When planning an office meeting suite, the interplay between office partition seals whiteboards is often overlooked. Yet, it is precisely at the junction of a movable partition and a wall-mounted whiteboard that acoustic performance can be compromised. EBUNGE movable partitions are designed to be individually movable, suspended from a top track, and can cross openings without a floor track. However, the effectiveness of the entire system depends on meticulous interface detailing. This article explores why the seal interface at wall-mounted whiteboards demands special attention and how you can plan for optimal acoustic performance in your next fit-out.
Understanding the Role of Seals in Movable Partitions
Movable partitions rely on perimeter seals to minimize sound flanking. These seals are typically compressed against adjacent surfaces—floors, ceilings, and walls—to create an acoustic barrier. In a straight run, the partition panels are individually movable and suspended from a top track, allowing them to be stacked at a planned position. The seals are part of the overall system that helps achieve the desired sound insulation. However, the performance of these seals is only as good as the surface they press against. If that surface is interrupted by a whiteboard, the seal may not achieve continuous contact, leading to potential sound leaks.
How Seals Work: A Conceptual Overview
Seals are designed to fill gaps and create a pressure-tight boundary. In acoustic terms, the goal is to reduce the transmission of airborne sound. The effectiveness of a partition system is often described using metrics like STC (Sound Transmission Class) or Rw (Weighted Sound Reduction Index). These are not direct decibel counts but rather ratings that reflect the overall sound insulation performance across a range of frequencies. For a seal to perform well, it must be properly compressed and maintained over time. Any irregularity in the mating surface can compromise the seal’s integrity.
The Whiteboard Interface Challenge
Wall-mounted whiteboards introduce a unique challenge. They are typically mounted on brackets that create a gap between the board and the wall. This gap can be a path for sound to bypass the partition seal. Additionally, the surface of the whiteboard itself may not be perfectly flush with the wall, making it difficult for a seal to achieve a continuous contact line. If the partition is designed to close against the wall, the seal must accommodate the thickness of the whiteboard and any mounting hardware. Without proper detailing, this interface can become a weak point in the acoustic envelope.

Why Interface Detailing Matters
Interface detailing refers to the careful design and coordination of all elements at the junction points. In the case of a whiteboard, this involves specifying how the partition seal will interact with the whiteboard and its mounting. It may require the use of special seal profiles, adjustable seals, or even a recessed whiteboard installation. The goal is to ensure that the seal can compress uniformly against a solid surface. If the whiteboard is not recessed, the seal might need to be designed to conform to the board’s surface, which is often not as rigid as a wall.
Acoustic Considerations: STC/Rw and Flanking Paths
When discussing acoustic performance, it’s important to understand that STC/Rw ratings are not simply a count of decibels. They are laboratory-derived metrics that indicate how much sound is reduced across a range of frequencies. In real-world installations, the actual performance can be affected by flanking paths—indirect sound transmission routes. A poorly detailed whiteboard interface can create a flanking path that bypasses the partition, reducing the overall effectiveness of the system. Therefore, even if the partition panels themselves are high-performing, the interface details must be addressed to achieve the desired acoustic outcome.
Flanking Paths: The Hidden Culprit
Flanking paths are any route that sound can take to get from one side of a partition to the other, other than directly through the partition. Common flanking paths include gaps around the partition, through ceiling plenums, or along adjacent walls. A whiteboard that is not properly integrated can create a flanking path along the wall surface. The seal is meant to prevent this, but if it cannot make full contact, the path remains. This is why interface detailing is not just a cosmetic concern but a critical acoustic one.
Planning the Layout: Straight, Turning, and Stacking Routes
EBUNGE movable partitions can follow straight, turning, and stacking routes. The layout review is an essential step in ensuring that the partition system meets the project’s needs. When a whiteboard is present, the route must be planned accordingly. For example, if the partition is to stack at a position where a whiteboard is mounted, the stacking depth must be sufficient to accommodate the partition panels without interfering with the whiteboard. Similarly, if the partition turns a corner near a whiteboard, the seal detailing at that junction becomes even more complex.
Stacking Positions and Whiteboard Clearance
The stacking position is where the partition panels are parked when not in use. This area must be designed with adequate clearance for the panels and their seals. If a whiteboard is located near the stacking area, there is a risk of the panels colliding with the whiteboard. Proper planning can ensure that the stacking area is clear and that the whiteboard does not obstruct the movement of the panels. This is part of the layout review that EBUNGE recommends for every project.
