Dynamic rhythm and acoustic performance. The 4sound® Barcode collection reinterprets acoustic cladding through an irregular composition of solids and voids, creating surfaces with a strong graphic and architectural identity. The alternation of different sections generates movement and depth, transforming walls and ceilings into continuous three-dimensional elements. Developed on the standard slat width of 133 mm, the system combines 32 mm, 16 mm, and 48 mm modules, offering high compositional freedom and maximum visual continuity through a tongue-and-groove joint system. The panel’s technical structure is engineered to ensure high acoustic absorption performance, contributing to reverberation reduction and improved speech intelligibility in high-traffic environments.
