  • Cost-oriented

    Technically excellent and cost-oriented solution.

    Nontoxic

    Light, non-toxic, fiber-free, odorless and acid-resistant.

    Refractory

    Depending on the product variation, application temperatures up to 1100 ° C.

    CHARACTERISTICS

    Our VIREboard vermiculite boards with a density of 375-700 kg/m³ and a maximum application temperature of 1100 °C are often used in fireplaces and boilers. Due to the good mechanical load capacity, the boards are also suitable for linings of the combustion chamber, insulation of doors and lids.

    Vermiculite panels are also used in the aluminum industry (also suitable for direct contact with aluminum) and the steel industry. Vermiculite sheets can be processed into different shapes. This is done exactly according to customer requirements and specifications.
