Description
SOPRAFILTRE is a fabric made of a non-woven needle punched polypropylene and polyester fibers.
UNITS PER SKID:
Depends on length and width:
75 m (246.06 ft) 1.75 m (5.74 ft) - 15
150 m (492.13 ft) 3.5 m (11.48 ft) - 1
Material Use:
SOPRAFILTRE is a non-woven, needle-punched polypropylene geotextile fabric designed for use as a filter cloth or separation layer in protected membrane roofing systems. It is primarily used in SOPRANATURE green roofs, roof gardens, and plaza-deck assemblies. Its function is to allow water to pass through while preventing the migration of fine particles, thereby protecting the integrity of the drainage and waterproofing systems beneath.
System Components:
SOPRAFILTRE is typically used in conjunction with other SOPRANATURE system components, including drainage layers, root barriers, waterproofing membranes, and growing media. It acts as a separation and filtration layer within the vegetative roofing system. While it does not require primers or coatings, it is an integral part of the SOPRANATURE assembly and must be installed in coordination with other system layers.
Applications:
SOPRAFILTRE is suitable for use in:
- Green roofs and vegetative roofing systems
- Roof gardens
- Plaza decks
- Protected membrane roof assemblies (PMR)
Application Details:
SOPRAFILTRE is installed by unrolling it loosely over the designated surface. It must be laid with a minimum overlap of 305 mm (12 inches) at both longitudinal and transverse joints to ensure continuous coverage and effective filtration. The material does not require adhesives or mechanical fasteners and is typically held in place by the weight of overlying system components such as drainage boards or growing media.

- Permeability: 1.4 mm/sec (55 mil/sec)
- Filtration Opening Size (FOS): 90–120 microns (3.5–4.7 mil)
Environmental and Installation Considerations:
- SOPRAFILTRE is not affected by UV exposure during short-term installation but should be covered promptly as part of the complete system.
- It is not a liquid-applied product and therefore does not have pot life, curing time, or temperature limitations for application.
- It is a passive component and does not contribute to waterproofing or structural performance but is essential for maintaining system longevity and performance by preventing clogging of drainage layers.
SOPRAFILTRE is a critical component in vegetative and protected roofing systems, ensuring proper filtration and separation to maintain the performance of the overall assembly.
