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.
