Q. What are the differences between a paneled door and a flush door?

Traditional joinery doors often known as paneled doors have a lengthy history. They are made up of individual components - rails stiles and infill panels – that are put together to form the door. Flush doors are essentially a slab of material with a solid material core when performance doors are required. The solid cores are usually particleboard or laminated wood which may be covered with plywood or MDF sheets to provide a flat surface that can be painted veneered or laminated.
