Applications

Mineral Wool Sandwich Wall Panel suit multiple scenarios. For steel factories and warehouses, they deliver Class A fire safety and rapid modular assembly. Ideal for commercial complexes, hospitals, schools and offices thanks to non-combustible performance, acoustic comfort and zero toxic smoke. They also serve as reliable thermal & fire-safe envelopes for cold storage projects.

Key Advantages

Class A fire resistance with NO toxic smoke when exposed to heat
Porous fiber - excellent thermal insulation & noise reduction (30–50 dB)
Lightweight - reduces foundation load, yet reliable compression & impact resistance
Anti-corrosion facing adapts to harsh environments; service life 10–15 years*
Modular design - fast installation, lower overall project cost

Project References

This 3,800 m² electronics workshop in Mexico adopted our 75 mm rock wool wall panels. It achieves 30 dB sound insulation with 60% shorter construction time. Installation finished in only 12 days, and panels passed fire inspection at the first trial. Compared with traditional walls, the system ensures reliable fire & acoustic performance and cuts total cost by 28%.

After-sales & Global Delivery

We deliver one-stop customization for panel thickness, length and RAL colors. Our pre-sale technical team provides tailored solutions. Standardized production guarantees consistent quality, with flexible shipment from Dalian port and reliable after-sales installation guidance.

Comparison with Other Cores

Comparison of core insulation materials: EPS (B1/B2 fire rating, low cost, releases toxic fumes when burned), PIR (B/C rating, premium thermal performance, high cost). Our mineral wool panels achieve A1 non-combustible grade with no toxic smoke. It delivers outstanding sound insulation at moderate cost, with reliable thermal performance.

Warranty

We issue a 10–20 year written warranty against delamination, core displacement and coating defects. It excludes mechanical damage and faulty installation. Submit photo or video proof for replacement or compensation as agreed in contract.
