Yes, aluminum sheets can be used for exterior cladding. They are known for their durability, resistance to corrosion, and low maintenance requirements. Aluminum is lightweight, which makes it easier to install compared to heavier materials. It also has good thermal properties, helping to insulate buildings. Additionally, aluminum can be coated with various finishes, allowing for a wide range of aesthetic options. However, it's important to ensure proper installation and sealing to prevent water infiltration and to maintain the cladding's performance over time.
