Our A60 fireproof rock wool is engineered for critical deck areas on vessels and offshore platforms, with a thickness of 50mm, meeting the IMO A60 class horizontal 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 horizontal fire standard, maintaining non-fire side temperature ≤140°C for 60 minutes, providing critical area safety assurance.
Specialized processes 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 generation.
Adequate thermal insulation prevents deck condensation, while excellent sound absorption reduces equipment noise transmission.
