Rock Wool Boards
Product Description
Our rock wool boards are made from natural rocks such as basalt. They are melted at high temperatures and converted into artificial inorganic fibers using high-speed centrifugal equipment. Special adhesives and dust-proof oil are then added, followed by curing and cutting processes. Density generally ranges from 80-220 kg/m³. Common sizes include 1200×600mm and 1200×1000mm, with thicknesses of 30mm, 50mm, 75mm, and 100mm available. Custom sizes are also available.
Product Features:
Lightweight and low thermal conductivity provide excellent insulation, effectively reducing energy consumption. With an A1 fire rating, it does not burn, produce smoke, or generate harmful gases in a fire, and is dimensionally stable and will not deform. Chemically stable, neutral or slightly alkaline, it is non-corrosive to metals and contains no harmful substances, making it safe and environmentally friendly. It also offers excellent sound absorption and noise reduction properties, reducing noise transmission.
Technical parameters:
Thermal conductivity ≤ 0.035W/m·K (70±5℃), fire resistance is non-flammable Class A, applicable temperature range can reach -240℃-650℃, moisture resistance ≥95%.
