Perlite and the Environment
Perlite is a versatile mineral that is mined and processed with negligible impact on the environment. When perlite ore is expanded or “popped” by rapid, controlled heating, it expands up to 15 times its original volume and takes on a foam-like cellular appearance – essentially clusters of microscopic glass bubbles, creating a porous structure. This physical transformation makes expanded perlite an extremely effective aggregate.
Many in the green community recognize perlite-enhanced products as high-performance solutions drawn from a natural material of nearly unlimited supply throughout the world.
