Fireblocking fundamentals for exterior cladding systems
Cavity fireblocks are a critical yet often overlooked component of ventilated rainscreen façade systems in North America. While building codes establish basic requirements, long-term façade safety depends on understanding how different types of fireblocks perform in real-world conditions.
This webinar explores the essential role fireblocks play in limiting concealed fire spread within exterior wall assemblies, examines key code requirements, and highlights the factors designers, specifiers, contractors, and building owners should seriously consider when evaluating fireblock performance. Attendees will also learn how testing, third-party certification, installation quality, and inspection documentation contribute to safer, more resilient building envelopes.
Attendees / delegates will learn:
- How rainscreen façade systems function and why cavity fire barriers are essential to their long-term fire performance.
- How to balance moisture management and fire compartmentation without compromising façade performance.
- What current code requirements demand and the additional performance considerations that may sit beyond basic compliance.
- How to evaluate fireblocking solutions using fire testing, third-party certification, durability, and compatibility with façade interfaces and penetrations.
- Why inspection, documentation, and traceability matter, helping create a verifiable record of installation quality and ongoing building safety.
