Fibres
Basalt fibre
A dark mineral fibre melt-spun from selected basalt rock, positioned between conventional glass and higher-cost speciality reinforcements.
In simple terms
A dark mineral fibre melt-spun from selected basalt rock, positioned between conventional glass and higher-cost speciality reinforcements.
Best for
Corrosion resistance, fire exposure, electrical insulation and robust civil or marine structures.
Watch out for
Property consistency depends on mineral source; design databases and global supply are less mature than E-glass.
Typical applications
Rebar, concrete reinforcement, pipes, marine panels, automotive heat shields and fire-resistant textiles.
