NIDAROOF: Lightweight honeycomb panels for professional blue roof and rainwater management on flat roofs

Nidaroof panels provide a robust, lightweight solution specifically designed for the temporary storage and retention of rainwater on flat roofs, green roofs, roof terraces, and blue roofs. Engineered for professionals in urban areas, these honeycomb-structured panels made of ultra-light polypropylene offer high-performance rainwater management without adding significant weight to the structure. The innovative blue roof approach allows water to be stored temporarily on the rooftop, delaying its release into drainage systems, which aligns with sustainable urban water management objectives.

Key Advantages for Professional Roof Installers

Ultra-Lightweight: Nidaroof panels are made from recyclable polypropylene, providing a lightweight, easy-to-install solution for all types of flat roofs, including blue roofs.

High Compression Strength: With up to 300 kPa compression resistance, Nidaroof panels support structural loads and green roof installations, meeting the durability standards of blue roof projects.

Efficient Water Storage: Nidaroof's 95% void ratio maximizes rainwater storage capacity, effectively turning rooftops into temporary reservoirs that relieve stormwater systems during heavy rains.

Easy Installation: The lightweight honeycomb structure allows for quick, flexible installation, saving time and reducing labor costs.

Blue roof compliance for Sustainable Urban Drainage

Nidaroof complies with local blue roof and rainwater regulations, which are essential for sustainable urban drainage systems (SuDS). Effective water management on flat roofs prevents water stagnation, which can lead to structural degradation, water infiltration, and, in extreme cases, collapse. Nidaroof integrates seamlessly with waterproofing membranes and serves as a temporary drainage layer to prevent excessive load, ensuring professional-grade safety and performance.

Complete professional waterproofing solution

The Nidaroof honeycomb structure, covered with porous geotextile, enables controlled water flow to designated outlets, as required for blue roof systems. Overflow mechanisms provide added security in case of heavy rainfall, ensuring safe water discharge. Professionals should follow the DTU (Unified Technical Document) for compliance with best practices in blue roof installations.
