Veneer core hardwood plywood is first choice for many applications. Hardwood plywood 1/2” or less is usually specified with veneer core. However, thicknesses range from 1/8” to 3/4”. All plies are less than 1/4”, ranging in odd numbers from 3 to 7 (depending upon thickness). Veneers are bonded with water-resistant resin adhesives. |

Lumber Core plywood is most often found in the construction of import panels, usually only 18mm thickness panels. Lumber Core plywood consists of a face & back veneer, then a layer of crossband veneer, with the edge glued lumber in the center. Lumber Core plywood should be used for the bending strength and screw-hold ability. |

Medium Density Fiberboard Core has the most uniform thickness and consistency of any panel core. The face and back veneer are glued directly to the MDF Core without the need for a crossband veneer. |
 |
Particleboard Core panels are constructed similar to MDF Core panels, with the face & back veneers glued directly to the core. Particleboard Core lays flat like MDF, but does not have the screw-hold strength of other cores. Particleboard Core is the least expensive of all core types. |
