ISO-DRAIN nature 40 P 2.0
The new generation for high-performance green roofing – ISO-DRAIN nature 40 P 2.0 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.
When having to contend with both heavy rainfall and dry spells, getting water management right is vital.
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.
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.
Wide-ranging applications
ISO-DRAIN nature 40 P 2.0 is suitable for a variety of green roofing systems. It can be used on cold, warm, inverted and retention roofs (blue roofs).
Suitable for:
- Cold, warm and inverted roofs
- Retention roofs / blue roofs
- Extensive greening with a raised layer structure
- Simple intensive greening with a lower layer structure
System benefits:
- Contribution to the supply of water for the vegetation
- Drainage and water storage functions
- Improvement of aeration and diffusion
- The retention volume can have a positive impact on the green roof’s discharge performance
