Rock Wool Slab with Aluminum Foil Vapor Barrier for High Temp HVAC Duct Insulation Class A Fire Rating

FANRYN rock wool boards are produced from natural basalt and limestone, which are melted at ultra-high temperatures exceeding 1450℃ in a specialized furnace. The molten material is then fiberized through advanced centrifugal spinning technology, forming an intricate matrix of mineral wool. These fibres are subsequently bonded with a high-performance thermosetting resin to create a durable and dimensionally stable product. Finally, the material is precision-cut into standardized panels and rolls, ensuring consistency and ease of handling across a wide range of insulation applications.

• Outstanding Thermal Performance: Effectively minimizes heat flow to maintain consistent interior temperatures, significantly lowering energy consumption and costs.
• Exceptional Fire Resistance: Rated Class A fireproof and entirely non-combustible, capable of resisting extreme temperatures over 1000°C for enhanced structural safety.
• Superior Sound Absorption: Effectively absorbs airborne and impact noise, greatly reducing sound transmission to ensure quieter, more comfortable living and working spaces.
• High Resistance to Moisture & Corrosion: Effectively repels water and inhibits condensation formation, preventing mold growth, corrosion, and long-term material breakdown.
• Environmentally Responsible: Manufactured using natural volcanic rock and recycled content, supporting sustainable construction and circular economy initiatives.
• Energy Saving & Emission Reduction: Dramatically improves a building's energy efficiency, leading to measurable reductions in carbon emissions from heating and cooling systems.
