One reason we stopped using ACP on mid-rise facades. Aluminum Composite Panels look great. They're lightweight. They're affordable. They come in any color. They seemed perfect for this mid-rise residential project. Then we started seeing issues. The panels were denting during transport. The joints were showing gaps after a year. The color was fading unevenly. The maintenance team was complaining about cleaning difficulty. But the real problem wasn't the material. It was the application. ACP works great for low-rise buildings. For signage. For interiors. But for mid-rise facades exposed to monsoon weather? Not so much. We switched to a different system. More expensive upfront, but cheaper long-term. Better performance. Less maintenance. Happier clients. The lesson: Just because a material works in one context doesn't mean it works in every context. Context matters more than material.
