Description
SOPRAFLOW ALU RF aluminum roof drains are designed to collect rainwater on flat roofs during renovation work.
Material Use:
SOPRAFLOW ALU RF is a high-performance aluminum roof drain system designed for the efficient collection and evacuation of rainwater from low-slope roofs, particularly during roof retrofit projects. The system ensures watertight integration with roofing membranes and includes a range of accessories to enhance performance, durability, and ease of maintenance.
System Components:
The SOPRAFLOW ALU RF system is composed of several interrelated components that work together to ensure optimal drainage and waterproofing performance:
- SOPRAFLOW ALU RF Drain: The primary aluminum drain body available in various diameters (2 5/8", 3 5/8", and 5 5/8") and heights (16" and 24").
- SOPRAFLOW SEAL: A watertight EPDM rubber compression joint with heavy-duty nylon flanges and stainless steel screws, essential for connecting the drain to the existing stormwater pipe.
- SOPRAFLOW CLAMPING RING: A powder-coated aluminum ring that mechanically secures the waterproofing membrane around the drain.
- SOPRAFLOW ALU STRAINER: A heavy-duty, oxidation-proof aluminum strainer that prevents debris from entering the drainage system.
- SOPRAFLOW POLE MARKER: A 36" tall fiberglass and nylon marker for easy visual identification of roof drains.
- SOPRAFLOW SEAL SCREWDRIVER: A 24" long tool designed for tightening the compression joint screws in hard-to-reach areas.
- SOPRAFLOW CONTROL and SOPRAOVERFLOW: Optional flow control accessories that regulate rainwater accumulation on the roof.
Applications:
This system is specifically designed for use on low-slope commercial or industrial roofs during retrofit or new construction projects. It is ideal for applications where reliable drainage and integration with waterproofing membranes are critical.
Application Details:
Installation of the SOPRAFLOW ALU RF system involves several key steps:
1. Drain and Seal Installation: The drain plate must be cleaned with a non-greasy solvent, and the top surface primed using a primer compatible with the selected waterproofing membrane (refer to the membrane’s TDS for primer selection). The SOPRAFLOW SEAL is inserted into the drain and tightened to create a secure compression fit. A bead of SOPRAMASTIC or Chem Link M-1 adhesive is applied under the drain plate before securing it to the substrate.
2. Waterproofing Integration: The waterproofing membrane is installed over the drain flange and secured using the SOPRAFLOW CLAMPING RING. Ensure the membrane is fully cured or tempered before clamping.
3. Accessory Installation: The SOPRAFLOW CONTROL and SOPRAOVERFLOW accessories are installed between the membrane and clamping ring if flow regulation is required. The SOPRAFLOW STRAINER is then clamped above the ring, and the POLE MARKER is attached to the strainer for visibility.
Special Notes:
- The SOPRAFLOW ALU RF system must be installed in accordance with SOPREMA’s guidelines and in conjunction with compatible waterproofing membranes.
- The SOPRAFLOW SEAL is a required component for proper installation and watertight performance.
- The system is designed for mechanical fastening and does not rely solely on adhesives.
- The SOPRAFLOW CONTROL and SOPRAOVERFLOW accessories are optional but recommended for roofs requiring controlled drainage.
- The system components are made from corrosion-resistant materials such as aluminum, EPDM, stainless steel, and nylon, ensuring long-term durability.
- No specific environmental limitations (e.g., temperature or humidity) are provided in the TDS for installation, but standard roofing practices should be followed.
- This system does not include liquid-applied materials, so there are no pot life, curing time, or wet mil thickness specifications.
This system is a robust and modular solution for roof drainage, offering flexibility and compatibility with a wide range of SOPREMA waterproofing systems.
