Aluminum Foil Faced Rockwool Composite Board - Fireproof and Acoustic Insulation Panel

Products Description

FANRYN Rock Wool Board is produced 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.

Product feature of the rock wool board

Thermal & Energy Efficiency
The mineral wool matrix and reflective foil work together to significantly reduce heat transfer, cutting energy use for both heating and cooling.

Fire Safety
With an A1 non-combustible rock wool core and foil reinforcement, it ensures high fire resistance without toxic emissions, maintaining stability under extreme heat.

Acoustic Performance
The fibrous structure absorbs noise while the foil adds sound-blocking properties, improving indoor acoustic comfort.

Moisture & Corrosion Resistance
The foil acts as an effective vapour barrier, keeping the core dry to prevent mould and protect against corrosion.

Installation & Durability
Pre-cut panels with a tough foil surface allow for easy handling and installation, ensuring long-term reliability.
