1. Product Overview
Rock wool composite panels are multifunctional building boards made from natural basalt fibers, high-temperature melted and formed, then laminated with high-strength metal panels or inorganic facing panels. They integrate four core properties: fire resistance, thermal insulation, soundproofing, and weather durability, widely applied in high-standard safety protection scenarios for industrial and civil buildings.

4. Key Advantages
（1）Efficient Thermal Insulation
The composite panel’s thermal conductivity is as low as 0.04 W/(m·K), significantly reducing heat transfer. It helps maintain stable indoor temperatures, reduces HVAC energy consumption, and supports building energy savings.
（2）Excellent Fire Resistance
The rock wool core is non-combustible and meets A1 fire rating standards, resisting flames without producing toxic smoke. Ideal for high fire-safety areas like high-rise buildings, industrial plants, and data centers.
（3）Sound Absorption and Noise Reduction
Its porous structure effectively absorbs and blocks sound waves, creating a quiet and comfortable indoor environment in schools, hospitals, offices, and industrial facilities.
（4）Moisture and Durability Resistance
The protective panel ensures waterproof and moisture-proof performance, preventing core damage and extending service life, even in humid environments.
（5）Easy Installation
Available in multiple specifications, lightweight yet strong, and compatible with dedicated connectors. Installation is simplified, saving labor and time, suitable for new construction, renovation, and expansion projects.
5. Application Scenarios
■ Buildings: External wall insulation, roof sandwich panels, fire partitions, cold storage insulation.
■ Industrial: Pipe and equipment insulation, workshop soundproofing, cleanroom walls.
■ Transport Facilities: Ship bulkheads, high-speed train cabin sound insulation, tunnel fire protection layers.

8. FAQ
Q1: Will the composite panel absorb water?
A1: The core is hydrophobic (moisture absorption ≤1%) and paired with sealed panels ensures long-term moisture resistance. Extra waterproofing is recommended in humid areas.
Q2: Are special tools required for installation?
A2: Panels can be cut and drilled; use anchor bolts or metal frameworks, and seal joints with dedicated sealant.
Q3: What is the service life of the composite panel?
A3: ≥25 years under normal conditions; regular inspection of joint seals is recommended.
