Sound-absorbing ceiling panel

Catalogue2D/3DTechnical Specifications

Creativity and functionality: Flag offers plenty of options for creating high-impact, dynamic volumetric effects without, however, undermining the very features of this removable sound-absorbing panel. By acting as a flag, the Flag removable panel guarantees to block the volumetric wave, minimising reverberation and making rooms acoustically comfortable. This versatile option can be installed on the ceiling with dedicated tracks, or using adjustable cables to position the panels at different heights for creative, original solutions. LED lighting systems can also be incorporated into the bottom part of the Flag panels, guaranteeing excellent lighting.


Efficient acoustic absorption, duration, safety: the Flag sound-absorbing panels have been devised and designed to guarantee optimal sound absorption, thanks to materials chosen with particular care.

Details of materials


The integration of modern LED lighting systems into sound-absorbing panels is a highly interesting specification on the market which Caruso Acoustic has been able to achieve. Guaranteeing the correct light output through lighting technology calculations means meeting customers’ needs and offering them effective applications based on different power and angle parameters for the beam of light. Below is the visible in-line LED lighting system available for the Flag panel.

Visible Dimensions: 2,5 cm
Light Color: 5000°K, 4000°K, 2700°K
Driver: on/off or dimmer
Certifications: CE


Flag sound-absorbing ceiling panels are available in a number of different standard sizes, so they can adapt to any acoustic and architectural requirements. They can be assembled horizontally or vertically, either on tracks or hung from the ceiling by thin cables.

Panels with special measurements can be made upon request for specific project requirements.


  • Fixing with bars
  • Fixing with cables
The panels can be fixed to the wall or ceiling using dedicated tracks with made-to-measure sliding bars.
The panels can suspended from the ceiling using the kit composed of adjustable vertical cables.


Our sound-absorbing products have been tested in reverberation chambers in accordance with standard UNI EN ISO 354 and are divided according to their type of application (walls, horizontal hanging cables, free-standing, etc). The technical data sheets and certifications are available upon request. Silente, Nuvola, Flag, Scriba and D-Space finished products meet European fire safety regulatory requirements in accordance with standard UNI EN 13501-1 and are certified under class B-s2,d0 for the Basotect melamine resin by Basf® and under class B-s1,d0 for Whisper® by Stratocell®; they also meet American requirements in accordance with USA ASTM E84- 15b standard. Moreover, they are approved for fire prevention by the Italian Ministry of the Interior. These products also comply with existing health and safety legislation for the new formaldehyde classification. In particular, they are certified against the release of formaldehyde under EN 717-1:2004 with values of mg/m3 <0.01 – ppm <0.01.
