Vulcanite Armor is a rock wool: basalt and dolomite, stitched to galvanised or stainless wire mesh. It is compliant with ASTM C592 Type I and III and tested per ASTM E84, with a Flame Spread Index of 0. How rock wool compares with glass wool and ceramic fibre is set out in rock wool vs glass wool vs ceramic fibre.
