Our A60 class bulkhead fireproof rock wool is engineered for high-grade fire division areas on vessels and offshore platforms. With a thickness of 30mm, it meets the highest IMO A60 class fire-resisting division standard. Manufactured with specialized processes, it effectively blocks flame and heat penetration during fire, ensuring the non-fire side temperature remains within limits for 60 minutes.

Meets IMO A60 class fire-resisting standard, maintaining non-fire side temperature ≤140°C for 60 minutes, critical area safety assurance.
Achieves A60 class fire rating at just 30mm thickness, minimizing space occupation in compact vessel structures.
High acidity coefficient and specialized process ensure no shrinkage or powdering at high temperatures, maintaining 60-minute fire integrity.
Rock wool is Class A non-combustible, with no burning or toxic fumes, ensuring crew safety.
Excellent sound absorption and low thermal conductivity reduce noise and heat transfer between compartments.
