Platon DE20Water storage and drainage board for extensive green roofs

Product description

Platon DE20 Green Roof Tray is a studdedsheet with formed cavities and channels. Whenapplied to a green roof construction, above aroot protecting layer and below a filter fabric,the cavities are able to store water, whichpercolates through the soil from the surfacevegetation. Water rising above the level of theinterconnecting channels is distributed betweencavities. Drainage slits through the channelsallow excess water to drain through to the gapbelow (created by the studs), so that drainagetakes place above the root protecting layer acrossthe flat roof.The product thereby creates both adrainage layer and a water storage layer in theconstruction.
