Aluminium cladding is sustainable due to its recyclability, durability, and energy efficiency. When sourced responsibly, manufactured using eco-friendly processes, and properly maintained, it can significantly reduce resource consumption and minimize waste. However, attention must be paid to the environmental impacts associated with its production and disposal. Overall, aluminium cladding can be a sustainable choice for building exteriors, but careful consideration of its lifecycle and environmental implications is crucial to maximizing its sustainability benefits.
