ISO-DRAIN nature 40 P 2.0 – the new generation for high-performance green roofing

The requirements relating to modern green roofing and effective water management are growing all the time. Frequent heavy rainfall events are putting pressure on sewer systems, while long dry spells are placing huge strain on vegetation – especially on roofs. Green roofs can help keep urban areas cool during summer heatwaves.

ISO-DRAIN nature 40 P 2.0 is a solution that combines the tried-and-tested features of ISO-DRAIN nature 40 P with an optimised water storage capacity of approximately 23 l/m² – all with a consistent installation height of just 40 mm.

Advantages of ISO-DRAIN nature 40 P 2.0

  • Efficient supply of water
    The water storage capacity helps ensure the supply of water for green roofs.
  • Use of rainwater
    Stored rainwater is available for the vegetation and can reduce water losses.
  • Support for the greening system
    The combination of water absorption, drainage and aeration helps the green roofing structure function effectively.
  • Prevention of waterlogging
    The drainage function helps excess water drain away.
  • Promotion of root aeration
    The design improves aeration and diffusion in the root area.
