Platon for Green Roofs: Intensive green roof: Platon DE40

Intensive green roof: Platon DE40

Premium water storage and drainage board

Platon DE40 is a thick, highly durable water storage and drainage board designed to meet harsh demands on intensive green roofs. With 10 l/sqm water storage and 40 mm studs height Platon DE40 is the storage giant among drainage elements for green roofs.

Platon DE40 is a studded sheet with formed cavities and channels. When applied to green roof construction, above a root protecting layer and below a filter fabric, the cavities are able to store water, which percolates through the soil from the surface vegetation. Water, rising above the level of the interconnecting channels, is distributed between cavities. Drainage slits through the channels allow excess water to drain through to the gap below (created by the studs), so that drainage takes place above the root protecting layer across the flat roof. The product thereby creates both a drainage layer and water storage layer in the construction and secures appropriate aeration for plants‘ roots as well.
