Vermiculite is an entirely and naturally occurring mineral, similar
to mica, that is sold both in its natural state and by exfoliating
the core. Exfoliation is the term used to describe the expanding
process raw vermiculite goes through under extreme heat, rendering
the material naturally layered, perfectly suited for trapping air
and moisture. It does not create any waste by products during
processing and is inert, non-toxic, fire resistant and is capable
of holding many times its weight in water.
It has a wide range of uses in the horticulture industry as well as
a variety of industrial applications from insulation to filler in
the plastics industry.
Vermiculite has properties that make it an ideal soil additive for
horticultural purposes. In its expanded form, the mineral improves
soil aeration and provides excellent moisture retention.
Horticultural vermiculite is sterile, non-toxic, odorless and
permanent. It does not deteriorate, mold or rot and it typically
maintains a neutral 7.0 pH level.
In addition to its horticultural and agricultural uses, vermiculite
is used extensively by the commercial and home construction
industries. The mineral is an important additive to everything from
gypsum plaster to acoustic and soundproofing materials. It is used
in insulation and for fireproofing as well as for packing,
filtration, and absorption. It is added to cement, paint, sealants
and dozens of other materials for countless industrial
