What are the common challenges in installing aluminum ACP panels on facades?

Efficient and precise installation of aluminum composite panels (ACP) is critical to achieving the envisioned façade aesthetic and performance. One primary challenge is ensuring the support subframe is perfectly level and plumb; any deviation can lead to uneven reveal widths, panel distortion, or misalignment at corners. Accurate panel layout planning—based on detailed shop drawings—mitigates the risk of last-minute adjustments that disrupt project schedules. Properly accounting for thermal expansion and contraction is essential; inadequate gap spacing can cause buckling or warping under temperature fluctuations, while excessive clearance undermines wind load resistance. Selecting and installing correct fasteners, clips, and anchors according to manufacturer guidelines prevents over-tightening, which can dent the aluminum skin or damage coatings. Another common hurdle is achieving consistent sealant application; using the right sealant type, tooling method, and joint backing rod ensures watertightness and resilience against UV degradation. Finally, coordinating installation sequencing with other trades—such as glazing, insulation, and waterproofing—requires clear communication to avoid damaging ACP panels before final fastening. Addressing these challenges through rigorous quality control, skilled installers, and adherence to best practices results in flawless, durable façades and ceilings.
