combination core

Veneer core hardwood plywood is ideal for its strength and fastener holding properties. However, the rougher surface and varying densities of the plies can create an uneven surface and cause "telegraphing", as these imperfections are transferred through the face and back veneers. This telegraphing becomes visible when the panel is painted and finished and can detract from the appearance. Combination cores combine the strength of a veneer core panel with the smooth surface of a composite panel to eliminate telegraphing and allow for a much smoother finish.   

Combination cores are constructed with a thin layer of MDF just beneath the face and back veneers, creating a smooth, uniform substrate for the veneer to lay on without sacrificing strength or screw-holding ability. Adding MDF to the construction gives combination cores the added benefit of increased flatness and more stability over time; these layers of MDF do add weight, but not as much as an MDF core. The combination of strength, smoothness, flatness, and stability make combination core panels ideal for custom cabinetry, casework, and furniture applications where a high-quality surface and a clean finish are important.
