Can you use OSB 3 board flooring?
OSB3 with Tongue and Groove profiling is versatile, BBA approved and water-resistant timber panel suitable for load-bearing roofing and flooring applications in dry and humid conditions.
How long will OSB board last outside?
How Long Will OSB Last Outside? Oriented strand board will commonly withstand 3 to 6 weeks of exposure on a construction site without issue. EXPOSURE 1 panels have a waterproof bond and often experience unprotected exposure for six months on building sites.
Will OSB get ruined if rained on?
Our OSB is rated “Exposure 1” and that means that it will withstand normal delays in construction. Normal delays and the rain you indicated will not affect the structural properties of the panels. Certainly it would have been better to have covered the roof with a tarp or roofing felt before it rained.
Is OSB board suitable for outside?
OSB can be used for outside applications. However, those OSB boards are classified as class 3 and they are appropriate for use in humid conditions.

Does OSB board warp?
OSB is built by pressing smallers strands of wood together with glue and wax in a hot press. OSB looks a lot like a collage of different wood chips. Unlike it’s plywood counterpart, OSB lacks the forces that tend the wood to warp, and so is easier to get perfect dimensions and avoid warping tendencies.
