Facades employ multiple layers for various functions: exterior cladding for aesthetics, an air gap for ventilation, a rain screen for water management, thermal insulation for energy efficiency, a vapor barrier to prevent moisture, structural sheathing for support, an air barrier to reduce leaks, and an interior finish for appearance. The facade is secured with an attachment system and sealed with sealants or gaskets for weather-tightness. Layer composition adapts to design, مناخ, and performance needs, adhering to building standards for safety and efficiency.
