What is Particle Board?

Particle board is a popular, albeit less durable, alternative to solid wood. If you've ever been curious about this unique material's design and function, read on to learn more.


Particle board is primarily comprised of the sawdust produced by industrial saw mills and other types of wood processing businesses. The sawdust is held together with a powerful resin and subsequently hardened and pressed into long sheets by an extrusion machine. The sheets are then cut into smaller sizes to accommodate the home improvement tasks for which they will be used.

Common Uses

Particle board is commonly used for home improvement projects that don't require a great amount of durability. This building material is popular for constructing bookcases and shelving for home theater systems. Additionally, it can be utilized to create sub-flooring, but given its susceptiblity to moisture, this is generally not recommended. 


While particle board is less expensive than solid wood, it is not nearly as resilient. For example, it is extremely weak against moisture. Prolonged exposure to moisture will not only stain and warp particle board, it will dramatically weaken it as well. For this reason, it is recommended that you abstain from using particle board for any outdoor projects.
