FAQs
OSB is not recommended for outdoor projects. OSB is considered an Exposure 1 panel, which means they may be used for applications where construction delays may be expected prior to providing protection. But OSB is not suitable for long-term exposure to the weather.
Yes, Georgia-Pacific plywood and OSB panels only use moisture resistant adhesives that contain no added urea formaldehyde resins, and are therefore exempt from U.S. EPA and California formaldehyde regulations due to their very low emission rates.
The number of panels in a unit of OSB varies depending on the type and thickness of product. On sheathing products, the piece count is typically stenciled on the side of the unit. Other products have corrugated side protectors that should indicate piece count. If you need a piece count and neither of those are visible, please contact GP at 800-284-5347.
No, span ratings for similar thicknesses are the same.
