A curtain wall is a non-load-bearing exterior cladding system, typically composed of aluminum profiles and glass assembled into architectural panels, designed to enclose a building without transferring significant gravity loads to the primary structure. Its primary function is to protect the interior from environmental conditions, regulate natural light entry, and provide a contemporary architectural aesthetic.

This system is anchored to the main structure through a secondary framing system that supports the panels. It is engineered to withstand wind and seismic loads while accommodating movement without compromising performance. Curtain walls provide high thermal and acoustic performance, energy efficiency, and design versatility, making them widely used in corporate, commercial, institutional, and high-rise buildings.
