Platon for Green Roofs: Extensive green roof: Platon DE25

Extensive green roof: Platon DE25

Premium water storage and drainage board

Platon DE25 is a perforated studded sheet designed to store and drain water on extensive green roofs. Over 2 million square meters of this product have met the harsh demands of architects, contractors and customers globally over the past 25 years.

Platon DE25 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.
