Compliance & Type Approval Process

To ensure compliance with stringent marine safety codes, our ceiling tiles undergo rigorous ‌fire resistance testing‌ at accredited Fire Test Centers. Upon successful testing, they receive ‌type approval from major classification societies‌ (such as ABS, DNV, LR). This pre-certification process guarantees that the products delivered to the shipyard meet the required ‌fire rating (e.g., B-0, B-15)‌ for your project, streamlining the installation and inspection phases.
