The Importance of Mullions in Framing Systems

When choosing a framing system, aesthetics and functionality are important—but structural integrity should be a top priority. Frameworks Manufacturing explains the importance of mullions for structural integrity:

What Are Mullions?

A mullion is the vertical or horizontal element separating two window panes or doors. Mullions are used not only to enhance aesthetics but to divide glazing into smaller, more manageable units for easier installation and provide structural support for the framing system and its parts.

Popular Framing Systems Paired With Mullions 

Frameworks Manufacturing offers a wide range of aluminum framing options that accommodate mullions for greater structural integrity.

Our SlimLine series is an office front system designed to maximize light and space with minimal profiles. However, this system can be customized with corner posts or intermediate mullions to suit your needs.

The Serenity – STC-35, our sound control system, can accommodate sidelites with one horizontal or vertical mullion.

Our popular, highly functional sliding barn door system accommodates sidelite, horizontal, and vertical mullions.
