Study Notes
Nonveneered Panels
- Nonveneered panels are engineered wood sheets created using resin, heat, and/or pressure.
- Types of nonveneered panels include oriented strand board (OSB), particleboard, and waferboard.
Oriented Strand Board (OSB)
- OSB comprises long, strand-like wood particles, glued and compressed into three to five layers.
- Strands in OSB layers are oriented in the same direction, enhancing strength and stiffness compared to waferboard and particleboard.
- Common applications of OSB include sheathing and subflooring in wooden-frame structures.
Particleboard
- Particleboard is not typically used for structural purposes, but it may serve in lateral-force-resisting diaphragms.
- It can be manufactured in large sheets, making it suitable for various applications.
- Often utilized in flooring for manufactured and mobile homes.
Manufacturing Process of Particleboard
- Made from wood particles bonded with synthetic resins through heat and pressure.
- Wood particle sizes can vary from 1 inch (25 mm) to very fine particles.
- Particleboard can be produced in single-layer or multilayer configurations.
- Maximum manufacturing dimensions for particleboard panels reach up to 8 by 40 feet (2.5 x 12 m).
