This document provides an overview of aluminium composite panels (ACP). It discusses that ACP is made up of two aluminium sheets bonded to a low-density core. This creates a lightweight yet rigid sandwich structure. The core takes shear loads while the skins take tension and compression loads. ACP offers advantages like aesthetics, insulation, light weight, durability, and low maintenance. It can be installed using rivets or screws and cut using saws. ACP has properties such as heat and weather resistance, sound dampening, and comes in various colors and sizes for façade cladding and signage. Examples of its use include spaceship earth and buildings at Amity University.
