Q: How is MDF made?
A: Medium Density Fiberboard (MDF) is a wood fiber composite panel consisting of recycled wood particles that are softened in steam vats called digesters. The softened particles are refined to individual fibers, dried, mixed with resin, and formed into mats. The mats enter a heated press and are cured, becoming panels. Panels are then typically sanded, graded and cut to the appropriate size.
Q: How is particleboard made?
A: The process of manufacturing particleboard is very similar to that of manufacturing MDF, however the recycled wood particles are not softened and refined. Rather, the wood particles are milled to sizes appropriate for the face or core of the panels before introducing the resin and forming into mats.

Q: What is CARB?
