Vermiculite board is a lightweight, non-combustible insulation material manufactured from expanded vermiculite particles combined with specific inorganic binders through compression and heat treatment. The unique internal structure contains numerous interlayer voids, providing excellent thermal insulation properties with thermal conductivity ranging from 0.09 to 0.18 W/(m·K). These boards maintain structural integrity at temperatures up to 1200°C and are available in standard thicknesses from 15mm to 50mm. The material offers combined benefits of fire resistance, thermal insulation, and acoustic dampening, making it ideal for Australian construction applications including fireplace surrounds, register plates, fire door cores, and bushfire protection systems.
