High Compression Strength Fireproof Rock Wool For Roofing System

Our high compressive strength roof fireproof rock wool is engineered for airport terminals, convention centers, and large transportation hubs with large-scale roofing systems. Featuring high-density rock wool formed through 3D pleating technology with excellent compressive strength, ensuring long-term stability under combined equipment loads, maintenance loads, and wind loads.

• Steel structure roof insulation for airport terminals, railway stations
• Large-scale roof systems for convention centers, stadiums
• Industrial plants, logistics centers
• Metal roofs requiring installation of HVAC units, PV systems, and maintenance walkways

• High Compressive Strength - Reliable Load-Bearing: Compressive strength ≥80kPa (depending on density), capable of supporting concentrated loads from equipment installation and maintenance access—no deformation, no settling over time.
• Class A1 Non-Combustible - Roof Fire Barrier: Meets the highest Class A1 non-combustible standard: no burning, no molten droplets, no toxic fumes, effectively preventing fire spread across the roof.
• Dimensional Stability - Long-lasting Performance: High acidity coefficient ensures weather resistance—no powdering, no shrinkage under temperature fluctuations and UV exposure, ensuring long-lasting performance.
• Thermal Efficiency - Green Building Compliance: Low thermal conductivity meets building energy efficiency standards, supporting green certifications for airport and convention projects.
• Easy Installation - Metal Roof Compatible: Uniform product dimensions allow direct installation over profiled steel sheets or concrete substrates, perfectly integrating with roofing systems.
