Our A30 bulkhead fireproof rock wool is specially engineered for marine and offshore bulkhead systems, with a thickness of 30mm, meeting IMO A30 class fire-resisting division standards. Made from premium rock wool through advanced processing, it effectively prevents flame spread during fire, ensuring the non-fire side temperature remains within limits for 30 minutes. The lightweight design reduces vessel deadweight, improving cargo capacity. With excellent acoustic and thermal insulation, it is ideal for passenger ships, cargo vessels, and offshore platforms.

Meets IMO A30 class fire-resisting standard, maintaining non-fire side temperature ≤140°C for 30 minutes, effectively blocking flame spread.
Only 30mm thickness significantly reduces bulkhead system weight, improving cargo capacity and reducing fuel consumption.
Rock wool is Class A non-combustible, with no burning or toxic fumes, ensuring crew safety.
Rock wool fiber structure provides good sound absorption, effectively blocking sound transmission between compartments for enhanced comfort.
High acidity coefficient ensures salt spray and moisture resistance, maintaining stable performance in marine environments.
