The use of aluminium composite panels can be traced back decades. However, a tragic incident in 2017 - the Grenfell Tower fire in London — drew worldwide attention to this product. The old-style aluminium composite material used on the building's front was largely responsible for the fire's rapid spread. This incident not only made the ACP sheet popular but also raised questions about its usability and safety. Aluminium composite panel, often known as ACP sheet, is a sandwich panel made up of three layers: aluminium sheet, FR Core, and aluminium sheet. In addition to these three primary layers, there are multiple more films and layers, such as protective film, paint coating, and adhesive layers, to name a few. All of these substances work together to make ACP an ideal robust building material that gives incredible strength to the structure.
