Customization

Our Mineral Wool Composite Panels feature high-density basalt rock wool core (100 kg/m³ for 75mm wall version), Class A non-combustible and dimensionally stable, paired with 0.3–0.8mm anti-aging, weather-resistant metal skins. Full RAL colors and custom profiles, steel gauges & lengths are available, with optional upgrades for coastal humid environments.

Key Advantages

Our panels have EN 13501-1 Class A1 mineral wool core with thermal conductivity of 0.035–0.040 W/(m·K). They deliver 30–50 dB sound reduction, high compressive strength and salt-spray resistant metal facings. Quick tongue-and-groove installation saves over 60% construction time. Eco-friendly basalt material and full customization on thickness, density and RAL colors are available.

Application Scenarios

Panel thickness and density can be customized to suit diverse industries. Below are recommended configurations for typical applications:

Application Scenario	Reference Spec.	Reasons
Residential & Office (Mild Climate)	Thickness: 50mm; Density: 120kg/m3	For residential and office buildings in temperate climate zones, the 50mm panel with 120kg/m³ density delivers the optimal balance of thermal insulation and cost efficiency.
Cold Region Buildings	Thickness: 120-200mm Density: 120-150kg/m3	In cold regions including Russia and Mongolia (extreme temperature down to -30°C), 120–200mm panels at 120–150 kg/m³ density are suggested for reliable thermal insulation.
Large Public Buildings (Stations, Airports)	Thickness: 50-100mm Density: 160-180kg/m3	Large projects like high-speed rail stations and airports adopt 50–100mm high-strength panels (160–180 kg/m³ density), achieving optimal balance of load capacity, moisture-proof property and thermal insulation.
Industrial Plants & Warehouses	Thickness: 75-150mm Density: 80-120kg/m3	Steel workshops & logistics warehouses: 75–150mm panels recommended for balanced insulation, fire performance and cost management.
Cold Storage & Cold Chain	Thickness: 100-200mm Density: 100-150kg/m3	Cold storage & cold-chain facilities need thick panels with high insulation: 100–200mm panels with high-density core are suggested.
