When planning a school auditorium partition stacking pocket acoustic panel system, the stacking pocket is where the movable wall disappears when not in use. For architects and facility planners, this recessed area is more than a storage niche—it is a critical component that affects acoustic integrity, operational ease, and the long-term flexibility of the space. Whether you are designing a new performing arts center or renovating an existing auditorium, understanding how stacking pockets work with wall-mounted acoustic panel edges is essential for achieving a professional result.
Understanding the Role of Stacking Pockets in Movable Partitions
A stacking pocket is a recess in the wall or ceiling that receives the movable partition panels when they are retracted. Unlike a simple wall opening, a well-designed stacking pocket allows the panels to park neatly, flush with the surrounding architecture, without interfering with the floor space. For school auditoriums, this is particularly important because the same room may serve as a large assembly hall or be subdivided into smaller classrooms or rehearsal spaces.
The key characteristic of an EBUNGE movable partition is that each panel is individually movable and suspended from a top track. This design means the panels cross the opening without a floor track, which is a major advantage for accessibility and ease of cleaning. The panels are guided along a top track and can follow straight, turning, or stacking routes, depending on the layout. The stacking pocket must be planned to accommodate these routes, ensuring that panels stack parallel to each other in a compact, organized manner.
Why Stacking Pockets Matter for Acoustic Performance
While the panels themselves are designed to provide sound separation, the stacking pocket is a potential weak point. If the pocket is not properly integrated with the wall-mounted acoustic panel edges, sound can flank around the partition, reducing the overall acoustic effectiveness. Therefore, the design of the stacking pocket must consider the sealing of the opening when the partition is in use, as well as the acoustic treatment of the pocket surfaces.

Key Considerations for School Auditorium Layouts
Every school auditorium has unique dimensions, sightlines, and usage patterns. When planning a movable partition with stacking pockets, the first step is to review the layout to determine the most practical stacking position. This involves considering where the panels will be stored when the full space is needed, and how that storage location affects the usable floor area.
Straight, Turning, and Stacking Routes
Movable partitions can operate along straight routes, turn corners, or stack into a designated area. For a school auditorium, the stacking pocket is often located at one end of the room, behind a wall or column. The route from the open position to the stacking position must be clear of obstructions such as lighting fixtures, sprinklers, or ductwork. It is essential to plan these routes early in the design process to avoid conflicts.
Stacking Pocket Dimensions and Clearances
The dimensions of the stacking pocket must accommodate the number of panels and their thickness. The depth of the pocket should allow the panels to be fully recessed, with enough clearance for the top track and any edge seals. The width should be sufficient for the panels to stack side by side without rubbing against each other. A common mistake is to make the pocket too shallow, forcing the panels to protrude into the room, which can be unsightly and reduce acoustic performance.
Wall-Mounted Acoustic Panel Edges
When panels stack against a wall, the edge of the panel that meets the wall must be designed to provide an acoustic seal. This is often achieved with a wall-mounted acoustic panel edge, which is a gasket or seal attached to the wall that compresses against the panel when it is in place. The wall-mounted edge ensures that sound does not leak through the gap between the panel and the wall. In the stacking pocket, the same type of edge may be used to seal the panels when they are in the stored position, preventing sound from passing through the pocket into adjacent spaces.
Acoustic Sealing and Flanking Paths
Acoustic performance of movable partitions is often described using sound transmission class (STC) or weighted sound reduction index (Rw). These ratings indicate how much sound is reduced when passing through a partition. However, the actual performance depends on the entire system, including the walls, floor, ceiling, and any gaps or penetrations. Flanking paths are routes that sound can take around the partition, such as through the stacking pocket, ductwork, or ceiling plenum. To achieve the desired acoustic separation, all flanking paths must be addressed.
Sealing the Stacking Pocket
The stacking pocket itself must be sealed when the partition is in use. This can be done with a series of seals that are activated when the panels are deployed. The seals may be located at the top, bottom, and vertical edges of the panels, as well as at the interface between the panel and the pocket. The design of the pocket should allow for these seals to be easily maintained and replaced if needed.
Integrating Wall-Mounted Edges with Pocket Design
Wall-mounted acoustic panel edges can be installed inside the stacking pocket to provide a seal when the panels are stored. This is particularly important if the auditorium is used for performances while the partition is retracted, as sound from the stage could travel through the pocket into backstage areas. By incorporating a wall-mounted edge, the pocket becomes an acoustically sealed enclosure, minimizing sound leakage.
Pass-Door Requirements in Auditorium Partitions
Many auditorium partitions include a pass-door to allow movement between spaces without deploying the entire partition. When planning a stacking pocket, the location of the pass-door must be considered. The door should be positioned so that it does not interfere with the stacking of the panels. In some cases, the pass-door may be integrated into one of the panels, which adds complexity to the stacking sequence. It is important to discuss pass-door requirements with the partition manufacturer to ensure that the stacking pocket accommodates the door swing and hardware.

Finish Options for Auditorium Partitions
The visual appearance of the partition is important in a school auditorium, where the wall may be visible during performances or events. EBUNGE offers a range of finish options, including laminate, melamine, fabric, leather, glass, and other approved surfaces. The finish can be matched to the interior design of the auditorium, and the stacking pocket can be designed to blend seamlessly with the surrounding wall. For example, if the partition has a fabric finish, the pocket walls can be covered with the same fabric to create a continuous look when the partition is retracted.
Project Documentation and Coordination
Planning a stacking pocket requires close coordination with the architectural, structural, and mechanical teams. The top track must be supported by the building structure, and the pocket must not interfere with HVAC systems or electrical conduits. It is advisable to work with the partition manufacturer early in the design process to review the layout and develop detailed drawings. EBUNGE can provide project documentation to assist with this coordination, ensuring that all requirements are met.
Steps for Planning a Stacking Pocket
- Assess the space: Measure the auditorium dimensions, ceiling height, and structural constraints.
- Determine the stacking position: Choose a location that minimizes visual impact and maximizes usable floor area.
- Review the stacking route: Ensure the path from the open position to the stacking position is clear of obstacles.
- Design the pocket: Specify the pocket dimensions, including depth, width, and height, based on the number of panels.
- Integrate acoustic sealing: Plan for wall-mounted acoustic panel edges and other seals to prevent flanking.
- Coordinate with other trades: Work with structural, mechanical, and electrical engineers to avoid conflicts.
- Document everything: Prepare detailed drawings and specifications for the contractor.
