FAQ

Q1: What fire rating do your Rock Wool Sandwich Panel Wall have?

A: The mineral wool core holds EN 13501-1 Class A1 non-combustible certification, complying with stringent global industrial fire safety requirements.

Q2: How about thermal and acoustic performance?

A: Thermal conductivity reaches 0.035–0.040 W/(m·K). The 75mm panel lowers indoor temperature by 5–8°C and reduces energy cost by 15–20%. It achieves 30–50 dB sound reduction for acoustic comfort.

Q3: What are the benefits of prefabricated installation?

A: Tongue & groove / hidden clip connections allow 300–500 m² installation per team daily, shortening construction time by over 60%.

Q4: Are the panels suitable for harsh environments?

A: Yes. Galvanized or color-coated metal facings withstand high heat, high humidity and coastal salt spray. They are lightweight with 85–105 kPa compressive strength, fit for large-span steel structures.

Q5: Are the panels eco-friendly and customizable?

A: Made from natural basalt, CFC/HCFC-free and recyclable to meet green building standards. RAL colors, thickness (50–200mm), core density and edge connections can all be customized.
