Fire Inspection and Code Enforcement Practice Test

Oriented Strand Board (OSB) is the wooden structural panel formed by gluing and compressing wood strands under heat and pressure. In manufacturing, long wood strands are aligned in layers and bonded with resin adhesives, then pressed together to create a strong, uniform panel. The layered strands are oriented to provide strength in multiple directions, making OSB a common choice for structural sheathing in walls, floors, and roofs. It’s typically more cost-effective and provides good stiffness and shear resistance compared to some other options. The other terms refer to concepts like fire performance, emergency exits, or occupancy type, so they don’t describe a wood panel made from glued and compressed strands.
