Marine Insulation Application Example – A60 Fire & Acoustic Insulation

As shown in the image above, an A60 fire-rated marine insulation system has been applied within a ship’s interior space. This application has been engineered to simultaneously ensure fire safety, thermal control, and acoustic performance.

The system used in this project includes:

• Aluminum foil-faced rock wool insulation panels

• Steel structural fixing system

• IMO & SOLAS compliant A60 insulation layer

• Optimized acoustic and thermal performance

Which System Is Commonly Used?

• Marine rock wool with a density of 100–140 kg/m³

• Foil-faced fire-resistant insulation panels

• Mechanical fixing pin system

• A60 application for bulkheads and ceilings

This system provides:

✔ 60-minute fire resistance
✔ Thermal transfer control
✔ Noise insulation against machinery-induced vibrations
✔ Moisture and condensation control

​

The Role of Foil Cladding in Ship Insulation Systems

The aluminum foil cladding shown in the image:

• Acts as a vapor barrier

• Prevents moisture transmission

• Reduces the risk of condensation

• Improves HVAC efficiency

This system is particularly critical for:

• Areas above engine rooms

• Spaces below living quarters

• Technical compartments

​

Where Is A60 Fire-Rated Insulation Required in Ships?

According to international maritime standards, A60 insulation is mandatory in critical areas such as:

• Between engine rooms and accommodation spaces

• Technical compartments

• Fire divisions

This application has been carried out in compliance with classification society rules and SOLAS requirements.
