Key Features
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.
