Acoustic Sliding folding Partition

Acoustic Sliding folding Partition


The H.S. Engineers sound-isolation sliding partition / movable walls are a new way to divide spaces with elegance, while respecting the architectural environment in which they are inserted. H.S. Engineers sound isolating sliding partitions are composed of multiple individual elements. Movable wall partitions flow along a horizontal guide attached to the ceiling which is assembled as per our trademark design.

Our no floor track sliding partition system is simple, fast and safe. The advantage of an H.S. Engineers sound-isolating sliding partition / movable wall is its reduced storage space when stored.

How H.S. Engineers Sound Proof Sliding Partition works

The sliding panels are designed in tongue-and-groove mode and its surface finish can be made of precise Mica / laminated board, wood veneer, fabric etc. specified by customers. The movable partition wall is also equipped with vertical and horizontal external frames fabricated by aluminum profiles. The movable wall partitions consist of retractable mechanisms to move top and bottom seal manually, operated by the handle inserted in the panel stile. Turning the handle 45 degrees shall simultaneously extend or retract the top and bottom seals.

The sound insulation effect can reach up to 55 dB.

H.S. Engineers movable partition walls with aluminum frame have the most widespread application. The partition is constructed by a set of flat panels, ranging in width from 800mm to 1200mm. The panel is flexible with various specifications and characteristics to satisfy most requirements of design and budget. Its thickness can be 85mm or 100mm.

Each model comes with different grades of sound insulation as well as single or double sliding trolleys according to height and Panel stacking system at site.

Points of note

  • Only top hang , no floor track / guide
  • The wall panel is of double skin construction with a solid external aluminum frame fitted with our heavy duty rubber gasket at all four sides, as per our trademark design.
  • The panel faces are not fixed to the frame via hard contact and therefore when sound waves impact one side of the panel, the vibration caused will not be directly transferred to the opposite panel face.
  • The aluminum frame of the partition wall is either concealed ( TYPE – 90) or exposed ( TYPE -100) to create a flat and smooth edge
  • We can achieve a sound isolation of approx 55 dBA STC depending on site conditions.
  • Our heavy duty seals can adjust to an uneven floor, enabling better isolation in existing constructions.

Our trademark trolley system enables high flexibility, enabling different types of stacking.

Technical Features

  1. Track & Trolley

    Each panel shall be suspended on our trademark trolley system with maintainence free multiple Balbearings. The individual element is adjustable in height without opening of the ceiling.
  2. Retractable Pressure Seals

    The panel, once positioned, will realize a sealed effect via retractable pressure seals. The seals can be easily controlled or locked by means of simple on-site operation. The users can turn the waist-high operating handle to extract the pressure seals. The handle controls the top and bottom seals simultaneously. It is important that the sound isolating pressure seals can be properly extended. Our heavy duty rubber seals will be used in all the four sides of our operable wall system. Retractable drop down seal can extend by 20 mm
  3. Telescopic Panel

    Telescopic panel is the extension sleeve on the last panel through which the final closure of our partition wall is achieved. This ensures air tight sealing throughout our movable wall partition, thus reaching the desired sound insulation effect.
  4. Rubber Sealing Strip

    The EPDM rubber sealing strip is used to seal the gap between the sliding panel top / bottom and the track / floor respectively.
  5. Panel Sealing

    The EPDM rubber sealing strip is used to seal the gap between the sliding panel top / bottom and the track / floor respectively.
  6. Suspension System

Double roller suspension


Single Roller Suspension


The movable wall partition has 2 suspension modes –

  1. Single roller suspension
  2. Double roller suspension.

This is chosen by our engineers taking the load, height and width into account.

Panel Stacking

​Panels can be stacked in a variety of positions. Centre stacking and side stacking can be choose as per space available at site.
