Manufactured from natural rocks (basalt and dolomite) melted at high temperatures to form a molten matrix, then processed through an air stream to create long fibrous strands. The material is chemically and biologically inert, free from plant pathogens, and provides superior thermal insulation performance.
- High temperature resistance up to 1000°C
- Superior noise control capabilities
- Non-combustible with zero flame spread
- Minimal moisture absorption and shrinkage
