Advantages • Bitumen-proof, oil-proof and polystyrene-proof • May be installed as vapour control layer and skid membrane as well DIADEM® build-up • extensive vegetation • extensive substrate (SEM) • VLF-150 filter fleece • DD-25H drainage layer • VLF-110 • FLW-400 root protection layer • VLU-300 technical protection fleece • not root-resistant water proofing • additional layers Application The vegetation of extensive green roofs usually doesn‘t pose a danger to the building structure, but carried by the wind, various plants can appear on the roof, that have aggressive roots and even ones with rhizomes, that are able to damage traditional water proofing, therefore the root-protection of every roof with vegetation has to be ensured.
