Z110 green roof drain shown with 18 height for intensive green roofing applications.
Green roof roof drains.
Zurn manufactures a line of green roof drains featuring customizable enclosures to align with the green roof surface.
The design of the different drainage layers allows for a portion of the stormwater to be retained above where the water is allowed to flow freely off of the roof.
Our flexible adaptable components can be configured to meet even the most challenging custom green roof specifications.
The drainage off a green roof surface is a particularly important component to maintain optimum growing conditions in the growth medium to managing heavy rainfall without sustaining damage to growth media due to erosion or ponding of water and to ensure the sound engineering and structural integrity of the roof.
The most critical role of the drainage layer is to provide an adequate flow of water off the roof during and after rainfall.
The drainage layer has an important role to play in the total system structure of a green roof.
The drainage also contributes to good aeration of the plant roots.
It buffers water and allows excess water to drain away.
Z110 green roof drains are available with enclosure heights ranging from 5 to 18 or as specified.
