Rock wool Sandwich Roof Panel

1 Product Parameters

2 Product Features

With a Class A non-combustible rock wool core, sourced from natural volcanic rock, this panel delivers over 2 hours of fire resistance, offering unmatched protection for buildings like warehouses, schools, or offices. It’s a top pick for those prioritizing fire-resistant roofing.

Designed for durability, its density spans 80kg/m³ to 150kg/m³—typically 120kg/m³—with a compressive strength of ≥150KPa. Sandwiched between two robust steel layers, it stands firm against storms, winds, and wear, ensuring lasting performance in any climate.

For thermal insulation, the panel shines. Its fine rock wool fibers achieve a thermal conductivity of ≤0.043W/(m·K), while optional PU edges drop to ≤0.025W/(m·K). This creates a cozy indoor environment—warm in winter, cool in summer—cutting energy bills and boosting comfort. It’s a standout among thermal insulation panels.

Sustainability sets it apart. Made from recyclable, inorganic materials via an eco-friendly process, it reduces your carbon footprint. Plus, its prefabricated structure speeds up installation, covering 600㎡ to 800㎡ daily, saving time and labor costs.

Whether you’re an architect, contractor, or property owner seeking eco-friendly building materials, the Rock Wool Sandwich Roof Panel offers reliability and innovation. Optimize your project with a roofing system that excels in safety, insulation, and green design—perfect for modern, responsible construction.

3  Production Procedure of Rock wool Sandwich Roof Panel

The process begins with automated decoiling, followed by optional film application for enhanced protection. Steel sheets can be profiled into corrugated forms to increase strength and rigidity. Preheating ensures optimal adhesion with the core material. We meticulously process and cross-butt strips of high-density rock wool, creating a seamless and highly effective insulation layer. A specialized spraying section applies high-performance adhesives, bonding the layers together before entering the double-crawler curing oven. This critical stage guarantees uniform pressure and perfect lamination. Depending on project specifications, panels can be produced with or without polyurethane side sealing for improved weather resistance and edge protection. The continuous production line culminates in precise cutting to specified lengths, automated stacking for efficient handling, and secure packaging for safe transportation. 

Our Rock Wool Sandwich Roof Panels are the ideal choice for industrial, commercial, and residential buildings demanding exceptional insulation, fire safety, and longevity.
