High Quality Thermal Insulation Color Steel Rock Wool Sandwich Panel Wall Sandwich Panel Price Exterior Sandwich Wall Panel

1. Exceptional Thermal Insulation for Energy Efficiency

• Low thermal conductivity of rock wool core: The panel’s core is made of high-density rock wool (typically 100 - 160 kg/m³) with a thermal conductivity as low as 0.036 - 0.044 W/(m·K). This creates a tight thermal barrier for exterior walls, effectively reducing heat transfer between indoor and outdoor spaces.

• Energy savings in all climates: In cold regions, it minimizes heat loss to maintain indoor warmth; in hot regions, it blocks external heat ingress to reduce air conditioning loads. This translates to 15 - 30% lower HVAC energy consumption for buildings, aligning with global energy-saving standards (e.g., LEED, BREEAM).

• No thermal bridges: The continuous sandwich structure (color steel + rock wool core + color steel) eliminates gaps or weak points that cause "thermal bridges" (high-heat-loss areas), ensuring uniform insulation across the entire exterior wall.

2. Top-Tier Fire Safety (Inherent Non-Combustibility)

• Class A fire rating: Rock wool is derived from natural rocks (e.g., basalt) melted at 1,500+ °C, making it an inherently non-combustible material (meets GB 8624-2012 Class A or EN 13501-1 Class A1 standards). It does not burn, melt, or release toxic gases (e.g., formaldehyde, cyanide) when exposed to fire.

• Fire barrier effect: In case of fire, the rock wool core forms a stable, heat-resistant layer that slows flame spread and protects the building’s internal structure. This is critical for exterior walls, as it reduces the risk of fire spreading between floors or adjacent buildings.

• Long-term fire performance stability: Unlike organic insulation materials (e.g., EPS), rock wool does not degrade or lose fire resistance over time, ensuring consistent safety for the building’s lifespan.

3. Superior Weather Resistance for Exterior Durability

• High-performance color steel outer layer: The panel’s surface uses 0.3 - 0.8 mm thick galvanized or galvalume steel sheets coated with premium finishes (e.g., PVDF, SMP, or FEVE coatings):

• UV resistance: PVDF coatings (common in high-quality panels) resist ultraviolet radiation, preventing color fading, chalking, or coating peeling even after decades of outdoor exposure.

• Waterproof & corrosion resistance: The dense coating and galvanized steel base repel rain, snow, and moisture; they also resist salt spray (ideal for coastal areas) and mild chemical corrosion (e.g., urban smog), avoiding rust or structural damage.

• Moisture-resistant rock wool core: High-quality panels use water-repellent rock wool (water absorption rate < 5% by volume) that does not absorb moisture easily. This prevents mold growth, insulation degradation, or steel sheet rust caused by dampness—critical for exterior walls exposed to rain, dew, or humid air.

• Wind & impact resistance: The rigid composite structure (color steel + rock wool) withstands strong winds (up to 150 km/h, depending on panel thickness) and minor impacts (e.g., hail, debris), maintaining the exterior wall’s integrity in harsh weather.

4. Excellent Sound Insulation for Indoor Comfort

• Porous structure for noise absorption: Rock wool’s open, fibrous structure traps and dissipates sound waves, especially effective at absorbing airborne noise (e.g., traffic, construction, or street chatter) and impact noise (e.g., rain on the wall, wind vibration).

• Significant noise reduction: For standard 50 - 100 mm thick panels, noise reduction reaches 25 - 40 dB—far better than single-layer materials (e.g., brick walls, plain steel sheets). This creates a quieter indoor environment, even for buildings located in busy urban or high-traffic areas.

• Sound insulation stability: Unlike foam-based insulators, rock wool does not compress or degrade over time, ensuring consistent soundproofing performance for the panel’s entire service life.
