Panels should be stored flat, indoors or under cover and protected from the elements.
When stacking panels the blocking/supports must be aligned.
If units are stacked the blocking/supports also must be aligned.
If stored outdoors, keep panels off the ground and on a flat base. Cover loosely to allow air circulation at the sides.
OSB should not be exposed to the weather or moisture on a continuous basis. However, Exposure-1 exterior bond rating indicates that unprotected exposure during normal construction periods will not adversely affect the structural properties.
Panels should be handled and stored with care to avoid damage and should be used on a first-in, first-out basis.
