Products Description
FANRYN Rock Wool Board is manufactured from natural rocks such as basalt and limestone. The rocks are melted in a cupola at temperatures exceeding 1450°C, and the molten lava is fiberized by a high-speed spinner. These inorganic fibers are then bonded using a thermosetting resin to form a stable and resilient wool matrix.
To enhance performance for specific applications, the board is laminated with a reinforced aluminium foil facing on one side. This durable foil layer acts as a radiant barrier, effectively reflecting heat to significantly improve overall thermal insulation efficiency. Simultaneously, it serves as a premium vapour barrier, effectively resisting moisture penetration to protect the integrity of the insulation core and prevent mould growth. The clean, robust surface also simplifies handling and installation, making it an ideal, high-performance solution for HVAC duct insulation, roofing systems, and wall linings.
Product feature of the rock wool board
Thermal & Energy Efficiency
Combining a dense mineral wool core with reflective aluminum foil, the product provides superior thermal insulation, significantly reducing heat transfer and lowering building energy use.
Fire Safety & Stability
With a non-combustible rock wool core (Class A1, no toxic emissions) and foil‑reinforced structure, the board delivers reliable fire protection and maintains stability even under high temperatures.
Acoustic Performance
The fibrous wool core absorbs noise, while the foil layer further blocks sound transmission, together enhancing acoustic comfort indoors.
Moisture & Corrosion Resistance
The aluminum foil facing serves as an effective vapor barrier, keeping the wool core dry, preventing mold, and protecting against corrosion for long‑term durability.
Durable & Easy to Install
Pre‑cut to standard sizes with a tough foil surface, the boards are simple to handle and install, resistant to site damage, and designed for lasting performance.
