FAQ
1. What is a Rock Wool Sandwich Panel?
A Rock Wool Sandwich Panel is a composite building material made of two metal sheets bonded with a high-density mineral wool core, designed for fire resistance, thermal insulation, and soundproofing.
2. What is the fire rating of rock wool panels?
Rock wool panels are classified as A1 non-combustible, meaning they provide the highest level of fire protection and do not contribute to fire spread.
3. What thickness should I choose?
50–75 mm → Standard wall insulation
100–150 mm → Industrial & commercial buildings
150–200 mm → Cold storage / high insulation demand
4. Are rock wool sandwich panels waterproof?
The panels are water-resistant, but not fully waterproof. Proper sealing and installation are required to ensure long-term performance.
5. Can the panel size be customized?
Yes, we support full customization, including:
Length (up to 12 meters or more)
Thickness
Steel sheet type & coating
Joint system design
6. What steel materials are available?
We offer multiple surface options:
PPGI (Pre-painted Galvanized Steel)
GI (Galvanized Steel)
Stainless Steel
Aluminum Sheet
7. What is the lifespan of rock wool sandwich panels?
Typically 15–30 years, depending on environment, coating type, and maintenance.
8. Are these panels suitable for roofing?
Yes, we provide both wall panels and roof panels, with different profiles and connection systems.
9. Do you provide certifications?
Yes, we can provide:
SGS / BV / TUV inspection reports
ISO certification
Fire resistance test reports (A1 standard)
10. What industries use rock wool sandwich panels?
Widely used in:
Steel structure buildings
Warehouses & factories
Cold storage facilities
Clean rooms & pharmaceutical plants
Power plants & petrochemical projects
11. What is the difference between rock wool and PU sandwich panels?
Rock Wool Panel → Better fire resistance (A1)
PU Panel → Better thermal insulation but lower fire rating
12. How are the panels installed?
Panels are installed using:
Hidden screw systems or overlap joints
Steel structure framing
Sealing materials for insulation and waterproofing
