FAQ – Frequently Asked Questions About OPTIMAL System’s Mobile Walls and Panels

Yes, OPTIMAL movable walls are tested for resistance to mechanical stress, including crowd pressure and impact. The systems comply with applicable safety standards for use in commercial facilities. Long-term wall performance is supported by after-sales service, and the doors can be equipped with panic bars to facilitate evacuation scenarios.

Yes, on the OPTIMAL mobile wall A module with a door leaf function can be used in either a single-leaf or double-leaf configuration. The passageway can be equipped with a panic bar, a door closer, and an access control system, which is essential in facilities with heightened evacuation requirements.

In the manual , the movable wall is operated using the included crank. In the version semi-automatic modules are unfolded manually, while the extension and retraction of the lower and upper horizontal pressure bars and the locking of the wall are performed by an electric drive. The semi-automatic version reduces the time required to open and close the system in high-traffic areas.

No. The OPTIMAL movable wall does not interfere with the floor and does not have a floor guide. The tracks are attached to the structural elements of the ceiling of the floor above, and the installation method is selected individually based on the type of ceiling during the design phase. After the tracks are installed, the modular components are manufactured and, in the second stage, installed in the prepared tracks.

Standard processing takes 4 to 8 weeks, depending on the system configuration and the type of ceiling. The installation of the movable wall is carried out in two stages. The first stage involves installing the track and taking the final measurements of the wall; the second stage involves installing the modules in the prepared guides. Technical specifications and instructions are available in the section Downloads, and examples of implementations in projects.

Axial parking is a single-trolley systemthat allows modules to be moved and stored along the wall axis at one or both ends of the track and rotated 90 degrees. Side parking is a two-carriage system, which allows the modules to be routed to a pre-designed storage compartment outside the wall line. The choice of system depends on the room layout and available storage space; it is selected by the design department during the conceptual phase of the OPTIMAL movable wall system.

Track for a movable wall We recommend installing it before the suspended ceilings are closed. The system does not interfere with the floor and does not have a floor guide—the tracks are attached to the structural elements of the ceiling of the floor above. Including the track early in the fit-out schedule eliminates conflicts with building services; the following are helpful during the design phase: BIM objects.

Yes, OPTIMAL’s design department selects the installation method based on the type of ceiling. The standard offering is designed for installation on a reinforced concrete ceiling—for other structural solutions (steel ceiling, wooden ceiling, joist ceiling), the mounting method is determined on a case-by-case basis. This requires consultation with the design department before finalizing the order.

The maximum height and width of the movable wall are selected individually to the room’s geometry during the design phase. OPTIMAL 110 modular system It allows even large conference and multipurpose rooms to be divided, and the modules adapt to the final dimensions determined after the track is installed. The initial selection of parameters allows for online configurator.

Yes. OPTIMAL Mobile Acoustic Wall It provides high sound insulation while maintaining full flexibility in space division. Acoustic performance is determined not only by the system’s Rw value, but also by the proper installation of pressure strips and the tightness of the joints with surrounding partitions. Therefore, sound insulation performance under actual site conditions is determined based on the configuration confirmed in the ITB classification.

Rw is a weighted sound insulation index, expressed in decibels, describing a partition’s ability to reduce airborne sound between rooms. The higher the Rw value, the more effectively the movable wall provides acoustic separation between adjacent areas. For conference rooms and spaces requiring confidentiality during conversations, walls with high Rw ratings are essential.

Mobile acoustic walls from the OPTIMAL 110 series achieve sound insulation up to Rw = 57 dB, depending on the module’s configuration. These values are confirmed by the ITB acoustic classification. OPTIMAL 110 Plus Fire Fire-Rated Version It combines sound insulation with EI30 fire resistance. The selection of the appropriate Rw level depends on the room’s function—it differs for a conference room versus an open-plan office area.

The EI30 rating means that the partition maintains its fire resistance (E) and thermal insulation (I) for 30 minutes under fire conditions. In practice OPTIMAL 110 Plus Fire Movable Partition During this time, it prevents the spread of fire and limits the rise in temperature on the protected side, allowing time for evacuation and for the fire department to respond. The required fire resistance class for a specific building is specified in the construction design and in technical and building codes.

