Medium-density fiberboard
Flush doors have a simple, flat surface characterized by their sleek and minimalist look. These doors are made from materials such as wood, medium-density fiberboard (MDF), or veneer. They are particularly popular for spaces where a clean appearance is desired.
A door is a hinged or otherwise movable barrier that allows ingress (entry) into and egress (exit) from an enclosure. The created opening in the wall is a doorway or portal. A door's essential and primary purpose is to provide security by controlling access to the doorway (portal).
