Oriented strand board

(OSB)
A high-strength, structural wood panel formed by binding wood strands with resin in opposing directions. OSB is beneficial in that it uses small-dimension and waste wood for its fiber; however, resin type should be considered for human health impact, and the production process monitored for air-pollutant emissions.
