Roof drain green roof.

It forms an extremely stable and pressure resistant sub base and sometimes serves as an additional thermal air layer. The drainage layer is applied over the entire roof area. Our flexible adaptable components can be configured to meet even the most challenging custom green roof specifications. A function of the drain layer is the application of a root resistant filter fabric.

During a dry period the water stored can be reabsorbed by the vegetation layer above. The drainage also contributes to good aeration of the plant roots. Enclosing a drain in perforated stainless steel will prevent the drain from operating properly and very quickly due to the s s plugging with green roof debris. The green roof solutions drainage conduit is a stainless steel channel for use with the aggredrain system.

Green roofs comprise a multi layered system that covers the roof of a building or podium structure with vegetation cover landscaping.

The 6 slotted triangle shape is used beneath the aggredrain layer and allows for water to flow freely. The drainage layer has an important role to play in the total system structure of a green roof.

The roof is likely to consist of an impermeable layer a susbstrate or growing medium and a drainage layer although not all green roofs require a drainage layer. It buffers water and allows excess water to drain away.
