At its core, a photovoltaic curtain wall consists of several hardware and software components working in tandem. These innovative systems combine aesthetics with functionality, allowing buildings to generate power while maintaining visual appeal. Learn how these solar-integrated building solutions enhance energy efficiency, provide fire safety, and improve architectural. . Curtain walling refers to a non-structural cladding system made from fabricated aluminum, commonly used on the outer walls of tall multi-storey buildings. This lightweight material offers ease of installation and can be customized to be glazed, opaque, or equipped with infill panels. Its strength lies in enabling transparency and scale: framing floor-to-ceiling glass, reducing structural weight, and creating a high-performance building envelope.
