Durable and Multifunctional Rock Wool Boards for Marine Applications

Rock wool board is an inorganic thermal insulation material made from natural rocks such as basalt and diabase as the main raw materials, which are melted at high temperature, shaped into fibration, and then pressed. Rock wool boards have notable advantages, widely preferred in diverse marine applications.

Core Performance

Class A non-combustible with fire resistance rating of 1-4 hours, complying with SOLAS fire safety standards
Low thermal conductivity (0.035-0.045W/(m*K)) effectively blocks heat transfer
Hydrophobic treatment provides resistance to moisture and salt spray corrosion
Excellent compressive and flexural strength withstands ship vibration
Maintains performance in high-humidity, high-salt marine environments

Key Advantages

Superior fire protection reduces risk of casualties and property damage
Combines thermal insulation, fire resistance and sound insulation in one material
Simplifies construction process by reducing material types needed
Service life exceeds 20 years, reducing maintenance costs
Complies with IMO regulations and classification society standards (LR, ABS, etc.)

Marine Applications

Thermal insulation for engine rooms, accommodation cabins, and cargo holds
Fire-resistant bulkheads and deck coverings for zone separation
Noise reduction in equipment areas like engine and pump rooms
Insulation for steam pipes and exhaust systems
Maintains optimal temperatures while preventing heat transfer between compartments

Material Comparison for Shipbuilding Applications

Material	Core Performance	Main Advantages	Marine Applications
Rock Wool Board	Class A non-combustible, fire resistance 1-4 hours; thermal conductivity 0.035-0.045W/(m*K); salt spray resistant; density 80-150kg/m³	High fire safety, combined thermal/sound insulation; marine environment adaptability; 15+ year service life	Fire-resistant bulkheads, cabin insulation, equipment room soundproofing, pipeline insulation
Glass Wool	Class A non-combustible, fire resistance 0.5-2 hours; thermal conductivity 0.036-0.044W/(m*K); good flexibility; moderate moisture resistance	Excellent sound insulation, easy installation; lower cost than rock wool	Ventilation duct soundproofing, non-high-temperature area insulation
Aluminum Silicate Wool	Class A non-combustible, fire resistance 2-5 hours; withstands ≥600℃; thermal conductivity 0.030-0.040W/(m*K)	Ultra-high-temperature performance, exceptional fire resistance	Exhaust pipes and high-temperature equipment insulation
Polyurethane Foam	Class B1 flame-retardant, fire resistance ≤1 hour; thermal conductivity 0.020-0.025W/(m*K); good water resistance	High insulation efficiency, lightweight (30-50kg/m³)	Low-temperature refrigerated cabins (requires additional fireproof layer)
Mineral Wool Board	Class A non-combustible, fire resistance 1-3 hours; thermal conductivity 0.038-0.046W/(m*K)	Cost-effective, meets basic insulation/fire resistance needs	Ordinary cargo hold insulation, non-critical area fire separation
