85 Series Acousitc
Operable Wall

overview

Doormax 85 series Acoustic Movable Partition System employs cutting-edge soundproofing technology, integrating materials such as steel sheets, sound-dampening mats, and acoustic panels to achieve an impressive sound transmission class (STC) rating ranging from 45db to 52db. The baseboard 15mm/18mm plywood, MDF, HDF, or HPL baseboards establish a reliable foundation for exceptional acoustic performance.

Offering a range of surface finishes including bare boards, plywood, melamine, fabric, PU, HPL, and wood, the system caters to diverse aesthetic preferences. It is versatile, accommodating optional fire retardant features and is suitable for heights ranging from 2.5m to 5m. The system provides single or double-leaf doors, ensuring convenient passage while maintaining soundproofing integrity.

Crafted with a robust outer frame constructed from aluminum alloy, and an inner frame combining 3.0mm hot-dip galvanized C-shaped steel and 1.2mm hot-dip galvanized square steel tubes, durability is guaranteed. Featuring high-density 100kg/m³ rockwool and a door thickness of 90mm, the 85 series system establishes a new standard for acoustic solutions.

 
Typical SPECIFICATIONS
Doormax 85 Series Acoustic Operable Wall is system with superior features. Panels are used in places that require high levels of sound insulation. It offers excellent ease of use, offers a high level of acoustic and thermal insulation. The assembled panels are joined horizontally with the help of magnetic profiles. The insulating materials used in the panel will vary based on the requirements of the STC in the room and the needs of the user. By using materials with superior technical properties, the insulation values reach the maximum. The panel system can be safely used in conferences, meetings, weddings, ballrooms, invitation rooms, and educational institutions.

Advantages In Details
Doormax Door with specifications 2

1. Horizontal seals

The principle of double-skin construction is applied consistently in the seal area in order to ensure maximum sound insulation. A spindle mechanism extends the spring-loaded, flexible doublechamber seals against the floor and the ceiling track. Any irregularities in the flooring are offset by spring-loaded double-cham-ber seals. The contact force of the sealing strips does not place excessive strain on screed floors, but does ensure that the Doormax system is sufficiently stable to prevent the panels moving.

2. Corner seals

Doormax resolves the technical issue of corner seals with specially designed, elastic corner pieces that also reinforce the stability and sound insulation properties of the system

3. Vertical seals

All Doormax models have flexible, vertical sealing strips to ensure the best possible seal for maximum sound insulation. The strips extend some distance into the panels to ensure positive interlock

4. Magnetic strip

The individual panels are centred via the magnetic strips to guarantee sound, positive locking and sealing

5. Cover panels

The cover panels are clipped on as freely oscillating bodies to ensure optimum sound insulation with minimum system weight. The panels can be replaced without removing the elements. Their surfaces can be coated or covered with any conventional interior design material.

6. Sound insulation material

The various Doormax models can be fitted with additional insulation materials according to the specified acoustic requirements.

7. Operating handle

In manual systems, the element sealing strips are operated using a crank. The crank has a captive bayonet fitting to prevent it from being pulled off. The bayonet arrangement is easy to disengage and prevents crank slippage.

8. Frame

The frame is of torsionally stiff steel and aluminium construction. Transverse forces will not, therefore, cause deformation of the frame. This, combined with the panels mounted in acoustically free suspension, means elements are able to offer both exceptional strength and outstanding sound insulation

9. Roller assemblies

The dampening track roller assemblies prevent the transmission of impact forces and operating noise, so protecting element, track and carrier.
