The main difference between moulded doors vs flush doors is their design and appearance. 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. Moulded doors are made from composite materials, or MDF, into specific designs, creating a textured and elegant look. These doors give the appearance of traditional wood doors with raised panels, but at an affordable cost.
