Why Partition Stacking and Acoustic Clouds Must Be Planned Together
When a hotel ballroom is subdivided by a movable wall, the panels must travel to a parking position. The suitability of each route and parking arrangement depends on the approved layout, circulation, ceiling interfaces and operating sequence.
Movable walls from EBUNGE are top-hung and run on an overhead track. They do not require a floor track, which simplifies the floor finish. However, the overhead track must be continuous along the entire travel path, including turns and the stacking zone. This article explains what to review and what to confirm with your project team.
Understanding the Movable Partition System
EBUNGE movable partitions consist of individual panels that are suspended from a top track. Each panel moves independently, which allows flexible configurations. The panels cross the opening without a floor track, leaving the floor clear. When not in use, panels park in a planned stacking position, often a pocket or recess at one side of the room.
The stacking layout is customized to your project. It can be straight, turning, or a combination, depending on the available space. The track route must be reviewed from the architectural layout to ensure that panels can travel smoothly from the dividing line to the parking area.
Top-Hung Operation and Clear Floor
This is a significant advantage for ballrooms where the floor finish is continuous and easy to clean. The exact route, junction arrangement, continuous overhead path and parking position must be confirmed from the coordinated project drawings. The exact overhead route and support arrangement must be confirmed by the responsible project team from coordinated drawings.
Customized Stacking Configurations
Parking style is not one-size-fits-all. It depends on the shape of the room, the location of columns, and the desired aesthetic. Some projects use a straight stacking pocket; others use a 90-degree turn into a side recess.
What Are Ceiling-Mounted Acoustic Clouds?
They are often used in large spaces like ballrooms to improve speech intelligibility and control noise. Clouds can be flat, curved, or angled, and they are typically made of sound-absorbing materials with a fabric or perforated facing.
They help control sound within each subdivided space. However, their placement must not interfere with the partition’s travel path or its stacking zone.

Why Coordination Is Critical
Cost and maintenance requirements depend on the selected configuration, finish and project conditions and require project-specific confirmation.
Key Coordination Points for Stacking and Acoustic Clouds
To achieve successful coordination, the project team must address several key points during design development.
1. Track Route and Clearance
The overhead track must have a clear path from the partition line to the stacking area. This includes horizontal clearance for the panels as they swing or turn, and vertical clearance for the track and carriers. The exact dimensions depend on the panel size and the track system, which must be confirmed with the partition supplier.
2. Stacking Zone Depth and Width
The stacking zone must be deep enough to accommodate the stacked panels. The depth is typically the width of one panel plus a small gap. The width is the sum of the panel thicknesses. Sometimes a cloud can be placed higher, but this must be reviewed.
3. Ceiling Structure and Support
Coordination is needed to avoid conflicts between hanger rods, cables, and the track support brackets.
4. Integration with Other Services
Lighting, sprinklers, HVAC diffusers, and speakers are often mounted in the ceiling. Similarly, lighting fixtures should not be placed where they would be hidden by stacked panels.
5. Access for Maintenance
The partition track may need periodic inspection and adjustment. The design should allow access to these elements without having to dismantle the other system.
Reviewing the Layout: Straight, Turning, and Stacking Routes
Every project is unique. The partition route may be straight, or it may involve a turn. The stacking area may be a straight line or an L-shaped pocket.
Straight Routes
The track runs in a straight line from the partition line to the stacking pocket. The stacking pocket is often a recess in the wall, which may be closed with a door or panel to hide the stacked partition.
Turning Routes
If the stacking area is not directly in line with the partition, the track may need a curve or a switch.
Stacking Routes with Multiple Panels
For large openings, the partition may consist of many panels. The stacking area must be long enough to hold all panels. In some cases, panels may be stacked in two or more rows, but this requires a wider pocket.
Finish Options and Aesthetic Integration
When selecting finishes, consider how the partition will look when stacked. The stacked panels are often visible in a pocket or recess. The finish should be consistent with the surrounding wall.
Coordinating Finishes with Acoustic Clouds
Acoustic Considerations: Seals and Flanking Paths
Review the ceiling interface, panel route and stacking position together.
Movable partitions achieve sound insulation through mass, seals, and the absence of gaps. The panels are designed to fit tightly against the ceiling, floor, and adjacent panels. Perimeter seals, such as drop seals at the bottom and compression seals at the top and sides, help close gaps. However, the effectiveness of these seals depends on the condition of the surrounding surfaces and the accuracy of installation.
However, they can influence the sound field in the room, which may affect the perceived privacy. Visible references can support layout discussion but do not verify hidden construction or performance. But this is not a substitute for proper partition construction.
Understanding STC and Rw
Project Documentation and Coordination
Successful coordination requires clear documentation. The partition supplier should provide detailed drawings showing the track route, stacking area, and interface details.
What to Include in the Drawings
The drawings should show the following:
- The exact location of the partition line and the stacking area.
- The track route, including any curves or switches.
- The clearance envelope for the panels.
These drawings should be updated as the design evolves. Regular coordination meetings are essential to resolve conflicts early.
Discussing Project-Specific Requirements
Every project has unique requirements. They can help you determine the appropriate panel configuration, stacking layout, and seal details.
Frequently Asked Questions
Can acoustic clouds be placed directly above the partition stacking area?
It depends on the clearance needed for the stacked panels and the track system. In some cases, clouds can be placed higher, but they must not interfere with the vertical clearance or the operation of the panels. A detailed review of the stacking area is required.
Do acoustic clouds affect the sound insulation of the movable partition?
The partition’s performance depends on its construction and seals. However, clouds can reduce reverberation, which may improve speech privacy in some situations.
What information do I need to provide to the partition supplier for coordination?
The supplier will need to know the opening size, the desired stacking location, and the finish preferences.
Can the partition track be curved to avoid acoustic clouds?
Yes, the track can be curved if the layout requires it. However, curved tracks require more space and may limit the panel size. This should be reviewed with the supplier.
How do I ensure that the acoustic cloud layout does not conflict with the partition route?
Early coordination is key. Use building information modeling (BIM) if available to detect clashes. Regular meetings and drawing reviews will help avoid conflicts.
Conclusion: Plan Early and Confirm Project-Specific Details
The key is to start early and involve all stakeholders. Review the layout, understand the partition system, and communicate clearly.
