Fleeces   Catalog   Quality Guarantee APP supplies various non-woven fleeces, appropriate for a range of applications, such as rooftop gardens, garden projects and road building. The production of APP non-woven fleeces is tested according to the strict ISO 9001 quality certificate. In addition, regular checks by independent testing laboratories such as the TBU Germany confirm consistent fleece quality. The products are made from polypropylene fibres, which are bitumen resistant, and are biologically and chemically neutral, and fulfil the demands of the Guidelines for the Planning, Execution and Upkeep of Green Roof Sites (FLL).   APP separation fleece VLT-130 The VLT-130 PP non-woven fleece separates the chemically incompatible layer on the roof and prevents sweating of the PVC softening agent. On one side, it is thermally hardened, rot-proof, and chemically and biologically neutral.   VLF-150 and VLF-200 Filter Fleeces These polypropylene filter fleeces inhibit the leeching of fine particles from the substrata into the drainage layer. Low weight by unit area combined with high permeability permit a high rate of abstraction. Their hydraulic properties are improved by thermal hardening on one side. A variety of fleece weights may be used, dependent upon the maximum load required. The filter layers may also be used on inverted roofs. Guidlines for Roof Gardens "Sheets of non-woven fabrics laid as a filter course must overlap by a minimum of 10cm, and they must be brought up at the edge to beneath the surface of the vegetation support course" (FLL).           Separator Filter Dim VLT-130 VLF-150 VLF-200 Application     Filter layer for extensive roof garden projects Filter layer for intensive roof garden projects Weight by unit area [g/m2] 130 150 200 Thickness [mm] 1,7 1,9 2,1 Tensile strenght weft [kN/m] 7 8 11 Tensile strenght warp [kN/m] 9 12 14 Elasticity [%] 60/80 60/70 70/60 CBR X 1550 1850 2300 CBR x-s 1400 1700 200 Robustness class GRK 2 3 3 Effective opening with [mm] 0,14 0,13 0,09 Water permeability (2 kpa m/s) Water retention capacity   [m/h]/ [l/m2] 5,3*10-3 5,3*10-3 3,1*10-3 Material   Polypropylene Density [g/cm3] 0,9 0,9 0,9 Melting point [°C] ±165 ±165 ±165 Manufacturing process   Mechanically hardened, thermally treated Roll width [m] 2,5 2,5 2,5 Roll lenght [m] 150 100 100 Roll area [m2] 375 250 250 Roll weight [kg] 49 40 50 Roll diameter ca. 50 45 45 Colour   White White White   Catalog