Yes. System OPTIMAL 110 Plus Fire This is a mobile fire wall with an EI30 fire resistance rating, certified by the ITB. It combines the function of a sliding room divider with fire safety requirements, allowing it to be used where it is necessary to separate fire zones while maintaining flexibility in the layout. Certifications and classifications are available in the section Download.

The OPTIMAL 110 Plus Fire system has a fire reaction class of B-s2,d0, which means a flame-retardant material with very limited smoke emission and no burning droplets. The complete OPTIMAL 110 Plus Fire wall is additionally classified for fire resistance in the EI30 class. The fire reaction class and the fire resistance class are two different parameters.

Acoustic panels absorb sound wave energy, converting it into heat within the material’s porous or perforated structure, which reduces sound reflections within the room and shortens the reverberation time. They do not block sound between rooms (that is the purpose of walls with a high Rw value), but they do improve acoustic comfort within a given space—they enhance speech intelligibility and reduce reverberation. For rooms intended for verbal communication, the PN-B-02151-4:2015 standard specifies a reverberation time in the range of 0.6–1.0 s. See the full guide: How do acoustic panels work?

αw is the weighted sound absorption coefficient determined in accordance with PN-EN ISO 11654 across five octave bands in the range of 250–4000 Hz. NRC (Noise Reduction Coefficient) is the average absorption value for the frequencies 250 Hz, 500 Hz, 1000 Hz, and 2000 Hz, used primarily in specifications of American origin. Both indices describe sound absorption performance acoustic panel – the higher the value, the better the acoustic properties.

Acoustic wall and ceiling panels are used in conference rooms, open-plan offices, reception areas, private offices, as well as dining and educational spaces, where controlling reverberation and ensuring speech intelligibility are important. The selection of the number and placement of panels depends on the room’s volume, the type of surface, and the target reverberation time. Examples of applications are presented in projects.

No. The panels are mounted on walls or ceilings using mounting systems selected to suit the surface, which allows for installation even in occupied spaces. The layout of the panels is designed to achieve the desired acoustic effect while maintaining the visual cohesion of the interior.

CPL and HPL are the same material — a high-pressure laminate composed of paper and resins, with a density of at least 1.35 g/cm³, evaluated according to the same EN 438-3 standard. The only difference lies in the production method: CPL (Continuous Pressed Laminate) is produced using continuous technology in double-belt presses, while HPL (High Pressure Laminate) is produced in multi-deck presses. OPTIMAL Poland supplies CPL laminates as a full-fledged substitute for HPL—from the same manufacturers and made from the same raw materials. See the full Comparison: HPL vs. CPL. The material is also used in laminate panels.

Yes. CPL and HPL Laminates They have identical performance characteristics because they are evaluated according to the same EN 438 standard. This includes resistance to abrasion, impact, scratches, water vapor, and stains. For vertical (wall) applications in Class V, the EN 438-3 standard requires abrasion resistance of at least 150 IP revolutions. CPL offers the same durability parameters as HPL, with greater flexibility in sheet formats and lengths.

CPL/HPL wall panels are used in high-traffic commercial facilities – hotels, office buildings, retail facilities, and public buildings – where abrasion resistance and ease of cleaning are key. The material serves as a durable, attractive wall finish in high-traffic areas. We showcase its applications in various facilities in projects.

OPTIMAL Mobile Walls allow you to reconfigure the layout in just a few minutes while maintaining high sound insulation, which allows for make better use of the conference room space. See An example of a conference room with movable walls and others projects by OPTIMAL System.

For conference rooms and multifunctional hotel spaces, we recommend OPTIMAL 110 acoustic systems with high Rw ratings; and for areas requiring fire compartmentation— OPTIMAL 110 Plus FIRE, rated EI30. The choice of a movable wall system depends on the required sound insulation, fire resistance rating, and method of storing the modules. The design department selects the optimal configuration based on the floor plan and the building’s requirements.

The price of a movable wall depends on: the partition’s surface area, the required sound insulation (Rw), the fire resistance class, the module parking system, the operating method (manual or semi-automatic), and the type of finish. For this reason, each project is priced individually, based on the floor plan and technical specifications of the facility. The initial selection of parameters allows for configurator, and the sales department prepares a quote after a design consultation.
