Fireproof and Acoustic Insulation Aluminum Foil Faced Rockwool Composite Board with Low Water Absorption

FANRYN Rock Wool Board is manufactured from naturally sourced volcanic rock, primarily basalt and dolomitic limestone. These raw materials are superheated to a molten state above 1450°C in a cupola furnace, then transformed into fine, inorganic fibers by a high-speed centrifugal spinner. The fibers are bonded with a thermosetting resin to form a dimensionally stable, resilient, and fire-resistant wool substrate.

For enhanced functional performance, the board is factory-laminated on one side with a reinforced, puncture-resistant aluminium foil facing. This facing provides a durable radiant barrier that reflects thermal energy, significantly boosting overall thermal insulation effectiveness. It also acts as an advanced vapour barrier, blocking moisture ingress to maintain the insulation's performance over time and prevent mould or corrosion. The smooth, robust surface offers improved handling and ease of installation, making it an ideal high-performance solution for HVAC ductwork, roofing assemblies, wall lining systems, and industrial thermal-acoustic applications.
