Aluminum is widely used in exterior walls mainly due to its high strength-to-weight ratio, excellent corrosion and weather resistance, and ideal durability. Coupled with its other properties such as easy installation, fire resistance, and design flexibility, aluminum has become a cost-effective and efficient choice for modern construction. While the initial cost of aluminum may be higher than some other materials, its long-term benefits in terms of maintenance, durability, and energy savings can make it a cost-effective choice.
