Fire, Smoke, and Condensation Protection

“Navycross” Sealing System – A0-A60 Class

The Navycross system is a fire-rated sealing solution for A0 to A60 class partitions, designed to ensure effective compartmentalization in accordance with marine safety standards. It provides high-performance fire resistance for cable, pipe, and duct penetrations, maintaining the structural integrity and safety of ship partitions.

For electric cable penetrations, pipe bundles, and single pipe transits:

  • Class A-60 divisions
  • Class A-0 divisions
  • Watertight divisions

The patented FIRESHIELD system offers a simple, practical, functional, versatile, compact, and cost-effective solution for sealing cable and pipe penetrations. It effectively prevents the spread of fire through openings in bulkheads and decks.

Additionally, the system allows for quick and easy modifications to penetration points—such as expansions, reductions, or design changes—without any risk of damaging cables, even those already installed.

Application Notes

  • Manually press the special containment modules (made of metal clips) into place around the edges of the penetration opening.
    • Maximum preset dimensions: 500×250 mm
    • No minimum dimension restrictions
  • Seal the transit area, where needed, using special filler modules made of flame-retardant polyurethane strips, wrapping them around the cables or pipes.
    • When installing the system, cable surfaces may be in direct contact (cable-to-cable distance: 0 mm).
  • Apply Navycross® sealant, ready to use, to both sides of the sealed opening, ensuring a minimum thickness of 10 mm.
    • After application, do not move the plugging for at least 24 hours to allow proper surface curing.
    • One-sided sealing is also possible, if necessary.
