Description
SOPRADRAIN ECO-VENT is a drainage panel composed of a post-industrial recycled polypropylene drainage core of fused, entangled filaments onto which a fabric made of a non-woven needle-punched polypropylene fibers is factory-laminated.
UNITS PER SKID: 8
Material Use:
SOPRADRAIN ECO-VENT is a high-performance drainage panel designed for use in green roofing systems, roof gardens, plaza decks, and other vegetative or landscaped waterproofing assemblies. It serves as a drainage and ventilation layer, facilitating water flow and vapor diffusion while protecting the underlying waterproofing and insulation layers.
System Components:
SOPRADRAIN ECO-VENT is typically used as part of the SOPRANATURE vegetative roofing system. It is installed over SOPRA-XPS insulation boards, which are placed on top of a protected waterproofing membrane. The system may also include other SOPRANATURE components such as filter fabrics, growing media, and vegetation layers. The drainage panel itself consists of a polypropylene drainage core with a factory-laminated non-woven, needle-punched polypropylene fabric.
Applications:
This material is suitable for use in:
- Green roofs and roof gardens
- Plaza decks
- Retaining walls
- Underground parking structures
- Exterior planters
Application Details:
SOPRADRAIN ECO-VENT is supplied in rolls and is unrolled directly over the insulation layer (typically SOPRA-XPS) on protected membrane roofs. Care must be taken to ensure proper overlap of the fabric between adjacent panels to maintain continuous drainage and filtration. The product is flexible and conforms to surface contours, making it easy to install on various substrates.
Special Notes:
- Material Composition: The drainage core is made of azure blue polypropylene with a square waffle pattern for flexibility and vapor diffusion. The laminated fabric is black, non-woven, and needle-punched polypropylene.
- Dimensions: Each roll is 10 mm (0.4 in) thick, 30.5 m (100 ft) long, and 1220 mm (48 in) wide, with a 76 mm (3 in) fabric overlap. Gross coverage per roll is approximately 37.2 m² (400 ft²).
- Weight: Each roll weighs approximately 25.2 kg (55.6 lb).
- Performance Characteristics:
- Compressive Strength: >1436 kPa (>30,000 psf) per ASTM D1621 Modified
- Flow Rate: 5500 l/min/m² (135 gal/min/ft²) per ASTM D4716
- Puncture Strength: 1380 N (310 lbf) per ASTM D4833
- Permittivity: 1.7 sec⁻¹ per ASTM D4491
- Apparent Opening Size: 0.212 mm (70 US Sieve) per ASTM D4751
Environmental and Installation Considerations:
- SOPRADRAIN ECO-VENT is not a liquid-applied product and therefore does not have pot life, curing time, or temperature/humidity limitations typical of coatings or adhesives.
- It is UV-resistant to a degree but is typically installed beneath other system components (e.g., soil, pavers, or vegetation) and not exposed to direct sunlight for extended periods.
- The product is designed for use in protected membrane assemblies and should not be used as a standalone waterproofing or exposed drainage solution.
System Integration:
SOPRADRAIN ECO-VENT is an integral part of the SOPRANATURE green roof system and must be used in conjunction with compatible SOPREMA products such as SOPRA-XPS insulation and appropriate waterproofing membranes. It does not require primers or coatings and functions as a passive drainage and ventilation layer within the system.
This material is ideal for sustainable construction projects seeking to incorporate green infrastructure, manage stormwater, and enhance building envelope performance through vegetative roofing systems.
