BL Ceiling

BL Ceiling

Linear metal ceiling with open joints

The BL Ceiling is a linear metal ceiling system with open joints, combining architectural rhythm with strong acoustic performance. Its open structure creates a dynamic ceiling appearance while allowing seamless integration of lighting, ventilation, sprinklers and other technical installations.
Thanks to its modular design and durable materials, the BL Ceiling is suitable for a wide range of interior and exterior applications, from offices and public buildings to commercial and leisure environments.

“BL Ceiling brings structure and acoustics together in a visually expressive ceiling design.”

Architectural freedom and flexibility

The BL Ceiling system is available in multiple module sizes, each creating a distinct visual rhythm. Panels can be installed in long lengths of up to 8.5 metres, resulting in clean lines and a consistent ceiling image.
The open joint design enhances spatial depth and allows easy coordination with the building grid. BL ceilings can be installed as continuous ceilings or ceiling islands and are compatible with both standard and more expressive architectural concepts.
Different finishes, perforation types and colours allow the BL Ceiling to be tailored to the specific character of each project.

Acoustic comfort

Good acoustics are essential in spaces where people work, meet or relax. The BL Ceiling is designed to improve acoustic comfort by reducing reverberation and background noise.
Perforated BL panels can be combined with a non‑woven acoustic fleece or acoustic insulation above the ceiling. This significantly enhances sound absorption and speech intelligibility, contributing to a calmer and more comfortable indoor environment in offices, classrooms, auditoriums and public spaces.
