As the name suggests, single leaf doors have a single door panel that opens. They are the most common type of door found in residential homes. Single leaf doors are also popular in commercial and industrial applications, particularly in smaller openings.
While single leaf doors are made up of a single door leaf or panel that opens and closes, double doors have two panels that open in the middle, giving you a wider opening. These two panels are sometimes separated by a mullion.
Double doors may feature door leaves that are equal in width (called an equal pair) or different widths (called an unequal pair). Double leaf doors are common in larger commercial and industrial applications.
