Treatment at exposed mullions
The system follows the vertical mullion line at the partition junction.
The Piedmont Plug treats the junction where interior partitions meet exposed curtain wall mullions to address unwanted sound transfer between rooms.

Glass curtain wall systems create a difficult acoustical condition when an interior partition terminates at an exposed mullion. A well-built wall can still lose privacy and acoustic performance at that final junction.
The Piedmont Plug is designed for the partition-to-mullion junction. Used with acoustical sealant at the partition-to-mullion gap, the system follows the mullion vertically and integrates into the finished space.

The system is installed continuously along the height of the mullion after the partition-to-mullion gaps are sealed. Product thickness and configuration are selected for the project condition, supported by measuring, installation and technical documentation.
