UL 2079 Tested Seismic Fire Barrier Systems: styleJOINT I-FIRE®
Looking ahead to our 25th anniversary: International leaders in certified expansion joint fire containment systems. UL 2079 testing compliance and a 5-year warranty.
styleJOINT I-FIRE® provides certified 2-hour to 4-hour fire barrier blanket systems engineered to seal expansion joint openings in floors, walls, and ceilings against heat, toxic gases, and flames.
Tested under UL 2079 and ASTM E1966 with pre-burn cyclic seismic movement verification, I-FIRE guarantees life-safety integrity across major hospitals, data centers, airports, and commercial high-rises.
Engineering Considerations When Specifying Fire Barriers
1. Movement Criteria: It is critical to quantify dynamic joint displacement under thermal cycling and multi-directional seismic drift to ensure the specified assembly withstands shear without tearing.
2. Rating Requirements: Expansion assemblies must meet the specific hourly fire endurance ratings (2 to 4 hours) mandated by local building codes and life-safety plans.
3. Code Compliance: Verify that fire barrier blankets carry certified testing under UL 2079, ASTM E119, ASTM E1966, and IBC 2024.
4. Life-Safety & Liability Mitigation: Specifying third-party certified fire barriers (UL/Intertek) guarantees that toxic gases and extreme heat will not migrate across compartment zones during a structural fire event.
Fire Barrier Joint Systems Portfolio
Explore our specialized fire-resistive assemblies for floors, walls, and structural slabs. Engineered with high-purity ceramic fiber matrices, stainless steel encapsulation, and elastomeric seals.
Floor Fire Barrier Blanket Systems (PF)
The Pyro-Flex Floor Fire Barrier System (PF) is a high-performance fire-resistive assembly engineered to seal horizontal expansion joint openings. Constructed from high-purity flexible ceramic fiber blankets, stainless steel foil, and a fire-resistant textile matrix. Secured directly into the joint gap from the top down. Extensively specified in commercial towers, stadiums, and parking decks.
Special Features: Fully compatible with elastomeric waterproof expansion joints without secondary under-slab pans. Eliminates wet fire caulk sealants. Accommodates dynamic lateral seismic shear.
