ArmaProtect™ FW2
ArmaProtect™ FW2 is a flexible, fabric-based firestop wrap engineered to restore and maintain the fire-resistance rating of walls and floors at service penetrations. Constructed from a glass filament fabric composite with an internal intumescent insulating layer, it provides high-performance passive fire protection for non-combustible pipes with combustible insulation, composite pipes, conduits, and conduit bundles.
When exposed to extreme heat in a fire event, the intumescent inner coating expands to seal off annular gaps and suppress heat transmission, preventing the migration of flames, smoke, and toxic gases across fire compartments.
Key Features & Benefits
- Improved Reaction to Fire: Achieves a superior Class B-s1, d0 reaction to fire classification (EN 13501-1).
- Ultra-Flexible & Tear-Resistant: The strong glass filament fabric composite easily conforms to large pipe diameters, tight bends, and complex service configurations without cracking or tearing.
- Weathering & UV Resistant: Rated Type X (EOTA TR 024) for durability under conditions exposed to outdoor weathering, frost, and high ambient humidity.
- Wider Coverage Width: Supplied in a 125 mm wide roll format (compared to the 100 mm width of FW1), providing greater contact surface area for larger penetration applications.
- Certified Fire Resistance: Tested and certified up to EI 120 under European Technical Assessments (ETA-21/1026 / EN 1366-3) and FT-Ratings up to 3 hours under UL listings (ANSI/UL 1479 / ASTM E814).
- Safe & Environmentally Friendly: Free from dangerous substances, halogen-free, and safe for indoor environment installation.
