Sustainability
For more than 65 years, Supreme Perlite products have been used in various industries to enhance thermal performance, conserve water, promote healthy plant growth, and protect the environment. Perlite mining results in minimal disturbance to the land and supports jobs in agriculture, natural resources, transportation, engineering, packaging, distribution, and many more.

Thermal Performance
With an R-value of 2.5 per inch and up, expanded perlite’s excellent thermal resistance properties are used extensively to insulate walls, floors, line chimneys, steel storage tanks, as well as large LNG tanks and cold boxes.
Water Conservation & Protection
Perlite’s irregular surface area and customizable size mean it is increasingly valued for its potential to conserve moisture and purify or soak up contaminated liquids, sometimes in conjunction with other components, to help protect and conserve natural freshwater resources. Applications include stormwater filter cartridges, rooftop gardens, media filter drains, industrial waste-water treatment, biofiltration, liquid waste solidification, and moisture-retaining soil amendment.
Healthy Plant Growth
Perlite benefits the soil by helping to maintain healthy growing conditions for plants. Perlite provides a balance between air and water-holding capacity in the soil or growing media which translates to healthier plants while conserving the use of water and fertilizer. It is also widely used in indoor and hydroponic growing systems which make more efficient use of water through controlled irrigation systems.
Industrial Filtration & Adsorbent
Fine grade perlite is also used as baghouse pre-coat for industries required to filter exhaust air prior to discharge. Adsorbent grades of perlite are used to clean up industrial spills, or solidify liquid waste, and to decommission underground storage tanks.
