Door Mullions

Which Are the Two Main Types of Door Mullions?

The two main types of door mullions are:

• Fixed Mullions: These permanently installed mullions provide structural support and a decorative element. They are ideal for larger openings or when removability isn't necessary.
• Removable Mullions: Designed for easy removal, these mullions offer flexibility for wider access when needed. They are commonly found in commercial settings for moving large objects.

Features of Door Mullions

The following are some of the features offered by commercial door mullions:

• Structural support: Mullions provide structural support for large or heavy doors, helping to prevent them from sagging or warping over time. This is especially important for doors that are made of glass or other fragile materials.
• Increased security: By dividing a doorway into two smaller openings, mullions can make it more difficult for intruders to break in.
• Energy efficiency: Mullions can help improve the energy efficiency of a doorway by creating a thermal break between the inside and outside of the building.
• Design versatility: Mullions can be used to create a variety of different designs, dogging options (less dogging), door heights (7ft and 8ft), and finishes (Primed USP-600 and Stainless Steel).
• Increased light: Mullions with glass can allow more light to pass through a doorway, brightening up the space on either side.

Apart from the above, door mullions can also be used to accommodate a variety of hardware options, such as locks, handles, and knockers.
