Application
The root systems of plants on intensive green roofs can damage the building structure. Ad- ditionally, various wind-carried plants may ap- pear on extensive green roofs, including those with aggressive roots or rhizomes, which can threaten traditional waterproofing. Therefore, appropriate root protection must be ensured for every vegetated roof surface.
FLW-400 Specification
Root resistant and vapour control layer made of 0.4 mm thick elastic polyethylene regenerate, root resistance tested according to standard CEN/TS 14416:2014.
