OSB can be easily identified by its visible wood strands.

Oriented strand board, commonly called OSB, is a type of particle board which is made of carefully positioned strands of wood. Aspen and other similar woods are cut into long strands parallel to the grain of the wood.[1] It is manufactured into sheets made up of wood strands, wax, and resin adhesives. Sheets are formed under pressure and heat.[1] The finished sheet size varies by country. OSB is very strong making it ideal for building construction.[1] Its most common uses in construction are for covering walls, floors and roofs before the finish products are applied.

  • OSB-2 is specially designed OSB for load-bearing purposes. It is for use in dry areas.[2]
  • OSB-3 is designed the same, but is for use in wet areas.[2]

OSB can also be made from trees from areas burned over by forest fires.[3]
