Insulation Rock Wool Material
Rock wool products are made of high-quality natural basalt ore and dolomite as the main raw materials. They are melted at high temperature, spun into fibers by high-speed centrifugal spinning, and then heat-cured and shaped using advanced production technology and a small amount of binder. The outer surface can be covered with glass fiber cloth or aluminum foil glass fiber cloth according to customer needs. The material varieties include plates, profiles, and tube shells.
Overview
Key Advantages
• A60/A30 Fire Rating: Fully compliant with marine fire codes such as the 2010 FTP Code.
• Superior Thermal Insulation: Thermal conductivity as low as ≤0.041W/m·k, energy efficient.
• Marine-Specific: Suitable for decks, bulkheads, and piping, providing composite rock wool board/floor floor core material solutions.
Insulation rock wool material is mainly used for fireproofing and heat insulation of ship decks and bulkheads, pipelines, and equipment, and can also be used as a sandwich material for composite rock wool sidings/floating floors.
Marine Class A fireproof rock wool insulation material
Our rock wool products use high-quality natural basalt as the main raw material. After high-temperature melting, centrifugal fiberization, and curing, they are Class A non-combustible fireproof and thermal insulation materials specifically designed for shipbuilding and marine engineering.
Core Advantages: The products fully meet the requirements of the 2010 International Fire Resistance Testing Procedures Application Code (FTP Code), providing A60 and A30 fire-resistant partition solutions. They also possess excellent thermal insulation and sound insulation properties, are asbestos-free, and are safe and environmentally friendly.
Main Applications: Suitable for fireproofing of ship decks and bulkheads, thermal insulation of pipes and equipment, and can also be used as a high-quality core material for composite rock wool boards and floating floors.
