1 Product Parameters

2 Product Features

With our CE-certified 75mm Rock Wool Wall Sandwich Panel, a pinnacle of safety and efficiency. Engineered with a non-combustible rock wool core, it boasts Class A fire resistance, enduring over 4 hours to shield buildings from fire hazards. With a density of 80-150 kg/m³ (typically 120 kg/m³) and compressive strength exceeding 150 kPa, paired with dual steel layers, it withstands extreme weather effortlessly. The panel’s thermal conductivity of ≤0.043 W/(m·K), enhanced by premium PU edge sealing at ≤0.025 W/(m·K), ensures exceptional thermal insulation, maintaining cozy winters and cool summers.

Its porous rock wool structure excels in soundproofing, absorbing noise for serene environments, ideal for hospitals, schools, and studios. Eco-conscious, these panels use recyclable inorganic materials and a sustainable production process, aligning with green building standards. Installation is a breeze, with prefabricated components enabling 600-800 m² daily coverage, slashing construction timelines.

CE certification guarantees top-tier quality, making our 75mm Rock Wool Wall Sandwich Panel the go-to choice for durable, energy-efficient, and safe construction solutions across commercial and residential applications.

3  Production Procedure of Rock Wool Sandwich Wall Panel 

The 75mm Rock Wool Wall Sandwich Panel with CE certification stands out as a top-tier solution, delivering unmatched fire resistance, thermal insulation, and durability. Crafted through an advanced production line, this panel combines cutting-edge technology with high-quality materials to meet diverse building needs.

The process begins with premium stainless steel and color-coated galvanized coils, ensuring a corrosion-resistant and visually appealing surface. These coils are expertly decoiled and coated with a protective layer to maintain integrity. The steel sheets are then corrugated for superior strength, making them perfect for structural applications in industrial, commercial, or residential projects. A preheating stage optimizes bonding, while the rock wool core—made from natural volcanic fibers—delivers exceptional fireproofing, soundproofing, and energy-efficient insulation.

Enhancing durability, a specialized spraying process fortifies the panel’s surface. For projects requiring extra protection, an optional polyurethane side sealing adds airtightness and moisture resistance. The panels are then cured using a double-crawler system, applying consistent heat and pressure for a strong, seamless structure. Precision cutting ensures exact dimensions, followed by careful stacking and automated packaging for safe delivery.

This CE-certified panel excels in performance, offering energy savings through its thermal efficiency and noise reduction for quieter spaces. Ideal for warehouses, offices, or homes, it withstands harsh conditions while maintaining longevity. The production line of the 75mm Rock Wool Wall Sandwich Panel guarantees a reliable, eco-friendly product that meets rigorous European standards, making it a smart choice for modern construction.
