What is the primary material composition of a flush door?

A flush door is primarily made from plywood and veneer. This composition gives the door a smooth, flat surface that is visually appealing and can fit well in various architectural styles. The plywood provides stability and strength, while the veneer adds a layer of aesthetic finish, allowing for a range of wood finishes and colors that can enhance the interior design of a space.

In contrast, solid wood doors are heavier and typically used for more decorative or structural purposes. Metal and glass options are seen in modern designs, but they serve different functional and aesthetic purposes than flush doors. Particleboard can be used in less expensive or lower-quality doors, but it lacks the durability and appearance that plywood and veneer offer in a flush design, making the latter the ideal choice for this type of door.
