VANK_BIO_DIAMOND is a sustainable sound-abosorbing acoustic panel. Vank_Bio_Diamond consists of a natural fiber composite that is formed into a dimensionally stable shape using an innovative forming technology. The natural fiber composite, made predominantly from bast fibers of annual plants, replaces petroleum-based and non-circulating molded parts made of polyurethane foam. Due to the lightweight properties of the natural fibers, we achieve a 20% reduction in component weight, while maintaining the same functionality of the panels.
