VLU-300, VLU-500 and VLU-800 Protector Fleeces

APP Protector Fleeces guard the surface of the roof from damage. The greater the stress to which the installation is subjected, the stronger the protection fleece will need to be. The protection layer is laid over a root-resistant seal or root barrier. The fleeces inhibit root growth after installation. The technical data of the APP Protective fleeces comply with the requirements of DIN 18195.

 

VLS-500/800 Water-Retentive Fleece

The VLS Water-retentive fleece, which is made from very thin fibres, protects the roof Fleece and retains water and nutrients for the plants. It is installed above the root-proof barrier. The fleece can absorb seven times its own weight of water. A certificate for this performance is available.

Different weights per unit area and roll dimensions may be produced to the customer's requirements. The products should not be exposed to direct sunlight for longer than four weeks, as they are not UV-stabilised. All the values presented in this table are averages from standard tests. In practice, slight fluctuations occur in actual production. Consistency in production according to DIN ISO 9001 is assured. We reserve the right to change amend specifications.
