- The core of flush doors might be solid, hollow, or stave. If the core is solid, low-density particle board or foam is frequently used to entirely cover the area within the door, and it may be reinforced on either side with a form of laminate or plywood.
- They’re great for outside doors since they add insulation and robustness.
- Wooden slats piled on top of one another form the core of a flush door with a stave core.
- Some support may be incorporated into the frame if the core is hollow.
- They have a simple design. The hardware will be recessed if the doors are to be set on tracks so that they may move past one another. A closet might benefit from this sort of design.
