Factory Direct CE Certified Aluminum Foil Rockwool Board
Fireproof, waterproof insulation board with foil facing for superior thermal and acoustic performance.
Product Overview
From volcanic rock to high-performance insulation.
FANRYN Rock Wool Board begins with basalt and dolomitic limestone—melted at over 1450°C and spun into fine, inorganic fibers. Bonded with thermosetting resin, the result is a rigid core that naturally resists fire, moisture, and dimensional shift.
The foil facing does more than cover.
Engineered with a puncture-resistant aluminum foil laminate, it serves as both a radiant barrier—reflecting heat to maximize thermal efficiency—and a vapor barrier, protecting against moisture, mold, and corrosion. One facing, two functions built into every board.
For systems that demand more.
Designed for HVAC ductwork, roofing, wall linings, and industrial applications where thermal and acoustic control is critical.
Key Features
- Thermal & Energy Efficiency: Mineral wool core and reflective foil work together to minimize thermal transfer, reducing heating and cooling costs
- Fire Safety: A1 non-combustible rating with zero toxic emissions and stable performance under extreme heat
- Acoustic Performance: Fibrous core absorbs sound while foil adds blocking layer for superior noise control
- Moisture & Corrosion Resistance: Foil facing acts as continuous vapor barrier, preventing mold and corrosion
- Installation & Durability: Pre-cut panels with tough foil surface for faster installation and decades of reliable performance
