rockwool sandwich wall panel
1. Excellent Fire Resistance (Core Advantage)
Rockwool sandwich wall panels are non-combustible and can achieve high fire ratings (A1 / A2), making them ideal for:
Industrial factories
Chemical plants
Power stations
High-risk buildings
When used with a sandwich panel roof, they form a complete fire-resistant building envelope.
2. Superior Thermal & Acoustic Insulation
Rockwool provides:
Excellent thermal insulation
Effective sound absorption
This is especially important for:
Industrial noise control
Temperature-sensitive environments
3. High Structural Strength
The fiber structure of rockwool combined with metal sheets ensures:
Strong load-bearing capacity
Wind resistance
Structural stability
4. Moisture Resistance & Breathability
Rockwool panels offer:
Good vapor permeability
Resistance to moisture accumulation
This helps maintain long-term insulation performance.
5. Long Service Life
With corrosion-resistant metal surfaces and stable mineral wool core, panels can last over 20–30 years with minimal maintenance.
6. Environmental & Non-Toxic Material
Rockwool is:
Environmentally friendly
Non-toxic
Recyclable
Suitable for projects with environmental requirements.
7. Flexible Customization for Projects
We provide OEM/ODM services:
Panel thickness (50mm–200mm)
Density customization
Surface coating & color
Length and profile customization
Project-based solutions
8. Ideal for High-Safety B2B Projects
Compared with EPS or PU panels, rockwool sandwich wall panels are the preferred choice for:
Fire-regulated projects
Government buildings
Industrial safety facilities
Product Details
