panel that resists deflection, delamination, and warping.  Relative to their strength, OSB panels are light in weight and easy to handle and install.  They are able to resist racking and shape distortion when subjected to strong wind and seismic conditions.

APA-trademarked OSB can be used for a variety of structural uses including subflooring, single-layer flooring, walls and roof sheathing. The panel grade on the trademarked panel refers to the intended application, for example: Rated Sheathing, Rated Sturd-I-Floor.

These performance rated panels can also be used for non-building purposes as some of the performance requirements necessary for use in building are also applicable for use in industrial applications.
