When sourcing design facades, material selection directly impacts durability, aesthetics, and maintenance. Common materials include Aluminum Composite Panels (ACP) for lightweight versatility, Fiber Cement for fire resistance, and Perforated Metal for modern ventilation. Ensure the material has a PVDF coating (Polyvinylidene Fluoride) if used outdoors, as this provides superior UV resistance and color retention for over 15-20 years. For glass facades, prioritize Double Glazing (IGU) with Low-E coating to optimize thermal insulation.
