Types of Acoustics Board
Made from granular materials such as glass granulates, produced by crushing glass into particles and pressing them into form. The structure consists of voids between the granules, which cause sound waves to reflect, refract, and friction internally. This allows sound to be controlled, diffused, and mitigated in a balanced manner, perfectly suited for managing the overall acoustic quality of a space.
