Product Overview
Rock Wool Sandwich Wall Panel is a non-combustible industrial wall cladding system designed for steel structure buildings requiring high fire safety, thermal insulation, and acoustic performance.
It is composed of:
- Double metal facings (PPGI / PPGL / Aluminum)
- High-density rock wool insulation core
This system is widely used in EPC industrial projects, warehouses, factories, and fire-rated building systems, especially where compliance with international fire safety standards is required.

Core Advantages
Fire Safety - A1 Non-Combustible
Inorganic Mineral Core: Derived from natural volcanic rock; strictly non-combustible.
Zero Hazards: Generates no burning droplets, zero smoke, and zero toxic gases under extreme heat.
Fire Resistance Rating: Offers 60 to 180 minutes of structural integrity.
Project Safety: The ultimate choice for building fire compartment walls and emergency escape zones.
Thermal Insulation and Energy Efficiency
Low Thermal Conductivity: Rated at 0.037 to 0.043 W/m.K, significantly lowering HVAC energy consumption.
Thermal Stability: Minimizes heat transfer to maintain predictable, stable indoor temperatures for sensitive manufacturing or storage.
Acoustic Performance and Noise Control
Sound Attenuation: Reduces industrial airborne noise by up to 40 dB.
Compliance Ready: Enhances workplace safety and regulatory compliance in high-noise environments like manufacturing workshops and transport hubs.
Structural Stability and Long-Term Durability
High-Density Matrix: Structural rock wool core resists warping and deformation under extreme temperature fluctuations.
Corrosion and Moisture Resistance: Designed to withstand humid environment degradation.
Extended Lifespan: Built for a service life of 25 to 50 years, lowering lifecycle maintenance costs.
Modular Fast Installation
Prefabricated Modules: Precision-engineered modules arrive ready for immediate installation.
High Compatibility: Integrates seamlessly with all standard steel structure framing.
Time Savings: Reduces on-site installation schedules by 30% to 50% compared to traditional wet construction.
Diversified Application Fields
- Industrial mega-factories and manufacturing workshops
- Logistics hubs, distribution centers and structural warehouses
- Fire-rated internal partition walls and cleanrooms (Electronics/Pharmaceuticals)
- Aviation infrastructure (Airports and transportation hubs)
- Power plants, chemical plants and energy facilities

FAQ
Q: What is the fire rating of rock wool sandwich wall panels?
A: Rock wool sandwich panels are classified as A1 non-combustible material, meaning they do not burn, do not support combustion, and do not produce toxic smoke. Fire resistance can reach 1–3 hours depending on thickness and system design.
Q: What is the difference between rock wool panels and PU sandwich panels?
A: Rock wool panels provide superior fire safety and acoustic insulation, while PU panels offer better thermal insulation but are more flammable. Rock wool is the preferred choice for fire-regulated industrial buildings and EPC projects.
Q: Can rock wool sandwich panels be used in cold storage buildings?
A: Yes. Rock wool panels provide stable thermal insulation and can be used in cold storage, refrigeration facilities, and temperature-controlled warehouses, especially where fire safety is also required.
Q: What panel thickness should I choose?
A: Common thickness options are 50mm to 200mm.
50–75mm: interior partitions
100mm: standard industrial walls
120–200mm: high fire resistance and cold climate projects
We can recommend thickness based on your project requirements.
Q: Do you provide custom sizes and colors?
A: Yes. We offer full customization for:
Panel thickness
Steel sheet color (RAL system)
Effective width
Surface coating (PE / PVDF / SMP)
Q: What is the service life of rock wool sandwich panels?
A: Under normal installation and maintenance conditions, the service life is 25–50 years, depending on environmental conditions and coating protection.
Q: Are your panels suitable for export and international standards?
A: Yes. Our panels are widely used in global projects and can be supplied with EN, ASTM, and SGS test reports upon request, suitable for EPC and international tender projects.