Finish Options and Their Impact on Sealing
EBUNGE offers a range of finish options, including laminate, melamine, fabric, leather, glass, and other approved surfaces. The choice of finish can affect the sealing performance. For instance, a fabric finish may have a slightly different surface texture than a laminate, which could influence how the seal compresses. However, the finish itself does not determine the acoustic performance; rather, it is the sealing system and its detailing that matter. Nevertheless, it is important to consider the finish in the context of the overall design and how it interacts with the whiteboard interface.
Glass Finishes: Special Considerations
Glass panels are a popular choice for modern office aesthetics. However, glass surfaces can be more challenging for seals to grip, especially if the seal is designed for a matte finish. In such cases, the seal may need to be specified with a different profile or material. This is a detail that should be discussed with the project team to ensure that the acoustic performance is not compromised.
Pass Doors and Interface Detailing
In many meeting suites, a pass door is integrated into the movable partition. The pass door itself requires careful sealing, and when combined with a whiteboard interface, the detailing becomes even more critical. The door must close tightly against the partition and the wall, and the seals must be coordinated to avoid gaps. If a whiteboard is mounted on the wall adjacent to the pass door, the seal at that point must be designed to accommodate both the door and the whiteboard.

Coordinating with Other Building Elements
Beyond whiteboards, there may be other building elements such as electrical outlets, light switches, or data ports that can interfere with the partition seal. All these elements need to be coordinated during the design phase. The key is to identify potential conflicts early and develop solutions that maintain the integrity of the acoustic barrier.
Project Documentation and Support
EBUNGE supports projects by reviewing layouts and discussing project-specific requirements. We encourage you to share your floor plans and details so that we can advise on the best approach for your movable partition system. Our team can help you plan the interface detailing for wall-mounted whiteboards and other elements. We can also provide documentation that outlines the recommended installation details, ensuring that the acoustic performance is achieved.
Why Documentation Matters
Proper documentation is essential for the success of any construction project. It ensures that all parties—architects, contractors, and installers—are on the same page. For movable partitions, documentation should include detailed drawings of the seal interfaces, including the whiteboard junction. This helps to avoid costly mistakes during installation and ensures that the final result meets the acoustic expectations.
Best Practices for Whiteboard Interface Detailing
To achieve a successful interface between office partition seals and whiteboards, consider the following best practices:
- Recess the whiteboard: If possible, mount the whiteboard so that its surface is flush with the wall. This provides a continuous surface for the seal to press against.
- Use a backer board: Behind the whiteboard, install a rigid backer board to create a solid surface for the seal to contact.
- Coordinate with the partition manufacturer: Work with EBUNGE to determine the appropriate seal type and profile for the specific whiteboard installation.
- Consider the mounting brackets: Ensure that the brackets are not in the path of the seal. If they are, they may need to be relocated or the seal designed to accommodate them.
- Plan for maintenance: Seals may need to be adjusted or replaced over time. Ensure that the whiteboard does not obstruct access to the seals.
Common Mistakes to Avoid
One common mistake is to assume that a standard seal will work regardless of the whiteboard. Another is to install the whiteboard after the partition, leading to gaps that are difficult to fix. It is also a mistake to ignore the impact of the whiteboard on the stacking area. By avoiding these pitfalls, you can ensure a better acoustic outcome.
Frequently Asked Questions
Why is interface detailing important for office partition seals at whiteboards?
Interface detailing ensures that the partition seal makes continuous contact with a solid surface. Without it, gaps around the whiteboard can create sound leaks, reducing the acoustic performance of the partition system.
Can a standard partition seal work against a wall-mounted whiteboard?
In some cases, but it depends on the mounting method and the surface of the whiteboard. A standard seal may not be able to compress uniformly against a whiteboard that is not flush with the wall. It is best to discuss the specific installation with the partition manufacturer.
What is a flanking path in acoustics?
A flanking path is an indirect route that sound can take to bypass a partition, such as through gaps or along adjacent surfaces. Poor detailing at a whiteboard can create a flanking path that compromises the acoustic barrier.
How can I ensure my whiteboard does not affect the partition’s acoustic performance?
You can recess the whiteboard, use a backer board, and coordinate the seal type with the partition manufacturer. It is also important to plan the layout so that the whiteboard does not interfere with the partition’s stacking or movement.
