Fireproof foam sealing for cable trays

Fireproof foam and intumescent materials can effectively seal cable tray penetrations, maintaining fire resistance up to EI 240 when installed according to manufacturer guidelines and fire-rated standards.Overview of Fireproof Sealing Materials

Intumescent foam and pillows are commonly used to seal cable tray penetrations. Products like FYLLOFOAM and AF BAGS are designed to expand or insulate under heat, preventing fire and smoke from spreading through openings in walls or floors . These materials are tested to comply with EN 1366-3 and other international fire standards, providing ratings such as EI 120, EI 180, or E240 depending on the product and installation. Key materials include:

  • FYLLOFOAM: Foam rubber sheets based on NOFIRNO rubber, cut to match conduit thickness, combined with HR conduit sleeves for B-class penetrations, tested for up to 4 hours fire resistance .
  • AF BAGS: Intumescent pillows in a non-combustible fiberglass casing, suitable for cables up to 21 mm diameter, with a sealing depth of 120 mm, certified for EI 120–240 .
  • Moldable putty and caulks: Products like 3M Fire Barrier Moldable Putty+ or IC 15WB Caulk can seal gaps around cables and trays, providing smoke and fire containment .
Installation Method
  1. Measure the Cable Tray Opening: Determine the width and height of the tray and the penetration opening. Add clearance as recommended by the manufacturer (e.g., 1.5” larger than the tray for pillow installation), .
  2. Select Appropriate Fireproof Material: Choose foam sheets, intumescent pillows, or putty based on the fire rating required and the type of wall or floor construction.
  3. Prepare the Penetration: Ensure the opening is clean, dry, and free of debris. For retrofits, remove any old sealant or insulation.
  4. Insert Fireproof Material:
    • Foam sheets: Cut to size and insert into the opening, filling gaps around cables. Use kneadable rubber (e.g., FIRAQUA) for small voids .
    • Intumescent pillows: Place pillows inside the opening, ensuring full coverage. Pillows can be repositioned for maintenance or cable modifications .
    • Moldable putty/caulk: Apply around the edges of the tray or between pillows to ensure a continuous seal .
  5. Secure and Support: Use conduit sleeves, mounting brackets, or splice plates as needed to hold the foam or pillows in place, especially for vertical or overhead installations .
  6. Label and Inspect: Mark the firestop location and verify installation depth, coverage, and compliance with UL/EN listings. Conduct QA/QC inspections according to method statements .
Maintenance and Compliance
  • Fireproof foam and pillows should be inspected periodically to ensure they remain intact and have not shifted due to vibration or cable changes.
  • Any modifications to the cable tray or penetration require reinstallation or adjustment of the fireproof material.
  • Always follow manufacturer instructions and local fire safety codes to maintain the certified fire rating. By following these steps and using certified materials, cable tray penetrations can be effectively sealed to prevent fire and smoke propagation while allowing for maintenance and future cable additions.
