In the realm of curtain wall facades, the role of cavity barriers is paramount to the integrity and safety of a building's structure. The understanding that these walls indeed experience movement has become a recognized fact within the industry. From wind loads to the potential for seismic events, these dynamic stresses continuously impact the function and reliability of the cavity barriers. While curtain wall facades exhibit resilience, the vital consideration is their behavior under extreme conditions such as fire, where the stability of materials like extruded aluminum is tested. The dialogue surrounding the design of these barriers involves not just accommodating movement but also adhering to strict building regulations and compliance measures. A robust specification
