One of the benefits of mineral fiber ceiling tiles is that they are heavier and denser than the ones made of fiberglass. Because of this feature they are much better at impeding sound travelling from room to room. This feature allows these panels to excel in higher frequency environments. Mineral fiber ceiling tiles will generally have a higher ceiling attenuation class (CAC) and a lower noise reduction coefficient (NRC).
Perlite is a volcanic glass that, when heated, expands and forms a lightweight granular material. It is valued for its excellent thermal insulation properties, which can enhance energy efficiency in buildings. When combined in the right ratios with other materials, perlite provides an additional level of sound absorption, further enhancing the acoustics of a space.
