CE Certificated Insulation Material Rockwool Board with Aluminum Foil Facing
The FANRYN Rock Wool Board is engineered from naturally sourced volcanic rock—primarily basalt and dolomitic limestone. These materials are melted at over 1450°C in a cupola furnace and spun into fine, inorganic fibers using high-speed centrifugal technology. The fibers are then bonded with a thermosetting resin, resulting in a rigid, fire-resistant, and dimensionally stable insulation core.
To maximize functional performance, the board is factory-laminated with a reinforced, puncture-resistant aluminum foil facing. This facing acts as both a radiant barrier—reflecting heat to enhance thermal efficiency—and a high-performance vapor barrier, protecting against moisture ingress, mold, and corrosion. The result is a durable, easy-to-handle solution ideal for HVAC ductwork, roofing, wall linings, and industrial applications requiring superior thermal and acoustic control.
Product Features
- Thermal & Energy Efficiency: The mineral wool and reflective foil work together to minimize heat transfer, delivering significant energy savings for heating and cooling.
- Fire Safety: With an A1 non-combustible core and foil reinforcement, it offers high fire resistance without toxic emissions—remaining stable even under extreme heat.
- Acoustic Performance: Its fibrous structure absorbs noise while the foil adds sound-blocking properties, ensuring superior indoor acoustic comfort.
- Moisture & Corrosion Resistance: The foil acts as a reliable vapor barrier, keeping the core dry to prevent mold and corrosion.
- Installation & Durability: Pre-cut panels with a tough foil surface enable quick installation and ensure long-term reliability.
