| Particleboard Core (PBC)An inexpensive composite core consisting of pressed, resin-bonded wood particles. Surfaces are consistently flat and void-free. Panels are dimensionally stable, but heavier than solid wood, susceptible to moisture, and weak at the edges with a tendency to splinter. |  |
| Medium Density Fiberboard (MDF)A fairly inexpensive composite core made of finely ground wood fibers pressed together with resin binders. MDF is denser, stronger, and more resistant to tearing than particleboard, meaning that it can be milled and shaped. Its consistency and smoothness are ideal for veneer application. |  |
| Veneer CoreA lightweight substrate comprising innerplies of western softwood veneers. Dimensionally stable with excellent screw holding capabilities. Increased potential for core transfer / telegraphing with thinner face veneers. More significant thickness variations than typically seen with composite cores. |  |
| Hardwood X-Band Veneer CoreWestern softwood innerplies are supplemented with poplar veneer crossbands, making for a much smoother, and more ideal veneer application surface. This results in a lightweight, durable panel with excellent screw holding capacity, and a reduced propensity for core transfer. |  |
| MDF X-Band Veneer CoreWestern softwood innerplies are supplemented with MDF crossbands, providing an exceptionally smooth surface, suitable for high-end face veneers. Heavier than veneer core panels, but more lightweight than full MDF cores, and with substantially better screw holding capacity. |  |
| Birch MultiplyA high-end, nearly void-free core made from birch veneer innerplies. Thanks to its uniform hardwood construction, it machines consistently, holds screws exceptionally well, and is suitable for an exposed-edge finish. |  |
