—Perlite's acoustical properties make it an ideal loose-fill insulation, reducing airborne sound transmission through walls.  Lightweight 8 in. (20 cm) masonry block filled with perlite achieves an STC of 51 which exceeds HUD sound transmission standards. Perlite is also added to plasters, ceiling tiles and walls to enhance sound absorption in these materials.

—In the agrichemical industry, perlite is used as a carrier for pesticides and herbicides, fertilizer bulking, and pelletized seeds.

—Perlite is used in environmental applications to absorb oil, and to control and clean up pollution. It is also blended with soil to filter stormwater runoff, reduce rainwater surge from green roofs, and solify industrial sludge.

—Beer, wine, juices, chemicals, pharmaceuticals, oils, acids, sugars, bio diesels, and water (potable, swimming pool, and storm runoff) are all filtered with perlite that has been expanded and crushed to form a maze of microscopic pathways.
