ROCKWOOL® Technical Insulation

Why ROCKWOOL® Stone Wool for Heavy-Duty Applications?

ROCKWOOL® stone wool offers unique material properties that are essential for the most demanding industrial and maritime environments:

• 🔥 Unrivalled Fire Safety: Our systems are non-combustible (Euroclass A1) and withstand temperatures above 1,000 °C. They fully comply with the strict IMO regulations (FTP Code) for shipping and with severe hydrocarbon fire curves in the process industry.
• 🌡️ Thermal Efficiency at Extreme Temperatures: Minimal thermal conductivity at temperatures up to 650 °C. This translates directly into maximum energy savings, lower CO₂ emissions and stable process control.
• 🔇 Superior Acoustic Insulation: Noise from machinery, turbines, compressors and exhaust systems is drastically reduced, creating a safer and quieter working and living environment on board and on the shop floor.
• 💧 Advanced Corrosion Prevention (CUI): Our industrial products are equipped with water-repellent technologies (such as the innovative WR-Tech™) to effectively minimise the risk of Corrosion Under Insulation (CUI).
• ⚓ Vibration & Dimensional Stability: Mechanical vibration on ships or in plants has no effect on the structure of our stone wool. The material does not shrink or sag and retains its insulation value throughout the entire service life of the installation.

Our Specialised Product Range

Our portfolio is divided into two focused product lines, specifically designed and certified for your sector:

🚢 SeaRox® – Marine & Offshore Insulation

The SeaRox® line provides certified thermal, acoustic and fire-safe insulation for shipbuilding, marine and offshore structures.

• SeaRox® SL (Slabs): Rigid and semi-rigid insulation slabs (such as the widely used SeaRox® SL 970) for the structural insulation of decks, bulkheads, engine rooms and comfort cabins.
• SeaRox® WM (Wired Mats): Flexible stone wool mats on galvanised or stainless-steel mesh, ideal for insulating flanges, valves and curved structures on board.
• SeaRox® LM (Lamella Mats): High compressive-strength lamella mats for the thermal and acoustic insulation of ventilation ducts and pipework.

🏭 ProRox® – Industrial & Process Insulation

The ProRox® line is designed for the heavy process industry, petrochemicals, refineries and power plants.

• ProRox® PS (Pipe Sections): Pre-formed, concentric stone wool sections for fast, seamless and thermal-bridge-free insulation of high-temperature piping.
• ProRox® WM (Wired Mats): Robust wired mats for the thermal and acoustic insulation of industrial boilers, vessels, columns and large pipe runs.
• ProRox® SL (Slabs): High compressive-strength slabs for the thermal and fire-safe insulation of furnaces, storage-tank walls and flat industrial equipment.
