Overview
The ArchiGreen® SL separation sheets: SL 100 and SL-I 125; and FL filter sheets FL 150 and FL 200 are needle punched non-woven geotextiles made of the finest virgin polypropylene fibres. They are all black in colour. Being virgin polypropylene the fibres used, demonstrate extreme durability in maintaing their porous structure. This is paramount to ensure that these engineered fibres are capable of conducting their filtration duties over decades to come in a green roof build-up. Other features related to their polypropylene nature are also vital; including their rot-proof attribute and their excellent resistance to microorganisms. Backed by EN12225, a method for determining the microbiological resistance by a soil burial test, all of the non-wovens described above are supplied with a
25-year functionality guarantee as per conditions set in the standard EN 12225:2000. Furthermore, all of these non-woven geotextiles are CE-marked.
