Products Description

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 feature of the rock wool board

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.
