Our VIREboard vermiculite boards with a density of 475-700 kg / m³ and a maximum application temperature of 1,100 C are often used in stoves and boilers. Due to their good mechanical strength, the panels are also suitable for lining the combustion chamber and insulating 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.
- different densities depending on the application
- unclassified material
- Cost efficient
- Technically excellent
- Fiber free
- Acid resistant
