Rock Wool Sandwich Panel

Rock wool sandwich panel is a high-performance composite building material. It consists of rock wool core material and two layers of surface panels (usually color steel plates, aluminum alloy plates, or galvanized steel plates) bonded by professional adhesives. With excellent thermal insulation, fire resistance, and sound insulation, it is widely used in industrial workshops, warehouses, cold storage, prefabricated buildings, and other construction scenarios.

Core Characteristics

Superior Fire Resistance: The rock wool core is made of natural basalt melted at high temperature. It is non-combustible, does not release toxic gases when exposed to fire, and can effectively block fire spread for 4-6 hours.

Excellent Thermal & Sound Insulation: Rock wool’s porous structure enables low thermal conductivity (≤0.040 W/(m·K)), reducing energy consumption for heating and cooling. It also absorbs airborne sound and structural noise, improving indoor acoustic comfort.

High Structural Stability: The surface panels and core material form a strong composite structure. It has good load-bearing capacity, impact resistance, and is not prone to deformation, ensuring long-term use reliability.

Easy Installation & Efficiency: The panels are prefabricated with standardized sizes. They can be quickly spliced and installed on-site, greatly shortening the construction period and reducing labor costs.

Environmentally Friendly & Durable: Rock wool is free of formaldehyde and other harmful substances, meeting environmental standards. The surface panels are anti-corrosive and anti-rust, extending the product’s service life to 15-20 years.

Typical Applications

Industrial and civil buildings: Factory workshops, office buildings, residential buildings, and prefabricated houses.

Special-purpose buildings: Cold storage, clean rooms, data centers, and fire partitions.

External and internal walls: Curtain walls, exterior insulation walls, and interior partition walls.

Roofs and ceilings: Industrial warehouse roofs, stadium ceilings, and exhibition hall canopies.
