Doors can be classified as both internal and external.
External/ Exterior: The external or entrance doors are most commonly used for front/ rear entryways. These can be used in a single or double door configuration. When purchasing an exterior door, exterior door hardware should also be considered.
Internal / Interior: These doors are most commonly used for rooms inside the home and often vary in material as they are not exposed to the elements. Can be used in a single or double door configuration with suitable interior door hardware.
