Perlite (4 cu ft. Bag)

Perlite is a mixed glassy silicate of volcanic origin. Its unique internal structure consists of numerous tiny closed air cells surrounded by a large exterior irregular surface. Expanded Perlite is 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.
