Natural material of Thermal insulation, water conservation and fire resistance


Vermiculite is a mineral having cleavages. Vermiculite mined by AVI in Australia has superior water holding, thermal insulation and fireproofing characteristics. 


At about 1,000 particles of vermiculite expand at right angles to the cleavage into accordion-shaped pieces. Exfoliated vermiculite is lightweight and porous. Since an increase in bulk volume of AVI vermiculite is higher than any crude vermiculite mined in other countries, its applications are extensive: thermal insulating board, building materials and soil conditioning agent.
