Green Roof Lightweight Hydrophilic Rock Wool Water Retention Layer

This product is engineered for structural load capacity and water retention design, solving the dual constraints of load limits and water demand on green roofs. The lightweight hydrophilic rock wool element provides ample water storage for plants while ensuring structural safety, making rooftop greening not just possible but reliable.

Extensive green roofs, rooftop gardens, garage roof greening of new built or retrofit buildings

• Ultra-lightweight Density only 60kg/m³, with saturated weight below traditional substrates. Can be used for retrofit existing buildings without structural reinforcement, significantly lowering project thresholds and renovation costs.
• High water retention Effective void rate ≥ 90%, capable of storing several times its own weight in water, reducing irrigation and maintenance frequency.
• Breathable and insulating Porous structure provides thermal insulation, reducing roof surface temperature by 10-15°C in summer and lowering building cooling energy consumption, gaining both landscaping and energy-saving benefits.
• Withstands extreme temperature variations Inorganic material with stable thermal properties, performing reliably from -20°C to 80°C. Whether in severe cold or extreme heat, the product maintains performance.
