Applications of the Z110-AI

  • Commercial and institutional green roofs
  • Urban buildings seeking stormwater management solutions
  • Sustainable projects aiming for LEED or equivalent certification
  • Retrofitted rooftops adding vegetative systems

Installation Considerations

Proper placement of the Z110-AI is critical for balanced water retention and drainage. Install at low points within the green roof assembly to ensure even distribution. The perforated screen must remain accessible for inspection and maintenance, ensuring performance over the roof’s lifespan. Integration with other green roof layers—such as soil, root barriers, and vegetation—is key to system success.
