Raised floor panel

Acoustic panels

Modern architecture uses a high proportion of sound-reflecting materials such as e.g. Exposed concrete and glass, which influence the reverberation time unfavorably. As a result of this – beside room facilities and people – practically only the floor is available as absorption area.

Type and extent of sound absorption in the acoustics raised floor panel are determined by three elements:

  1. carpet

  2. Hole grid of the bottom plate

  3. absorber

Each of these three components significantly influences the measured and sensorially perceived result of the achieved modern room acoustics.

By varying the three elements, the acoustic raised floor can be adapted to the respective requirements.


  • Sound reflecting is absorbed through the carpet into the panel element
  • Significantly improved absorption values compared with any other hollow floor solution
  • No effects on the installations in the hollow space
  • No restrictions on the ventilation through the hollow space
  • Combinations with conventional panel elements assured
  • The mechanical and static properties are maintained
  • Different versions provide «made-to measure acoustics»
  • We use the know-how acquired by the market leader for modern acoustic panels
Acoustic floor for modern architecture

Horstmann & Berger (Altensteig/D) were responsible for calculating the acoustics.

Each of these three components (carpet, hole pattern, absorber) exerts a significant influence on the perceived and measured results of the implemented modern room acoustics and sound reflecting.

The three elements can be varied to adapt an acoustic raised floor to meet the specific requirements.

Part of the campus project for Novartis Pharma AG in Basel, the modern Sanaa Building is a classic example of the way in which acoustic raised floor panels can be used.

This newly constructed 6-storey building complex comprises two longitudinal wings, each measuring 5.6 x 84 meters, and most of the rooms are used as modern offices.

The longitudinal facades are completely made of glass and fair-faced concrete has been used for the walls and ceilings.

Acoustic Panel

System description

Perforated loose-lay carpet tiles.

Acoustic panels made of perforated steel with integrated absorbers. Galvanized 1.00 mm steel plate on the underside. Protective film on top, which must be removed before fitting the floor covering! Fiber-reinforced peripheral zones and under-wall regions with panels made of fiber-reinforced calcium sulfate.

Made of galvanized blue-passivated steel, the pedestals have a stepless height adjustment facility and are characterized by the precision guidance for the adjusting pin.

Bolt adhesive or a mechanical locking device

Bedding the base of the pedestal in pedestal glue

Stringers are used for installation heights of 500 mm and more (optional)

Permanently pretensioned wall connection with sealing tape for acoustic decoupling and to absorb movement.

It is advisable to apply a floor coating to seal unfinished floors where air ducting installation panels are to be fitted.

Sophisticated architecture and excellent acoustic room conditions are by no means mutually exclusive.

Acoustic raised floor panels are fitted in offices, commercial buildings and administration buildings, as well as auditoriums.

Acoustic raised floors are used in modern office, commercial and administrative buildings as well as in auditoriums.

A classic case for the use of acoustic raised floors is the Sanaa building, as part of the campus project of Novartis Pharma AG, in Basel.

Here, a new building was built, consisting of 2 longitudinal wings of 5.6 x 84 m each.
