CL Ceiling

Versatile linear metal ceiling

The CL Ceiling is a highly versatile linear metal ceiling system that combines design flexibility with technical performance. Thanks to its modular concept, different panel widths can be installed on the same carrier, allowing designers to freely mix and match modules within one ceiling layout.
The system easily integrates lighting, ventilation, fire detection, sprinklers and other technical installations, resulting in a clean and well-organised ceiling solution.
CL Ceiling is suitable for a wide range of applications, including:

  • Fire-resistant applications (steel & DuplexCoat®)
  • Humid environments (aluminium & DuplexCoat®)
  • Exterior applications
  • Projects with limited installation height (from 50 mm, without lighting)

Its timeless metal design makes CL Ceiling a durable and future-proof choice for both new-build and renovation projects.

“The strength of the CL Ceiling lies in its flexibility: one system, endless design possibilities.”

Flexible design and installation

CL Ceiling panels are available in lengths of up to 8.5 metres, creating a calm and uniform ceiling appearance. During installation, panels can be easily adjusted, which is a major advantage in spaces with irregular layouts.
All five panel widths fit on the same carrier and can be combined freely. Panels can also be aligned with the building’s structural grid and, with minimal intervention, even function as an ‘invisible’ band grid for partition walls.

Acoustic comfort

Good acoustics are essential for wellbeing and concentration. In spaces such as offices, classrooms, auditoriums and public buildings, poor acoustics can negatively impact comfort and productivity.
Perforated CL steel ceilings can be combined with an integrated acoustic fleece or acoustic insulation above the ceiling, significantly improving sound absorption and reducing reverberation. The result is enhanced speech intelligibility and a more comfortable indoor environment.
