Root-resistant filter fabric serves to prevent root penetration into the underlying roofing, if it is not root proof. The function of the existing roofing is completely preserved. This also determines the lifespan of the green roof. The green roof does make sure that the durability of the roofing is extended.
That means that root-resistant filter fabric does not replace the function of the underlying roofing. For this, a prefabricated EPDM membrane is suitable.
We offer three-layer LDPE root-resistant filter fabric, which can be laid down loosely, with an overlap of at least 40 cm. The thickness varies from 0.2 mm to 0.5 mm and we deliver in widths of up to 500 cm. Root-resistant filter fabric is delivered on a roll of up to 500 m2.
