Trusted by shipowners and masters worldwide, our team ensures your vessel gets everything it needs — on time, every time.
Marine Acoustic Insulation Sheets are specialized materials designed to reduce noise and vibrations in marine environments. These sheets are typically made from high-density polymers or composite materials for durability and water resistance. They provide effective soundproofing and thermal insulation for ships and offshore structures.
Size: Typically available in sheets ranging from 1m x 1m to 2m x 4m, with thicknesses from 10mm to 100mm.
Grade: Classified based on density and acoustic performance, such as Grade A (high-performance) to Grade C (standard).
Viscosity: Not applicable for solid sheets; adhesive variants may have viscosities of 5,000–50,000 cP.
Buoyancy: Most materials are non-buoyant, with densities ranging from 30–200 kg/m³.
Material: Common materials include closed-cell foam (PVC, polyethylene), fiberglass, mineral wool, and elastomeric composites.
Acoustic Performance: Sound Transmission Loss (STL) of 20–50 dB, depending on thickness and material.
Temperature Range: -40°C to +120°C for most marine-grade materials.
Fire Resistance: Often compliant with IMO FTP Code Part 1 (non-combustible) or Part 5 (low flame spread).
Water Resistance: Hydrophobic properties with water absorption <1% by volume.
Compression Strength: 10–200 kPa, depending on material and density.
