Acoustic Insulation Soundproof Rock Wool Board For Marine Sound Insulation 47dB 45kg/M3
Our acoustic insulation rock wool is engineered for cabins with strict acoustic requirements on vessels and offshore platforms, with a density of 45kg/m³ and a certified sound insulation rating of 47dB. Featuring optimized fiber structure, it delivers high-efficiency sound insulation while remaining lightweight, effectively blocking conversation noise, equipment noise, and footstep sounds between cabins. With Class A non-combustible fire performance and excellent thermal insulation, it is ideal for captain's quarters, VIP cabins, conference rooms, and hospital ship wards.
- Captain's quarters, senior officer cabins
- VIP cabins, suites on yachts and cruise vessels
- Conference rooms, cinemas, entertainment rooms
- Hospital ship wards, operating rooms
- Cabins requiring high sound insulation
