Durable And Multifunctional Rock Wool Boards Extensively Applied In Marine Manufacturing
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 applications.
Core Performance
Rock wool boards have excellent properties in shipbuilding. First of all, they are Class A non-combustible with a fire resistance rating of 1-4 hours, complying with the fire safety standards of SOLAS in IMO. Rock wool boards also have a low thermal conductivity, which can effectively block heat transfer; after hydrophobic treatment, they are resistant to moisture and salt spray corrosion, adapting to the high-humidity and high-salt marine environment. Besides, our products have certain compressive and flexural strength, not easily damaged by ship vibration.
Oustanding Advantages
Rock wool boards have prominent advantages in shipbuilding. The non-combustible property and high fire resistance limit provide key guarantees for ship fire prevention and control, reducing the risk of casualties and property losses. Besides, they can meet the needs of thermal insulation, fire resistance and sound insulation at the same time, reducing the types of materials and simplifying the construction process. They are resistant to salt spray and moisture, with a service life of more than 20 years, which can reduce ship maintenance costs. And our products comply with the regulations of the International Maritime Organization and shipbuilding standards of various countries (such as those of classification societies like LR and ABS), facilitating ship survey and certification.
Multiple Applications
Rock wool boards find extensive applications in shipbuilding. They are utilized in the wall, ceiling and floor interlayers of engine rooms, accommodation cabins, cargo holds and other areas to achieve cabin thermal insulation, reducing heat transfer to maintain optimal temperatures—for instance, mitigating the impact of high temperatures in engine rooms on adjacent accommodation cabins. As a core material for fire-resistant bulkheads and deck coverings, they meet the fire separation requirements for different zones (such as engine rooms and passenger cabins) as specified in ship regulations, retarding the spread of fire. Applied in the enclosure structures of equipment areas like engine rooms and pump rooms, they absorb noise from mechanical vibrations, lowering in-cabin noise pollution. Additionally, they can wrap around ship steam pipes, exhaust pipes and the like, reducing heat loss and preventing potential safety hazards caused by high surface temperatures.
Comparison between Rock Wool Board and Other Materials in Shipbuilding
| Material | Core Performance | Main Advantages | Main Applications in Shipbuilding |
| Rock Wool Board | Class A non-combustible, fire resistance rating 1-4 hours; thermal conductivity 0.035-0.045W/(m·K); salt spray and moisture resistant; density 80-150kg/m³ | High fire safety, combined thermal insulation and sound insulation; adaptable to harsh marine environments; long service life (over 15 years) | Fire-resistant bulkheads, cabin insulation layers, sound insulation in equipment rooms, pipeline insulation |
| Glass Wool | Class A non-combustible, fire resistance rating 0.5-2 hours; thermal conductivity 0.036-0.044W/(m·K); good flexibility; moderate moisture resistance | Excellent sound insulation, easy to cut and install; slightly lower cost than rock wool boards | Sound insulation for ventilation ducts, insulation in non-high-temperature areas |
| Aluminum Silicate Wool | Class A non-combustible, fire resistance rating 2-5 hours; high temperature resistance ≥600℃; thermal conductivity 0.030-0.040W/(m·K) | Strong applicability in ultra-high-temperature environments, outstanding fire resistance | Insulation for exhaust pipes and outer layers of high-temperature equipment |
| Polyurethane Foam | Class B1 flame-retardant, fire resistance rating ≤1 hour; thermal conductivity 0.020-0.025W/(m·K); good water resistance | High insulation efficiency, lightweight (density 30-50kg/m³) | Insulation for low-temperature refrigerated cabins (requires matching fireproof layer) |
| Mineral Wool Board | Class A non-combustible, fire resistance rating 1-3 hours; thermal conductivity 0.038-0.046W/(m·K); low price | Cost-effective, meeting basic insulation and fire resistance requirements | Insulation for ordinary cargo holds, fire separation in non-critical areas |
