Frequently Asked Questions

Will Osb Absorb Water?

Yes, OSB will absorb water. It is a natural property of the material to absorb moisture from the air. This can cause the material to swell, which can affect its strength and stability.

Will Wet Osb Dry Out?

The answer to this question depends on a few factors, including the relative humidity of the surrounding air and the thickness of the OSB. In general, if the relative humidity is high and/or the OSB is thick, it will take longer for the OSB to dry out. If the relative humidity is low and/or the OSB is thin, it will likely dry out more quickly.

Is It Ok For Osb To Get Rained On?

Yes, it is OK for OSB to get rained on. However, if it is going to rain for an extended period of time, it is best to cover the OSB with a tarp or some other type of waterproof material.


While it is possible for OSB sheathing to get wet, it is not ideal. The best way to avoid this is to make sure that the sheathing is properly installed and sealed.
