More about: Door construction

Flush doors have flat surfaces. With this type of construction, the framing is concealed beneath a veneer surface. Inside may be a solid core of hardwood blocks or particleboard or hollow-core material such as corrugated cardboard. Flush exterior doors often have a core of solid foam. The face veneers are usually applied in two or more "cross band" layers-with the grain running perpendicular to each other to minimize warping.
