FLW-1000
Root resistant membrane made from PVC, which is placed at the lowest level of the typical layer build-up of the DIADEM system, to prevent the root systems from penetrating through and protecting the pre-existing insulation. If sheets are joined they provide additional roof insulation. Suitable for semi-intensive and intensive green roof types and for roofs that require additional roof insulation.
