Supreme Perlite Co. Perlite

$12.95 / 4 Cu Ft  Regular $18.95

Supreme Perlite Company’s perlite is a mixed glassy silicate of volcanic origin which has a unique internal structure consisting of numerous tiny closed air cells surrounded by a large, exterior irregular surface.

Expanded Perlite is a ultra-lightweight, inert, sterile, permanent, incombustible, asbestos- free, non-toxic, rot and vermin proof and has a neutral pH. Its internal closed air-cell structure resists thermal transmission giving Perlite its inherent insulating properties. Its extremely large, open surface area offers benefits in other areas such as horticulture and filtration.
