Applications

Our 50mm composite rock wool wall panels serve steel-structure exterior walls, industrial plants, warehouses, cold rooms, prefab buildings and harsh-climate projects in the Middle East and South America.

Construction Optimization

Conventional problem	Our 50mm rock wool solution
Thin single-layer steel / EPS: poor sound, weak fire, poor weather	Class A fire, high sound absorption, anti-corrosion
Middle East heat / S. America humidity → noise, fire risk, peel, rust	Stable envelope, passes local inspection
Manual rework & defects	Modular assembly, faster, lower maintenance

Key Advantages

Featuring A1 non-combustible grade, great sound absorption and anti-corrosion performance. Modular installation cuts construction time, forming complete EPS-rockwool building envelope with lower leakage risk.

Customization/OEM / ODM Service

Custom panel lengths tailored to individual projects
0.3–0.8mm steel skins, full RAL color options, PE/PVDF/SMP coatings
Core density adjustable within 50–150 kg/m³
OEM & ODM customization available
SGS / BV third-party inspection and export documents supported
Small trial orders & mixed container shipments acceptable

Certifications & Compliance

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%.

Comparison: Rock Wool vs EPS vs PIR

Factor	Rock Wool	EPS	PIR
Fire rating	A1/A2 non-combustible	B / flammable	B / limited
Thermal λ	≤0.040	≈0.038–0.042	≈0.022–0.024
Sound insulation	30–50 dB (excellent)	Low	Medium
Toxic smoke	None	Yes when burned	Yes when burned
Cost	Medium–high	Low	High
Best for	Fire-safe walls	Low-budget roofs	Max insulation

Warranty

Our 10–20 year written warranty protects against factory defects such as panel delamination, core displacement and coating failure under normal use. Damages from mechanical issues or incorrect installation are not covered; claims need visual evidence, and solutions follow your contract.

FAQ

Q: Can 50mm rock wool pair with my EPS roof?

A: Yes - designed as a combined envelope; same profile family.

Q: Is 50mm enough for exterior walls?

A: For partitions and mild climates yes; for cold stores or high fire rating choose 75–120 mm.

Q: Does it pass local inspection in the Middle East / S. America?

A: Class A fire and full specs support compliance; final approval depends on local authority - we supply test reports.

Q: How can buyers verify the quality of the 50mm composite rock wool wall panel before shipment?

A: We support third-party inspection services such as SGS and BV, and provide export documents to meet international trade requirements. Product quality is guaranteed through a written warranty covering manufacturing defects under normal use, while technical documents and installation guidance help ensure proper on-site assembly.

Q: What after-sales and technical support are provided after purchase?

A: We provide online technical support, installation guides, construction drawings, detailing documents, standardized installation steps, construction precautions and remote guidance for on-site assembly. Spare accessories are available, and quality-related claims are handled within 24 hours based on photo or video evidence and the contract terms.
