How does ACP cladding handle seismic movements versus traditional masonry walls?

Aluminum composite panel (ACP) cladding exhibits excellent seismic performance compared to rigid masonry walls. ACP systems are mounted on lightweight sub-frames with sliding clips and elongated fastener holes that allow controlled panel movement during seismic events. The system accommodates building drift and thermal expansion without cracking or detaching. The joints between panels, sealed with flexible gaskets and sealants, maintain watertightness even under dynamic loads. Conversely, traditional masonry walls—brick or concrete block—are inherently rigid and transfer seismic forces into the structure, risking mortar joint failure, spalling, and collapse. Masonry retrofits require expensive reinforcement or base isolation to improve performance. ACP’s low mass reduces inertia forces, mitigating horizontal acceleration effects on the building envelope. In high-risk zones, fire-rated ACP panels with mineral cores maintain fire safety and structural integrity post-quake, whereas damaged masonry may compromise safety. For suspended aluminum ceilings, ACP modules on seismic-rated hangers prevent panel disengagement. Overall, ACP cladding provides a flexible, lightweight facade solution that enhances seismic resilience compared to traditional masonry walls.
