The mullion width is the dimension between the center of each mullion. The mullion height is the dimension between the top and bottom of the mullion.
What are Mullions?
Mullions are vertical dividers that separate windows or doors. They can be fixed, or they can be operable. Operable mullions are often used in commercial applications to allow for opening and closing of windows to allow for changing weather conditions.
What are Mullions Used For?
Mullions are used to divide a window into smaller sections, allowing you to create more than one window on a single wall. They can also be used to divide a door into smaller sections, allowing you to create multiple doors in one doorway. The amount of space between the mullions depends on what style you want your home’s exterior to take on.
If you want a more modern look, then you may consider using smaller sections of space between each mullion section; however, if you prefer a more traditional look, then using larger sections will give your home an old-fashioned appearance while still providing ample privacy between each section.
