What is the minimum thickness that OSB (Oriented Strand Board) typically comes in?

The minimum thickness that Oriented Strand Board (OSB) typically comes in is 3/8 inch. This thickness is commonly used in various construction applications, including sheathing for walls, roofs, and floors. OSB is designed as a structural panel, and at this thickness, it provides an adequate level of strength and support required for most building projects.

While thinner panels like 1/4 inch do exist, they are not standard for load-bearing purposes and are generally used for specific non-structural applications. Similarly, options like 1/2 inch and 5/8 inch are thicker than the minimum required standard, often utilized in applications where additional strength and load-bearing capacity are necessary. Thus, 3/8 inch is widely accepted as the minimum thickness for OSB products used in general construction.
