Retrofitting FZ400 Movement Joint Filler | Fire Stopping Solution
Retrofitting FZ400 Movement Joint Filler for Fire Stopping in Building Movement
In today’s construction landscape, balancing fire safety with structural flexibility is essential. Buildings naturally shift due to thermal expansion, seismic activity, and settling making expansion joints a necessary but vulnerable feature. These joints can compromise fire compartmentation if not properly sealed. That’s where the FZ400 Movement Joint Filler excels: a retrofit-friendly, high-performance solution that combines fire resistance with movement accommodation.
✅ Why Movement Joints Need Fire Protection
Movement joints traverse walls, floors, and ceilings breaching fire-rated assemblies. Without proper sealing, they allow flames, smoke, and gases to spread during a fire. Traditional joint fillers often lack fire resistance, while firestop products may not flex with building movement. The FZ400 solves both problems, making it ideal for retrofitting older buildings or upgrading passive fire protection systems.
✅ FZ400 Key Benefits
- High movement capability: Adapts to wide joint widths and cycles without losing integrity.
- Certified fire resistance: Tested for up to 4 hours of protection depending on installation.
- Easy retrofit installation: pre-compressed, lightweight, and tool-free application
- Durable performance: Resists aging, moisture, and environmental wear over time
✅ Retrofit Made Simple
Unlike invasive firestop systems, FZ400 installs cleanly into existing joints. Contractors can cut it to size and press it into place manually no adhesives or special tools required. It conforms to irregular or shifted joints, making it perfect for heritage buildings or seismic zones.
✅ Long-Term Compliance & Safety
As global fire codes evolve, facilities must reassess their passive fire protection. FZ400 helps meet these standards without costly reconstruction. Its long-term durability ensures continued fire integrity, even after repeated movement cycles.
✅ Applications
- Horizontal and vertical movement joints
- Seismic joints in hospitals, airports, and commercial buildings
- Fire compartment separations in retrofit and heritage projects
FZ400 Movement Joint Filler is the smart choice for building owners, fire safety professionals, and contractors seeking a cost-effective, compliant, and flexible fire stopping solution. Retrofit with confidence protect with precision.
