At 100kg/m³, this product represents the lightweight end of the rock wool spectrum, effectively reducing facade system weight and minimizing structural load—ideal for weight-sensitive high-rise buildings and renovation projects.
Optimized production processes achieve maximum cost control while maintaining Class A fire resistance and thermal performance, offering the best value-for-money insulation solution for construction projects.
Meets Class A non-combustible material standard: does not burn, emit toxic fumes, or produce molten droplets. As the primary insulation layer, it provides reliable everyday fire safety for buildings.
Stable fiber structure ensures low thermal conductivity and lasting insulation, supporting green building certifications.
Lightweight property makes on-site handling, cutting, and installation more efficient and labor-saving, with good compatibility with various substrates and organic insulation materials for flexible application.
High acidity coefficient ensures resistance to corrosion and aging—no powdering, no shrinkage, no collapse over time, ensuring insulation system lifespan matches the building itself.
