Description
Modular metal ceiling system for suspended acoustic ceilings in new builds and existing buildings. Stress-free installation without height differences, including on existing T-profiles during refurbishment. Optionally combinable with a cooling and heating function, hygiene equipment, and ball-impact resistance. The surface can be individually printed via COLORPRINT, turning the cassette into a design element. Square and long-field cassettes in 160 tested configurations, matched to varying room and absorption requirements.
