How Thick Is A Sheet Of OSB For Wall Sheathing?
OSB, or oriented strand board, is a type of engineered wood panel that is often used for wall sheathing. It is made from wood strands that are oriented in a specific direction and then bonded together with resin. OSB is a strong and durable material that is also relatively inexpensive, making it a popular choice for construction.
The thickness of OSB for wall sheathing is typically 7/16 inch, although other thicknesses are also available. The thickness of the OSB will depend on the specific application and the requirements of the building code. For example, in areas where there is a high risk of hurricanes or earthquakes, thicker OSB may be required.
Factors to Consider When Choosing OSB Thickness
When choosing the thickness of OSB for wall sheathing, there are several factors to consider, including:
- The type of construction: OSB is used in both residential and commercial construction. In residential construction, OSB is typically used for wall sheathing, roof sheathing, and subflooring. In commercial construction, OSB is often used for wall sheathing, roof sheathing, and floor underlayment.
- The climate: The climate in which the building is located will also affect the thickness of OSB that is required. In areas with high winds or heavy snow loads, thicker OSB may be required.
- The building code: The building code will specify the minimum thickness of OSB that is required for wall sheathing. This thickness will vary depending on the location of the building and the type of construction.
Advantages of Using OSB for Wall Sheathing
There are several advantages to using OSB for wall sheathing, including:
- Strength: OSB is a strong and durable material that is able to withstand high winds and heavy snow loads.

- Ease of installation: OSB is easy to install, making it a good choice for do-it-yourselfers.
Disadvantages of Using OSB for Wall Sheathing
There are also some disadvantages to using OSB for wall sheathing, including:
- Weight: OSB is a heavy material, which can make it difficult to transport and install.
- Off-gassing: OSB can off-gas chemicals, which can be harmful to indoor air quality. This is especially a concern for people with asthma or other respiratory problems.
